All carbon Fiber with the competition package. Get behind the wheel of the M4 and prepare for explosive acceleration and razor-sharp handling. Power comes from a 425-hp twin-turbo inline-six, with either a six-speed manual or a seven-speed dual-clutch automatic and rear-wheel drive. The Competition package makes 444 hp, but for the ultimate M4, there’s the track-focused, automatic-only, 454-hp M4 CS. While the regular M4 is offered in both coupe and convertible forms, the CS comes hardtop only. All versions ensure legendary M performance.
