? Which Lambo and which Ferrari? Ferrari F430 has a 1mph higher top speed than its competitor Lamborghini Gallardo, but the Gallardo accelerates a bit quicker. Same handling. Ferrari Enzo has a 4mph higher top speed than the Lamborghini Murcielago, same accelerations and handling. The Stig drove the Ferrari F430 and Lamborghini Gallardo and they got the exact same lap times. So some Ferrari's are faster and some Lamborghini's are faster and some are the same.
If its all out power on a straight stretch of road, i would go with Ferrari, if it comes to track-racing, it would be much more dependant on A): Driver Skill (or lack thereof), B): Which car is quicker through the twists and turns, C): Which car has superior tyres, etc. But, mph for mph, if thats the raw stats you're after, then it simply HAS to be the Ferrari Enzo... Then again, the Bugatti Veyron just bangs both of the above into the bush, with a top speed in excess of 400km/h. Hope this helps...
