3.0L Turbo I6 Mild-Hybrid
The M256 marks Mercedes' return to the straight-six — silky and refined, with an electric auxiliary compressor and 48-volt mild-hybrid that banish turbo lag for instant, seamless thrust.
Mercedes abandoned inline-sixes for V6s in the 1990s, then revived the layout in 2017 because the straight-six's natural balance suited electrification — the belt-driven accessories are gone, run electrically instead.
