In 2012, Mercedes-Benz decided to turn the A-class from a high-roof hatchback (with a sandwich-floor layout designed for electrification) into a much lower, wider, and longer compact car with decidedly sporting aspirations. At the time, the move seemed slightly counterintuitive. But it has proved to be the correct decision: The current A-class has become a huge global success, it has spawned an entire family of models including the CLA and the GLA, and it has rejuvenated the brand’s image considerably among younger clientele.

2019 Mercedes-Benz A-Class

Now Mercedes is launching the second generation of “the new A-class,” which actually is the fourth generation overall. It is slightly bigger and even sportier than the outgoing model. And, for the first time, it will be offered in the United States as a four-door sedan—in addition to the CLA “four-door coupe.” We were offered the chance to drive the new A-class hatch in Europe, and even though this version won’t be sold in the U.S. (but it will be in Canada), it offers valuable insight into what we can expect once the sedan launches here.

Outside, the model has lost a bit of the predecessor’s cheekiness, and the new A-class looks a lot more serious. The aggressive upward kink on the flanks is gone, and the car now features a distinct wedge shape, with a front end that closely resembles that of the larger CLS.

Photos of the U.S.-market A-class sedan have not yet been released, but we can safely assume it will be visually aligned with the China-market A-class sedan, which was revealed there in April. That version has a slightly longer wheelbase than ours will, though.

While the A-class is pleasant to look at outside, it’s even better inside. The sporty, aggressively styled seats make a great first impression, but it is the dashboard that steals the show. Even low-spec models have two seven-inch TFT screens, with one in place of traditional gauges and one in the center of the dash. The cars we drove had the top-of-the-line configuration consisting of two 10.3-inch displays, which probably is the most futuristic-looking instrumentation currently available in a compact car.

Maybe even in any car, as Mercedes-Benz has brazenly decided to walk away from the usual top-down approach and has fitted its best and most recent infotainment system called MBUX in its entry-level offering. The A-class, in that way, beats the S-class.

One of the most novel elements is the way the driver can communicate with the car. Use the voice-recognition system (which can be activated by saying “Hey, Mercedes”) to make almost any car-related request, and the A-class has an informative answer—or a cheeky one. Try saying, “I love you,” or asking, “What do you think of BMW?” and you’ll get some interesting replies.

There is more, such as the backlit dashboard and air vents, which look as if they were taken straight out of an S-class coupe. And while other compact cars studiously avoid wood decor in order to not be seen as stodgy, the A-class can be specified with beautiful, opulent wood trim—at least in Europe—and it doesn’t look a bit old-fashioned.

“A is for Attack: the A-Class is a clear statement of the new dynamism of the Mercedes-Benz brand”, explains Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars. “It is completely new, down to the last detail. In automotive development, it’s not often you get the chance to start with a clean sheet of paper. Our engineers and designers have made the very most of that opportunity.”

Design and dynamism are obvious characteristics of the new A-Class even at first glance, simply in the way it sits up to 18 centimetres closer to the road than its predecessor. The radical new design idiom that was so enthusiastically received upon its first appearance with the “Concept A-CLASS” has been rigorously applied for the series-production model. With their fresh interpretation of the classic two-box design, the Mercedes designers have created an emotive exterior with a pronounced sporty flair. “Applying the new dynamic style of Mercedes-Benz to the compact class was a challenge that we thoroughly enjoyed”, explains Gorden Wagener, Head of Design at Mercedes-Benz. “The almost sculptural lines of the A-Class are very typical for Mercedes. The feature lines, particularly along the sides of the car, then give the A-Class structure and tautness.”

The objective when it came to the interior design was to complement the sporty look of the exterior. On top of this the car has a high-quality feel about it that is unique in this segment, achieved both through the design idiom as such and through the choice and combinations of the high-quality materials used. As seen in the Concept A-CLASS, there is an option allowing a smartphone to be fully integrated into the operating and display system. A special app makes it possible to use the full functionality of the iPhone® , and in due course also of other smartphones, in the car.

All trim surfaces feature an electroplated finish in “silver chrome”, giving them a genuine metallic surface with “cool touch” effect. “This is just one example of the way in which the quality of the A-Class’s interior is not defined by classic trim elements but by consistent design and by the specific materials used”, explains Hartmut Sinkwitz, Head of Interior Design. “The motto we used when designing the interior was ‘pure sportiness, newly interpreted’.”

Particular visual highlights include, for example, the air vents, which stand out like “sparkling jewels” (Sinkwitz), so underlining the exceptional quality of the interior. The sporty character of the vehicle is further emphasised by the integral seats (optional extra) in the front. The rear seat is similarly sporty in appearance and can accommodate up to three passengers.

As well as the basic specification, which can be individualised with a wide range of options, there is a choice of design and equipment lines that have been put together with the requirements of customers in mind: “Urban”, “Style” and “AMG Sport”.

The world premiere of the new A-Class (length/width/height: 4292/1780/ 1433 millimetres) will take place at the Geneva Motor Show (8 to 18 March 2012). It will be making its way to European dealers in September 2012.

Sporty exclusivity: the A-Class Sport offers a fresh definition of dynamism

For the first time, the performance specialists from AMG were involved in the development of the compact class from a very early stage. The result is the most dynamic version of the new model series – the A-Class Sport ‘engineered by AMG’, in which the visual affinity to the Concept A-CLASS is at its most evident – particularly in terms of the new diamond grille. The A-Class Sport features exclusive 18-inch AMG light-alloy wheels in a 5-spoke design with 235/40 R18 tyres all round and painted high-gloss black with a high-sheen finish, together with red-painted brake callipers. These give an indication

of the particularly dynamic driving qualities of the A 250 Sport and the A 220 CDI Sport, which are differentiated, amongst other factors, by a special AMG-developed front axle and a suspension that has been configured to match.

Hints of red on the AMG front and rear aprons also serve to emphasise the expressive positioning of the new model. The contrast between black trim and additional accents in red continues in the interior: the contrasting decorative topstitching on the steering wheel and seats is in this same bright shade, as are the seat belts. The ambient lighting of the instruments and the highlight rings of the air vents are similarly red.

Drive system: new petrol and diesel-powered engines

A broad range of both petrol and diesel engines has something to suit every performance requirement, whilst also demonstrating the current state of the art in terms of efficiency: for the first time, a Mercedes-Benz will produce emissions of just 99 g of CO2 per kilometre.

The bandwidth of the new generation of petrol engines with a displacement of 1.6 and 2.0 litres ranges from 90 kW (115 hp) in the A 180 and 115 kW (156 hp) in the A 200 through to 155 kW (211 hp) in the A 250. Common to all is the combination of direct injection and exhaust gas turbocharging, a more advanced combustion process and an extended stratification range for lean-burn operation that uses fast-acting injectors for the multiple injection of the fuel as well as on-demand multi-spark ignition. CAMTRONIC is an innovation that will be celebrating its world premiere in the 1.6-litre engine: adjusting the valve lift on the intake side restricts the amount of fresh mixture used in the partial load range, so reducing consumption.

The diesel engines also offer an impressively high level of efficiency and environmental compatibility, thanks to sophisticated injection technology and turbocharging. The A 180 CDI offers an output of 80 kW (109 hp) and a maximum torque of up to 250 Nm, while the A 200 CDI has a maximum output of 100 kW (136 hp) and torque that rises to 300 Nm. The A 220 CDI has a displacement of 2.2 litres, an output of 125 kW (170 hp) and torque of 350 Nm, delivering absolutely exceptional performance in the A-Class.

All engines in the new A-Class feature the ECO start/stop function as standard. The engines can be combined either with the new six-speed manual transmission or, as an option, with the 7G-DCT dual-clutch automatic transmission.

Further highlights: suspension, aerodynamics, safety

The dynamism promised by the design and drive system is realised by the suspension. A noticeably lower centre of gravity and a new 4-link rear axle provide the basis for this; and would also make the installation of 4MATIC all-wheel drive possible. Customers can choose between various suspension settings, among them the optional sports suspension with Direct-Steer system. The electromechanical steering in the A-Class has been completely redesigned, so that the electric motor for the power assistance now sits directly on the steering gear in the form of a compact and extremely precise Dual Pinion EPS.

Its exceptional aerodynamic performance, with a new record Cd value of 0.26, puts the A-Class at the top of its class. This is further helped by the standard roof spoiler, which hides all the unsightly aerials on the A-Class.

The A-Class is the only vehicle in its class to feature as standard a radar-based collision warning system with adaptive Brake Assist, which lowers the risk of rear-end collisions. The COLLISION PREVENTION ASSIST system gives a

visual and acoustic warning to alert a possibly distracted driver to identified obstacles, and prepares Brake Assist for the most precise braking response possible. This is initiated as soon as the driver steps firmly on the brake pedal.

The PRE-SAFE® preventive occupant protection system is now available for the first time in the A-Class. This innovation, which was premiered in the S-Class in 2002, thus makes its very first appearance in the compact class. Core features of PRE-SAFE® are reversible belt tensioning, the closing of side windows and sliding sunroof in case of critical lateral dynamics and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems. PRE-SAFE® is always activated in response to critical longitudinal and lateral dynamics and may also be triggered upon intervention by certain assistance functions.

The democratisation of safety also encompasses an array of other assistance systems which have been adopted into the A-Class from the larger model series. These include:

• ATTENTION ASSIST (standard)
• Brake HOLD function (standard)
• Hill-Start Assist (standard)
• DISTRONIC PLUS
• Adaptive Highbeam Assistd
• Blind Spot Assist and Lane Keeping Assist
• Speed Limit Assist (speed limit sign recognition)
• Active Parking Assist
• LINGUATRONIC
• Reversing camera

Downsizing for the entry-level engines and downspeeding for the more powerful units – that is the Mercedes-Benz strategy for the diesel engines in the new A-Class. The wide range meets every performance requirement, and demonstrates the potential residing in the diesel engine: for the first time – with the A 180 CDI – a Mercedes-Benz will emit just 98 g of CO2 per kilometre. As a further highlight, the A 220 CDI already meets the Euro-6 emission standard only coming into effect from 2015.

The diesel engines also boast extreme efficiency and environmental friendliness, thanks to state-of-the-art injection technology and turbocharging. The A 180 CDI kicks off at 80 kW (109 hp) and offers maximum torque of up to 250 Nm (dual clutch transmission) or 260 Nm (6-speed manual transmission). In the A 200 CDI the maximum power output stands at 100 kW (136 hp), accompanied by maximum torque of 300 Nm. The A 220 CDI has a displacement of 2.2 litres and generates 125 kW (170 hp) with 350 Nm of torque, giving the performance of the A-Class a decidedly sporty touch.

From the S-Class to the A-Class: the diesel engines of the OM 651 series

Since its world premiere in 2008 the direct-injection diesel engine known as the OM 651 has been setting standards in terms of performance and torque characteristics, economy, emissions and smooth running. It is in more widespread use than any other Mercedes-Benz diesel engine and serves as a model of efficiency and power right up to the S-Class. For transverse installation the belt drive for the ancillary units, the installed position of the turbocharger and the air ducting have been modified.

No less than three versions are used in the new A-Class:

• Dynamic to drive, extremely efficient and outstandingly clean, the A 220 CDI is only available in combination with the 7G-DCT dual clutch transmission. The 125 kW (170 hp) top diesel is equipped with a weight-optimised crankshaft with individual bearing covers bolted from below and four counterweights, enabling it to tip the scales at around six kilograms less than a longitudinally installed OM 651 of the same displacement. The single-stage turbocharger has larger dimensions than that in the 80 and 100 kW variants. The A 200 CDI has multiple exhaust gas recirculation (see “Under the microscope”) to reduce nitrogen oxide emissions. It already meets the Euro-6 emission standard coming into force from 2015. With 112 g of CO2 per kilometre (provisional figure) the A 220 CDI sets new standards in its segment. With a displacement of 2.2 litres the engine is comparatively large, and therefore already agile at low rpm. “Downspeeding” is the term used by the engine specialists at Mercedes-Benz to describe this combination of a large displacement and low engine speeds. As a result it has been possible to make the ECONOMY mode of the 7G-DCT transmission decidedly economical and comfortable. If the driver selects “S”, gearshifts are performed much faster and the ratio spread uses the rpm reserves of the engine for dynamic performance.The performance of the A 220 CDI – which is available in BlueEFFICIENCY and Sport versions – is at sports car level with 7.8 seconds from zero to 100 km/h and a top speed of 227 km/h.

• The 1.8-litre engine variant is used in the A 180 CDI with the 7G-DCT dual clutch transmission and the A 200 CDI. The displacement was reduced by shortening the stroke (83 mm instead of 99 mm). The significantly longer connecting rods ensure lower transverse friction, and the two Lanchester balancer shafts are also of low-friction design. The single-stage turbocharger was optimised for efficiency and features adjustable vanes. With a distance between cylinders of 94 millimetres and cylindrical gears driving the camshafts, transverse installation and the necessary length restriction were part of the design specification from the very start.

To realise the start/stop function, the belt drive is decoupled from the crankshaft in all three engines.

Other common features include:

• Common rail technology with a rail pressure increased to 1800 bar. The maximum ignition pressure of 180 bar also contributes to the high power output and a muscular torque curve.
• The oil injection nozzles and the water pump are activated only when required, in order to save energy and fuel. The controlled oil pump additionally reduces oil flow and thus fuel consumption.
• The engine block is made of cast iron, the cylinder head of aluminium.
• A two-piece water jacket in the cylinder head provides for optimum cooling in the area of the combustion chamber plate. This enables an ignition pressure of 200 bar and a high specific power output.
• The cast iron barrels have undergone considerably finer honing than on the predecessor, also contributing to the reduction in fuel consumption.
• To compensate for the second-order forces which are inherent to four-cylinder in-line engines there are two Lanchester balancer shafts at the bottom of the engine block running in low-friction roller bearings rather than conventional plain bearings.
• The two-mass flywheel has been specifically designed for high engine torque at low engine speeds in order to isolate the crankshaft’s vibration stimuli, thereby contributing to the engine’s excellent smooth running.

Replete with Mercedes-Benz know-how: the OM 607

For the A 180 CDI with manual transmission Mercedes-Benz has had recourse to its cooperation with Renault to achieve fuel economy advantages from a compact, lightweight, low-friction engine which has been rigorously downsized. The common-rail four-cylinder with a rail pressure of 1600 bar is currently in its sixth generation, with more than 1.3 million units produced each year. This 1.5-litre engine with low-pressure EGR generates 80 kW (109 hp). With 98 g of CO2 per kilometre, it is among the most environmentally friendly diesels in the compact car segment. The turbocharger features variable turbine geometry (VTG).

This engine with the in-house designation OM 607 weighs around 30 kilograms less than an OM 651. Numerous components are specific to Mercedes-Benz, for example the OM 607 has the engine mountings of the M 270 petrol engine, as well as a special two-mass flywheel. The starter flanged onto the transmission, the alternator and the refrigerant compressor also come from the Mercedes modular system, and are driven by a belt with six grooves.

Like all Mercedes engines, the OM 607 was required to absolve the extensive engine test programme involving bench-testing and endurance runs. The application effort devoted to the OM 607 by Mercedes-Benz was very considerable. In a joint project team of Mercedes and Renault personnel the engine was especially improved with respect to NVH and driveability. Coordination work also went into the ECO start/stop function included as standard. This Mercedes-specific feature also operates at temperatures down to minus 10 degrees Celsius, for example, and can therefore make a more frequent contribution to fuel economy.

Mercedes-Benz is calling it the pulse of a new generation, Auto Motor & Sport said “A” for all perfectly done”,”A” as in “all different”, Focus said, “Top-class, this “A” (Bild), “A” as in “all new” (Der Spiegel), “Muscular, low, sporty” (AutoBild), and the list could go on. So what is it about the new Mercedes-Benz A-Class that has everyone raving?

Standing as much as 7 inches lower on the street than the previous A-Class model, the new 2012 A-Class communicates a passion for design at the very first glance. This radical form language, presented and enthusiastically acclaimed around the world with the Concept A-CLASS, was consistently implemented in the series production car. The appearance of the new A-Class reflects this new Mercedes-Benz design strategy. The result is what is known as a two-box design with a distinct character of its own, a sportily emotive exterior and an exceptionally high-quality feel to the interior.

“Translating the new dynamic style of Mercedes-Benz into the compact class was a challenge that was great fun to tackle”, explains Gorden Wagener, Head of Design at Mercedes-Benz. “No other car in this segment is as progressive as the A-Class. Absolutely typical for Mercedes is the sculptural shape of the A-Class. The character lines, in particular on its sides, lend the A-Class structure and terseness. The new dynamic style is perceptible at first glance in the interior as well.”

Defined edges and tautly drawn surfaces mark out the exterior design of the new A-Class. The constant interplay between concave and convex surfaces creates a characteristic play of light, particularly along the sides of the car, which contributes to its unique appearance.

Typical features of the long, sporty front are its pronounced V-shape, the separate headlamps, the radiator grille with central Mercedes star and double slats to either side of the star, as well as the additional air intakes on the sides. The “dropping line” apparent in the side profile dissipates towards the vehicle’s front end. The design of the headlamps, together with the configuration of the light functions within them, is a key element of the design concept.

The light modules and LEDs behind the headlamp cover glass have been arranged in such a way as to create the characteristic “flare effect” for the daytime running lamps and indicators. The so-called “flare” is made up of the feature line within the headlamp, the LED modules for the daytime running lamps and the bulb sets for the indicators. This signature effect gives the car its energetic look and so helps to define a new, youthful face for Mercedes.

The perfect interplay of dynamic design and excellent aerodynamics is nowhere more apparent than in the roof, with its smooth surfaces and taut, arcing curve. The silhouette reveals smooth, flowing lines finishing in a flat edge. The roof spoiler, which conveniently hides all the aerials, provides an extra sporty touch and gives structure to the roof assembly. The beltline rises to the rear to form a pronounced wedge-shape. The side view is distinguished by sensuously moulded sculptural side panels and crisp lines. The front structural edge, above the wing, falls in what is known as a “dropping line” in a gentle arc towards the rear. The powerfully-shaped shoulder muscles above the rear axle serve to emphasise the car’s coupé-like character. A further line sweeps up from just in front of the rear wheel arch, then gently fades away. All these lines give depth and dynamism to the car’s profile. Dynamic side sill panels provide a final finishing touch towards the bottom of the car, enhancing the appearance of elegant light-footedness.

The broad emphasis of the tail end is revealed in an interplay of convex-concave surfaces and edges. The tail lights continue the line of the muscular shoulders back towards the rear, while their horizontal orientation emphasises the car’s powerful breadth. The light functions are provided by fibre-optic cables and LED modules. Here, too, the interaction between design and aerodynamics is very clear: the surface finish of the tail lights is not only an interesting design feature, but also improves the airflow around the vehicle thanks to defined airflow break-away edges in the rear section.

At the center of Mercedes-Benz’s presence at the Geneva Motor Show, running March 8 to 18, 2012, will be the world premiere of the new 2012 A-Class. Mercedes is opening up a whole new chapter in the compact segment: markedly emotive in design, with engines ranging from 80 kW (109 hp) to 155 kW (211 hp), and extremely efficient, with emissions from just 99 g/CO2/km. At the same time the new model reminds us that Mercedes-Benz safety in design is not a question of price – the standard specification includes, amongst other things, the radar-based COLLISION PREVENTION ASSIST system.

“A is for Attack: the A-Class is a clear statement of the new dynamism of the Mercedes-Benz brand”, explains Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars. “It is completely new, down to the last detail.

The result is the most dynamic version of the new model series – the A-Class Sport ‘engineered by AMG’, in which the visual affinity to the Concept A-CLASS is at its most evident – particularly in terms of the new diamond grille. The A-Class Sport features exclusive 18-inch AMG light-alloy wheels in a 5-spoke design with 235/40 R18 tyres all round and painted high-gloss black with a high-sheen finish, together with red-painted brake callipers. These give an indication of the particularly dynamic driving qualities of the A 250 Sport and the

A 220 CDI Sport, which are differentiated, amongst other factors, by a special AMG-developed front axle and a suspension that has been configured to match.

Hints of red on the AMG front and rear aprons also serve to emphasise the expressive positioning of the new model. The contrast between black trim and additional accents in red continues in the interior: the contrasting decorative topstitching on the steering wheel and seats is in this same bright shade, as are the seat belts. The ambient lighting of the instruments and the highlight rings of the air vents are similarly red.

The official photos of the 2012 Mercedes-Benz A-Class have hit the web slightly ahead of schedule and thanks to Belgian website Autofans, we can show them to you. We have been covering spy photos of the A-Class for some time now, so we are happy to report that the final production car looks as good as we were hoping.  Part of its good looks are due in part to the C-pillars curvature which gives it a more coupe like back.

In an interest of getting the photos out to you as quickly as possible, I will save the full article with complete details for later.

Mercedes-Benz released the first teaser video of the 2012 A-Class today, ahead of its world debut at the Geneva Motor Show.

The Mercedes A-Class is entirely wrapped in QR coded camouflage.  The A-Class prototype will be just one of many models making their way  through Germany as part of a contest. One winner will receive  a trip to the car’s unveiling in Switzerland at the Geneva Motor Show. To enter into the contest, people will download the “A-Class QR-Trophy” app from the Apple App Store or Android Market. Once installed, users can then collect badges by scanning QR codes from prototypes, Facebook and Twitter. In total, four different badges will be available and each of them will give you a single entry into the contest.

The 2012 Mercedes-Benz A-Class will be built on the new MFA platform which is also what the B-Class rides on. It is likely that, like the platform, engine options will also carryover from its big brother.  If this is the case, we can expect five petrols with outputs ranging from 109 PS (80 kW / 108 hp) to 204 PS (150 kW / 201 hp). There will also then be four diesels with 122 PS (90 kW / 120 hp) to 204 PS (150 kW / 201 hp).

In 1993 Mercedes-Benz ventured into a completely new vehicle class with the revolutionary Vision A93 concept. The Concept A-Class signals the beginning of a new generation of smaller vehicles with expressive design. Celebrating its premiere at the New York and Shanghai Auto Shows, technical highlights of the Concept A-Class include front-wheel drive, a new turbocharged four-cylinder gasoline engine developing 210 hp, a dual clutch transmission and a radar-based collision warning system with adaptive Brake Assist.

The Concept A-Class features a long hood, low silhouette, slim side windows and a sophisticated interplay between lines and surfaces. “The Concept A-Class introduces the new Mercedes-Benz design idiom into the premium small car segment in a sculptured, light and expressive interpretation,” says Professor Gorden Wagener, Head of Design at Mercedes-Benz. “We use the term ‘captured energy’ to express the sheer dynamism exuded by the Concept A-Class. Our formal sources of inspiration were the wind and waves, as well as aviation engineering, resulting in this “cool” look.”

New turbocharged gasoline engine, seven-speed dual clutch transmission

The front-wheel drive Concept A-Class ushers in a new premium small car era at Mercedes-Benz and includes a four-cylinder gasoline engine from the new M270 series. The engine was designed for transverse installation and thanks to direct injection and turbocharging offers high performance together with minimal emissions and fuel consumption. Other highlights of the all-aluminum engine include injection pressures of up to 2,900 psi and fast-acting piezo injectors.

The Concept A-Class is equipped with the two-liter variant of the new engine, developing 210 hp. This BlueEFFICIENCY engine is combined with the new Mercedes-Benz dual clutch transmission which has a three-shaft setup with seven forward gears. The transmission shifts automatically with no interruption in tractive power and therefore is more economical, sporty and comfortable.

Exterior design with defined edges and a free interplay of surfaces

One major characteristic of the new design idiom at Mercedes-Benz is the expressive interplay between lines and surfaces – which the designers refer to as a “clean” concept. Thanks to concave and convex surfaces with the resulting light modulation, this creates a unique sculpture-like presence. The Concept A-Class reinforces this theme of defined edges and interacting surfaces, which Mercedes- Benz first showed in the F800 Style. The side view is highlighted by three prominent lines: the front structural edge forms a dropping line towards the rear, while the pronounced shoulder muscle over the rear axle emphasizes the car’s coupelike character. A further line extends upwards in front of the rear wheel arch in a sweeping curve. These lines lend more depth and character to the side profile. The door handles are recessed into the doors and emerge electrically at the touch of a button.

The unusual wing-like structure of the exterior mirrors is suggestive of flow and lightness. Another prominent feature is the open side skirt, which creates an unique light-and-shadow effect. Reminiscent of a turbine rotor, the large 20-inch wheels reinforce the impression that the Concept A-Class has been shaped by the wind.

The front end of the Concept A-Class catches the eye with the Mercedes-Benz emblem surrounded by a star-filled sky. Where there are usually openings or louvers, the radiator grille consists of numerous metallic silver “dots” on black stems. This theme is reflected in the design of the wheels.

The wide rear end exudes power and athleticism, and is enlivened by an interplay between convex/concave surfaces and pronounced edges. The tail lights continue the lines of the muscular shoulders towards the rear, emphasizing the car’s width with their horizontal orientation. The aerodynamic spoiler lip in the tail lights improves efficiency while the diffuser creates a downforce to aid handling.

Interior dominated by designs from aviation engineering

The interior of the Concept A-Class, which is flooded with light from the large panorama roof, appears to be from another planet. Many of the unusual features were inspired by aircraft engineering and reflect ideas from the “Mercedes-Benz Aesthetics No. 2” interior sculpture. Various component groups have been reduced to a minimum, for example the dashboard and center console are merely brushed aluminum structures. The result is a transparent, open, bionic design.

The eye-catching dashboard of the Concept A-Class takes the form of an aircraft wing and has a translucent, stretchable cloth covering. Thanks to this sophisticated fabric, which is vapor-coated with chrome particles, the bionic cellular structure of the dashboard remains visible – its design is reminiscent of a canvascovered aircraft wing with underlying struts. Dramatic backlighting highlights the futuristic instrument cluster which appears to float in space thanks to the translucent dashboard and lack of a conventional support structure. Its lines continue into the door paneling like vapor trails from the wings of a jet.

The air vents in the dashboard are inspired by the engines of a jet aircraft and the translucent backlit vents change color depending on the temperature the passengers have selected for the climate control system – they are blue if cool and red when the heat is on. The prominent gauges in the instrument cluster were inspired by the afterburner of a jet engine and are lit in red. The center console is designed as a high-tech flight control panel with a gear selector in the shape of a “thrust control” lever. With their molded-over head restraints and pronounced lateral support the seats are reminiscent of a pilot seat in a jet fighter.

Titanium and silver tones are combined with a light, elegant beige in the interior. Magenta is used to produce highlights that contrast with the car’s alubeam silver paint finish, which follows the dramatic contours of the exterior like liquid silver.

The Concept A-Class makes use of modern materials such as the high-tech covering on the dashboard, high-grade nubuk leather and metallic-finished leather, which is created by dying semi-aniline with metallic pigments followed by embossing. This links the 125-year tradition of the Mercedes-Benz brand and its future innovation.

COMAND Online with revolutionary graphic design offers ease of use for smartphone applications

A smartphone is fully integrated into the infotainment systems of the Concept AClass. When the phone is inserted into the recess provided in the center console, it is automatically synchronized with the COMAND multimedia system and all the functions of the smartphone, including internet radio, email and social networks such as Twitter or Facebook, are shown as applications on the 7-inch display and operated by the rotary/push control.

The visual presentation of the screen elements is unique with a deep, threedimensional look created by laser-like magenta-colored lines. This nearproduction display was created by designers and engineers at the Mercedes-Benz development laboratory in Palo Alto, California. The menus in the Concept AClass are in both English and Mandarin.

Headlamps with optical fibers produce a unique effect

A very special lighting effect is created by the headlamps of the Concept A-Class, as the innovative full-LED high-performance lights incorporate the starry sky motif of the radiator grille with numerous light points. The daytime running lamps are made of 90 optical fibers with aluminum sleeves and are arranged in a wingshape within the headlamp. The tentacle-like fibers form individual, diffused light sources to create a dramatic contrast between soft and bright.

The LED indicators appear to float freely within the headlamps like an enclosed air bubble in a perfume bottle and create a unique effect from any angle. The indicators are mounted in six chambers at the top of the headlamp and their vaporcoated reflectors remain invisible.

Familiar from the 2012MY CLS-Class, the LED high-performance headlamps of the Concept A-Class combine active lighting functions with LED technology. The projection module of these LED headlamps is no longer round but flatter and more aggressive. This distinct design is reinforced by the matte carbon-fiber housing, which contrasts with the aluminum surround of the projection module.

Optical fibers with aluminum sleeves are also used in the tail lights, using 120 fibers in the C-shaped tail light clusters to create a unique visual effect with their subtle glow. When braking, the continuous light band between the two tail lights also illuminates to make the Concept A-Class appear even wider. The turn signals are self-contained elements within the center of the tail lights. The housing of the tail light is made of carbon-fiber with the numerous red elements providing visual depth.

New assistance and braking system reduces the risk of rear-end collisions

Safety pioneer Mercedes-Benz is showing yet another milestone in automotive safety technology in the Concept A-Class – a radar-based collision warning system with adaptive Brake Assist – a world first in the premium small car segment. This system gives a visual and acoustic warning to an inattentive driver and primes Brake Assist for a precise braking response as soon as the driver presses the brake pedal.

In contrast to other systems available in this class, the new Brake Assist Collision Prevention Assist is not merely an urban driving system designed to minimize the effects of minor collisions. Instead this innovative solution provides protection against typical rear-end collisions in all driving situations and Mercedes- Benz expects the new safety system to greatly improve accident statistics. Following detailed analyses of accident data, Mercedes-Benz safety specialists estimate that this radar-based technology can help to prevent around 20 percent of all rearend collisions, and mitigate the severity of a further 25 percent.

As the world waits for the new versions of Mercedes’ A-Class and B-Class model ranges, Automobile magazine has published renderings of both models, demonstrating what they believe the two models will look like.

For the A-Class rendering, the model is virtually identical to the earlier leaked patent images, which should show precisely what the forthcoming model will look like.  As for the B-Class, it draws heavily from the A-Class, with the main differences the front apron and overall proportions.

The new Mercedes-Benz B-Class will celebrate its premier at the International Auto Show (IAA) in Frankfurt this September, with the new model hitting European dealerships in November.
