10 Incredible Numbers That Define the 2026 Chevrolet Corvette ZR1X

Numbers don't lie, and the 2026 Chevrolet Corvette ZR1X has some truly extraordinary ones to share. Since its announcement in June, automotive enthusiasts have been poring over the specifications of what Chevrolet calls North America's first true hypercar. Each figure tells part of a larger story about pushing engineering boundaries.

These numbers matter because they translate directly into real-world performance. From acceleration times that seem impossible to power figures that rewrite the rulebook, the ZR1X delivers performance data that places it among the world's most capable supercars. Here are ten incredible numbers that capture why this machine advances automotive engineering.

1,250 Horsepower: Total System Output

The headline figure that stops conversations is 1,250 horsepower of combined system output. This astronomical number comes from the marriage of two distinct power sources working in harmony. The LT7 twin-turbo V8 engine contributes 1,064 horsepower, while the front-mounted electric motor adds another 186 horsepower. Together, they create more power than most people will ever experience in a single vehicle.

These numbers go beyond bragging rights – this power allows the ZR1X to accelerate a 1,700-kilogram machine with the ferocity of a much lighter sports car. The all-wheel drive system ensures that every bit of this power reaches the pavement effectively.

Under 2 Seconds: Zero to 96 km/h Acceleration

General Motors estimates the ZR1X will sprint from zero to 96 km/h in under two seconds. To put this in perspective, most people need longer than two seconds just to react to an emergency while driving. This acceleration figure places the ZR1X among the quickest-accelerating production cars ever built, regardless of price or country of origin.

The secret lies in the instant torque delivery from the electric front motor, which eliminates the brief delay typically experienced with turbocharged engines during launch.

1,064 Horsepower: LT7 V8 Engine Output

The hand-built LT7 V8 engine produces 1,064 horsepower at 7,000 rpm, making it the most powerful V8 ever produced by a North American auto manufacturer. This 5.5-litre twin-turbo powerplant features a forged flat-plane crankshaft and dry-sump lubrication system, technologies borrowed from racing applications.

Each LT7 engine is assembled by master engine builders at the Bowling Green Performance Build Center, ensuring consistent quality and attention to detail that mass production simply cannot match.

828 lb-ft: Peak Torque from the V8

The LT7 engine delivers 828 lb-ft of torque at 6,000 rpm, providing the massive pulling power needed to move the ZR1X with authority. This torque figure, combined with the electric motor's instant delivery, creates a powerband that feels limitless across the entire rev range.

The twin 76-mm turbochargers use a unique "maniturbo" exhaust design that positions them as close to the exhaust valves as possible, reducing turbo lag and improving throttle response throughout the power curve.

Under 9 Seconds: Quarter-Mile Performance

The ZR1X will complete the quarter-mile in under nine seconds with a trap speed exceeding 241 km/h. These are numbers typically associated with purpose-built drag racing cars, not street-legal vehicles that can also tour comfortably or tackle road courses.

The front electric motor remains engaged through speeds up to 257 km/h, directly contributing to these straight-line acceleration figures while providing additional traction and stability.

16.5 Inches: Record-Breaking Rotor Diameter

The ZR1X features 16.5-inch carbon ceramic rotors front and rear – the largest diameter rotors ever offered on a Corvette. These massive rotors work with Alcon 10-piston front and 6-piston rear calipers to provide stopping power worthy of the hypercar's performance.

During testing, J59-equipped Corvettes achieved 1.9G of deceleration when slowing from 289 to 192 km/h, demonstrating the system's incredible capability under extreme conditions.

1,200 lbs: Maximum Downforce

The optional Carbon Aero package generates up to 1,200 lbs of downforce at top speed. This massive aerodynamic force helps keep the ZR1X planted to the road surface during high-speed cornering and straight-line runs. The package includes dive planes, underbody strakes, a hood gurney lip, and a highly effective rear wing.

This level of downforce is comparable to some professional racing cars, yet it's available on a vehicle you can drive to the grocery store.

257 km/h: Front Axle Engagement Speed

The front electric motor can apply power through speeds up to 257 km/h before disconnecting. This extended engagement range means the all-wheel drive system remains active far beyond typical driving speeds, benefiting both acceleration and cornering balance during track sessions.

Most all-wheel drive systems disengage the front axle at much lower speeds to reduce drivetrain losses, but the ZR1X's electric front end operates differently, maintaining its contribution to performance at speeds that matter on road courses.

1.9G: Maximum Deceleration Force

During brake testing, J59-equipped Corvettes achieved 1.9G of deceleration – nearly twice the force of gravity. This means the car can slow down faster than most people can comfortably handle, requiring considerable physical strength to brace against the forces involved.

General Motors describes the J59 braking system as "the most resilient production car braking system we've tested within GM," highlighting its ability to maintain performance under repeated heavy use.

5.5 Litres: LT7 Engine Displacement

The LT7's 5.5-litre displacement strikes the ideal balance between power output and packaging constraints. This relatively compact V8 fits within the mid-engine Corvette's architecture while generating more power per litre than most naturally aspirated engines could ever achieve.

The engine's flat-plane crankshaft design allows it to rev freely while maintaining the distinctive exhaust note that Corvette enthusiasts expect from their V8 powerplant.
