And here is the first test between them:
2009 Chevrolet Corvette ZR1 vs. 2009 Nissan GT-R Comparison Test
This is also the first test I've ever seen where the GT-R is not rated as no. 1.
No wonder, 480 vs 638 hp, the ZR1 is leading in all performance areas, 1/4 mile, top speed, breaking and turning. ZR1 is the fastest and the best.
But as noted in the test on page two the GT-R is far more useful, more easy to take full advange of and is a more advanced car.
A ZR1 on the other hand is a traditonal Corvette with a lots of performance part and a blown 6,3 lire engine in front. That means a cheap interior, low budget solutions and litte to distinguish it from the Z06.
