Efficiency standards in the premium segment:
New V8 and V6 engines from Mercedes-Benz
The V8 is in a new league of its own

The new V8 engine.
On the basis of its predecessor, the new V8 has undergone concerted further development. For example, it has a 15-percent smaller displacement (4663 cc rather than 5461 cc) but generates 320 kW (435 hp) and therefore around 12 percent more output than the preceding unit (285 kW/388 hp). Time torque has been raised from 530 Nm to 700 Nm – an increase of 32 percent.

As the high maximum torque is already available from 1800 rpm, the new high-tech V8 already exhibits an outstanding power delivery at low engine speeds, together with smoothness and refinement that is remarkable even for an eight-cylinder. 
In the new V8, Mercedes-Benz engineers primarily achieved a high output for a lower displacement by using two turbochargers -- one for each bank of cylinders. The chargers were configured to provide high torque even at low engine speeds – compared to the previous engine the result is an increase of more than 40 percent at 2000 rpm. An outstanding 600 Nm is available between 1600 and 4750 rpm. The driver therefore perceives no turbo delay, but experiences the same pleasant and effortless performance from the new V8 as that delivered by a mighty, naturally aspirated 7-litre engine.
