What is faster - a Ferrari or a Bugatti?

The Bugatti Veyron is faster in a straight line than any factory-spec Ferrari ever made. It is slower, however, around the Nurburgring than the F60 and F430 - probably because of its weight.

Depends on what Lamborghini you are talking about. The Bugatti Veyron has a tested top speed of 256mph, the Veyron 16,4 Grand Sport has a top speed of 256mph and 229mph with the roof down. The Veyron SS reached 267mph, which is the fastest speed for a Bugatti.

The fastest Lamborghini, the Aventador, has a top speed of 217mph so, no, a Lamborghini is not as fast by a long way.
