Here's the beef backing that brag: The 7.0-liter LS7 engine will produce at least 500 horsepower at 6200 rpm and 475 pound-feet of torque at 4800 rpm. Revving just slightly past its 7000-rpm redline through base Corvette six-speed gearing, it'll hit 60 mph in first in well under four seconds. The chassis is --drum roll--all aluminum. Magnesium and carbon-fiber parts also are used to help contain the total curb weight to under 3150 pounds. That'll put the new Z06's weight-to-power ratio below both the GT's 6.3 pounds/horsepower and the Viper's 6.8. Aero tuning reduces total lift and balances the front and rear lift coefficients while increasing the base Vette's 0.28 drag coefficient to 0.34.
