"We already know that the ZL1 will have a 580-hp, supercharged V-8-engine similar to the one stuffed in the CTS-V and Corvette ZR1. We also know the ZL1 laid down an impressive 7:41.27 lap time around the Nurburgring. And today, we learn that its curb weight is
4,120 pounds (weight distribution of
51/49), which is almost 300 pounds more than the Camaro SS that sits below it. Yes, it is heavy and now we know why Chevy spent a lot of time developing and tinkering with the suspension and Performance Traction Management system."
