MERCEDES-AMG C63 S
YES, IT’S A slightly different kind of monster, but these two have been facing off for years, and are more naturally opposed than any Audi option. The AMG is noisier, and being a V8 makes it feel more hairy-chested (as does its 375kW and 700Nm), but the BMW is the one I would want to take to the track because it just feels a touch more feelsome and agile. There’s not much between the two, though, and for some people it may well come down to the style contest, which I suspect many will award to the AMG. The C63 S is a firm-riding machine on the road, but we will have to wait and see if the M3/M4 is any better out in the real world.
