Back in 2013, the topless version of the Bugatti Veyron Super Sport, the Grand Sport Vitesse, hit a top speed of 254 mph. But tuner John Hennessey thought his creation, the Venom GT Spyder, could go faster. Turns out, yes, the Venom GT Spyder can go faster. A lot faster. What speed did it hit? 265.6 mph. Yeah, that’s pretty darn fast—fast enough to set a claimed world record for fastest convertible. Talk about wind in your hair.
