265 Mph in a veyron? How? :s I can only get my X1 to 295 without draft.
In terms of lap times it depends on the track. Anything with relatively little turns, and turns that aren't too sharp the Bugetti is hard to beat. Any tracks with a long straight after a hairpin can be a nightmare, as the Bugetti has more power out of the corner than most cars...High speed ring the Veyron is tough to beat.
Other than that, any decent course it will get killed because most race cars take corners like twice the speed of it.
