It's also a good chance to see what the supercharged V8s can deliver at the rear wheels, with the ZL1 managing 497hp and 497lb-ft of torque, and the GT500 bettering that by 98hp and 105lb-ft for figures of 595hp and 602lb-ft of torque. The large discrepancy between Ford
's and GM's latest muscle cars is ultimately explained as being down to the fact GM can't let any car in their stable be more powerful than their flagship ZR1 sports car. So any additional power that is obviously lurking in the ZL1 remains untapped. The GT500 on the other hand has free reign to breathe as deep, loud and as powerfully as possible.
