Chevrolet continues to innovate and raise the bar with its Corvette lineup, unveiling the 2027 Corvette Grand Sport and Grand Sport X. Both models bring exciting updates, including a new 6.7-liter V8 engine, refined aerodynamic design, and cutting-edge performance features. Here, we break down everything you need to know about these new additions to the Corvette family.

A Brief History of the Grand Sport

The Grand Sport name carries a rich history in the Corvette lineage. First introduced in 1963, the Grand Sport began as a limited-edition race car with only five units produced. In later decades, Chevrolet revived the name for the C4 variant’s farewell model, skipped it for the C5 generation, and then redefined it with the C6 and C7 versions as a balance between the base Corvette and the high-performance Z06. The 2027 Grand Sport stays true to this formula but with impressive new advancements.

The 2027 Grand Sport: Power Meets Precision

At the heart of the new Grand Sport is a naturally aspirated 6.7-liter V8 engine, known as the LS6. It’s a nod to Chevy’s storied small-block heritage, marking the sixth generation of this iconic engine series. According to Chevrolet, the LS6 generates 535 horsepower and 520 lb-ft of torque, offering remarkable performance for enthusiasts.

Key Engine Features:

• Increased displacement: Expanded to 6.7 liters from 6.2 liters, powered by a longer stroke (100mm vs. 92mm in the previous LT2 engine).
• High compression ratio: 13:1, up from 11.5 in its predecessor.
• Advanced intake system: Includes a 95mm throttle body (versus 87mm on the LT2) and a tunnel ram intake manifold for more efficient air delivery.
• Redesigned components: Forged pistons and rods, dual oil channels for the crankshaft, and improved cooling around the spark plugs and valves.

This robust engineering ensures the LS6 is primed for exhilarating performance on the road or track.

Handling and Suspension Configurations

The Grand Sport offers three distinct suspension setups, allowing drivers to customize their driving experience:

1. Touring Suspension: The softest option, paired with Michelin Pilot Sport all-season tires, is ideal for daily driving.
2. Sport Performance Package: Features stiffer damping, Michelin Pilot Sport 4S summer tires, and the Z06’s J56 brakes with corrosion resistance.
3. Track Performance Package: Optimized for ultimate track performance with Michelin Pilot Sport Cup 2R tires, carbon ceramic brakes, and the Z06 carbon-fiber aero package. This configuration also features a unique suspension tune and a center-exit exhaust.

Standard across all these setups are Magnetic Ride Control dampers and an electronically controlled limited-slip differential, contributing to the Grand Sport’s sharp handling.

The Grand Sport X: Enter the Hybrid Era

Accompanying the Grand Sport is the all-wheel-drive hybrid Grand Sport X. It combines the LS6 V8 engine at the rear with a 1.9 kWh lithium-ion battery and an electric motor driving the front wheels. This hybrid setup elevates total output to a stunning 721 horsepower, significantly exceeding the 655 horsepower of its predecessor, the E-Ray.

Performance Highlights:

• Power delivery: The hybrid system ensures a 0-60 mph time in the low 2-second range.
• Quarter-mile speed: Capable of completing the quarter-mile in the low 10-second range.
• Suspension options: Available with Touring and Sport Performance setups only, as no dedicated track package has been introduced yet.

Tony Roma, Chevrolet’s executive chief engineer, hinted at more developments for the Grand Sport X, so enthusiasts can expect further updates in the near future.

Shared Features and Pricing Details

Both the Grand Sport and Grand Sport X will be available as either a Targa-roof coupe or a hardtop convertible. While Chevrolet remains tight-lipped about pricing specifics, Roma revealed that the Grand Sport would start below $100,000. The Grand Sport goes on sale in summer 2027, with the Grand Sport X following in the fall.

For their initial model year, both cars will be offered in a Launch Edition featuring a striking blue leather interior with red stitching and accents. These customizable variations add an extra layer of appeal to Chevy’s latest performance lineup.

Practical Engineering Meets Heritage

In addition to their thrilling specs, both Grand Sport models reflect Chevrolet’s commitment to blending performance with practicality. For instance, the LS6 engine now serves as the base engine for the 2027 Stingray and is expected to power select full-size Chevy trucks and SUVs soon. This wide application underscores its versatility and advanced engineering.

Is This the Ultimate Corvette?

Chevrolet has positioned the Grand Sport as a unique offering that balances performance with value, slotting neatly between the base Stingray and the Z06. The addition of hybrid technology in the Grand Sport X further expands the lineup’s appeal, pushing boundaries while honoring the Corvette’s performance heritage. Whether you seek the naturally aspirated thrills of the Grand Sport or the unprecedented power of the Grand Sport X hybrid, 2027 is shaping up to be an exciting year for Corvette enthusiasts.
