By which standards, who’s rules, under which conditions…..
And what are the exceptions?
It’s not a Veyron or an F1! (although they both hold world records!)
In this case – no one has officially (by someones rules), ever gone faster, from stand still until they reach a mile (1,609Km!), in a road legal car. 283Mph.
So therefore the rule makers, in this case Guinness, has awarded them a diploma!
McLaren F1 is the fastest naturally aspirated production car in the world and its from 1992! Bugatti Veyron is the fastest production car in the world.
