Daimler 360 GRAD - FAKTEN zur Nachhaltigkeit 2008 Daimler Nachhaltigkeitsbericht 2008 / Environmental protection, innovation, and safety / Innovation, development and safety / Sustainable mobility strategy for passenger cars / Model-specific hybrid modules* Model-specific hybrid modules* Automatic start-stop function. When the vehicle is not moving, the start-stop function automatically switches off the engine, thus avoiding unnecessary idling while the car is stationary. This not only results in substantial fuel savings in city driving but also reduces exhaust gas emissions and noise. In 2008, the belt-driven starter generator will initially be introduced in the A- and B-Class. The following models will be available from September 2008: � A 150 BlueEFFICIENCY � A 170 BlueEFFICIENCY � B 150 BlueEFFICIENCY � B 170 BlueEFFICIENCY Mild hybrids. Mild hybrids are equipped with a disc-shaped electric motor. Located between the engine and the transmission, the motor acts as a starter as well as a generator. The electric motor serves as a generator during braking and stores the recuperated energy in a compact lithium-ion battery. The convenient start-stop feature also reduces fuel consumption by using the electric motor to boost the engine when the vehicle begins to accelerate at low engine speeds. Purely electric driving is, however, not possible. The combination of an automatic start-stop feature, brake energy recovery, and a boost function will be introduced to the European market for the first time in mid-2009, in the Mercedes-Benz S 400 BlueHYBRID. Full hybrids (two-mode hybrids). The two-mode hybrid is equipped with an electronically controlled transmission that connects an internal combustion engine and two electric motors with the wheel drives. Power can be variably distributed between the engine and the electric motors, enabling purely electric driving as well. The system has two driving modes, one of which is optimized for city driving, while the other is geared toward longdistance traveling. In this way, the system maximizes the fuel savings potential. Daimler will be introducing the two-mode hybrid to the market in 2009, in the Mercedes-Benz ML 450 BlueHYBRID. BlueTEC HYBRID. A further hybrid option is one that combines the diesel exhaust treatment system BLUETEC with a hybrid drive. The specific advantages that diesel engines offer in terms of fuel economy make BLUETEC hybrids much more efficient than any gasoline hybrid developed to date. This combination will be used in the Mercedes-Benz C 300 BlueTEC HYBRID and the S 400 BlueTEC HYBRID, both of which are scheduled to commence series production in 2010. * Content on this page is available exclusively on the Internet.
