Don't know much about the engine, but the race car sounds absolutely fantastic! And like every race car it looks super aggressive.
The road car sounds amazing as well! Is the engine related to the E-type V12? I don't know. But it might be, the cars came out relatively close to each other, so I don't see why they wouldn't be.
So, while it isn't possible for me to own an Italian V12, that's okay cause the English one works just fine.
And to finish it all off. The 7L, 750hp, Group C showstopper.
