Power goes to the rear wheels alone, but the previous model’s V8 engine has been replaced with a more powerful and more efficient 425bhp, twin-turbo, 3.0-litre, six-cylinder engine. A six-speed manual gearbox is standard, but the vast majority of UK buyers will opt for BMW’s optional seven-speed dual-clutch ‘M DCT’ auto.
There is, of course, an array of technical trickery as standard, including adaptive dampers, heavily revised aluminium suspension, and an electronically controlled limited-slip differential.
What are the performance rivals the M4 has to overcome? Well, that’ll be the Mercedes-AMG C 63 Coupé and Audi S5, as well as their open-top versions.
