The M3 is arguably one of the most sought after BMWs, and with good reason, as it provides a combination of performance, handling, and practicality rivaled by few competitors. BMW now offers three M3 variants: coupe, sedan, and convertible, all powered by a new high-revving 4.0L V-8. A new 7-speed dual-clutch transmission (DCT) replaces the unloved SMG automatic, while the 6-speed manual remains the standard gearbox.
