The 2021 BMW M4 Competition Coupe has been officially unveiled. The new flagship model features the same polarising kidney grille design as the 4 Series Coupe, and is powered by a 503bhp twin-turbo petrol engine. Sales are due to start in March 2021, with prices set to be confirmed in the coming months. The new M4 has been revealed alongside the mechanically identical BMW M3 saloon.

Under the bonnet will be a 3.0-litre six-cylinder petrol engine with two turbochargers. The M4 Competition (the only model coming to the UK) produces 503bhp and is only available with an eight-speed automatic gearbox, while other European countries will get a base model with 473bhp and a six-speed manual.

The Competition spec car sprints from 0-62mph in 3.9 seconds and has an electronically limited top speed of 155mph - but you can reach 180mph if you spec the optional M Pro Package. Fuel economy is clearly a secondary consideration; you can expect 27.7mpg when you’re not driving quickly. CO2 emissions start at 234g/km.
