Mecedes-Benz to Rolls Out Europe's First Diesel Hybrid

The E 300 BlueTEC HYBRID consumes 4.1 litres of fuel per 100 kilometres (57.3 mpg).

Published: 08-Mar-2010

With the E 300 BlueTEC HYBRID being presented at the Geneva Motor Show, Mercedes-Benz is offering a look ahead to Western Europe's first diesel hybrid. It pairs a 2.2-litre four-cylinder diesel engine developing 150 kW (204 hp) with a powerful hybrid module. Its 15 kW electric motor, positioned between the internal combustion engine and the 7-speed automatic transmission, assists the diesel engine when the car is accelerating (boost effect) and is used for the recuperation of braking energy in alternator mode, although it is also suitable for driving using electric power alone. Based on the innovative modular system for hybrid vehicles developed by Mercedes-Benz, the diesel hybrid ushers in a new era of hybrid drives. The E 300 BlueTEC HYBRID consumes 4.1 litres of fuel per 100 kilometres (CO2 109 g/km). It will be launched at the end of 2011.

The technical basis for the E 300 BlueTEC HYBRID is the E 250 CDI with a four cylinder diesel engine developing 150 kW (204 hp). For the new hybrid model, the Mercedes-Benz engineers have used the fuel-efficient 4-cylinder diesel engine in combination with a compact electric motor developing 15 kW. The electric motor draws its energy from a high-voltage, lithium-ion battery, which has already proven itself in the S 400 Hybrid. Despite the high overall output of up to 165 kW (224 hp) and a torque of over 580 Nm, the E 300 BlueTEC HYBRID consumes no more than 4.1 litres of fuel per 100 km (NEDC), equivalent to CO2 emissions of 109 g/km. Fuel consumption is therefore on a par with extremely efficient small cars, while the hybrid drive system outperforms current six cylinder diesel engines in terms of output and driving enjoyment.

The E300 BlueTEC Hybrid offers all the driving characteristics of a full hybrid, such as purely electric driving, stop/start function, recuperation, boost effect and, for the first time, "sailing" and silent starting of the internal combustion engine by the high-voltage electric motor.
