With the new V8 diesel engine of the E420 CDI, Mercedes-Benz is introducing an engine that is a balanced, powerful overall motor. Its consistent optimizations and excellent specific values reached in its class, more than make up for its lower displacement of 4.0 l, compared with its competitors. It will be offered exclusively as the Euro 4 model with a particulate filter. Starting with the E-Class, this engine, a basic though enhanced development of the familiar V8 diesel engine, will replace its predecessors in the S-Class, as well as in the M-Class and G-Class. The production location at Motorenwerk Berlin was kept.
