Introduction
The M3 is powered by a high-revving 4.0-liter V8 engine that produces 414 horsepower. All that power is driven through the rear wheels via two different transmissions, a six-speed manual or a seven-speed double-clutch, and a variable differential lock. High-performance anti-lock brakes with cross-drilled discs work with electronic stability control and M sport suspension to keep things under control. For 2009, the sedan gets a subtle styling refresh.
