The engine

M256

3.0L Turbo I6 Plug-in Hybrid

Mercedes pairs its silky M256 straight-six with a plug-in hybrid system for long electric-only range plus a strong, refined combined punch — luxury that can glide silently or surge hard.

The straight-six was revived in 2017 specifically because its natural balance and packaging suit electrification; in PHEV form it offers some of the longest electric ranges of any plug-in hybrid.

Some versions can travel over 50 miles on electricity alone before the six even starts.
The inline-six's perfect balance needs no balance shafts, leaving room for the hybrid hardware.
