2027 C8 Corvette Grand Sport and Grand Sport X: What to Know

Chevrolet brought the Grand Sport name back to the C8 Corvette lineup, and this is not just a badge package. The 2027 Grand Sport and Grand Sport X introduce the next-generation LS6 6.7L V8, a wide-body setup, new performance packages, and a clear split between rear-wheel-drive purity and hybrid all-wheel-drive speed.

This article is based on Chevrolet's official Grand Sport page and the full ZK's Garage walkthrough video, where I went through the specs, pricing, configurator, trim differences, and the Grand Sport X question.

Grand Sport vs. Grand Sport X

The standard Grand Sport is the purer driver's car: rear-wheel drive, naturally aspirated V8, wide body, and the classic Grand Sport formula of Stingray power with more serious performance hardware.

The Grand Sport X adds an electrified front axle. That gives the car all-wheel-drive capability and a much bigger combined output. Chevrolet lists the Grand Sport X at 721 combined horsepower, with the front electric drive unit sending 145 lb-ft of torque to the front wheels.

That is the core decision for buyers: do you want the simpler, rear-wheel-drive Grand Sport, or do you want the hybrid AWD Grand Sport X with the biggest performance jump?

The New LS6 6.7L V8

The biggest mechanical story is the LS6. Chevrolet says the new naturally aspirated 6.7L V8 makes 535 horsepower and 520 lb-ft of torque. It also uses a 13.0:1 compression ratio, the highest ever for a Corvette V8, and a new continuously variable oil pump.

The LS6 matters because it is not limited to Grand Sport. Chevrolet also says it will be available on the upcoming 2027 Corvette Stingray, meaning the base C8 lineup gets a major engine change too.

For current Stingray owners, that is a big deal. The LT2 has been great, but the LS6 pushes the standard Corvette powertrain into a new era.

Wide Body, Design, and Heritage

The Grand Sport formula has always been about mixing the base Corvette powertrain with more aggressive chassis and visual cues. The C8 version follows that idea with a bold wide-body look and Grand Sport-specific identity.

The rear-quarter hash marks nod to Grand Sport heritage, but the placement also makes sense on the C8 because the engine is behind the driver. It is a small detail, but it helps connect the historical Grand Sport idea to the mid-engine car.

Chevrolet also revived Admiral Blue Metallic and offers an inaugural interior package with Santorini Blue details, special stitching, headrest logos, and a waterfall badge plaque for debut models.

Performance Packages: Z52 Sport and Z52 Track

The Grand Sport lineup also changes the package conversation. Instead of thinking only in terms of Z51, Chevrolet lists Z52 Sport and Z52 Track performance packages for the Grand Sport.

Z52 Sport is the more street-focused performance setup, with upgraded braking and grip. Z52 Track goes harder with equipment like carbon ceramic brakes, Michelin Pilot Sport Cup 2R tires, quad center exhaust, and carbon-fiber aero.

That gives buyers a more obvious split: street-focused Grand Sport, serious track-package Grand Sport, or Grand Sport X if you want the hybrid AWD performance setup.

Trims and Interior Choices

The familiar 1LT, 2LT, and 3LT structure remains important. 1LT is the entry point. 2LT adds major daily-driving comfort and tech features. 3LT adds the more premium interior treatment.

As a C8 owner, I still think buyers should take 2LT seriously. The visibility, comfort, audio, and daily-use features matter more once you actually live with the car. My C8 trim guide breaks down why.

Which One Would I Pick?

In the video, I kept coming back to the Grand Sport X. The standard Grand Sport is the cleaner purist choice, but 721 combined horsepower, all-wheel-drive traction, and the LS6 V8 is a wild package.

That said, the regular Grand Sport may be the sweet spot for a lot of owners. It keeps the naturally aspirated rear-wheel-drive character while adding the wide-body look and serious performance hardware.

Final Verdict

The 2027 Grand Sport lineup is a major C8 moment. The standard Grand Sport gives Corvette buyers the wide-body, naturally aspirated driver's car many people wanted. The Grand Sport X turns that formula into a hybrid AWD performance monster.

Either way, the LS6 changes the conversation. If you are shopping new, this is now one of the most important C8 Corvette variants to understand before you order.
