The sound and appearance of the 2023 Chevrolet Corvette Z06 take direction from Corvette Racing. The direct knowledge transfer from the track to the street has never been more evident. The Z06 chassis has underpinned Corvette Racing’s C8.R since it began competing in 2020. Thanks to a shared chassis, similar engine architecture, and exterior proportions, the C8.R has been referred to internally as the Z06 hiding in plain sight.
“Racing was the reason the Z06 was developed in 1963, and it continues to support development of the road models that make them better on the street and the track,” said Tadge Juechter, executive chief engineer, Corvette. “It also means we’ve tested the Z06 on the best tracks around the world, from Circuit of the Americas here in the United States, to the Nürburgring in Germany.”
The Corvette C8.R shined during IMSA’s 2020 sports car championship series, capturing six victories and seven pole positions, and setting the fastest class race laps in six events. During the 2020 series, Chevrolet won the GT Manufacturers title – its 13th since 2001. Jordan Taylor and Antonio Garcia and the No. 3 Corvette C8.R crew won the GTLM Drivers and Team championships.
The performance envelope of Z06 builds on the foundation laid by Stingray, as does Z06’s design language and attention to detail. Expanded material offerings, new interior packages and features unique to Z06 enable owners to create their own bespoke American supercar.
Additional highlights of the 2023 Chevrolet Corvette Z06 include:
- A stance 3.6 inches (9.4 cm) wider than the Stingray, accommodating massive 345-series rear tires and more airflow through side air vents.
- Unique front and rear fascias, a first for Z06. The front fascia is designed to optimize the Z06’s cooling needs, including channeling air to a center heat exchanger, which is one of five for maximum cooling performance.
- A unique, standard reconfigurable rear spoiler with adjustable wickerbill elements designed to improve high-speed stability and cornering capability on a racetrack.
- Standard 20-inch front and 21-inch rear forged aluminum “spider” wheels (with five available finishes) — the largest wheels ever available on a production Corvette.
- Available lightweight and rigid carbon fiber wheels that deliver a 41-pound (18.6-kg) reduction in unsprung mass, which contributes to more agile and responsive handling.
- Specific suspension tuning, including Magnetic Ride Control 4.0, and larger brakes (six-piston front) than the Stingray, contribute to making the 2023 Corvette Z06 the most track-capable Corvette ever.
- Eight-speed dual-clutch transmission with a specific, “shorter” 5.56 final drive ratio compared to the Corvette Stingray, which enhances acceleration capability.
- Elevated cockpit surrounding the driver, with rich materials and textures, including more carbon fiber trim and new options.
- Available Z07 performance package that offers the greatest track capability and provides 734 pounds of downforce at 186 mph, more than any Corvette ever. It includes a carbon fiber high rear wing and ground effects, specific chassis tuning, specific Magnetic Ride Control calibration and unique Michelin® Cup 2 R ZP tires, along with Brembo® carbon-ceramic brakes and optional carbon fiber wheels.
