It is with that in mind that you realise none of these cars looks particularly Rampton day-release, even though each one is fast enough to make your ears clap around the back of your head. So we get subtle(ish) bonnet bulges, wheel arch flares, larger diameter wheels, bigger exhausts and deeper scoops, but no massive spoilers or visually lurid splitters to give the game away.
