2027 Chevrolet Corvette Lineup Expands with 535-HP LS6 V-8 and All-New Hybrid Grand Sport X

The 2027 Chevrolet Corvette Stingray and Grand Sport models arrive with significant mechanical updates, headlined by a fresh naturally aspirated powerplant and expanded performance trim options. Car and Driver reports that Chevrolet's mid-engine sports car family gains a new 6.7-liter LS6 V-8 engine delivering 535 horsepower and 520 pound-feet of torque, alongside the return of the iconic Grand Sport nameplate and an all-new hybrid model.

Fresh V-8 Power and Dual-Clutch Performance

At the core of the 2027 Corvette Stingray and Grand Sport is a pushrod 16-valve 6.7-liter (409-cubic-inch) aluminum-block V-8 utilizing both port and direct fuel injection. Peak output reaches 535 horsepower at 6,100 rpm and 520 pound-feet of torque at 4,600 rpm. Power is sent exclusively through an eight-speed dual-clutch automatic transmission operated by center-console push buttons and large steering-wheel-mounted shift paddles; a manual transmission is not offered.

For rear-wheel-drive configurations, Chevrolet pairs this output with launch metrics that Car and Driver estimates will push the car to 60 mph in under 3.0 seconds—specifically 2.7 to 2.8 seconds for the Grand Sport. Additional performance estimates from Car and Driver place the Grand Sport's 100-mph sprint at 7.0 to 7.1 seconds, the quarter-mile time at 10.9 to 11.0 seconds, and top speed between 180 and 186 mph.

Grand Sport Returns Alongside Hybrid Grand Sport X

The 2027 Grand Sport returns to offer driver-focused features, including a standard adaptive suspension and capable handling that achieves over 1.0 g of lateral grip. Buyers seeking enhanced track capabilities can select the available Z52 track Performance package, which adds carbon-ceramic brakes, a honed suspension setup, a carbon-fiber front splitter, a rear wing, and additional aerodynamic modifications. The existing Z51 package also remains available, introducing an electronically limited-slip rear differential, summer tires, and upgraded brakes.

Replacing the recently departed E-Ray, the new Grand Sport X blends the Z06 model's widebody design with electrified hardware. It pairs the 535-hp LS6 V-8 powering the rear wheels with a 186-hp front-mounted electric motor sourced from the top-tier ZR1X. Combined, this setup provides all-wheel drive and total system output of 721 horsepower.

Pricing and Packaging Options

According to Car and Driver, base pricing for the 2027 Chevrolet Corvette Grand Sport lineup spans multiple trim tiers and body styles:

• 2LT Coupe: $95,595
• 3LT Coupe: $100,245

For driver assistance and safety, basic driver-assist tools come standard, though features like blind-spot monitoring carry an extra cost. Official safety ratings can be reviewed on the NHTSA and IIHS websites.

Interior Cabin, Technology, and Fuel Economy

Inside, the mid-engine C8 remains a strict two-seater. The driver-focused cabin features a 14-inch reconfigurable instrument panel display and an infotainment screen angled toward the driver with support for Google Play Store applications. Upholstery and trim options include leather, real metal accents, and imitation suede. Coupe models feature a removable roof panel that can be stored in the rear cargo compartment.

Storage consists of two trunks—one in the nose and one behind the engine bay—providing a total of 13 cubic feet of cargo volume. In testing conducted by Car and Driver, the compartments successfully held three carry-on-sized suitcases (one up front, two in the rear) or two stacked sets of golf clubs.

Regarding fuel efficiency, the EPA rates the rear-wheel-drive Corvette Stingray at 15 mpg city, 25 mpg highway, and 18 mpg combined. Car and Driver notes this compares favorably to segment competitors like the Ford Mustang Dark Horse, which carries EPA ratings of 14 mpg city and 22 mpg highway combined. EPA ratings for the Grand Sport and hybrid Grand Sport X are expected to be published as data becomes available.
