We already knew that Chevrolet is working on a 5.5-liter flat-plane-crank V-8 that is going to power the upcoming C8 Corvette Z06, the ZR1, and the hybrid Zora.

Rumors are it will produce 600 to 1000 horsepower with turbochargers and an electric motor (driving the front wheels) and have a Ferrari-rivaling sound. We have seen spy photos with electric motor diagnostic wires hanging out the front hood.

New information suggests that the Grand Sport variant could be powered by a hybridized version of the 6.2-liter V-8 that powers the 2020 Corvette Stingray, according to a leaked document obtained by Hagerty. That leaked information also lays out the model years and powertrains of all the upcoming high-performance Corvette variants.
