The Mercedes-Benz M275 (and similar M285) engine is a twin-turbocharged and intercooled, all-aluminium, 60° V12 automobile piston engine family used in the 2000s to the 2010s. It is loosely based on the M137 naturally aspirated V12 sold between 1998 and 2002, and retains its SOHC, 3 valves per cylinder, twin-spark ignition layout, but differs with the addition of structural reinforcements to the engine block for improved rigidity which in turn yields greater reliability. The M275 V12 Bi-Turbo engine was modified with the addition of larger turbochargers.^[1] Several variations of the M275 V12 Bi-turbo engine have powered many top-of-the-range Mercedes-Benz and Maybach models since 2003.
