A pre-production prototype C8 Corvette Z06 was recently spotted testing on public streets with what looks to be a new, production-ready exhaust setup.
This exclusive GM Authority photo shows a C8 Corvette Z06 prototype with four individual tips placed in a row mounted in the center of the rear bumper. This differs from other C8 Corvette Z06 prototypes we’ve spotted, which featured a similar exhaust setup to the C8 Corvette Stingray with two separate sets of twin-tip exhausts mounted on either side of the rear bumper. The C8 Corvette Stingray tips are also square, whereas this Z06 prototype has large rounded tips with a matte black finish. This new setup has allegedly been implemented to improve the C8 Corvette Z06’s exhaust note.
The rear fascia on this prototype is also different, incorporating new vents on the outer edges of the bumper. The rest of the rear end is covered up by some black camouflage, likely signalling the presence of other rear fascia styling changes. It’s worth noting this prototype does not have the large available rear wing that we’ve seen on other C8 Corvette Z06 prototypes, which will be offered as part of the Z07 Performance Package and will therefore not be present on all Z06 models.
The C8 Corvette Z06 will be powered by a new 5.5L V8 LT6 engine, which will feature a flat-plane crankshaft. The DOHC 32-valve motor is expected to make around 615 horsepower and 450 pound-feet of torque. A version of GM’s Tremec-supplied eight-speed dual-clutch transmission will be present, sending power to the rear wheels through an electronically controlled limited-slip differential.
GM is preparing to pull the wraps off of the C8 Corvette Z06 sometime later this year as a 2023 model year product. The high-performance Corvette variant will be built alongside the standard C8 Corvette Stingray at the GM Bowling Green Assembly plant in Kentucky.
