300+

If you have beaucoup bucks and are really competent, you too can do this as the Bugatti Chiron is a street-legal car of a different kind.

Ever since the Bugatti Chiron was launched, with a 261-mph speed limiter, we've been desperate to know what it could manage if let off the leash. Now Bugatti has done that at the vast Ehra-Lessien test track in Germany; the car smashed both the production-car record and the 300-mph barrier.

Factory test driver Andy Wallace, who previously set production-car records in both the Jaguar XJ220 and the McLaren F1, drove a slightly modified Chiron to a time, certified by the German TÜV organization, of 304.773 mph.

300+ indeed.
