There will be some significant changes to the mid-engine C8 Corvette in its third year, including modifications to the V-8 engine. However, until the 2023 model year, Chevrolet will only introduce an even more focused Z06 variant that improves on the Corvette’s already supercar-level performance. The AWD hybrid Corvette E-Ray may debut as well eventually.

The 6.2-liter pushrod naturally aspirated V-8 in the Chevrolet Corvette Stingray produces 490 horsepower and 465 lb-ft of torque—495 hp and 470 lb-ft with the Z51 performance exhaust—and transmits power to the rear wheels via an eight-speed dual-clutch automatic gearbox.

The C8 Corvette’s price-defying performance statistics drew gasps and demanded headlines when it was first released, and it remains a spectacular sports car. An example with the Z51 performance package accelerated to 60 mph in 2.8 seconds and a quarter-mile in 11.1 seconds at 123.2 mph in our First Test (though we’ve tested a few C8s now, launch control is unreliable). It also delivers respectable fuel economy; the 2021 Corvette is rated at 15/27 mpg city/highway by the EPA.
