“The A-Class makes a clear statement on the new dynamism of Mercedes-Benz”, said Dr. Dieter Zetsche, CEO of Daimler AG and Head of Mercedes-Benz Cars. “Together with the successful new B-Class and three further model variants based on this vehicle architecture, it will be an important driver in our ‘Mercedes-Benz 2020’ growth strategy. We are expecting a conquest rate of more than 50 percent for the A-Class. And that’s why we say that ‘A’ now stands for attack.”
Representatives of the international press were able to gain a first impression of the new A-Class on the eve of the Geneva Motor Show. Dr. Dieter Zetsche unveiled the Mercedes athlete in the compact segment as part of an exclusive presentation. The “first pulse of a new generation” was experienced live by an audience that included Germany’s national soccer coach Joachim Löw and team manager Oliver Bierhoff, as well as national players Benedikt Höwedes and Mario Götze.
The new A-Class exudes dynamism from the very first glance – its sits lower to the ground than its predecessor by up to 18 centimetres. The radical design language that was introduced with the “Concept A-CLASS” to an enthusiastic reception worldwide has been systematically carried over into series production. With a reinterpretation of the classic two-box design, Mercedes-Benz designers created an emotional exterior with an extremely sporty character. And with a cd figure starting from 0.26, the A-Class sets a new benchmark in its class.
Premium interior and full iPhone® integration
The sporty appearance continues into the interior. Added to that is a premium feel that is unique in this vehicle segment. The operating concept also sets benchmarks with a fully integrated smartphone. The driver now has access to the main content of his iPhone® with the “Drive Kit Plus for the iPhone®” and an app concept developed in-house by Daimler that brings “Digital DriveStyle” into the vehicle. This enables the full range of smartphone capabilities to be used safely and conveniently inside the car, too, for the first time.
All functions of the iPhone® integration can be used with the Audio 20 entry device, and will also be available for a wide range of other Mercedes-Benz models as of this summer. Furthermore, Mercedes-Benz will shortly be enabling the in-car use of smartphones with other operating systems.
New petrol and diesel engines with exemplary efficiency
A wide range of spark-ignition and diesel engines fulfils every performance desire and, at the same time, marks the current state-of-the-art in efficiency – for the first time, a Mercedes-Benz with an internal combustion engine will emit just 99 g CO2 per kilometre. The output spectrum ranges from 80 kW (109 hp) for the entry-level diesel through to 155 kW (211 hp) for the new 2.0-litre petrol version. Mercedes-Benz is introducing an innovation in the 1.6-litre petrol engine in the shape of CAMTRONIC – by adjusting valve lift on the inlet side, the volume of fresh air is restricted under partial load and fuel consumption reduced. All six engines are equipped as standard with direct injection and the ECO start/stop function. As an option, they can be combined with the 7G-DCT dual-clutch automatic.
The new A-Class – exemplary in dynamics and safety
At the same time, the A-Class provides impressive proof that safety is not a question of price at Mercedes-Benz – the radar-based COLLISION PREVENTION ASSIST system and ATTENTION ASSIST are part of the standard equipment. Well-known safety features from the larger Mercedes model ranges are also available for the A-Class for the first time, including PRE-SAFE® and DISTRONIC PLUS, as well as the blind spot, lane keeping and speed limit assistants. The sophisticated chassis design chassis design guarantees high active safety and previously unheard-of handling characteristics. The most dynamic version in the lineup is the A-Class Sport engineered by AMG, on which the visual relationship to the Concept A-CLASS is particularly evident thanks to the new diamond grille.
E 300 BlueTEC HYBRID – the world’s most fuel efficient full-size car
With the E-Class diesel hybrid, Mercedes-Benz is starting a new chapter in the brand’s core segment and setting benchmarks for full-size business vehicles along the way. The S 300 BlueTEC HYBRID, which is available as both a saloon and estate, sets new records in efficiency. The world’s most fuel-efficient full-size model sets the pace with outstanding efficiency figures (4.2 l/100 km) combined with high power output. The four-cylinder diesel in the E 300 BlueTEC HYBRID generates 150 kW (204 hp) and 500 Nm of torque. The electric motor delivers 20 kW and 250 Nm.
“Our modular hybrid drive reduces consumption and increases driving fun and comfort at the same time,” said Prof. Dr. Thomas Weber, Daimler Board Member for Group Research and Head of Mercedes-Benz Cars Development. “Plus, the system is so compact that is fits entirely into the engine compartment, complete with the battery. This means that there are no reductions in available space, neither in the interior nor the boot.” Mercedes-Benz is the only premium manufacturer to offer an estate with hybrid drive – the load-master among hybrids.
World premiere for a top-class athlete – the new SL 63 AMG
With a power output ranging from 395 kW (537 hp) to 415 kW (564 hp), the new Mercedes-Benz SL 63 AMG offers the perfect pre-requisites for unparalleled dynamics and a uniquely refined driving experience. Systematic lightweight design sets the new generation of the high-performance roadster – and the entire new SL line-up – apart. Thanks to an all-aluminium body-in-white and carbon-fibre rear lid, the weight of the SL 63 AMG is down by 125 kilograms. A performance boost is delivered by the combination of a further refined AMG sports suspension based on Active Body Control, new AMG speed-sensitive sports steering, AMG high-performance composite
brake system and AMG SPEEDSHIFT MCT 7-speed sports transmission.
“Typically for AMG, we have once again loaded the top version of the SL with a few more horses, forming the basis for its supreme dynamics,” said Dr. Joachim Schmidt, Executive Vice President Mercedes-Benz Cars, Sales and Marketing. “At the same time, the performance specialists in Affalterbach have also achieved an impressive improvement in efficiency. The new SL 63 AMG boasts average fuel consumption of just 9.9 litres per 100 kilometres, 4.2 litres less than its predecessor.” This means that the reduction in fuel consumption for the AMG version matches that of the series-production model at around 30 percent.
Efficient driving fun as standard – more new models for the C and E-Class
Alongside the E 300 BlueTEC HYBRID, Mercedes-Benz is adding two more efficiency champions to its C and E-Class lineup. Among the most fuel-efficient cars in its class is the E 220 CDI BlueEFFICIENCY Edition, which will reach dealers in March. Thanks to the Aerodynamics package, electric power steering (EPS) and a longer rear axle ratio, the 125 kW (170 hp) full-size model consumes just 4.5 litres of diesel per 100 km. This equates to CO2 emissions of 119 g/km – ten grammes or almost 8 percent less than before. Arriving on the market in parallel is the C 180 BlueEFFICIENCY as the new entry-level petrol C-Class. The 115 kW (156 hp) 1.6-litre turbocharged four-cylinder consumes just 5.8 l/100 km. The CO2 figure of 136 g/km marks an improvement of up to 21 g/km (ca. -1.0 l/100 km) compared with the previous C 180 with similar equipment.
C-Class Sport – the C-Class has never been so dynamic
With the new Coupe models “sport – engineered by AMG”, as well as the AMG Plus sports package, the selection of sporty C-Class versions is greater than it has ever been. The new coupe models C 250 Sport and C 250 CDI Sport are exceptionally dynamic, with specialists from AMG involved in their development. Both models offer the visually upgraded AMG Plus sports package, the more direct speed-sensitive steering and sporty transmission settings in S and M mode (in combination with 7-speed automatic). The new models will be available on the market starting June 2012.

The new E 300 BlueTEC HYBRID is all set for its market launch with record efficiency values of 4.2 l diesel/100 km and 109 g CO2/km, accompanied by increased torque and power output. Its modular hybrid concept with lithium-ion battery does not impose any compromises on space and offers an impressive driving experience thanks to start/stop, recuperation, boost effect, all-electric driving and sailing. The new model is available as a saloon and an estate. The E 300 BlueTEC HYBRID is the world's most fuel-efficient model in the luxury segment.
Mercedes-Benz is opening a new chapter in its brand's core segment and at the same time setting new standards for luxury-class business vehicles: the E 300 BlueTEC HYBRID, which is available as a saloon and an estate, boasts truly impressive performance. The 4-cylinder diesel engine of the E 300 BlueTEC HYBRID is rated at 150 kW (204 hp) and 500 Nm. The diesel engine combines with an electric motor rated at 20 kW and 250 Nm to produce a harmonious overall concept.
"The E 300 BlueTEC HYBRID represents the continuation of our comprehensive hybrid offensive. The modular technology paves the way for us to quickly introduce hybrid models to complement other model series," explains Professor Thomas Weber, Daimler Board Member for Group Research and Head of Mercedes-Benz Cars Development. "By clearly focussing on the different requirements of the global markets, we are able to offer precisely the models that our customers want."
The new model does not force passengers to compromise in terms of spaciousness, either in the interior or in the luggage compartment. The intelligent, modular hybrid concept represents a comprehensive enhancement of the S 400 HYBRID – the clear market leader in its segment: no body modifications are necessary, the hybrid module is flexible and also suitable for deployment in other model series. All this comes at only a moderate price increase of € 3570. In Germany the E 300 BlueTEC HYBRID costs € 51,794.75 as a saloon, while the estate model retails at € 55,007.75 (in each case incl. 19% VAT). Both models are to be launched in June 2012.
The philosophy: enhanced efficiency without compromising on comfort or benefits
The E 300 BlueTEC HYBRID forms part of the brand's intelligent downsizing strategy, which involves making conventional models far more efficient than previously – without sacrificing driveability or comfort.Here the in-house engineers have their sights set on exemplary consumption figures in everyday traffic rather than on standard or NEDC combined consumption, for instance. The familiar "Real Life Safety" philosophy, which focuses on safety benefits under real-life conditions rather than standardised crash-test results, is augmented by "Real Life Efficiency".
The E 300 BlueTEC HYBRID is based on the notoriously economical E 250 CDI, yet has a higher output and 15 percent lower fuel consumption.Overview of the E 300 BlueTEC HYBRID:
On the road, therefore, the E 300 BlueTEC HYBRID is easily a match for the E 300 CDI (170 kW/540 Nm), yet it boasts around 35-percent lower fuel consumption and CO2 emissions.In terms of vehicle weight, too, the E 300 BlueTEC HYBRID is on a par with the E 300 CDI.
At the same time, hybridisation enhances ride comfort:the car starts and moves off in virtual silence, while the hybrid module also damps any internal combustion engine vibrations. What's more, complete climate control is available even in start/stop mode.
Coasting along the motorway
Mercedes-Benz hybrid technology offers a wealth of extra functions that enhance both comfort and efficiency as well as helping to deliver a special driving experience underpinned by accomplished sportiness:
- When the car is stationary - ECO start/stop: the internal combustion engine switches off when coasting at speeds up to 160 km/h, since ancillaries such as the steering, brakes and refrigerant compressor operate electrically. It is restarted quickly, smoothly and virtually silently.
- Manoeuvring: in most cases, the car uses electric power alone for manoeuvring and parking.
- Accelerating: electrical power alone is used for moving off and driving under low load. Acceleration from standstill is particularly powerful, since the electric motor's full torque of up to 250 Nm is available instantaneously.
- Boost function: the electric motor supports the combustion engine during acceleration, e.g. in the course of overtaking.
- Cruising: when the car is being driven at a constant speed, the engine control unit shifts the operating points towards exceptionally low specific fuel consumption levels.
- Sailing "sailing", as it has come to be known, is possible at speeds below 160 km/h. The combustion engine shuts down and the desired speed is maintained by the electric‑motor alone until the battery needs recharging.
- Kinetic energy recuperation when coasting or braking: when the car is coasting (decelerating), the electric motor acts as a generator. When the brake pedal is pressed, the generator output is initially increased proportionally for greater deceleration. Only when increased brake pressure is applied are the wheel brakes additionally deployed.
- Information: an additional savings effect arises after a relatively short period of time, as drivers come to apply the above-stated functions in an increasingly more purposeful and effective manner. They are supported here by the display concept in the hybrid models – the central display provides information on the current energy flow and the charge status of the battery.
The hybrid module: a compact and intelligently integrated powerhouse
The hybrid drive unit is a further development of the module from the S 400 HYBRID and is based on the 7G-TRONIC PLUS automatic transmission.Distinguishing features include the omission of the hydraulic torque converter and the addition of a wet clutch of the kind also found in the high-performance AMG models. Consequently, the electric motor can be integrated in the transmission unit in such a way that it takes up only marginally more space than the 7G-TRONIC (+65 mm). The omission of the converter allows all-electric motoring as well as "sailing", thus significantly boosting the potential to reduce fuel consumption.
The compact electric motor, which is installed in space-saving configuration in the clutch housing between engine and transmission, is a 3‑phase AC internal rotor magneto motor which generates a maximum output of 20 kW and peak torque of 250 Newton metres at an operating voltage of 120 volts.
The components: perfectly integrated into the vehicle
The hybrid drive's electrical energy is provided by the high-voltage lithium-ion battery specially developed for use in vehicles.Its key characteristics include an output of 19 kW and an energy content of 0.8 kWh, allowing the E-Class to run on electric power alone at up to 35 km/h and for up to one kilometre. Space-saving installation of the drive in the engine compartment in place of the conventional starter battery means that the generous interior dimensions and the luggage compartment capacity remain unchanged. In addition to serving as an energy accumulator for the electric motor, the lithium-ion battery is also connected via the voltage converter to the 12V on-board electrical system, which supplies power to standard power-consuming devices such as the headlamps and the comfort features.
Sophisticated packaging means that numerous hybrid-specific components such as the high-performance electronics in the engine compartment can be integrated directly with the internal combustion engine, thus neatly rounding off the modularity concept:the hybrid models can be produced on the same assembly line as their conventional counterparts without needing to be diverted elsewhere. Another advantage of the overall concept is the scalability and compatibility with other vehicles and engines.
Safety: on a par with previous models
Intelligent integration of the hybrid systems without the need for changes to the body has the practical benefit of not restricting spaciousness in any way as well as ensuring that all hybrid models boast exactly the same high level of safety as their counterparts with an internal combustion engine – a very important aspect for Mercedes-Benz. Accident behaviour has been successfully tested crash simulations and tests.
