Mercedes-Benz is setting previously unachievable efficiency standards in the premium segment with completely newly developed V6 and V8 engines. The new V8 engine has a displacement of 4663 cc and develops a maximum power output of 320 kW (435 hp), which is around 12 percent more than its predecessor despite approximately 800cc lesser in displacement. Torque has increased from 530 Nm to 700 Nm – i.e. by no less than 32 percent. Fuel consumption has however been reduced by 22 percent.
With the same 3499 cc displacement as its predecessor, the new V6 engine develops 225 kW (306 hp). Torque has increased from 350 Nm to 370 Nm. Here too, the improvement in fuel efficiency is remarkable. The S 350 with the new V6 engine consumes an economical 7.6 litres per 100 kilometres, a saving of 24 percent compared to its predecessor.
Mercedes-Benz has achieved this considerable leap in efficiency with the use of a start/stop function as standard and other features such as newly developed, third-generation direct petrol injection with spray-guided combustion, multiple injection and multi-spark ignition. With this new generation of V-engines, Mercedes-Benz is clearly demonstrating that with concerted further development, internal combustion engines still have a great deal of potential, and that V6 and V8 engines with their great running refinement can continue to be used to good effect in the future.
