2027 Chevy Corvette Grand Sport X
The 2027 Chevrolet Corvette Grand Sport X takes the familiar Grand Sport formula and adds something the name has never had before: an electric motor driving the front wheels. The result is a hybrid all-wheel-drive sports car with 721 combined horsepower, instant front-axle torque, and performance technology borrowed from the much more powerful Corvette ZR1X.
Key Takeaways:
- The Grand Sport X combines a 535-horsepower LS6 V8 with a 186-horsepower front electric motor.
- Total system output is 721 horsepower and 665 lb.-ft. of torque.
- All-wheel drive comes from the front electric motor rather than a conventional mechanical driveshaft.
- Chevrolet estimates 2.4 seconds from 0 to 60 mph and a 10.4-second quarter-mile at 131 mph.
- The Grand Sport X starts at $109,700, while Chevrolet lists the model as arriving in fall 2026.
How is the Corvette Grand Sport X different from the regular Grand Sport?
| Feature | 2027 Grand Sport | 2027 Grand Sport X |
|---|---|---|
| Gas Engine | 6.7L LS6 V8 | 6.7L LS6 V8 |
| Total Horsepower | 535 hp | 721 hp |
| Total Torque | 520 lb.-ft. | 665 lb.-ft. |
| Drivetrain | Rear-wheel drive | Electric all-wheel drive |
| 0–60 mph | 2.75 sec. | 2.4 sec. |
What engine powers the 2027 Corvette Grand Sport X?
The Grand Sport X uses Chevrolet's new naturally aspirated LS6 6.7-liter V8. The engine produces 535 horsepower and 520 lb.-ft. of torque on its own, making it the foundation of the hybrid system rather than an engine supplemented by a turbocharger.
The LS6 uses a 13.0:1 compression ratio, a 100-mm stroke, forged internal components, revised exhaust manifolds, and a new continuously variable oil pump. Chevrolet also describes its 520 lb.-ft. of torque as the highest torque figure ever offered by a naturally aspirated production V8.
That naturally aspirated character matters to the Corvette's personality. The engine delivers its power without turbochargers, while the electric motor supplies immediate torque when the driver needs additional traction and acceleration.
How does the Grand Sport X's electric motor work?
A 1.9-kWh lithium-ion battery sits low and centrally in the car. Chevrolet designed the system around performance rather than long electric driving range, allowing the motor to provide short bursts of additional power and traction without turning the Corvette into a plug-in sports car.
Chevrolet also gives the driver different energy-management strategies. Endurance mode is designed to preserve battery energy during extended track sessions, while Qualifying prioritizes maximum available performance. Push-to-Pass provides maximum available power on demand.
Can the 2027 Corvette Grand Sport X drive on electric power alone?
Yes, but only for limited low-speed or short-distance use. Chevrolet's Stealth Mode allows the Grand Sport X to travel solely on electric power for approximately 4 to 5 miles at speeds up to 50 mph.
Shuttle Mode can move the car using the electric motor alone at speeds below 22 mph, such as maneuvering around a driveway or garage. Chevrolet specifically notes that Shuttle Mode is not intended for public-road driving.
These functions are primarily about flexibility and low-speed maneuvering rather than electric commuting. The Grand Sport X remains fundamentally a high-performance gasoline sports car.
What makes the Grand Sport X different on a track?
The electric front axle is most important when the driver gets back on the throttle. The motor can send up to 145 lb.-ft. of torque to the front wheels almost immediately, helping the car put its power down while exiting a corner.
The Grand Sport X also comes standard with carbon-ceramic brakes, Magnetic Ride Control, enhanced powertrain cooling, and Performance Traction Management. Chevrolet pairs those systems with wide Michelin tires measuring 275/30ZR-20 at the front and 345/25ZR-21 at the rear.
Car and Driver's first drive found that the Grand Sport X carried noticeably more speed out of corners than the rear-wheel-drive Grand Sport it tested alongside. The publication also noted that tire choice changes the driving character, with the available summer tires providing more immediate response than the standard all-season setup.
How fast is the 2027 Corvette Grand Sport X?
Chevrolet quotes an available 2.4-second 0-to-60-mph time and a 10.4-second quarter-mile at 131 mph. Those figures put the Grand Sport X firmly into supercar-level acceleration territory despite its naturally aspirated V8.
Car and Driver's independent first-drive testing did not yet produce a full instrumented acceleration test, but the publication estimates approximately 2.5 to 2.6 seconds to 60 mph and a 10.6- to 10.7-second quarter-mile.
The difference between Chevrolet's available figure and Car and Driver's estimate is worth noting because they are not the same type of measurement. Chevrolet's number is an advertised performance figure, while Car and Driver's numbers are estimates based on its testing experience.
How efficient is the Corvette Grand Sport X?
The hybrid system does not turn the Grand Sport X into a fuel-efficient sports car, but it does produce a small efficiency advantage over the regular Grand Sport. Car and Driver lists the Grand Sport X at 18 mpg combined, compared with 17 mpg combined for the rear-wheel-drive Grand Sport. Its estimated EPA figures are 15 mpg city and 24 mpg highway.
The 18.5-gallon fuel tank gives the Grand Sport X an estimated highway range of roughly 444 miles based on those EPA figures. Actual range depends on driving style, traffic, speed, weather, and how frequently the car is driven in high-performance conditions. Edmunds lists the same 18.5-gallon tank capacity.
What does the Grand Sport X cost?
Chevrolet currently lists the 2027 Grand Sport X with a starting MSRP of $109,700. Its website also shows an example vehicle priced at $122,210, illustrating how quickly options and equipment can move the price upward.
Car and Driver lists the Grand Sport X at $112,195 for the coupe and $119,195 for the convertible, while Edmunds currently lists the model from $109,700 to $127,350 depending on configuration. Differences can reflect destination charges, body style, trim level, and equipment.
Is the 2027 Chevy Corvette Grand Sport X Worth Purchasing?
The 2027 Chevrolet Corvette Grand Sport X is a very different interpretation of the Grand Sport formula. The naturally aspirated LS6 V8 provides 535 horsepower on its own, while the front electric motor adds another 186 horsepower and creates electric all-wheel drive. Because the 2027 Corvette Grand Sport X is arriving in fall 2026, availability will depend on when individual cars enter production and reach dealers.
