Summary

With the new 6-cylinder engine, Mercedes-Benz has succeeded in implementing a design which, in addition to providing outstanding performance values along with the highest degree of comfort, also appropriately addresses environmental issues and economic viability. The new 60° V-angle and the extremely lightweight construction in the engine area provide an excellent degree of comfort. With third-generation direct injection (DEO3) in conjunction with multi-spark ignition, it was possible to develop new modes of operation thus opening up new areas of the characteristics map with fuel-optimised lean combustion. The brake specific fuel consumption values set new benchmarks for the combustion engine. Together with stop/start technology, shift point adjustment and the systematic reduction of rolling resistance, improvements in fuel consumption up to 20% are possible. All together, this engine design represents an outstanding engine line-up in all target vehicle model series from Mercedes-Benz. Sustainability for the future is also guaranteed through the advantageous injection technology and modularity.
