Mercedes-Benz prepares new V8 engines

In the years to come, the Sttutgart-based carmaker will consistently update its high-end engine range.


We are talking about new V8 units, with lower displacement, direct gasoline injection and twin-turbo technology. The new engines will work together with the 7G-TRONIC transmission and could also be fitted with the START/STOP system. Officials state that, by 2012, via the new technologies, the fuel consumption will be reduced by up to 30 percent, even on the AMG models.
