How do you miss the power when the Camaro was actually lighter and faster? The Camaro weighs about a good 300-400lbs less and only has 30 less hp/20 less ft lbs of torque...
As a former 6th gen ZL1 owner, I can tell you that you must have had the car in an eco mode or something, because there is no way you could confuse the two otherwise... the ZL1 will match the Hellcat punch for punch all day, and still turn left/right on a dime...
