recently road and track or car and driver..I forget which one..did a test on the cobra, G35, and rx8. Cobra was the faststes, but also came in 3rd, the g35 came in 2nd, and the rx8 won in all around car.
I'm not sure you cannot compare it to the evo or sti, they are both in a different class, and Yes...evo or sti for me ANY day over the rx8.
