Article by Christian Andrei, on January 10, 2012

The two hybrid E-Class models from Mercedes-Benz are greatly anticipated so when the Mercedes-Benz E300 BlueTEC Hybrid and the E400 Hybrid made their debut at the 2012 Detroit Auto Show, the news generated plenty of interest. Mercedes-Benz has also now released more details.

Powering the Mercedes-Benz E300 BlueTEC Hybrid is a 4-cylinder diesel engine, which has an output of 150 kW (204 hp) combined with an electric motor, which delivers 20 kW and 250 Nm. It is claimed that the E300 BlueTEC Hybrid has a fuel consumption rating of 4.2 l/100 km. The U.S. market won’t get this model.

Instead, the E400 Hybrid will be sold in U.S., as well as in China and Japan. A V6-cylinder petrol engine, which has an output of 225 kW (306 hp) and 370 Nm, is powering this model.

When combined with an electric motor, it can produce 20 kW and 250 Nm. When based on the American CAFE standards, the consumption figures are City 24 mpg, Highway 31 mpg, Combined 27 mpg. Professor Dr. Thomas Weber, Daimler Board Member for Group Research and Head of Mercedes-Benz Cars Development, said that these E-Class models will enable them to continue with their “comprehensive hybrid offensive.”

He added that this modular technology represents a fast method for its other model series to be complemented with hybrid ones. He said that by focusing on the various needs of worldwide markets, the company can offer exactly what its customers desire.

The fuel consumption of the E-Class hybrids is very low but they offer an excellent driving experience. He said that these two models stand for hybrid motoring at the premium level.

Whether it’s for a long journey or a short trip, Mercedes-Benz E300 BlueTEC HYBRID is a perfect efficient vehicle, with the added benefits of spaciousness, comfort and safety.

As a hybrid unit, this vehicle provides practical and frugal driving in the city and is suited for stop and go traffic. Its four-cylinder diesel engine, meanwhile, allows for fuel-efficient drive over long trips. Basically, the Mercedes-Benz E300 BlueTEC HYBRID employs a 150-kW (204 hp) 2.2-liter four-cylinder diesel engine and a dynamic hybrid module.

To ensure dynamic acceleration, the E300 BlueTEC HYBRID makes use of the 20-kW electric motor that is sandwiched between the diesel engine and the seven-speed automatic gearbox. This electric motor could be used as alternator mode to recuperate braking energy. In addition, this electric motor allows the E300 BlueTEC HYBRID to operate in electric-only mode.

Derived from Mercedes’ modular hybrid principle, E300 BlueTEC HYBRID consumes just 4.2 liters of fuel per 100 kilometers and emits 109 grams of carbon dioxide per kilometer. The intelligent modular hybrid system – along with the 7G-TRONIC, a wet start-up clutch and the lithium-ion battery – eats up little space while weighing just around 100 kg.

In addition, the hybrid components of the E300 BlueTEC HYBRID boast of all the attributes of the extensive "seven-stage safety concept." Interestingly, the new Mercedes E300 BlueTEC HYBRID is expected be granted an ISO TR 14062 environmental certificate by the time it is introduced into the market.

This certification augments Mercedes’ commitment to comprehensive environmental protection, as enshrined in Daimler group’s operating guidelines. This means that Mercedes considers the environmental effects of a vehicle throughout its lifecycle.
