Efficiency standards in the premium segment:
New V8 and V6 engines from Mercedes-Benz
The V6 particularly impresses with its low fuel consumption

The new V6 engine. |
The new V6 engine is naturally aspirated, and has the potential for future use of a turbocharger thanks to the modular design concept. The most striking change between the new V6 unit and its predecessor is a reduction in the V-angle between the cylinder banks from 90 degrees to 60 degrees. This enabled the balancer shaft countering primary vibrations to be omitted, and as a result the driver registers an outstanding level of comfort.
A completely new intake and exhaust gas system with a variable-resonance intake manifold and optimised airflows was also developed for the new V6. This enabled the output of the 3499 cc engine to be increased to 225 kW (306 hp) (Previous engine of the same displacement in the S-Class: 200 kW/272 hp). Torque has increased from 350 Nm to 370 Nm, and is available between 3500 and 5250 rpm.
