General Motors’s Chevy Corvette Z06 was already a monster with an enormous 670 horsepower from its flat-plane-crank V-8, which could run 60 mph in 2.6 seconds in Car and Driver testing.
But the beast automaker revealed the newest Chevrolet Corvette, the 2025 Corvette ZR1, on Thursday, gearing up to launch the fastest American sports car in history.
The company revealed that the ZR1’s LT7 will be powered by a twin-turbocharged, 5.5-liter, first-ever V8 engine apt for over 1,000 horsepower, and 828 foot-pounds of torque, making it reach the pinnacle of supercars.
The LT7 received massive updates, including a larger combustion chamber, an entirely revised intake system to fit the turbos, intelligent anti-lag engine calibration in the V-8, and a secondary port fuel injection system.
The newest version produces 1064 horsepower at 7000 rpm, which is a 394-hp increase from the ZO6 and can work out 828 pound-feet of torque at 6,000 rpm, compared to Z06’s 460 pound-feet at 6300 rpm.
Chevy has estimated the ZR1’s top speed at over 215 mph and its capability of sub-10-second quarter-mile sprint. However, there are speculations that the ZR1 tires will struggle to translate 1064 ponies to the pavement.
Additionally, the latest Chevy has a sturdier inner and outer input shaft, stronger gears, better oil management, and increased control valves to deal with the high clutch clamp load.
Tadge Juechter, Corvette’s executive chief engineer since 2006, said, “We expect this car to be essentially the fastest car we’ve ever built by a long measure.”
The company said that the prices for the 2025 Corvette ZR1 will be revealed when the vehicle is in the developmental process, which is next year. However, the price point is expected to rise with the introduction of ZR1 and with the sales growth of Z06.
