Sources close to the SAE testing of the 2012 Camaro ZL1 has said that the ZL1 will come in at over 570 horsepower. Original estimates were somewhere around 550 horsepower (based on the similarity to the CTS-V). The ZL1 will also likely be getting the Corvette ZR1′s Traction Management System to help heavy-footed operators keep the car on the road and not in the ditch.
We’ll see how this shakes out and make sure to give you the official SAE verified numbers when they’re released. This comes at an interesting time with the rumor of the 2012 GT500 having 650 Horsepower. The horsepower wars should be a fun thing to watch.
