1991 Ferrari 512 TR

Its only its racing rival because it has a similar power to weight ratio, thats it.

Ferrari 512 TR racing rivals
BMW M5 (E60), Lamborghini Gallardo, Porsche 997 Turbo, Ferrari F355, BMW M6,

are you all crazy?

Even ligther? It's hard to belive it since the front-engine 550 (1690kg) is faster in track. 550 its only 3(or less) years newer car than 512M and have 40hp extra to deal with over than 200kg add weight(as Georg says). Also +200kg is realy not good for handling...

A156 the 512TR weight is correct.. it was nearly 200kg lighter as the orginal Testarossa from 1984. The 512M was even lighter

are you sure it weights 1473 kg? I think it's about 100 kg heavier...

It's better to leave your brain "on" all the time. To avoid such silliness :D180 degree 12 cylinder engine whether or not it is boxer or V type can also be called simply "flat 12".

Ok sorry now you can really delete my last few posts. here this is the answer. if not just kill me :P http://upload.wikimedia.org/wikipedia/de/4/43/B6-v6_180.png the difference between a boxer and a 180° V Engine

My bad. I even noticed it's 180 degree cylinder angle but still wrote "V12".

The 512 TR has a Boxer 12, not a V12 :)
