The Z06 has more torque, less weight, and near perfect 50/50 weight distribution. Road & Track tested itÂs 0-60:4.5 sec, 0-100:9.9 sec, and Å mile:[email protected] mph. In pure numbers the Z06 owns the ZR1. Go to the SCCA Solo II and look at the 2002 Nationals archives and you will see that the ZR1 isnÂt even in the same class as the Z06. If you compare the best times of C5 corvettes (SS) vs. the times of the C4Âs ((AS)including the ZR1) you will see that the C5Âs rule in handling as well. THE Z06 IS SUPERIOR IN EVERY WAY!
