Auto Car | Mercedes-Benz S-Class | The compact hybrid module combines the hybrid functions of an automatic start-stop system and energy recuperation. In all, this means that the S 400 HYBRID sets a new standard in its class, making it the world's most economical luxury saloon with a petrol engine.
The excellent fuel consumption and the low CO2 emissions of the S 400 HYBRID are accompanied by truly superior performance potential: the modified 3.5 litre petrol engine generates 205 kW/279 hp, while the electric motor produces 15 kW/20 hp and starting torque of 160 Nm.
The Mercedes-Benz S 400 HYBRID is based on the S 350, and features an extensively modified drive train. This encompasses a further development of the 3.5-litre V6 petrol engine, an additional magneto-electric motor, the 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary power and control electronics, the voltage converter and the high-voltage lithium-ion battery.
During braking the electric motor acts as a generator, and is able to recover kinetic energy by a process known as recuperation. During this process the electric motor works together sensitively with the engine brake of the internal combustion engine and the conventional wheel brakes. The recuperated energy is stored by a compact but efficient lithium-ion battery in the engine compartment, and retrieved when required. Major advantages over conventional nickel/metal hydride batteries include a higher energy density and greater electrical efficiency combined with more compact dimensions and a low battery weight. Thanks to space-saving installation in the engine compartment, the boot capacity and generous interior dimensions remain unchanged. The hybrid module also has a convenient start-stop function.
Apart from the trailblazing hybrid of the S 400 HYBRID, the range of engines for the 2009 S-Class comprises eight other powerful units: two diesel variants and six petrol engines with six, eight and twelve cylinders. Detailed fine-tuning of these engines has been supplemented with addition fuel economy measures as part of the BlueEFFICIENCY package. These include aerodynamic optimisation, demand-controlled fuel pumps and the fuel-efficient gearshift programme for the standard 7G-TRONIC automatic transmission. These measures have enabled Mercedes-Benz developers to reduce fuel consumption and CO2 emissions by up to seven percent compared to the preceding models. By means of additional well-aimed aerodynamic measures, the Mercedes-Benz engineers have also managed to reduce wind noise, thus further enhancing the standard of ride comfort.
With diesel fuel consumption of 7.6 litres per 100 kilometres and CO2 emissions of 199-201 grams per kilometre, the S 350 CDI BlueEFFICIENCY (173 kW/ 235 hp) likewise boasts outstanding figures for the luxury class. Mercedes-Benz achieves this exemplary efficiency with a tailor-made BlueEFFICIENCY package, which also includes closed underbody panelling and decoupling of the 7G‑TRONIC automatic transmission at standstill.
The 3.0 litre diesel engine is also used in the S 350 CDI 4MATIC. The
second diesel variant is the eight-cylinder S 450 CDI(235 kW/320 hp) with a displacement of 4.0 litres. The range of petrol engines comprises the six-cylinder S 350/ S 350 4MATIC (200 kW/272 hp) with a displacement of 3.5 litres and the two eight-cylinder units in the S 450/S 450 4MATIC (250 kW/340 hp; displacement 4.7 litres) and S 500/S 500 4MATIC (285 kW/388 hp; displacement 5.5 litres). The flagship model is still the S 600 with the 380 kW/517 hp twelve-cylinder biturbo unit (displacement 5.5 litres), which accelerates the luxury saloon to 100 km/h in 4.6 seconds. The Mercedes-AMG high-performance contributions to the range are the S 63 AMG with its 386 kW/525 hp V8 engine (displacement 6.2 litres) and the S 65 AMGwith a 450 kW/612 hp twelve-cylinder engine (displacement 6.0 litres).
A world-first combination of state-of-the-art assistance and protection systems is available for the 2009 S-Class. Many of these systems are also available in the new E-Class, which has been on the market since the end of March. The new assistance systems turn the models of the E- and S-Class into "intelligent" partners for their drivers. The car is able to "see", "feel", to respond "instinctively" to detected dangers and to act "on its own initiative" in order to avoid accidents or to reduce the severity of accidents.
"Similarly to the established Mercedes inventions ABS, ESP®, Brake Assist and PRE-SAFE®, the new assistance systems are also geared to the realities of how accidents occur and what consequences they entail," observes Dr. Thomas Weber, member of the board of management at Daimler AG and responsible for corporate research and the development of Mercedes-Benz Cars. "The aim in developing these systems was to prevent particularly common and serious collisions. With this concept, the S-Class not only protects its own occupants but also plays a key role in enhancing safety for other motorists," Dr. Weber adds.
To this end, Mercedes-Benz also deploys cameras which scan the road far ahead of the vehicle, monitor the surrounding area and interpret typical critical situations. Such cameras are employed in the optionally available Adaptive Highbeam Assist system, for example. This system detects vehicles with their lights on which are travelling towards or ahead of the car in which the system is fitted and controls the headlamps such as to ensure the largest possible range without dazzling other drivers.
The Sindelfingen-based engineers have also enhanced Night View Assist, which is now equipped with a special pedestrian detection function: as soon as the system detects pedestrians ahead of the car, they are highlighted on the display to make them more readily noticeable.
Lane Keeping Assist is another system that "looks ahead" for even safer driving. The system's computer is able to recognise lane markings by evaluating the contrasting images of the road surface and the markings. If the vehicle leaves the lane identified by the Assist function unintentionally, the driver is warned by short vibrations of the steering wheel. Unlike conventional systems of this kind, the Mercedes system is able to evaluate the driver's activities as well, and can reliably ascertain whether the car is leaving its lane intentionally or not. There is therefore no warning if the driver accelerates before overtaking or joining a motorway, brakes heavily or enters a bend, for example.
The images supplied by the windscreen camera are also used by the new, optional Speed Limit Assist system, which identifies speed limit signs in passing and shows the relevant speed limit in the central display (standard for S 600).
