Once upon a time, the M156 was a signal of a new generation of Mercedes-AMG engines. This high-revving, naturally aspirated V8 featured 4-valve technology and generated 387 kW (525 HP) from 6,208 cubic centimeters of displacement. It was also the first engine to feature continuous cam phasing in each camshaft.
