OK, here's everything I know about the Corvette c8 z06.
About the leaks about different power outputs - they're actually intentional. GM is watching how we react to the different power numbers etc, to know how to advertise the z06.
So far, we know some options (probably for the z07 package):
- Michelin Pilot Sport Cup 2 R tires, 285-30R20s front, and 345-25R21s rear (just for reference, the Corvette C7 ZR1 - the most track focused Corvette to date - had 285-30-19s front and 335-25-20s rear)
- Rear wing,
- Centre exit exhaust
- Carbon fiber rims
- Side canards similar to the camaro zl1 1le
Maybe LED setup similar to the C8 R (not sure about that one).
Engine specs (just speculation for now)
- 5.5 liter flat plane crank DOHC V8 (which may scream like a Ferrari and Lamborghini, while sounding nothing like the two, all the way to 9,000rpm) (Last time they did a DOCH v8 was with the c4 zr1 boat engine)
- 600 - 670 hp
- 470 - 500 lb-ft torque
GM is testing the Corvette C8 Z06 against 2 cars, (besides the c8 stingray of course) - the Ferrari 458 Italia, most likely for driving feel and vibration and the Porsche GT2 RS, most likely to test out the tires.
