LINK: Supercharged 2015 Chevy Corvette Z06 takes the C7 beyond the ZR1 (w/video)
The new Z06 engine is just an inch taller than the LT1 in the Corvette Stingray, and there are few more powerful inches in the world: the LT4 is a 6.2-liter supercharged V8 producing "at least" 625 horsepower and 635 pound-feet of torque. The integrated 1.7-liter Eaton supercharger and intercooler sit in the engine's vee, that blower spinning beyond the ZR1's supercharger limit of 15,000 up to 20,000 rpm and utilizing shorter rotors to get up to speed more quickly.

Wider, lightweight aluminum wheels are shod with tires that are 1.5-inches wider in front and 2.0-inches wider in back than those on the Stingray, the Z06 gets wider by 2.2 inches in front and 3.15 inches in back. Accentuating the width in back, the taillights have been pushed three inches further apart. The standard Z06 comes with P285/30 ZR 19 Michelin Pilot Sport rubber in front, hiding 14.6-inch steel rotors clamped by six-pot Brembos. In back is 335/25 ZR 20 rubber hiding four-pot calipers. Climb up to the Z07 package and you'll get Pilot Sport Cup tires with Brembo's carbon ceramic rotors that shave 23 pounds compared to the steel units and are 15.5 inches in front, 15.3 inches in back. The suspension on all Z06 trims is a tuned version of that on the Stingray, with Magnetic Ride Control and the electronic limited-slip differential coming standard.
...
The Z07 Package will top it all off and include more bits, but Chevrolet hasn't told us what those bits will be since "development testing is ongoing." It has told us, though, that you'll do faster lap times than in the 2014 ZR1.
