It depends on what type of cars they are, for say a bugatti veyron grand sport is faster then a lamborghini murcielago. but a lamborghini veneno is faster then a bugatti EB110 a bugatti EB110 is faster then a lamborghini countach. but if you supercharged a bugatti EB110 it would be as fast as a lamborghini veneno.
The Veyron ,if your wallet can handle it
If you mean top speed. Bugatti Veyron 407 kmph (252 mph) Bugatti Veyron Supersport 431 kph (267 mph) Bugatti EB110 343 kmph (213 mph)
In 1991: the Bugatti EB110 GT at 213mph
The founder was Ettore Bugatti, hence the iconic EB in the badge and in the name of the predecessor to the Veyron, the EB110.
Which Bugatti? EB110, Type 35, Royale, Galiber, Type 57? What? I'm assuming you mean Veyron so: Bugatti
a Bugatti galiebier can go up to 268.8mph
'''260mph'''
A Bugatti Supersport can go 268mph.
253mph
A Bugatti Veyron's top speed is 253mph (407kph)
not fast really really really fast
