This came out yesterday, which I actually thought this was going to link to:
2014 Chevrolet Camaro Z/28 vs. 2014 Nissan GT-R Track Edition! - Head 2 Head Ep. 52 - YouTube
I won't spoil the ending, but suffice to say the GT-R smokes the Camaro in a straight line (duh), but is much more game when it comes to road and track use. If nothing else, we should be happy with the progress Mustang and Camaro have made to make their cars actually enjoy any sort of turn.
Then again, the GT-R is still more or less a 5 year-old vehicle.
