Hennessey Venom GT hits 265.7mph for new world top speed record (+ video)

The Hennessey Venom GT – an American, Lotus Elise-based supercar – has clocked 265.7mph for a new world record top speed for a production car. The world top speed record for a production car has been held by the Bugatti Veyron (well, the Veyron Super Sport) at 258mph, but that’s a ‘limited’ speed for its production cars. The Veyron Super Sport actually hit 267.81mph at VW’s Ehra-Lessian track (it actually hit 269.8mph one way) but because production cars are limited to 258mph the higher speed doesn’t count.
