The reign of the naturally aspirated big-block Mercedes V8 is coming to a dramatic end, with the revelation that all eight-cylinder Benz units will be turbocharged by the 2011 model year, including AMGs.

An entirely new family of engines will begin to flow out of Stuttgart in 12 months time with a new emphasis on direct injection and turbocharging to improve power, efficiency and CO2 reductions.

Daimler and Mercedes-Benz R&D board member, Dr Thomas Weber, said the new “MoVe” (Modular V6 and V8s) engines will first be seen in the completely new CLS, the refreshed R-Class people mover and CL coupe’s replacement, the S-Class coupe.

A naturally aspirated 3.5-litre V6, a twin-turbo V6 and smaller-displacement twin-turbo V8 are all in the mix towards the high-performance end of the range.

Direct injection will be incorporated in all engines and the majority will be designed with the capability of integrating with hybrid systems.

At the AMG factory, the current 6.2-litre naturally aspirated V8 will also be replaced by a 5.5-litre direct injection twin-turbo V8.

Further range evolutions will occur in 2011 with the updated C-Class coupe, all-new SLK roadster and ML-Class SUV, and a diesel hybrid “Bluetec” version of the E-Class.

A fully redesigned SL roadster is due for 2012 and will take full advantage of Mercedes’ new power-boosting, fuel-saving, emissions-reducing engine technology.
