The 2023 Corvette Z06 has made its long-awaited debut, appeasing American performance enthusiasts with a naturally aspirated, flat-plane crank V8 engine producing an impressive 670 horsepower.
Chevy says the all-new 5.5L LT6 V8 featured in the 2023 Corvette Z06 is the highest horsepower naturally-aspirated V8 ever offered in a production vehicle. The engine features a lightweight, low-inertia rotating assembly with a flat-plane crankshaft, enabling a sky-high redline of 8,600 rpm. Other highlights of the dual-overhead camshaft motor include an all-aluminum cylinder block, forged aluminum pistons, forged titanium connecting rods, an active split intake manifold with twin 87 mm throttle bodies and a racing-inspired dry-sump oiling system, among more. Output is GM-estimated at a healthy 670 horsepower and 460 pound-feet of torque.
Power in the 2023 Corvette Z06 is sent to the rear wheels through the eight-speed dual-clutch transmission with a shorter 5.56 final drive ratio, further helping to give the Z06 superior acceleration over the Stingray. Chevy’s now-familiar electronic limited-slip differential is also present and works with a new track-specific Performance Traction Management system to put power to the pavement. Available when Track mode is activated, Chevy says the Performance Traction Management system in the Z06 offers five settings of torque reduction and brake intervention, allowing the user to tailor it to their needs when out on the track.
Braking in the “standard” Z06 is handled by a set of 14.6-inch-diameter front and 15-inch-diameter rear Brembo brake rotors, along with front six-piston and rear four-piston Brembo calipers. The 20-inch front wheels are shod in wider 275/30ZR20 tires, while the larger-diameter 21-inch rear wheels are wrapped in a set of 345/25ZR21 tires. Michelin Pilot Sport 4S ZP tires are standard equipment as well. These standard models offer available Magnetic Ride Control suspension and are equipped with monotube shock absorbers front and rear.
Customers who crave even more performance can opt for the available Z07 Performance Package. The Z07 pack takes the performance of the C8 Corvette Z06 “to its zenith,” Chevy says, adding larger, carbon ceramic 15.7-inch-diameter front rotors and 15.4-inch-diameter rear rotors, along with stickier Michelin Sport Cup 2 R ZP rubber, FE7 suspension with specially tuned Magnetic Ride Control 4.0 dampers, and available carbon fiber wheels that deliver a 41-pound reduction in unsprung mass. All Z07-equipped models also receive a full carbon fiber aerodynamics package with a larger front splitter, front-corner dive planes, a rear wing and an underbody strake. The aero kit produces 734 pounds of downforce at 186 mph.
Inside, the Z06 offers available carbon fiber-wrapped steering wheel, carbon fiber dash/door trim, three different seat choices and six seat belt options. A head-up display is also standard, relaying important information to the driver even while their full attention is on the track ahead.
Chevy says the 2023 Corvette Z06, which will be offered in both Coupe and Convertible body styles, will have a total of twelve available exterior colors from launch, along with seven interior colors and six different brake caliper colors. There will also be eight available wheel packages, including six finishes on the standard forged aluminum wheels and the aforementioned carbon fiber wheels. Production of the 2023 Corvette Z06 will begin at the GM Bowling Green Assembly plant in summer 2022. Chevy has not yet confirmed pricing or fuel economy figures, but mentioned a 0-to-60 mph time of 2.6 seconds, and Z07-equipped cars can circle a 300-foot skidpad at 1.22 g.
