The Corvette ZR1 makes up to 1,064 hp (793 kW) at 7,000 rpm from a twin-turbocharged 5.5L flat-plane crank V8 mounted behind the seats. An 8-speed dual-clutch transmission sends that power to the rear wheels. The car runs 0 to 96 km/h in an available 2.3 seconds.
Chevrolet Canada calls it a mid-engine, two-seat supercar. If you search “Corvette ZR One,” you’re looking for the same car. People say “ZR One” out loud and type “ZR1.” This article shows where the power comes from and how it translates on the road around Mississauga. You can also browse the Chevrolet Corvette ZR1 inventory at Addison GM at any time.
How the Corvette ZR1 Makes 1,064 Horsepower
No single part creates that number. The output comes from several things working together.
- The engine. A twin-turbocharged, direct-injected 5.5L DOHC V8 with a flat-plane crankshaft.
- The layout. The engine sits mid-ship, helping the car put its power down on launch.
- The hardware. Carbon ceramic brakes are standard, and available aero adds downforce.
Any one of these would make a car quick. Together, they explain the ZR1 numbers.
The Twin-Turbo V8 Behind the 2027 Corvette ZR1 Power
Under the carbon fibre display hood sits the LT7, a 5.5-litre DOHC V8. Twin turbochargers force extra air into the cylinders, and direct injection feeds in fuel with precision. That combination lets a 5.5L engine reach up to 1,064 hp.
Why the Flat-Plane Crank Matters
The LT7 uses a flat-plane crankshaft, a design long linked to high-revving racing engines. It lets the V8 spin freely toward its 8,000 rpm redline. It also gives the engine a sharp, rapid-fire sound.
The ZR1 pairs peak power at 7,000 rpm with that 8,000 rpm redline. The result? The engine keeps pulling hard across a wide rev range. Chevrolet Canada quotes an available quarter-mile time of 9.6 seconds at 241 km/h (150 mph).
Cooling the Power
Making 1,064 hp creates serious heat, so airflow matters as much as boost. A flow-through hood and spoiler pull air out of the intercoolers. Cooler air is denser air, and denser air means more power.
Mid-Engine Layout Puts the Power Down
A mid-engine car places the engine behind the driver and ahead of the rear axle. That’s the classic supercar arrangement, and the Corvette ZR1 uses it.
The layout puts more weight over the rear wheels, which helps traction when you launch hard. It also keeps the car’s mass centred for sharp handling. Power then goes to the rear wheels through the 8-speed dual-clutch transmission. The ZR1 has a curb weight of 1,665 kg, which is a lot of output for a two-seater of that size.
Aero, Brakes and Track Hardware
Big power needs equipment that can use it and control it. A front splitter, underwing, and smooth underbody add downforce and cut drag. The brakes and suspension, meanwhile, are built for repeated hard use.
Track-focused equipment includes:
- Carbon ceramic brakes (standard)
- ZR1/ZR1X Carbon Fibre Aero Package (available), with a carbon fibre wing, underbody strakes and dive planes
With that aero package, the ZR1 generates over 544 kg (1,200 lb) of downforce. That grip comes from the air itself and builds with speed.
How Fast Is the Corvette ZR1?
Very fast. Here are the figures Chevrolet Canada publishes for the Corvette ZR1:
| Measure | 2027 Corvette ZR1 (manufacturer-rated) |
| Horsepower | Up to 1,064 hp (793 kW) @ 7,000 rpm |
| Redline | 8,000 rpm |
| 0 to 96 km/h (0-60 mph) | 2.3 seconds (available) |
| Quarter-mile | 9.6 seconds at 241 km/h / 150 mph (available) |
| Downforce | Over 544 kg / 1,200 lb (with available aero package) |
What does 2.3 seconds feel like? Count “one, two” out loud. By the time you finish, the ZR1 can reach 96 km/h. Picture merging onto the 401 near Mississauga.
The quarter-mile figure tells a similar story. In less than 10 seconds, the car covers about 400 metres and crosses 240 km/h.
Keep in mind that these figures are manufacturer-rated. Real results depend on equipment, tires, temperature and surface. Check with the dealer for anything beyond the numbers above. You can also review the full spec sheet on the Chevrolet Canada Corvette ZR1 page.
