N63 · Petrol

Two turbochargers
Two exhaust-driven turbochargers compress the intake air. Charge-air cooling removes heat added during compression.
xDrive all-wheel drive
An eight-speed Sport automatic and xDrive all-wheel drive deliver the V8’s torque. The M850i belongs to the M Performance range; the M8 is a separate full M model.
