Our overall rating:
The BMW M3 is a seriously quick and capable four-door saloon. It competes with the Mercedes-AMG C63 and Alfa Romeo Giulia Quadrifoglio, although the latter has the most power of the three.
BMW's mid-sized super-saloon is powered by a twin-turbocharged, straight-six engine driving the rear wheels through a six-speed manual or optional seven-speed dual-clutch automatic gearbox.
The M3 is one of the most hardcore high-performance saloons on the market, but some drivers find it too aggressive. With that in mind, is it the best of its breed?
