Performance Engineering
Drivers will find the most obvious engine improvements in the all-new ZR1X, which will blend the best of the original hybrid Corvette E-Ray with the ZR1’s attributes. A 5.5-liter twin-turbo V8 engine will harness 1,064 horsepower and 828 lb.-ft. of torque, while the electric front-drive unit adds an extra 186 ponies and 145 lb.-ft. of torque. The hybrid system will make the ZR1X the most powerful production Corvette ever, with a total output of 1,250 horsepower, along with electric all-wheel drive (eAWD). An 8-speed dual-clutch transmission will complete the powertrain, providing near-instantaneous gear changes. The ZR1X will feature Stealth Mode, which Chevrolet debuted on the E-Ray; it allows the electric unit to drive solely on electric power for short distances at low speeds. Regenerative brake torque vectoring will help the ZR1X recover energy during cornering by controlling rear inside brake pressure, and front axle pre-control will do the same for the front brakes to maintain consistent grip. The ZR1X’s standard carbon-ceramic brakes will match its acceleration – 0 to 60 in under two seconds – with 16.5-inch front and rear brake rotors paired with Alcon ten-piston front and six-piston rear calipers – the largest ever to grace a production Corvette. The ten-piston front and six-piston rear calipers will also be available on the ZR1 via the ZTK package. For the other variants, the ZR1’s distinctive blue brake calipers will be available on the E-Ray and Z06.
