New (2014) BMW M3 and M4: OFFICIAL

The new BMW M3 (pictured) debuts along with its coupe sibling, the BMW M4 (below) We’ve had teases from BMW for the new M3 and M4 but now, ahead of a public debut at the Detroit Auto Show next month, we get the official details. Key to the four-door M3 and 2-door M4 is the new 3.0 litre engine, a new turbo, direct injection in-line six petrol which produces 425bhp and a very healthy 405lb/ft of torque from just 1850 rpm. That sort of grunt is enough to get the M3 and M4 to 62mph in 4.3 seconds with the standard six-speed manual, but opt for the seven-speed DCT ‘box and it’s even quicker – just 4.1 seconds.

It's a hydrogen fuel-cell vehicle, and Merc claims a punchy 1000km (620-mile) range.
