Mercedes-Benz is set to launch a completely new diesel engine generation starting in the autumn of 2008. For its world premiere, the Stuttgart-based car manufacturer will unveil a C-Class model with this new four-cylinder engine. In the C 250 CDI BlueEFFICIENCY Prime Edition, this engine produces, with its 2.2 litres of displacement, 150 kW / 204 hp and 500 Nm of torque. The premiere model can accelerate from a standstill to 100 km/h in just 7.0 seconds, on the way to its top speed of 250 km/h. Notwithstanding these exceptional performance figures, the Prime Edition only consumes an average of 5.2 litres of fuel per 100 km (NEDC), with CO2 emissions of 138 g/km. The engine impresses with its eager responsiveness and smoothness of operation, which can make it a sensible alternative to the higher-displacement six-cylinder engines in future.
