The R8 does everything a proper supercar should – and then some. It's rampantly quick in a straight line, especially the Performance version. Its four-wheel drive system keeps things safe and manageable, but you can still have enormous fun. It also has one of the best engines of any supercar car on sale, along with a comfortable interior that makes it remarkably useable every day. For those looking for the absolute last tenth of finesse and purity from their supercar driving experience, though, it must be said that a McLaren 570S eclipses it, while a 911 is both more involving to drive and more practical.
