A Bugatti Veyron, touted as the fastest production roadster in the world, can reach a top speed in excess of 254 mph (409 kph). Even on the German autobahn, known for lacking posted speed limits, this could be considered dangerous, if only because virtually all of the other traffic is traveling at "normal" speeds.
(That speed is 25 to 50 mph faster than the speeds in a NASCAR race.)
The Bugatti Veyron 16.4 SuperSport has the highest top speed. (268mph, 431kph)
