the 2023 Corvette Z06 produces 670 horsepower and 460 pound-feet of torque for the North American market. To meet European regulations, a gas particulate filter is added which requires a redesigned exhaust system, hence why these cars lose the center-mount pipes for Stingray-style finishers at the corners. In the process, output from the 5.5-liter DOHC engine falls to 636 hp and 439 lb-ft of torque.
