The Bentley Speed 8 prototype that won at Le Mans in 2003 had a top speed of 215mph, with power coming from a 4.0-litre twin-turbocharged V8 developed by Audi, but if you prefer your test of speed to focus more on cornering, acceleration and not falling off a massive terrifying cliff, then it’s hard to ignore the limited edition Conti GT that broke the production car record at Pikes Peak in 2019.
