5. Porsche 911 GT2 RS

This is where the world’s best-loved sports car gets a bit silly. There has never been a faster or more powerful 911 than the 690bhp, 211mph GT2 RS. This uber-911 seeks to combine the involving track focus of the GT3 RS with a level of torque and sheer brute force performance that even a 911 Turbo S struggles to match, with the latter channelled through one driven axle rather than two. It’s quite a mission statement — and, if only by Porsche’s own high standards, it’s not entirely successfully delivered upon.

But such a tiny detail needn’t necessarily come between any GT2 RS owner and the appreciation of what remains a staggeringly compelling driver’s car, because the GT2 RS is remarkably good at keeping its ridiculousness largely in check most of the time, unleashing it only when you want it to. The car uses 21in rear wheels and 325-section tyres to transmit its venom to the Tarmac. It has carbon-ceramic brakes as standard and a suspension set-up even more specialised than that of a GT3 RS.
