General Motors unveiled the go-faster 2023 Corvette Z06 late last month, introducing a new level of performance for the latest mid-engine Chevy Corvette C8. Among the Z06’s various features is the optional Z07 Performance package, which produces 734 pounds of downforce at 186 mph, “more than any Corvette ever,” according to Chevrolet. However, the 2019 Corvette ZR1 produces more than 1,000 pounds of downforce at 212 mph, so what’s the deal?
To clarify, we reached out to Assistant Manager, Chevrolet Car, Performance and Motorsports Communications, Trevor Thompkins, who provided some insight into the claim that the new 2023 Corvette Z06 produces more downforce “than any Corvette ever.”
“When we’re referring to downforce performance on the new Z06, we’re using 186 mph as the testing point,” Thompkins told GM Authority. “So the new Z06 outperforms the C7 ZR1 at 186 mph in terms of downforce. At 212 mph, the C7 ZR1 was creating over 1,000 pounds of downforce.”
While the standard 2023 Corvette Z06 comes equipped with a front splitter and unique rear spoiler that help the sports car stick at speed, the Z07 Performance package ups the ante with new carbon fiber aero elements like a larger front splitter, front corner dive planes, a larger rear wing, and underbody strakes, all of which add even more downforce than the standard 2023 Corvette Z06 aero package.
The Z07 Performance package also includes Sport Cup 2 R ZP tires, which replace the standard Michelin Sport 4S ZP tires, while braking performance is upgraded with larger carbon ceramic rotors, measured at 15.7 inches in front and 15.4 inches in the rear. Suspension specs with the Z07 Performance package include unique FE7 suspension with specific Magnetic Ride Control 4.0 calibrations.
