Eight cylinders and a displacement of 6.3 litres in a front-mid-engine arrangement, a high-revving concept, dry sump lubrication and a performance-oriented intake and exhaust system: opening the almost two-metre long bonnet of the SLS AMG affords a view of an outstanding high-performance engine spefically developed by AMG for the new Gullwing model. With a peak output of 420 kW/571 hp at 6800 rpm and 650 newton metres of torque at 4750 rpm, the AMG 6.3-litre V8 unit sets new standards and is also the world’s most powerful naturally aspirated series production engine. The SLS accelerates from zero to 100 km/h in 3.8 seconds, and has a top speed of 317 km/h (electronically limited). The DIN kerb weight of 1620 kilograms produces an extremely favourable power-to-weight ratio of only 2.84 kilograms per hp.

The use of specific fuel economy measures has enabled a fuel consumption of 13.2 litres per 100 kilometres (NEDC combined) to be achieved. Power transfer in the SLSAMGis by a new, seven-speed AMGdouble-declutch transmission located at the rear axle in a transaxle arrangement. It is rigidly connected to the engine by a torque tube.

Based on the M156, which develops 386 kW/525 hp and 630 newton metres in e.g. the E 63 AMG, the new, naturally aspirated eight-cylinder engine is a comprehensive further development specifically for the SLS AMG. The most important modifications affect the intake and exhaust systems, the oil supply and the crankshaft drive. A total of more than 120 parts and components were redesigned on the basis of major findings obtained from more than 40 years of motor racing experience.

In design terms the M159 is a completely autonomous AMG development, as was the M156. This unique combination of a fast-running concept and a large displacement achieves the best of both worlds: exhilarating flexibility accompanied by high torque at low engine speeds. The new AMG V8 already delivers 545 newton metres to the crankshaft at 2500 rpm, with the maximum of 650 newton metres on tap from 4750 rpm – more than any other naturally aspirated engine in this output and displacement class. In short, the new AMG eight-cylinder guarantees dynamic acceleration, rapid intermediate sprints and sheer driving pleasure at the highest level, or relaxed, day-to-day cruising when preferred

Optimum cylinder charging thanks to newly designed intake air ducting

One key aspect of the increase in output and torque is the optimised cylinder charging. The new, more flow-efficient design of the intake air ducting leads to a reduction in pressure losses, while the completely revised valve drive improves the gas dynamics. The newly developed magnesium intake manifold features precisely coordinated resonance tube lengths. Eight velocity stacks with a length of 290 millimetres and a diameter of 51.5 millimetres supply the combustion chambers with fresh air. Behind the new air filters with a volume of just under 9500 cubic centimetres there are two throttle flaps with a diameter of 74 millimetres. Their electronic adjustment is practically instantaneous: it takes only 150 milliseconds to open the two throttle flaps to their maximum. The result is exhilarating responsiveness. Two hot-film air mass sensors located behind the air filters supply the engine electronics with the necessary temperature and density data for the intake air.

One special characteristic of the V8 engine is its sophisticated valve drive, which borrows features from the powerful AMGracing engines. The 32 valves in the cylinder heads are operated by bucket tappets. Their space-saving design allows a stiff valve train and therefore high engine speeds with large valve opening cross-sections, which in turn benefits output and torque. The large intake valves have a diameter of 40 millimetres, while their opposite numbers on the exhaust side measure 34 millimetres. In contrast to a racing engine, the valve drive is maintenance-free with hydraulic valve clearance compensation.

Four continuously variable overhead camshafts

All four overhead camshafts are continuously variable over a range of 42 degrees. Both the intake and exhaust camshafts are adjusted as a function of engine load and engine speed, ensuring extremely high output and torque values as well as smooth idling and especially low exhaust emissions. Depending on the engine speed, the valve overlap can be varied to ensure an optimal supply of fuel/air mixture to the combustion chambers and efficient venting of the exhaust gases. The variable camshaft adjustment is controlled electrohydraulically, and monitored by the engine control unit.

Distinctive exhaust note with two exhaust headers

Optimised performance and an emotional sound signature: these were the requirements when developing the sports exhaust system. Exhaust headers with precisely coordinated tube lengths – a further technology transfer from motor racing – ensure a significant increase in output and torque by improving the gas cycle. The large pipe cross-sections of the newly developed twin exhaust system effectively reduce the exhaust counterpressure. Two relatively small pre-silencers on the underbody and a large, transversely installed main silencer at the rear help to ensure optimum weight distribution.

The AMGspecialists attached particular importance to the sound signature of the large-displacement eight-cylinder power unit, and exhaustive tests were carried out to achieve a synthesis of immediately perceptible dynamism and the long-distance qualities typical of a Mercedes. Great attention was also paid to the elimination of irritating noises, while accentuating the frequencies perceived as pleasant and typical of a sports car. At the same time it was of course necessary to comply with the legal requirements – for example when measuring passing noise. The two exhaust tailpipes integrated into the rear apron emit a characteristic eight-cylinder sound that leaves the real car-lover in no doubt: here comes a true AMG.

Two ceramic catalytic converters optimised for counterpressure and located at the firewall directly by the exhaust header, plus two metal catalytic converters on the underbody, provide effective exhaust gas aftertreatment and ensure compliance with current and future limits such as EU 5, LEV 2 and ULEV. The new AMGengine also easily meets specific requirements for the US market, such as Onboard Diagnosis II and lambda sensor diagnosis.

Dry sump lubrication to lower the centre of gravity

One major criterion when formulating the technical concept for the SLS AMGwas the installed position of the engine. The requirement was for the engine to be positioned low down and well to the rear, so as to lower the car’s centre of gravity significantly and achieve a balanced weight distribution between the front and rear axles. The solution found, namely to install the eight-cylinder power unit as a front-mid-engine behind the front axle, combining it with a transmission in a transaxle layout, led to a weight distribution of 47 percent at the front and 53 percent at the rear which is typical of a sports car.

The low installed position of the V8 engine is the result of a changeover to dry sump lubrication – which eliminates the usual oil sump. The dry sump lubrication system of the M159 consists of a suction pump, a pressure pump and an external 5‑litre oil tank located in front of the engine. All in all, 13.5 litres of engine oil circulate around the complete system. The oil scavenging pump sucks the oil directly from the crankcase and cylinder heads, delivering it to the external oil tank at a maximum rate of 700 litres per minute. The efficient oil scavenging further improves the efficiency of an already very efficient engine.

The reciprocating pressure pump conveys the oil from the external oil tank back to the engine, ensuring effective lubrication even under the high lateral acceleration forces that usually occur on racetracks. The demand-related control of the oil pressure pump is based on the engine speeds programmed into the control unit, as well as the characteristic maps for temperature and engine load. This leads to a reduction in the engine’s power dissipation, and a considerable reduction in fuel consumption. Two large coolers in the front wheel arches, each with a blower fan integrated on one side, ensure that the engine oil is efficiently cooled.

Another innovation used in the engine of the SLS AMGfor the first time is the so-called “gas-spring principle”, where the air compressed beneath the piston as it moves down the gas-tight crank chamber is prevented from escaping. On the upstroke the rebound energy is almost completely returned to the pistons. This principle prevents flow losses. Another positive effect is the much greater rigidity of the crankcase. The gas-spring principle has enabled fuel consumption to be reduced by 1.5 percent – while increasing output by 7 kW/9.5 hp.

Outstanding strength and optimised lightweight construction also for the engine

As another new development, the eight forged pistons are a total of 0.5 kilograms lighter than cast pistons. The reduction in oscillating masses improves both responsiveness and flexibility. Optimum cooling of the severely stressed piston crowns is by means of pressure-controlled oil-spray nozzles in the crankcase. As another specific weight-saving measure, there are no steel liners locating the main crankshaft bearings. The crankcase of the M159 is wholly of aluminium, and around 4 kilograms lighter than its counterpart in the M156. To reduce weight even further, aluminium bolts are mainly used in the M159. This saves another 0.6 kilograms or so compared to steel bolts. The weight of the V8 engine in the SLS is 205 kg, producing a first-class power-to-weight ratio of 0.36 kg/hp.

As is usual in motor sports, the crankcase is a rigid bedplate design of closed-deck construction. The engine block and cylinder heads are of cast aluminium-silicon alloys (AlSi7 and AlSi17) which represent the state of the art in terms of weight, thermal and mechanical resistance and long-term strength. As in the M156, the engine specialists at Mercedes-AMGuse a particularly advanced process for the eight cylinder walls to produce a tribologically optimal surface, namely a coating applied by twin wire arc spraying (TWAS). The advantages of this technology patented by AMG are extremely low friction and wear accompanied by outstanding long-term durability. A considerably harder surface is achieved compared to conventionally coated cylinder walls. In fact the cylinder walls of the new AMGV8‑engine are twice as hard as conventional cast iron liners – a quantum leap for engine specialists.

Other high-tech components and systems adopted from the M156 include:

• the finely balanced crankshaft of forged steel;
• water-cooling of the cylinder head using the thermally very efficient crossflow principle familiar from the motor racing world;
• variable coolant control for optimised efficiency;
• computer-controlled fuel delivery, with the fuel integrated into the fuel tank.

Newly developed cooler module of weight-optimised design

The coolant is cooled by a large cooler module located behind the radiator grille. The condenser for the air conditioning and the cooler for the steering servo fluid are also integrated into this module. As a particular bonus, this completely new development has reduced the weight by around 4 kilograms compared to the previous components – while improving efficiency at the same time. A large suction fan located directly behind the radiator conducts the hot air away as required.

Efficient control unit for generator management

The Bosch ME 9.7 AMG control unit also has a generator management function as a further system that helps to save fuel. Sensors monitor the charge status of the vehicle battery, and reduce the output of the generator if the battery has sufficient charge. The system uses the overrun phases of the engine to recharge the battery, kinetic energy being converted into electrical energy by recuperation.

Careful combination of efficiency-enhancing measures has enabled an NEDC combined fuel consumption of 13.2 litres per 100 km (premium petrol) to be achieved. This is an outstanding figure, as the new SLS AMGis after all one of the most powerful cars in the super sports car segment.

Engine production at the Affalterbach plant

The new V8 powerpack for the SLS is produced in the ultra-modern AMG engine shop, on the “one man, one engine” principle. This means that a single technician assembles the engine by hand from start to finish – as witness the high-quality AMG engine plate bearing the signature of the technician responsible. The design of the AMG eight-cylinder is also a feast for the eyes, starting with the new, titanium grey cover of the magnesium intake manifold with its two prominent AMG logos, and the optional carbon-fibre engine compartment cover that frames the high-performance power unit so attractively.

AMG seven-speed double-declutch transmission with RACE START

The ideal partner for the powerful, naturally aspirated eight-cylinder engine is the AMG SPEEDSHIFT DCT 7-speed sports transmission – a newly developed double-declutch transmission with seven gears, four driving modes and a RACESTART function. The advantages of this technology, which is once again derived from motor racing, include highly responsive gearchanges without any interruption in tractive power, a tailor-made control strategy and improved gearshifting comfort. Specifically configured for the high-revving nature of the AMG 6.3-litre V8 engine, the AMGSPEEDSHIFT DCT 7-speed sports transmission provides optimum ratios with only small rpm changes. In short, the new transmission gives the driver even more dynamic acceleration for maximum driving pleasure.

AMG DRIVE UNIT with four driving modes for maximum pleasure

The central control point for the AMG SPEEDSHIFT DCT 7-speed sports transmission and all dynamic control functions is the AMG DRIVE UNIT. The rotary electronic control for selection of the four driving modes and activation of the RACE START function is located to the left of the E-SELECT shift lever.

The double-declutch transmission allows upshifts under full load both in automated and manual mode, where the gears can be shifted using the AMGshift paddles on the steering wheel. There is a choice of four driving modes for maximum driving pleasure and comfort: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) and “M” (Manual). In Controlled Efficiency mode the high torque already available at low engine speeds is used to shift up to the highest viable gear. The resulting dethrottling effect on the intake side lowers fuel consumption, with accompanying benefits in terms of engine noise. Controlled Efficiency also means comfortable gearchanges and “soft” accelerator characteristics for relaxed cruising.

In “S” mode the transmission remains in each gear to a higher speed, downshifts are faster and gearshifts are performed around 20 percent more rapidly than in “C” mode. Switching to “S+” mode shortens gearshift times by a further 20 percent, while “M” is the most sporty mode of all: the AMG 6.3-litre V8 engine now responds with even more “bite”, and the AMG double-declutch transmission changes the gears another 10 percent faster – a total reduction of 50 percent compared to “C” mode. In “M” mode the transmission performs gearchanges in less than 100 milliseconds. The upshift indicator integrated into the AMG instrument cluster informs the driver when a manual gearchange is advisable: seven LEDs coloured white, yellow and red indicate the necessary action. The faster the engine speed approaches the maximum of 7200 rpm, the more LEDs light up.

Best possible traction thanks to the RACE START function

The RACE START function delivers maximum dynamism: in order to use it, the driver has to activate the ESP® Sport function while the vehicle is at a standstill, and press the brake pedal with his left foot. Having preselected the RACE START program using the rotary switch, the driver is presented with a confirmation message in the AMG central display. After confirming the RACESTART function by pulling the “Up” shift paddle once, all he has to do is depress the accelerator fully and take his foot off the brake. The optimum start-up engine speed is set fully automatically, and the SLS AMGaccelerates away with flawless traction – all the way up to top speed if required. The driver does not need to shift the gears manually, as the DCT transmission performs lightning-fast gearchanges.

Automatic double-declutching function for even more emotional appeal

In the “S” (Sport), “S+” (Sport plus) and “M” (Manual) modes, the automatic double-declutching function is active. Every manual or automatic downshift is accompanied by precisely metered double-declutching – incrementally from “S” through “S+” to “M”. This not only adds to the driver’s emotional experience: the load-free downshift minimises load-change reactions, which pays dividends – particularly when braking into a bend on the racetrack – and also enhances safety in the wet or on ice.

The new AMGdouble-declutch transmission excels with compact dimensions and a low weight of only 136 kilograms, including the differential. Aluminium construction and the absence of a conventional torque converter improve efficiency and make a significant reduction in fuel consumption possible. A mechanical, multi-plate differential lock configured for sporty performance at the physical limits is also integrated into the transmission housing.

Torque tube with carbon-fibre drive shaft between the engine and transmission

The torque tube turns the AMGSPEEDSHIFT DCT 7-speed sports transmission and the V8 engine into a fixed unit. The engine and the transmission installed in a transaxle arrangement at the rear axle are firmly connected with very low flexural and torsional flexibility, and support each other. This has decisive advantages in terms of handling dynamics and driving comfort, as this sophisticated solution makes it possible to eliminate much more free play from the entire powertrain. The 1.64-metre long torque tube consists of a one-piece sand-cast aluminium housing, and weighs less than 25 kilograms. A drive shaft rotates at engine speed inside the housing. As in the Mercedes-Benz C-Class DTM racing touring cars, the shaft is made from carbon-fibre. One of the key advantages of this high-tech material is that despite its high strength, the shaft tips the scales at only 4.7 kilograms. This means that the 1.71-metre long drive shaft, which is required to transfer no less than 650 newton metres of torque from the engine to the double-declutch transmission, is around 30 percent lighter than a steel version would be.

A specially developed torsional damper is also active within the torque tube. This reliably eliminates resonances and vibrations, thereby optimising ride and noise comfort.

Gran Turismo 5 is unquestionably one of the most anticipated games for the Sony Playstation 3, and when the title makes its debut next spring, one of the vehicles featured will be the new Mercedes-Benz SLS AMG Gullwing.  To help highlight the game and the SLS’s debut in it, Mercedes has published some photos and a video showcasing what gamers can expect from both.

If the small sampling of photos we brought you yesterday highlighting the forthcoming Mercedes SLS AMG wasn’t enough to satisfy your desire to see the new Gullwing, today we can do you one better. Mercedes AMG has launched a webspecial for the model displaying the SLS AMG in all its unmasked glory, in vastly higher quality than the small pictures we brought you yesterday.

I won’t detail again the Mercedes SLS AMG’s various features, as you should already be familiar with them from our prior articles on the topic. I will, however, bring you the high resolution photos from the site, giving you a quick snapshot of what the webspecial offers.

When you’re finished browsing the photos below (be sure to click them to see the super sized version), head over to Mercedes AMG where you can check out the full Mercedes SLS AMG webspecial highlighting its performance specs, technology, interior and exterior, etc.

New details have emerged today of the forthcoming Mercedes-Benz SLS Gullwing:  according to AMG boss Volker Mornhinweg, the company is currently developing a plug-in electric version of the model.  The Mercedes SLS eDrive, as its being called, is expected to be offered with the same lightweight aluminum body as the standard SLS (a model that will see it debut in Frankfurt this September), along with an interior that again remains largely unchanged from the non-electric Gullwing.

According to Mornhinweg:  “The great thing is we haven’t had to alter the styling in any way,” who added “it’s completely original in appearance.”  Volker then went on to note that “The very nature of the SLS, with its sizeable engine bay, sturdy torque tube running back along the backbone of the car and the mounting point for fuel tank, lends itself perfectly to adaptation for electrification.”

In total, it’s being said the Mercedes SLS eDrive will boast 392kW and 649 lb-ft of torque – this compared to the standard SLS Gullwing’s 571 hp and 470 lb-ft.  While performance figures haven’t been finalized, the company is aiming for a 0-62mph time of less than 4 seconds (standard SLS:  3.8 seconds) and a top speed of 120mph (standard SLS:  196mph).  Range is between 93 and 112 miles, depending on the load placed on the battery, and the recharging time sits around five hours on high-density charge or eight hours on conventional power.

As for hardware changes, Mercedes engineers have taken the route of replacing the standard SLS’ double-wishbone suspension up front with a new pushrod front suspension – one that features coil-over dampers mounted horizontally – thus freeing up space around the front axle.  It is here that Mercedes will place two 98-kilowatt motors (there’s also two 98-kilowatt motors on the rear axle), making the SLS eDrive a four wheel drive vehicle.  Energy for these motors will be supplied via a lithium-ion battery, mounted in the space usually filled by the standard SLS’ torque tube.

Unfortunately, there is one caveat of the new Mercedes-Benz SLS eDrive:  if you’ve got your checkbook handy ready to be first in line to procure one, you’ve got a while to wait.  The SLS eDrive is tentatively set for production in 2015, so if you’re looking to fill an immediate need for an electric supercar, you’ll have to look elsewhere.  On a side note, there are rumors Audi could be debuting and electric R8 in Frankfurt…

We will of course keep you posted as new details of the Mercedes SLS eDrive become available.

In a brilliant marketing move – one that surely only the geniuses at their marketing department could have surmised –  Mercedes today has granted a bit of backstage access into the inner workings of their design department, revealing interior photos and design sketches of their forthcoming SLS AMG Gullwing model.  According to the company, “aviation engineering” was the inspiration for the SLS interior, as evidenced by “the centre console in the style of a jet’s operating console and the four striking air vents reminiscent of aircraft engines.”

According to Gordon Wagener, Head of Design at Mercedes-Benz: “The interior of the new Mercedes-Benz SLS AMG is not only very special because of the exclusive swing-wing doors. The visible influence of aviation engineering, the high-grade materials and the practicality typical of a sports car will make the hearts of sports car enthusiasts beat faster. At the same time the new interior styling indicates the design philosophy for coming generations of Mercedes sports cars.”

But why read about it when you can see it.

After releasing details of their new Mercedes-Benz SLS AMG Gullwing to select publications about a week-and-a-half ago, Mercedes AMG today has released a lengthy press release highlighting again the forthcoming model. Because we’ve already detailed the model once I’ll abstain from doing so again; however, I will let Daimler CEO Dieter Zetsche talk briefly about the new Gullwing. According to Dieter, “Mercedes-Benz is presenting an exhilarating super sports car in the guise of the new SLS AMG, which is bound to set the pulses of all car enthusiasts racing that extra bit faster. The SLS AMG is emotion pure and simple for the Mercedes-Benz brand and is set to become one of the most alluring sports cars of our era.”

Volker Mornhinweg, Chairman of Mercedes-AMG GmbH, adds: “Our customers will experience with the SLS AMG the expertise of our sports car manufacturer Mercedes-AMG, built up over 40 years of motor racing, along with the kind of scintillating design that only a top athlete from the Mercedes-Benz stable can offer.”

Remember, this is the first time in Mercedes AMG’s history that they’ve produced a vehicle entirely in-house. And while I’m certainly a fan of the work turned out by AMG, even coming close to creating a vehicle that can match the legendary status of the original Mercedes 300 SL Gullwing is certainly a tall order. Personally, I’d much rather opt for the original Gullwing over the reincarnated version regardless of what technology the SLS possesses, but that’s just me.

Time will tell how successful rekindling a legend will be, but in the meantime, keep scrolling for 50 or so photos highlighting the new Mercedes SLS AMG Gullwing along with the official press release detailing the model.

As the Geneva Motor Show gets set to open its doors to the press tomorrow, Mercedes has taken a moment to reveal details a model that won’t be in attendance – one that’s being officially called the Mercedes-Benz SLS AMG. Strangely enough, it sounds a little like a Cadillac model… oh wait, it is a Cadillac model. Nevertheless, that is the name of the vehicle that up until now has been known as the Mercedes SLC, or less formally, the new Mercedes Gullwing.

So what can we expect from the new Caddy Mercedes? Pretty much exactly what was already rumored to be in place. Power comes from a revised version of AMG’s 6.2-Liter V8, with output coming in at 563 hp at 6800 rpm and 479 lb-ft of torque at 4750 rpm. Revisions to the engine include a new magnesium intake with eight separate velocity stacks, two electronically controlled throttle plates to feed the new intake, a new dry-sump system to lubricate the engine, and a lowered position behind the front axle allowing a claimed 48 percent/52 percent front/rear weight distribution.

Also in place will be a new seven-speed transaxle gearbox, as opposed to the one currently utilized on the SL63 AMG. Mounted at the rear axle and encompassing the differential, the new gearbox is a dual-clutch automated manual transmission – one that that will shift gears by itself or at the driver’s command. Connecting the engine to the rear-mounted transaxle is a torque tube housing a lightweight carbon-fiber composite driveshaft, just one of the various components that help the SLS achieve a curb weight of 3,571 lbs (that’s nearly 300 lbs lighter than the SLR McLaren). The end result when mated with the AMG 6.3-Liter V8 is a 0-62 mph time of 3.8 seconds, while top speed comes in at 196 mph.

There’s no word yet on pricing for the model, although early reports indicate the Mercedes SLS AMG will likely be in the $250,000 range. We’ll keep you posted as new details are revealed; in the meantime, keep scrolling to see a few additional photos and diagrams outlining the Mercedes SLS AMG Gullwing (click any to enlarge), then head over to Car and Driver for their full report and photo gallery.

Despite the masking, this is by far the best look yet at what will be the new Mercedes Gullwing. Visible is a single louvre grille, reminiscent of the original 300SL Gullwing, as is a moveable spoiler in the rear. The overall contours of the model are also much more visible, due to the removal of the false body panels seen in the past.

According to AutoWeek, the new Mercedes Gullwing model – still yet to be named – is slated for a two-year production cycle of about 6,000 units, with pricing set to be “several hundred thousand dollars” (earlier reports indicated the model would be priced around $130,000). Power was originally thought to be supplied by AMG’s 6.3-Liter V8, but it’s now being speculated that the V12 from the SL65 AMG Black Series could be called on instead (which would obviously account for the price difference).

We’ll keep you posted as any new details of the Mercedes Gullwing are revealed; in the meantime, keep scrolling for a few additional photos (click to enlarge), then head over to AutoWeek for the full, action-packed gallery.
