Mercedes-Benz has conducted a lifecycle assessment of its new C-Class C 300 e plug-in hybrid sedan, taking into account production and charging processes. The production of additional drivetrain components for the vehicle requires greater use of material and energy resources, but during the operating phase, the car benefits from the high efficiency of the electrified powertrain. With a usable energy capacity of approximately 25 kWh and an electric output of 95 kW, the car can cover distances of up to 116 km in all-electric mode without using the combustion engine.

Mercedes-Benz analyzed the charging of the high-voltage battery based on two different energy sources: renewable sources (electricity from hydropower) and the European power mix. The results showed that if renewable power is used to charge the C 300 e, lifecycle CO2 emissions can be almost halved. Mercedes-Benz is also building a battery recycling plant in Germany with a process that will achieve a recovery rate of over 96%. The company-owned Mercedes-Benz car and van plants worldwide have operated on a net carbon-neutral basis since 2022, and since 2021, the company has ensured a subsequent offset with green electricity when customers use Mercedes me Charge public charging stations in Europe, the USA, and Canada.

Important factors for the lifecycle assessment of a plug-in hybrid vehicle include the resources consumed in production and the charging processes of the high voltage battery during vehicle operation. In production, the additional drivetrain components of the new Mercedes-Benz C-Class C 300 e plug-in hybrid sedan (WLTP: combined fuel consumption, weighted: 0.7–0.5 l/100 km, combined CO₂ emissions, weighted: 16– 2 g/km, combined electrical power consumption, weighted: 19.8–17.8 kWh/100 km)[1] require a greater use of material and energy resources. However, an overall picture only emerges when the entire life cycle is considered: This is because during its operating phase, the C 300 e benefits from the high efficiency of the electrified powertrain.

Data, facts and figures: The lifecycle performance of the C 300e plug-in hybrid at a glance
Mercedes-Benz based its analysis of the charging of the high-voltage battery on two different energy sources: One scenario is based on power from renewable sources (electricity from hydropower)[2], and the other on the European power mix2. Both scenarios are based on a mileage of 200,000 km. The result: If renewable power (hydroelectric power) is used to charge the C 300 e, lifecycle CO2 emissions can be almost halved.

With the increased electric range (WLTP) brought about by the C 300 e battery and its usable energy capacity of approximately 25 kWh and an electric output of 95 kW, the car can cover distances of up to 116 km[3] in all-electric mode without using the combustion engine.

210 components with a total weight of 90.4 kg can be made in part with materials that result in lower consumption of resources (recycled plastics and renewable raw materials).

Mercedes-Benz is building a battery recycling plant in Kuppenheim in southern Germany with a process that will achieve a recovery rate of over 96%.

All company-owned Mercedes-Benz car and van plants worldwide have operated on a net carbon-neutral basis since 2022.

Since 2021, Mercedes-Benz has ensured a subsequent offset with green electricity when customers use Mercedes me Charge[4] public charging stations in Europe, the USA and Canada. Certificates of origin ensure that corresponding amounts of green electricity are fed into the grid for charged energy quantities after the charging process.

Mercedes-Benz is using an exceptional campaign to show the benefits of its Plug-In Hybrid technology. Both the C 350 e and the MERCEDES AMG PETRONAS Team’s current F1 car embody the headline ‘Success has two sides. More electricity. Less fuel. ‘Both the racing car and the series model are the product of ground-breaking, new technologies. The campaign shows how Mercedes-Benz brings innovative hybrid technology from the race track to the street so everyone can experience it.

Mercedes-Benz

The international campaign consists of six print motifs and a TV commercial. In the print motifs, the C 350 e presents itself far away from the city on forgotten streets which run through a prohibited area. The streets are rough and dusty – the perfect testing ground for hybrid technology. Here, the benefits of the C 350 e come to the fore: efficient, dynamic and comfortable. Extreme perspectives bring the benefits to the fore in the motifs. The print campaign will run until September 30th, 2015.

The C 350 e, the second Plug-In Hybrid model that Mercedes-Benz is introducing after the S-Class, convinces with its exceptional dynamism and efficiency. The vehicle allows up to 31 kilometres of electric and thus locally emission-free driving. Its four-cylinder petrol engine, in conjunction with a powerful electric motor, gives it a total system output of 205 kW (279 hp) with a system torque of 600 Nm. The new C 350 e thus delivers the performance of a sports car while offering a certified consumption of just 2.1 litres of fuel per 100 kilometres in both its saloon and estate variants.

Powerful with Nico Rosberg and Lewis Hamilton

The TV commercial shows a dynamic drive from the driver’s perspective through tight corners and long straights. A second vehicle keeps appearing. The viewer sees an exciting neck-and-neck race. At the end of the drive, we see both cars stopped in front of a parking garage. A voice-over says ‘The two best driver’s in the world…’. One of the drivers sticks his arm out and up in an attempt to pull the ticket. We recognize Lewis Hamilton. He’s sitting in his F1 car in front of the barrier. Nico Rosberg is beside him at the second barrier in the C 350 e. He clearly has the advantage and confidently takes out the ticket, puts on his winner’s smile and disappears into the dark parking garage. But Hamilton doesn’t give up. He quickly closes his visor, accelerates and drives underneath the barrier. The voice-over adds ‘…and one winner: hybrid technology by Mercedes-Benz.’

The new Mercedes-Benz S550 PLUG-IN HYBRID blends an ultramodern hybrid drive configuration with the unique innovations and the luxurious equipment and appointments of the S-Class. The luxury sedan impresses with exceptional dynamism and efficiency. Thanks to standard pre-entry climate control it also offers unique climate comfort. The first certified three-liter luxury sedan in the world is a further milestone on the road to emission-free mobility.

Mercedes-Benz S550 PLUG-IN HYBRID

“The S550 PLUG-IN HYBRID is the first luxury sedan with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive,” says Prof. Dr. Thomas Weber, member of the Daimler Board of Management responsible for Group Research and Mercedes-Benz Cars Development.

“The new S550 PLUG-IN HYBRID offers our customers the entire range of innovations that make our new S-Class so successful, and thanks to its intelligent operating strategy ensures outstanding driving pleasure and dynamism combined with the highest efficiency. Moreover, it allows completely emission-free driving for up to 20 miles,” adds Ola Källenius, Executive Vice President Sales and Marketing Mercedes-Benz Cars.

The Mercedes-Benz S550 PLUG-IN HYBRID offers a system output of 436 hp and 479 lb-ft torque, sprints from 0 to 62 mph in just 5.2 seconds and can drive up to 20 miles purely electrically. Key elements of this impressive output are the V6 biturbo and the intelligent hybrid drive. The new high-voltage lithium-ion battery with an energy content of 8.7 kWh can be externally recharged via the charging socket in the right side of the rear bumper.

The S550 Plug-In Hybrid model has environmental certificates. These document the model’s environmental performance from development through to recycling across the entire lifecycle, and the performance is certified to internationally recognized standards by independent experts.

Regarding CO2 emissions, the certificate of the S550 PLUG-IN HYBRID states: “Over the entire lifecycle encompassing manufacture, use of over 300,000 kilometres (186,000 miles) and recycling, clear advantages result when compared with the S550. External charging with the European electricity mix can cut CO2 emissions by some 43 percent (35 tonnes). Through the use of renewably generated hydroelectricity a 56 percent reduction (46 tonnes) is possible.”

The hybrid transmission is based on the 7-speed automatic transmission. The plug-in-hybrid system in the S-Class is based on the Mercedes-Benz parallel hybrid modular system. The common system-specific feature is the additional clutch integrated between combustion engine and electric motor. On the one hand, it decouples the combustion engine during purely electric operation; on the other hand, if the combustion engine is employed it affords the possibility to move off drawing on the performance of a wet start-up clutch. The clutch then substitutes for the torque converter and requires no additional space owing to its complete integration in the torque converter housing.

Haptic accelerator pedal: support for the driver

Climb in, start, drive off and, as well as exemplary efficiency, on request experience via kickdown the special acceleration of the electric motor – this is how easy hybrid driving is with the new S550 PLUG-IN HYBRID. For in everyday use it moves just as easily as any other automatic transmission car.

In the background, depending on the chosen operating mode, the intelligent operating strategy automatically selects the ideal combination of internal combustion engine and electric motor and in so doing not only adapts its strategy according to the charge status of the battery; it also foresightedly adjusts it according to the traffic or route. Anyone wanting to can also intervene manually and with the aid of four operating modes and three transmission modes regulate the hybrid interplay themselves.

What is known as the haptic accelerator pedal can signal via a double impulse when drivers should take their foot off the accelerator for sailing and recuperating. During electric operation it can supply the driver with feedback on the switch-on point of the combustion engine. The energy flow can be shown in all operating states in the instrument cluster and in the central display if this is selected by the customer.

Extensive standard equipment, extended pre-entry climate control

The standard equipment in the S550 PLUG-IN HYBRID is extensive and offers a world premiere: theextended pre-entry climate control. This is target value controlled, meaning that at the start of the journey the S-Class is air conditioned to the preset temperature if the driver has entered the departure time via the S-Class Vehicle Homepage. This is possible due to the electrically driven refrigerant compressor and electric heating elements for the heated air. In addition, when preheating it is not just the interior air but also the seats, steering wheel and armrests in the doors and center console which are heated, and when cooling the seat ventilation is also activated if the respective optional extra is on board.

Also standard on the S550 PLUG-IN HYBRID are LED High Performance headlamps and LED tail lights, leather upholstery, COMAND Online, touchpad, dual-zone Automatic climate control, Memory package for driver and front passenger, ambient lighting in seven colors and the air suspension AIRMATIC with continuously variable damping system. The basic safety equipment includes PRE-SAFE®, COLLISION PREVENTION ASSIST PLUS (collision warning including Adaptive Brake Assist), ATTENTION ASSIST, PRE-SAFE® impulse, and Crosswind Assist.

The Mercedes-Benz hybrid strategy: emphasis on plug-in drives

The S550 PLUG-IN HYBRID is the first hybrid model in the U.S. for the new S-Class. The series production launch of this technology began at Mercedes-Benz in 2009. The company is among the leaders in the field of purely electric mobility, and in the years to come the main emphasis will be on plug-in hybrids.

Hybrid drives, the combination of internal combustion engine and electric drive, help cut overall fuel consumption and boost performance since the electric drive replaces or supports the combustion engine whenever the engine characteristics are unfavorable — normally in part-load operation when little power is required.

The largest potential for lowering the energy consumption of the hybrid drive systems lies in maximizing energy recovery during coasting and braking. Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The hybrid models of the new S-Class are the first to use a recuperative braking system of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in generator mode.

Intelligent operating strategy

For efficient operation, foresighted driving, avoiding unnecessary braking and accelerating maneuvers have always been the best strategy. This gains an all new importance in a hybrid model: braking maneuvers serve not only deceleration, but can also be used to recuperate energy. In addition, the route has considerable influence on the most efficient charging and discharge of the high-voltage battery.

The intelligent operating strategy supports the driver comprehensively yet unobtrusively to achieve the most efficient driving style. The control strategy, for example, seeks to ensure that the battery, if at all possible, is flat at the end of an uphill stretch so that it can be recharged going downhill. Another key point is the requirement that urban areas be reached with a fully charged battery, if possible, so that the vehicle can be operated in stop-and-go traffic electrically – frequently and efficiently.

In the S550 PLUG-IN HYBRID the energy management system covers these three areas:

• route-based: automatically or by way of four operating modes
• driver-based: by way of three transmission modes
• traffic-based: with the aid of radar.

Mercedes-Benz S550 PLUG-IN HYBRID

Charging: power from a socket

The battery of the S550 PLUG-IN HYBRID is safely fitted into the rear end of the S-Class to save space. An intelligent on-board charging system enables the battery to be charged at any conventional household power socket. The supply of electricity to the car will be made even easier in the future through inductive, cableless charging.

The S550 PLUG-IN HYBRID stores electric energy in a lithium-ion battery on lithium-iron phosphate basis. The water-cooled energy storage unit has an overall capacity of 8.7 kWh, a total weight of 251 lbs and a spatial volume of 3.4 cubic feet.

To ensure the highest levels of crash safety and dynamic handling and also maximum trunk space, the housing is made of die-cast aluminium and the high-voltage battery is located in the rear of the vehicle above the rear axle. The space available there is put to optimal use, and the S550 PLUG-IN HYBRID thus takes first place among the plug-in hybrids in terms of trunk capacity (12.2 cubic feet) and luggage compartment accessibility.

The high-voltage battery of the S550 PLUG-IN HYBRID can be charged via external electricity mains using a 3.6 kW on-board charger. The unit is permanently installed in the vehicle and charges single-phase up to 16 A. The connection for the charging cable is located under a flap of the rear bumper underneath the tail light on the right-hand side. An automatic lock ensures that the cable cannot be separated from the vehicle by unauthorized persons. The new S-Class can be charged in two hours anywhere in the world, e.g. at a wallbox or a charging pole (400 V, 16 A). Alternatively, charging via house connection is also possible. Depending on the connection a charge of time e.g. of two hours and 45 minutes can be attained (with 230 V and 13 A).

Thanks to our good friends over at GMotors, we have the latest and best spy shots of the C-Class Plug-In Hybrid testing undisguised near Stuttgart, Germany.

The plug-in hybrid version of the C-Class reveals a revised front bumper and a new active shutter grille, along with updated rear bumper with an integrated charging port similar to the one on the new S-Class plug-in hybrid.

Nothing new is shown in the interior image, but you can expect the COMAND system to be updated with hybrid-specific driving information.

The plug-in hybrid system is rumoured to use a 2.0-litre petrol turbo working together with a 68bhp electric motor, delivering up to 94mpg.

Mercedes-Benz has developed an intelligent energy management system for hybrid vehicles that assesses the road ahead and takes it into account. The objectives of the “Intelligent HYBRID”: benefiting from the freely available recuperation energy to the greatest extent possible and providing driving pleasure thanks the boost effect of the electric motor. To this end it constantly monitors the topography ahead of the vehicle. This not only works when route guidance by the navigation system is active, but also when this system is currently not in use. In developing new hybrid models Mercedes-Benz has benefited immensely from cooperating with its Formula 1 racing team, which also makes use of high-tech hybrid engines to achieve fuel savings. This can result in synergistic effects both for series production vehicles as well as racing cars.

Many hybrid vehicles waste energy when driving downhill. Because frequently their high-voltage battery has too high a charge at the wrong time to be able to additionally store the incidental free recuperation energy associated with driving downhill. The “Intelligent HYBRID” operating strategy, which Mercedes-Benz has employed in the S-Class since summer 2013 and now also uses in the new C-Class, ensures that the high-voltage battery is always only charged sufficiently enough to take advantage of all opportunities for recuperation provided by the route and the terrain.

In practice this means: if the battery is too full, the electric motor automatically boosts the combustion engine to discharge the battery enough to be able to fully store the expected recuperation energy. At the same time, thanks to the boost from the electric motor the vehicle uses less fuel and thus produces fewer emissions during this phase.

The system uses data from the COMAND Online navigation system to calculate the recuperation potential of the road ahead. For example, the data provides forward-looking information about the route profile and speed limits in a one-metre grid for up to seven kilometres in advance.

This information is processed by the Central Powertrain Controller (CPC), which then initiates the anticipatory measures. It not only lowers the battery charge in line with the situation before a downhill stretch by expanding the all-electric or boost periods, but also controls the potentially necessary recharging of the battery by the combustion engine with foresight in order to benefit from the most favourable battery state of charge. Further adaptive control algorithms additionally take the current vehicle weight, the driving behaviour (including vehicle speed and braking behaviour) and the load of the ancillary consumers into account for predicting the recuperation potential.

“Intelligent HYBRID” not only works as the only anticipatory operating strategy when a destination has been programmed into the navigation system, but also functions when route guidance is inactive. In this case the system calculates the probability of the driver making a turn dependent on the category of the road. For example, if the hybrid vehicle is travelling on a motorway, it assumes that the vehicle will probably continue on the motorway for the next seven kilometres.

“Intelligent HYBRID” keeps the driver informed about an upcoming elevated recuperation potential by highlighting the road ahead of the vehicle in green on the energy flow display.

How much fuel is being saved depends on the topography. This has been demonstrated by experience from many thousands of test kilometres. The more mountains there are, the higher the fuel savings will be. That is why the effect will be more noticeable in the mountains than on plains.

Currently Mercedes-Benz is becoming a talking point in the world of Formula 1 by deploying racing cars featuring hybrid technology. After Nico Rosberg triumphed at the opening race in Australia, there have been two one-two victories in Malaysia and Bahrain. In each case Lewis Hamilton finished ahead of Nico Rosberg. The next race takes place on 20 April in the Chinese metropolis of Shanghai.

Mercedes-Benz has officially announced the 2014 S 500 PLUG-IN HYBRID.  The newest S-Class model is cheduled to make its public appearance next month at the Frankfurt Motor Show the luxury hybrid will hit dealerships next year. The S-Class is a luxury car through and through, it’s big and heavy, making it all the more impressive that Mercedes was able to use an 80-kW electric drive with externally rechargeable battery to allow for emission-free in-town driving up to nearly 20 miles. Combined with Mercedes’ new 3.0-litre V6 turbocharged engine and the 2014 S500 PLUG-IN HYBRID averages 69 g CO2 per kilometre (3 litres/100 km).

On the road to emission free driving

The S 400 HYBRID was the first in the world to feature a standard-specification hybrid drive system with lithium-ion battery in 2009. With the new S-Class Mercedes-Benz expands the hybrid line-up in this model series to three models: the S 400 HYBRID, S 300 BlueTEC HYBRID and S 500 PLUG-IN HYBRID. All second-generation hybrid drive systems share the seamless integration into the powertrain. The combustion engine can be completely decoupled from the electric motor. Further features are the second-generation recuperative braking system and the anticipatory Intelligent HYBRID energy management system.

“With the S 500 PLUG-IN HYBRID Mercedes-Benz sets another milestone on the road to emission-free mobility on the basis of our modular hybrid matrix”, explains Prof Dr Thomas Weber, responsible on the Daimler Board of Management for Group Research and Head of Mercedes-Benz Cars Product Engineering. “In this way the S-Class turns into a genuine three-litre car with generous space and superlative drive-system comfort.”

While the batteries of the S 400 HYBRID and S 300 BlueTEC HYBRID as autonomous hybrids are charged during braking or coasting or by the combustion engine, the new high-voltage lithium-ion battery of the S 500 PLUG-IN HYBRID has ten times the energy content and offers the option of being recharged from an external source with a charging socket located on the right side of the rear bumper. With the help of the electric synchronous motor (80 kW/340 Nm) the S-Class can thus drive for up to around 30 kilometres on electric power alone.

2014 Mercedes S500 Plug-In Hybrid Interior

Four hybrid operating modes can be selected at the push of a button:

• HYBRID

• E-MODE: electric power only

• E-SAVE: fully charged battery is reserved to be able to drive on electric power alone later

• CHARGE: battery is charged while driving

Under the conditions specified by the certification rules the S-Class as a full hybrid generates 69 g CO2 per kilometre. With consumption equivalent to 3 litres per 100 kilometres the S-Class sets a new benchmark for luxury saloons that just a few years ago was thought virtually impossible. It delivers these top values without restrictions in power, passenger comfort or operating range and offers a high level of climate comfort thanks to the pre-entry climate control functions.

2014 Mercedes S500 Plug-In Hybrid Battery

The most important benchmark data of the S 500 PLUG-IN HYBRID:

• Power output of 245 kW of the combustion engine plus 80-kW electric motor and torque of 480 Nm of the combustion engine plus 340 Nm of the electric motor

• Overall consumption (NEDC) 69 g CO2/km (3.0 l/100 km)

• Operating range on electric power alone about 30 km

• Top speed 250 km/h, 0-100 km/h in 5.5 sec.

• Intelligent HYBRID: anticipatory energy management system with optimal use of recuperation during deceleration

• Individualisation possible as the result of the combination of the transmission modes with the four hybrid operating modes – HYBRID, E‑MODE, E-SAVE and CHARGE.

• Haptic accelerator pedal for superior vehicle control: A point of resistance on the accelerator pedal provides feedback about the activation of the combustion engine and helps in metering the power output.

• Fast external charging of the high-voltage traction battery

• Pre-entry climate control of the interior

Intelligent HYBRID: anticipatory energy management system

The second-generation S-Class hybrids feature an anticipatory energy management system and thereby improve energy efficiency. The operating strategy of the hybrid drive system not only accounts for the current driving condition and driver input, but also adjusts to the likely route (inclines, downhill stretches, bends or speed limits) for the next eight kilometres. Intelligent HYBRID uses the navigation data from COMAND Online to manage the charging and discharging of the high-voltage battery. The goal is, for example, to use the energy content of the battery for propulsion ahead of a downhill stretch in order to recharge it while going downhill using recuperation.

2014 Mercedes S500 Plug-In Hybrid Charging

Recuperative braking system: the electric motor as alternator

The largest potential for lowering the energy consumption of hybrid drive systems lies in maximising energy recovery during coasting and braking. Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The new S-Class is the first to use a recuperative braking system (RBS) of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in alternator mode.

The driver’s desired braking power is recorded by a pedal-travel sensor. The deceleration is dependent on the driving condition and is split into a recuperative brake-force portion and a portion to be supplied by the wheel brakes. The brake pressure on the rear axle is controlled by the RBS dependent on the current recuperation potential of the powertrain.

In addition, the combustion engine is switched off any time the vehicle is coasting and its drag torque when rolling is used by the electric motor as recuperation torque. However, without depressing the brake pedal no additional deceleration torque is provided for charging the battery and the vehicle can “sail”. The combustion engine is to be used for charging the battery as little as possible and only at suitable and most efficient operating points.

Hybrid pioneer in the luxury segment

The world’s first standard-specification hybrid drive with lithium-ion battery debuted at Mercedes-Benz as early as 2009: the S 400 HYBRID was the most fuel-efficient petrol-powered luxury saloon for a long time. And the most successful hybrid in its segment: some 20,000 buyers worldwide opted for the S 400 HYBRID.

With the new S-Class Mercedes-Benz now continues its comprehensive hybrid offensive. In the S 400 HYBRID and S 300 BlueTEC HYBRID there are already two hybrids of the new S-Class to choose from:

• The new S 400 HYBRID burns just 6.3 litres of fuel per 100 kilometres in the NEDC cycle (combined). This represents a reduction by 20 per cent over the predecessor. CO2 emissions of 147 grams per kilometre also represent a new record in this vehicle segment. These exemplary figures go hand in hand with outstanding performance potential: the petrol engine develops 225 kW (306 hp), while the electric motor adds another 20 kW (27 hp). The torque of the combustion engine is 370 Nm plus 250 Nm from the electric motor.

• In the S 300 BlueTEC HYBRID Mercedes-Benz has combined the 2.2‑litre four-cylinder diesel engine developing 150 kW (204 hp) with the powerful hybrid module developing 20 kW (27 hp). The peak torque of 500 Nm produced by the combustion engine is overlaid by the 250 Nm of peak torque produced by the electric motor. The S 300 BlueTEC HYBRID makes do with 4.4 litres per 100 km in the combined cycle (CO2: 115 g/km) and complies with the criteria for energy efficiency class A+. Consequently Mercedes-Benz has, over the course of ten years, nearly cut fuel consumption in the 150-kW performance class by half.

Just when you thought the 2014 Mercedes S-Class couldn’t get any better, rumor has it that a plug-in hybrid version is scheduled to debut at the Frankfurt motor show in September. Meaning that for all of the climate concerned drivers out there, you don’t have to settle for less than the very best anymore.

The S-Class Mercedes would emit CO2 emissions around 70g/km, lower than any other green luxury saloon, currently holding that title is the Porsche Panamara Hybrid with 71 g/km.  To put The S500 Plug-in Hybrid’s amazing numbers in perspective, two of the three Prius models have higher CO2 emissions with 89 g/km and 96 g/km and  the vehicles aren’t even remotely comparable.

The S-Class Hybrid will use a V6 gasoline engine in conjunction with an electric motor and a battery pack that will be mounted in the trunk that will allow drivers to get around 75 mpg in the U.S.

Stay tuned for more information on the new Plug-in Hybrid S-Class and in the meantime, check out the 2014 S-Class photo gallery(click) to see in-part what makes it so special.

Good morning everyone and happy Friday. The latest news to hit the web regarding the highly anticipated 2014 Mercedes-Benz S-Class come from an inadvertent admission by Mercedes themselves during a media presentation. What’s the big news? Confirmation of a plug-in hybrid version of the new S-Class.

The media presentation, held in Sindelfingen, Germany, was hosted with the purpose of showing off the new S-Class’ user interface system. Screenshots of the TFT instrument panel showed an “E Drive” mode along with a battery usage gauge. Also shown off during the presentation was a graphic that showed the S-Class drive-train schematic with an electric motor located behind the engine, with a battery pack mounted in the boot.

Not surprising of course, the 2014 Mercedes-Benz S-Class hybrid has yet to be officially confirmed and Mercedes will not comment on whether the photos shown during the presentation signify their intent to produce a Hybrid S-Class. According to spokesmen Jerry Stamoulis, until the S-Class’ official debut on May 15, no drive-train information will be revealed. We can say however with pretty good certainty that Mercedes will have a Hybrid S-Class in the 2014 lineup.

Daimler unveiled their F-CELL Roadster back in 2009, it was the latest in their line of “F-Series” concept vehicles (past Mercedes research models can be seen here), and as you’ll see, it drew its inspiration from a diverse variety of automotive eras.  From a functional standpoint, it’s a roadster fitted with a 1.2 kW hybrid drive – one that allowed the F-CELL to reach a top speed of 15 mph and achieve an operating range of  217 miles.  From a design standpoint, however, is where the F-CELL Roadster truly shined, as it managed to blend the overall aura of the original Benz patent motor car with the seating and fiberglass front section both drawn from elements of Formula One racing.

As for who was responsible for creating the unique F-CELL Roadster, that honor went to the trainees of of Daimler AG at the Sindelfingen plant, with more than 150 trainees and dual education system students having worked for about a year on the overall concept, development, assembly, and completion of the hybrid model.  According to Human Resources Board member and Labor Relations Manager Günther Fleig in 2009:  “This project impressively demonstrates that the topic of sustainable mobility has become an integral part of our vocational training.  I am delighted to see how much initiative and creativity the young people have put into this project.”

Mercedes-Benz launches hybrid offensive with the world’s most economical luxury vehicle.

• E300 BlueTEC HYBRID: 4.2 l of diesel/100 km
• E400 HYBRID: combined fuel economy of 27 mpg (estimated)
• More torque and performance without compromising on passenger or luggage space
• Modular hybrid concept using lithium-ion batteries
• Sophisticated driving experience with stop/start function, regenerative braking, boost effect and pure electric driving

Mercedes-Benz is opening a new chapter in its core segment while at the same time setting new standards for luxury sedans. The E300 BlueTEC HYBRID (European model) impresses with new record values when it comes to efficiency. It boasts exemplary consumption levels (4.2 l/100 km1) as well as impressive performance: the E300 BlueTEC HYBRID combines a 4-cylinder diesel engine developing 201 hp and 369 lb-ft of torque with an electric motor producing 27 hp and 184 lb-ft. The E300 BlueTEC HYBRID is the most economical luxury vehicle in the world.

Available in the U.S. during the 2nd half of 2012, the 2013 E400 HYBRID features a direct-injection V6 gasoline engine producing 302 hp and 273 lb-ft supplemented by an additional 27 hp and 184 lb-ft from the electric motor. The estimated consumption figures are: 24 mpg city, 31 mpg highway, and 27 mpg combined.

“With these two E-Class models we are now continuing our comprehensive hybrid offensive. The modular technology opens up a quick way for us to complement other model series with hybrid models”, explains Professor Dr. Thomas Weber, Daimler Board Member for Group Research and Head of Mercedes-Benz Cars Development. “With a clear focus on the different requirements of global markets, we are able to offer precisely the models which our customers want. The E-Class hybrids provide a clear reduction in consumption as well as a very impressive driving experience: they represent hybrid motoring at the premium level.”

The new models do not require their passengers to compromise when it comes to space, however, whether in terms of the interior or the luggage compartment. There are also additional benefits to the intelligent modular hybrid concept, which builds upon the Mercedes-Benz S400 HYBRID that debuted in 2009: no changes to the vehicle body are required, the hybrid module is both flexible and modular, thus allowing its use in other model series, and in addition to diesel and gasoline powertrains there will also be right-hand drive variants. Meanwhile, the extra cost involved is only moderate. The new hybrid models will celebrate their world premiere at the Detroit Auto Show (January 14-22, 2012) and will appear on the market over the course of the year. The 2013 E400 HYBRID goes on-sale in the U.S. during the 2nd half of 2012 followed by other countries such as Japan and China, while the E300 BlueTEC HYBRID is initially planned to be launched in Europe.

Highlights of the E400 HYBRID at a glance:

• Compact, intelligent and modular hybrid configuration: no changes to the body of the E-Class are necessary
• No compromises in terms of passenger or luggage space, safety and comfort
• Significant increase in comfort with stop/start operation; noiseless start, complete climatic comfort
• Estimated fuel consumption: 27 mpg (combined)
• Part of the intelligent downsizing strategy of Mercedes-Benz: increase in the engine output of the E400 HYBRID by some 27 hp and 184 lb-ft thanks to the electric motor
• Sophisticated hybrid driving experience (stop/start function, regenerative braking, boost effect and pure electric driving)

Highlights of the E300 BlueTEC HYBRID (European model) at a glance:

• Compact, intelligent and modular hybrid concept: no changes to the body of the E-Class are necessary
• Also available as a Wagon (in Europe)
• Space, safety and comfort remain unchanged
• Significant increase in comfort with stop/start operation; noiseless start, complete climatic comfort
• Top marks for consumption in the luxury-class business vehicle segment: 4.2 litres/100 km, 109 g CO2/km
• Part of the intelligent downsizing strategy of Mercedes-Benz: increase in the engine output of the E300 BlueTEC HYBRID with 150 kW +20 kW electric motor/500 Nm + 250 Nm, compared with the E250 CDI (150 kW/500 Nm), positioning it at the same level as the E300 CDI (170 kW/540 Nm)
• Fuel savings of around 15 percent compared with the E250 CDI (european model)
• Sophisticated hybrid driving experience (stop/start function, regenerative braking, boost effect, and pure electric driving)

According to a report by Autocar, the next-generation Mercedes-Benz C-class will offer hybrid technology on nearly every model variant in an attempt to lower the average fuel consumption down to supermini levels.  This is according to sources within the company.

The new Mercedes C-Class family is being developed to meet demanding CO2 targets and is expected to launch in late 2013. According to a Mercedes insider, the most frugal diesel-engined model in the range is targeting average emissions of just 100g/km, while the most economic petrol version will come in between 110g/km and 120g/km.

Early prototypes are now being tested, but according to Autocar there is still some debate as to whether three-cylinder engines will be fitted. Another possibility is that the new cars will use four-pot engines equipped with cylinder deactivation technology, allowing the motors to occasionally run on just two cylinders.

In addition to these downsized engines and electrical assistance from hybrid transmissions, the new C-Class models will benefit from reduced friction within the engine, gearbox and wheel bearings. The cars’ overall weight, even with the addition of a small battery pack, electric motor and power electronics, will be reduced by around 10 percent.

In 2008, RENNtech unveiled the GLK350 Hybrid Pikes Peak Rally Car, a concept vehicle which won the 2008 SEMA Show Mercedes-Benz tuner build off competition. This vehicle was designed not only to turn heads as a show car, but to serve as a proof-of-concept and testament to their dedication to a core concept; performance without compromise. Fast forward nearly 3 years, countless automotive trade shows, numerous track events and extensive real world miles; the GLK Pikes Peak project has been completely revamped and restyled for a final tour in 2011 with Mercedes-Benz USA.

Upon completion of the US tour schedule, the GLK will retire to a place of honor in the Mercedes-Benz Classic Vehicle Museum located in Irvine, CA as part of their permanent collection. This will be the second vehicle prepared by RENNtech that has found its way into the hallowed halls of the Mercedes-Benz Museum Collection, the first of which was the E60 RS project car built for comedian Jerry Seinfeld.

When approached with the opportunity, RENNtech completely revamped the vehicles exterior and collaborated once again with 3M Commercial Graphics Division to complement the GLK’s aggressive exterior styling. This original body kit was entirely designed and engineered by RENNtech in-house, using the latest in Computational Fluid Dynamics (CFD) software and rapid prototype capabilities. The concept behind the restyling was to not only completely change the vehicles appearance, but utilize vinyl materials in finishes rarely seen in the automotive world. 3M chose the RENNtech GLK as the showpiece to revel their latest product line of 1080 Scotchprint ® textured automotive vinyl wrap. This preprinted, 3.5 mil dual cast film was applied to nearly every exterior surface of the vehicle in a stunning combination of brushed steel (1080-BR201) and black carbon fiber (1080 CF-12) with subtle red pin stripping to further accent the vehicles bold lines.

The GLK350 Pikes Peak Project was unveiled to the public during Mercedes-Benz’ first leg of their tour schedule at the Pittsburgh International Automotive Show February 10-13th, 2011. Additional stops on the tour schedule include Milwaukee, Cincinnati, Cleveland, Kansas City, Minneapolis and Denver. After its time on the road, the vehicle can be seen at the Mercedes-Benz Classic Vehicle Museum in Irvine, California.

RENNtech worked with and was supported by several companies that can be seen below.

• Mercedes-Benz
• 3M
• KW Suspensions
• Geoff’s Curtain Walls
• Nitto Tires
• Optima Batteries
• JRD
• Schroth Racing
• Technicar
• Seibon

According to Herbert Kohler, head of Daimler’s E-Drive and Future Mobility unit, Daimler is moving quickly on hybrid technologies and will offer hybrid versions of its Mercedes-Benz C-Class, E-Class and S-class vehicles in the United States and Europe within three years.  All this in an effort to meet tightening global fuel economy standards. “We have a leading position in the premium segment concerning alternative propulsion systems, and we will defend it,” Kohler said after a press event.

Another source at Daimler said the C-Class and E-Class hybrids will be launched in Europe before 2013 and the S-class plug-in hybrid will be launched in 2014, with the U.S. versions of the hybrid vehicles to follow six months later.

Currently Mercedes does not offer a plug-in version of its vehicles in the United States; instead, the Mercedes S400 is offered as a mild hybrid and the M-Class as a full hybrid.  To differentiate, a mild hybrid uses an electric motor and acts as a start/stop system, but the electric motor does not drive the vehicle by itself, whereas a full hybrid can be driven short distances using the electric motor.

As the Official Vehicle of the US Open, Mercedes-Benz USA that it is a driving force behind the USTA’s commitment to green initiatives by providing Mercedes-Benz S400 HYBRID sedans and Mercedes-Benz F-CELL (Hydrogen Electric Vehicle powered by a fuel cell) vehicles representing 60 percent of the fleet used for player and VIP transportation during the 2010 US Open tournament.

As an innovator in luxury eco-transportation, Mercedes-Benz is dispatched its F-CELL hydrogen fuel vehicles with zero emissions in addition to 75 S400 HYBRID vehicles in an effort to reduce the overall carbon footprint of the US Open tournament. The US Open launched its comprehensive environmental program three years ago and continues to expand green initiatives each year. In 2010, key initiatives include recycling, energy management, composting and utilizing paper products comprised of at least 30% post-consumer waste. In addition, a new green PSA campaign is planned featuring Alec Baldwin.

“We are very excited to participate in the USTA’s environmental strategy and positively impact the US Open green initiatives through the Mercedes-Benz transportation fleet. By tapping our portfolio of eco vehicles, we can provide athletes, staff and officials with green transportation without having to sacrifice luxury or safety,” said Stephen Cannon, Vice President of Marketing for Mercedes-Benz USA. “Over the next four years, Mercedes-Benz is committed to exploring new ways through innovative eco mobility to help the USTA expand their environmental initiatives.”

MERCEDES-BENZ S400 HYBRID

The S400 HYBRID features the world’s first lithium-ion battery designed specifically for automotive use. The light-weight, high-capacity lithium-ion battery works with a 20-horsepower electric motor and a 275-hp V6 gasoline engine to provide hybrid power with impressive fuel economy estimated at 30 miles per gallon on the highway making it the clear GREEN choice for the US Open transportation fleet.

An added bonus of driving green cars like the Mercedes-Benz Hybrid, beyond not sacrificing space, safety or luxury, is the IRS alternative-powertrain tax credit. The Mercedes-Benz hybrid credit for the S400H is $1150. The current tax credit for the S400 HYBRID is $1150.

MERCEDES-BENZ F-CELL

Essentially an electric car that makes its own power on board, the new Mercedes-Benz F-CELL has a range of about 240 miles refueling with refueling taking only a few minutes. Running on compressed hydrogen, the F-CELL boasts an equivalent fuel mileage of 71.3 city-highway combined miles per gallon and water is the F-CELL’s only emission.

Environmental friendliness, efficiency, and passenger safety will be the focus of new developments for Mercedes-Benz buses and coaches. At the 63rd IAA Commercial Vehicles, in Hall 14/15 Sept. 23-30, 2010, five travel coaches and transit buses will be presented to the public. Among them will be the innovative, zero-emission Citaro FuelCELL Hybrid, and the Mercedes-Benz Sprinter City 77 for urban use which will be making its debut at the auto show.

New Sprinter City 77: innovative flagship urban bus joins the minibus line-up

This minibus is XXL: Mercedes-Benz caps its urban minibus range with the new Sprinter City 77. The three-axle 8.7-metre-long urban bus is based on a conventional Sprinter up to the B-pillar. The bus body with twin rear axle and continuous low-floor area is an exclusive in-house development for the Sprinter City 77. Thanks to its capacity of 40 passengers it plugs the gap between the Sprinter City 65 and the Citaro K. The new Sprinter City 77 is around a metre longer than the previous City 65 flagship model and – depending on the equipment options – boasts ten extra passenger seats. The gross vehicle weight of 6.8 t facilitates the high passenger-handling capacity.

Two outward-swinging double doors, which are operated using an innovative drive concept, and a kneeling function along with the stepless low floor throughout ensure fast passenger flow and convenient boarding and alighting. Depending on the configuration a wheelchair bay with a ramp is available at the front or rear. The bright interior with its large windows and large glass doors is spacious and attractive.

The Sprinter City 77 has a wheelbase of 4100 + 990 mm. The air-sprung rear axles feature 235/65 R 16 C single tyres all-round. The relatively short wheelbase and the sleek design make the minibus extremely manoeuvrable: the width of the separately mounted body is just 1.99 metres, making the largest member of the Mercedes-Benz minibus line-up likewise ideally suited to tight inner city areas. Moreover, it is also an ideal solution as a shuttle bus for airports or trade fairs, as well as for rural services.

A Mercedes-Benz Sprinter with the most powerful version of the four-cylinder diesel engine provides the platform. Its output of 120 kW (163 hp) and maximum torque of 360 Nm delivers appropriate performance. The Sprinter City 77 is among the cleanest on the block with its EEV emissions standard certification. Power transfer comes courtesy of a convenient fully automatic 5-speed transmission as standard.

Most Mercedes-Benz vehicles are available with the world’s first seven-speed automatic transmission, which simultaneously improves fuel economy and acceleration as well as making smooth, barely noticeable gearshifts. A number of model families also come equipped with a convenient Direct Select shift lever on the steering column, which provides more convenient Touch Shift operation and at the same time, opens up valuable space on the center console.

Modified Transmissions Developed for Hybrid Models

Mercedes-Benz has launched two advanced-technology hybrid models – the S400 HYBRID and the ML450 HYBRID – both powered by a combination of electric motors and an Atkinson-cycle version of the 3.5-liter V6. Both vehicles come with a modified automatic transmission that features one or two electric motors integrated within the transmission. Characterized as a “mild hybrid,” the S400 HYBRID has a single 20-horsepower electric motor inside the transmission. The ML450 HYBRID is considered a full hybrid, with two electric motors, each serving a specific purpose. Dedicated to pulling away under electric power, the motor on the output shaft of the ML450 HYBRID generates 80 hp and 192 lb.-ft of torque. Located closer to the gasoline engine, the other motor is set up specifically for acceleration and is rated at 83 hp and 173 lb.-ft of torque.

Award-Winning MCT Sports Transmission – The Best of Both Worlds

AMG is taking the automatic transmission another major step forward. With a start-up clutch that replaces the torque converter, the new seven-speed MCT sports transmission provides the direct feedback of a manual transmission with the total convenience of an automatic, offering impressive versatility and even faster shift times. Thanks to its low rotational mass, the start-up clutch helps the transmission respond instantaneously and dynamically, with no slip.

Standard equipment in the 2011-model E63 AMG sedan and SL63 AMG roadster, the MCT AMG SPEEDSHIFT PLUS transmission features seven speeds, four shift modes, an automatic rev-matching function and a Race Start mode. With four drive modes: “C” (Comfort), “S” (Sport), “S+” (Sport plus) and “M” (Manual), the MCT transmission provides customized shift control for maximum driving pleasure, and does so with no interruption of power.

In Comfort mode, smooth shifts coupled with a “soft” accelerator response are set up for smooth power transfer. In Sport mode, the engine and transmission interact quicker – upshifts and downshifts take place at higher engine speed. Gearshifts are around 20 percent faster than in Comfort mode. Switching to Sport Plus cuts another 20 percent off shift times, while the sportiest mode, Manual, reduces shifting times by another 10 percent – a total reduction of 50 percent compared with Comfort mode. In Manual mode, the gearshifts take only 100 milliseconds.

The rev-matching function provides precisely computerized matching of engine speed with every manual or automatic downshift, and is active in the “S” (Sport), “S+” (Sport plus) and “M” (Manual) modes. Not only does this smooth downshifting make driving more fun, but it also minimizes jerking, a special benefit when braking into a curve.

The E63 AMG sedan and the SL63 AMG roadster even come with a Race Start feature, which helps maintain full-throttle acceleration and optimal traction during race competition. After selecting the Race Start mode, the driver steps on the brake with the left foot and pushes the ESP Sport switch. When confirmation appears in the central display, the driver reconfirms Race Start by pulling the upshift paddle once, flooring the accelerator and releasing the brake. Engine speed is set automatically, and the car launches with full acceleration.

Seven Speeds – Smoother, Faster and More Frugal

In general, seven gear ratios provide a wider spread of ratios between first gear and top gear and, at the same time, allow the engine to run in its most favorable rev range more often. It also gives the electronic control unit more flexibility in terms of maximizing fuel economy and making the transmission’s reaction time extremely fast.

Unlike many transmissions, the seven-speed transmission will skip up to four gears if necessary when the driver downshifts, shifting directly from seventh to fifth, for example, or even sixth to second. This helps the transmission choose the right gear ratio for quick acceleration and ensure almost imperceptible shifts in the process.

Direct Select Shift Lever on Many Models

The seven-speed automatic also benefits from new “shift-by-wire” electronic control technology. The S- and E-Class sedans, CL coupe and the GL-, M- and R-Class sport utilities feature the Direct Select shift lever – a small stalk on the right side of the steering column.

Thanks to the latest electronic technology, Direct Select makes shift control simpler than ever. Lift the stalk up for reverse, push down for drive, and push a button on the end for park. Once underway, pushing either one of the shift buttons on the “back” of the steering wheel provides Touch Shift manual gear changes.

Though gears can be manually selected, computer control prevents downshifts that would cause the engine to over-rev. The system is user-friendly, not to mention providing a clean, open look to the center console.

Five-Speed Automatic Still State-of-the Art

Some AMG, 4MATIC and V12-powered models come with a driver-adaptive five-speed electronic automatic transmission as standard equipment. Both automatic transmissions feature adaptive electronic control and make use of a refined, proven hydrodynamic torque converter with a special lock-up clutch inside the converter for maximum fuel efficiency. The lockup clutch eliminates the usual torque converter “slippage,” providing the direct connection and fuel efficiency of a manual transmission when the lockup clutch is engaged. After starting out in first, the Mercedes-Benz lockup clutch engages in all gears. To put that into perspective, many cars lock up the transmission torque converter only in top gear.

Adaptive Electronic Wizardry

The heart of all Mercedes-Benz automatic transmissions is a high-performance micro-processor, which is designed so the transmission shifts as the driver expects and wishes it to react. Continuous electronic networking with the engine and chassis management systems allows the transmission computer to adapt to a wide variety of driving situations, and even to the driver’s style.

By comparing road speed changes and load, or throttle opening, the transmission computer can instantly discern uphill and downhill grades, and adjust shifting as a result. It delays upshifts on descents (for engine braking), as a driver is likely to do with a manual transmission. The micro-processor even considers cruise control and engine temperature in the shifting decision.

The computer also measures how fast the driver presses and releases the accelerator pedal. If the pedal is pressed relatively quickly, the transmission is more likely to downshift, for instance during sporty, more spirited driving, while upshifts are less likely when the pedal is released quickly. With normal pedal operation, shifts occur according to a basic program aimed at getting the best fuel mileage.

Smooth Shifts

The transmission computer is also networked to the ABS and traction control systems (and to yaw and steering sensors from the standard ESP stability control system) so that it can recognize cornering and low-traction conditions. Based on this data, the transmission may delay or hasten a gearshift to ensure that it creates no negative effect on vehicle stability or traction control. Not only does the transmission computer adjust shift feel according to engine speed and load (smooth shifts during leisurely driving, crisper shifting with more spirited driving), but it’s even able to reduce engine power for a split second (by retarding ignition timing) to ensure smooth gear changes.

AMG Paddle Shifters Inspired by Formula 1 Racing

Mercedes-Benz models produced by AMG, the company’s in-house high-performance division, are fitted with paddle shifters inspired by the world of Formula 1 racing. Mounted on the steering wheel, the paddle shifters work in conjunction with an AMG SPEEDSHIFT transmission to provide up to 35 percent faster gear changes than a conventional automatic.

Like all Mercedes automatics, SPEEDSHIFT will automatically downshift under heavy braking, selecting the optimal gear for the situation. Also, by holding the gear lever to the left, the transmission will choose the best possible gear for maximum acceleration in any situation. The AMG SPEEDSHIFT transmission will also hold a selected gear under high cornering loads, avoiding upshifts in mid-corner. As well, a special lightweight torque converter will lock up in all forward gears.

Shifting with Pleasure: The Six-Speed Manual

Mercedes-Benz offers a six-speed manual transmission for the C-Class sport sedans and SLK coupes/roadsters. The manual transmission offers extra driving fun for those who prefer a stick, as well as maximum control, with short gear lever throws for quick shifting. With an extra gear (as compared to a five-speed manual), Mercedes engineers narrowed the ratio gaps between each gear and made a slightly shorter first gear for quicker off-the-line acceleration, while maintaining an overdrive sixth gear for quiet and economical highway cruising. Shift effort is low, thanks to multiple-cone synchromesh, easing cross-gate shifts from second to third and from fourth to fifth. The reverse lockout is overcome by lifting the shift lever when selecting reverse.

Mercedes-Benz offers two innovative hybrid models for the 2011 model year – the S400 HYBRID premium luxury sedan and the ML450 HYBRID sport utility vehicle. Hybrid power is one of several fuel-efficient choices offered by Mercedes-Benz, the global leader in diesel passenger cars. In addition to an entire generation of super-clean, quiet BlueTEC diesel cars, Mercedes-Benz also leads the industry in development of fuel cell vehicles and offers cars powered by compressed natural gas in a number of global markets.

Characterized as a “mild hybrid,” the S400 HYBRID (335 total hp, 381 lb.-ft. of torque) comes with the world’s first lithium-ion battery designed specifically for automotive use. The light-weight, high-capacity lithium-ion battery powers a 20-horsepower electric motor, which works with a 275-hp V6 gasoline engine to provide impressive fuel economy.

On the SUV side of the Mercedes-Benz family, the ML450 HYBRID comes with two electric motors and a 275-hp V6 gasoline engine that work together to provide impressive hybrid power with fuel economy estimated at 21 miles per gallon around town and 24 mpg on the highway.

Hybrids Ideal For Atkinson-Cycle Engine

On both hybrids, Mercedes-Benz engineers optimized the 3.5-liter V6 engine for good fuel economy by taking advantage of the Atkinson principle. By delaying the closing of each intake valve, the intake stroke effectively becomes longer than the compression stroke, increasing thermal efficiency, which reduces fuel consumption and exhaust emissions.

Although Atkinson engines inherently produce less low-speed torque and throttle response, they are ideal for hybrid vehicles because the electric motor compensates for this disadvantage by working with the gasoline engine to provide excellent throttle response on acceleration. The Atkinson-cycle V6 has different cylinder heads, pistons and camshafts as well as modified variable valve timing control and a low-load oil pump for good fuel economy.

30 Percent Better Fuel Economy with S400 HYBRID

The Mercedes-Benz S400 HYBRID uses the V6 gasoline engine, a magneto-electric motor and sophisticated hybrid electronics to produce 30 percent better fuel economy than a comparable S550 model. Not only does the electric motor make 20 horsepower, but it also produces an impressive starting torque of 118 lb.-ft., while the gasoline engine develops 275 hp and 258 lb.-ft. of torque.

A powerful computer controls the hybrid system, recalculating the best operating mode 160 times a second. Capable of up to 50 million calculations per second, the system works to maintain an ideal balance between fuel economy and performance.

Light, Powerful Lithium-Ion Battery

The 120-volt lithium-ion battery weighs less than most other batteries and takes up less space, but has high energy density for its size. As a result, it can be installed in the engine compartment, so the car’s ample trunk capacity and spacious interior are not affected. The lithium-ion battery has a high-strength steel housing, a separate cooling circuit, and its cells sit in a special gel that dampens jolts and vibration.

Strong Electric Motor Provides Many Benefits

Characterized as a “mild hybrid,” the S400 HYBRID gasoline engine and electric motor work together for responsive performance, and its driveline includes a specially configured seven-speed automatic transmission, a transformer to power the 12-volt vehicle system and intelligent operating electronics. Acting both as the starter and generator, the disc-shaped electric motor is mounted in the torque converter housing, between the engine and transmission. A 120-volt, three-phase AC external-rotor magneto motor, its high torque is especially significant during acceleration, which is otherwise one of the highest fuel consumption modes. The electric motor also helps to dampen drivetrain noise and vibration, which means even better ride comfort.

The S400 HYBRID accelerates from zero to 60 miles per hour in 7.2 seconds and reaches an electronically limited top speed of 155 mph. Fuel economy is even better than an S-Class sedan powered only by a conventional V6 engine, and CO2 emissions are 21 percent lower.

A Fuel-Saving Start-Stop Feature

The hybrid system includes a fuel-saving start-stop feature that turns off the gasoline engine below nine mph when braking to a stop. When the S400 HYBRID is at a traffic light, for example, the gasoline engine is off, but the AC compressor and steering pump are operated electrically, so air conditioning and power steering are fully operational.

As soon as the driver releases the brakes or touches the gas pedal, the gasoline engine starts immediately, and works with the electric motor for good performance. Since the direct-drive electric motor operates at a much higher speed than a conventional geared starter motor, the engine starts instantly and imperceptibly, also avoiding the usually high exhaust emissions during a conventional starting mode.

It Even Recycles Energy

During braking, the electric motor acts as a generator, recovering kinetic energy and storing it in the lithium-ion battery. Under heavy braking, the vehicle’s conventional brakes also come into play. Recovered energy is stored in the battery and re-used whenever the electric motor is running.

During deceleration with no braking, the electric motor already acts as a generator, recovering energy and helping to slow the car. When the driver just touches the brake pedal, the generator output increases, which feels like heavier braking. Only when more brake pedal pressure is applied do the conventional wheel brakes come into action. These three stages are controlled seamlessly, so the driver perceives the system simply as smooth, responsive braking.

Cleverly Located Controls

Alternating current from the three-phase motor is converted into 120-volt direct current in a converter located where the starter motor used to go. Because the current flow sometimes measures as high as 150 amperes, the system is equipped with its own cooling circuit. A transformer in the right front wheel powers an on-board 12-volt system, which includes a conventional lead-acid battery in the trunk with convenient jump leads. Since most transmission oil pumps are engine-driven, an electric auxiliary oil pump ensures lubrication of the transmission in driving modes when the gasoline engine is off.

The S400 HYBRID has the same interior room, luxury and convenience features as other S-Class vehicles. The model is differentiated by unique seven-twin-spoke 18-inch wheels and HYBRID logos on the trunk lid and dash as well as BlueEfficency badging on the front fenders. A special hybrid pictogram within the speedometer shows the energy flow, energy recovery and battery charge.

The ML450 HYBRID Boasts 30 Percent Better Fuel Economy

Considered a “full hybrid,” the Mercedes-Benz ML450 HYBRID uses the V6 gasoline engine, two magneto-electric motors and sophisticated hybrid electronics to produce more than 30 percent better fuel economy than a comparable V8-powered ML550.

Integrated within the modified automatic transmission, each electric motor serves a specific purpose. Dedicated to pulling away under electric power, the motor on the transmission output shaft generates 80 hp and 192 lb.-ft of torque. Located closer to the gasoline engine, the other electric motor is set up specifically for acceleration and is rated at 83 hp and 173 lb.-ft of torque.

Working with both electric motors when full power is needed, the gasoline engine develops 275 hp and 258 lb.-ft. of torque. The electric motors are powered by a liquid-cooled, 288-volt nickel-metal-hydride battery that’s hidden under the rear cargo floor. A powerful computer controls the hybrid system, recalculating the best operating mode 160 times a second. Capable of up to 50 million calculations per second, the system works to maintain an ideal balance between fuel economy and performance.

During parking and low-speed operation, the ML450 HYBRID runs on the electric drive only. On hard acceleration, the gasoline engine is started automatically, and it works seamlessly with the two electric motors for surprisingly good performance. The hybrid system includes a convenient start-stop function that turns off the gasoline engine – for example, when coasting up to a red light – and re-starts it during acceleration.

When the ML450 HYBRID is at a traffic light, for example, the gasoline engine is off, but the AC compressor and steering pump are operated electrically, so air conditioning and power steering are fully operational. A Silent Start function provides noiseless starting of the gasoline engine.

During braking, the electric motor acts as a generator, slowing the SUV and recovering kinetic energy. Under heavy braking, the vehicle’s conventional brakes also come into play. Recovered energy is stored in the battery and re-used whenever the car runs only on the electric motors.

The ML450 HYBRID is differentiated by a HYBRID logo on the rear lift gate, a revised front hood with two power domes and unique five-twin-spoke 19-inch wheels. However, the HYBRID has the same interior room, convenience and safety features as other M-Class vehicles.

Daimler Trucks North America (DTNA) and Daimler Buses have once again received orders for low-emission vehicles. Thomas Built Buses, Daimler Trucks North America’s school bus manufacturer, has received an order for 130 compressed natural gas (CNG) school buses. That’s the biggest contract for natural gas buses in the company’s history. The buses were ordered by the Los Angeles Unified School District (LAUSD), and the vehicles are scheduled to be delivered in the fourth quarter of 2010.

The LAUSD transportation services division only accepts bids for buses operating on alternative fuels. The district currently operates the largest CNG bus fleet in California, with more than 300 natural gas buses. Thomas Built CNG’s produce emission levels that are close to zero. The buses have complied with the U.S. EPA 2010 emissions standards since 2007 and also meet the state’s tough California Air Resources Board (CARB) limits.

“We welcome this opportunity to demonstrate our commitment to environmental stewardship and enhanced passenger safety,” says Kelley Platt, President and CEO of Thomas Built Buses. “LAUSD underscores its commitment to sound environmental strategies with its selection of 130 additional school buses that incorporate clean-fuel technologies.”

Customer acceptance of buses with alternative drive systems is also demonstrated by the orders for Orion-brand hybrid and CNG buses. Daimler Buses North America has so far obtained more than 3,000 orders for Orion buses with hybrid systems, and it delivered 25 Orion VII CNG transit buses to four transit agencies in California last month.

Besides natural gas drives, DTNA is also using other alternative drive systems, including hybrid technology, in commercial vehicles. Last month, Daimler Trucks North America delivered four medium-duty Freightliner Business Class M2 106 Hybrid trucks to the city of Denver. These aerial bucket trucks will be used for forestry, traffic signal, and traffic sign repair.

In June, DTNA also announced the opening of the Local Hybrid Application Center at its Portland location. It will serve as a local competence center for the research and development of hybrid technology in North America and supplement Daimler Trucks’ Global Hybrid Center in Japan.

The new contracts are part of Daimler’s “Shaping Future Transportation” initiative for commercial vehicles. With this initiative, the company aims to use clean and efficient drive systems along with alternative fuels in order to realize the vision of zero-emission commercial vehicles that will satisfy tomorrow’s transportation needs. The initiative involves the sparing use of resources and the reduction of emissions of every kind, while guaranteeing maximum traffic safety.

Earlier this week, Tesla Motors CEO Elon Musk was in Detroit to accept the “2010 Automotive Executive of the Year Innovator Award”.  At the event, Musk laid out a timeline for his company, noting that Tesla will be supplying electric drivetrain technology for the Mercedes A-Class EV in the coming years.  The news isn’t surprising, considering Daimler purchased an 8 percent stake in Tesla last year (and already collaborates with Daimler on the smart ev); the real question is how long it will be before the A-Class EV will make it to the U.S.  We’ll keep you posted if we hear anything new; in the meantime, Wired has more details of Musk’s timeline covering Tesla’s other production targets.
