Yahoo Autos Chevy Corvette C8 High-Performance Models' Powertrain Details Leaked
The world now knows all about the 2020 C8 Corvette Stingray, but there are many more high-performance C8 Corvette models to come.
The Z06, the ZR1, and the Zora hybrid will use a 5.5-liter flat-plane-crank V-8 engine, and the Grand Sport may use a hybrid version of the 6.2-liter V-8, according to a leaked document found by Hagerty.
The document states that the Z06 will arrive first as a 2022 model, with the Grand Sport arriving for 2023, the ZR1 for 2024, and the Zora as a 2025 model.
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. We were aware it could produce 600 to 1000 horsepower with turbochargers and an electric motor and have a Ferrari-rivaling sound. 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. Adding the new details in this document to what we already know about Chevy's plans, here's what we predict:
2022: Z06
We previously reported that the C8 Z06 will use a naturally aspirated DOHC 32-valve 5.5-liter V-8 with a flat-plane crank, just like a Ferrari V-8, that should rev to between 8500 and 9000 rpm. The document sent to Hagerty says that it'll produce 650 horsepower and 600 lb-ft of torque. That means the 5.5-liter would produce about 118 horsepower per liter, 20 percent more than the Ford Mustang Shelby GT350's 5.2-liter flat-plane-crank V-8, which has an output of 101 horsepower per liter. We expect the C8 Z06 to go on sale in early 2021 as a 2022 model, starting at about $85,000.
