More details have come to light regarding the C8 Corvette Stingray’s upcoming hybrid powertrain.
Yesterday, we found out that the Corvette ZR1 will be a hybrid supercar with 900 horsepower. A twin-turbo V8 will be paired with an unknown quantity of electric motors to run on the front axle, giving it all-wheel-drive and stupendous performance.
The report came from MotorTrend and quoted “senior officials” within GM. Now we’re getting more details thanks to documents obtained by Jalopnik with info on the electric motor, battery pack, power electronics, and changes to the chassis and suspension. Not only will the Corvette ZR1 have a hybrid powertrain, but the regular Stingray will also get a hybrid version too.
While the ZR1 will use its electric motor to boost performance into the stratosphere, the base hybrid Corvette will be more about efficiency. It’ll have the same LT2 engine as the current Corvette but will add an electric motor to the front which drives the front axle. That motor should make 114 peak horsepower and provide an additional 111 lb-ft of torque.
Because the electric motor’s peak horsepower won’t arrive at the same time as the 6.2-L V8’s, we can’t just add the two together to make a 600+ hp car, but they should combine to somewhere above 550 horsepower. This would put it on par with the Acura NSX, the other hybrid supercar out there, which has 573 hp from its electrified 3.5-L twin-turbo V6.
In fact, Jalopnik found a lot of similarities with the NSX. The battery pack was almost a direct match and should provide a similar all-electric range too. It sits low and in the middle of the chassis, with the electric motor sitting below the V8 engine. Since it drives the front axle, suspension upgrades were necessary to give the motor space to work.
However, despite running the front wheels, that electric motor is expected to provide a torque boost at low RPM only and is not expected to provide torque vectoring as on the NSX.
There’s been no confirmation from GM on any of this, so take it with a grain of salt. Things can certainly change in the months leading up to the hybrid C8’s arrival.
