How’s this for an epic drag race! We’ve got Mat in the all-new BMW M4, and he’s lining up alongside the Mercedes-AMG C63 S & Audi RS5! So how do they match up? First up we've got the M4, and under the bonnet you’ll find a 3-litre straight-six which can deliver 510hp & 660Nm of torque. As for the AMG, well it’s not too different. It may have a 4-litre twin-turbo V8 instead, but it can also deliver 510hp, coupled with 700Nm. Finally we have the RS5, which has a 2.9-litre V6 which can put down 450h
