Watch a Bugatti Veyron hits an incredible top speed of 246 mph (395 km/h) on a public road. This is the Bugatti Veyron Super Sport Pur Blanc special edition version of the hypercar. Even though this track is actually a public road, it was closed for this event. This means that the successful attempt did not endanger any other motorists. This is one of the highest speeds ever recorded on public streets.
