Corvette Forum user ‘Z0Sick6’ shared a photo over the weekend of a promotional signboard for the 2023 Corvette Z06 that displays the mid-engine supercar’s horsepower output, zero to 60 mph time and quarter-mile time. According to the sign, which appears to be part of a Corvette display at an auto show or race event of some sort, the 2023 Corvette Z06 can clear the quarter-mile in 10.6 seconds. Strangely, the signboard does not include a trap speed with the quarter-mile time.
For reference, the C7 Corvette ZR1 boasted a factory-rated quarter-mile time of 10.6 seconds at 134 mph. That means the new C8 Corvette Z06 has comparable straight-line performance to the C7 Corvette ZR1 despite being down a significant 85 horsepower and 245 pound-feet of torque. These performance gains can be attributed to the C8 Corvette Z06’s mid-engine layout, which puts more weight over the rear wheels, along with other advancements like its sophisticated traction control, quick-shifting eight-speed dual-clutch transmission and sticky Michelin tires.
It’s also worth pointing out that the C8 Corvette Z06 is not a car built for drag racing or roll racing. Developed using know-how from the championship-winning Corvette C8.R race car, the Z06 is intended to be a track-day ringer that can hang with other all-around performance cars on a circuit, like the Porsche 911 GT3 RS and Mercedes-AMG GT R. For that reason, we think a quarter-mile time of 10.6 seconds is plenty quick for most Z06 customers, who will likely be more inclined to take the car to the road course than the dragstrip.
As many readers will already know, the 2023 Corvette Z06 is powered by GM’s new dual overhead camshaft, flat plane crank 5.5L LT6 V8 engine, which is factory rated at 670 horsepower and 470 pound-feet of torque – making it the most potent naturally aspirated V8 engine ever offered in a production vehicle. Power is sent to the rear wheels through an eight-speed dual-clutch transmission and a standard electronically controlled limited-slip differential.
The 2023 Corvette Z06 will enter production at the GM Bowling Green Assembly plant next summer.
