The engine

BMW Straight-Six

Twin-Turbo I6

A twin-turbocharged 3.0-liter straight-six in the great BMW inline tradition — perfectly balanced, free-revving, and savage in its M-division 'S' tune where it spins hard to a high redline.

The inline-six has been BMW's signature layout since 1933; in M cars this engine (the S58) is hand-assembled with a closed-deck block and forged crank derived from racing practice.

An inline-six is inherently perfectly balanced — no balance shafts needed, which is why BMW has championed the layout for 90 years.
The M-spec version shares its closed-deck block with BMW's GT racing engines.
