that SSC Aero is the quickest now, but yer the Bugatti people think the Guiness world records are a crock of shit (which is fair enough) and never did a run for their world records - thus the people at Guiness (who believe if its not in their stupid book it never happened) came out and said incorrectly, this was the fastest car in the world.

Just how fast is 388 km/h? in (MPH)

cullpearlyellow the Veyron did 407kmh

Bugatti went 407 km/h

Well there go's the Vayrons record

so it beats the bugatti vayron which was at 366 km/h???
