Supercar design is never about the why – it’s all about the what if? No one will mind if you can’t spot the (almost) imperceptible differences between AMG’s new turbo-charged GT S and its thunderous older siblings (hint: it’s all about the rims). All you really need to know – besides an open-minded bank manager – are these numbers: 515bhp, 0-60 in 3.7 secs, 192mph.
