The 2014 BMW M4 Convertible brings top-down excitement to the M performance lineup. Its twin-turbo 3.0L inline-six delivers immense torque and razor-sharp throttle response, while the dual-clutch gearbox ensures rapid, seamless gear changes. The metal folding roof retains coupe-like refinement when closed, and transforms the car at the push of a button. Signature M styling cues, adaptive suspension, and a sporty cabin complete this open-air performance machine.
