The Chevrolet Corvette Grand Sport is a high-performance sports car combining the Stingray’s engine with the Z06’s wide body and track hardware. The 2027 model uses the 535 hp LS6 6.7L V8 and an 8-speed dual-clutch transmission. It targets buyers who want genuine track capability at a price below the Z06.
The Grand Sport uses Z06-derived aerodynamics and Magnetic Selective Ride Control 4.0 to deliver exceptional track behavior. The 2027 model’s 13.0:1 compression ratio is the highest ever in a Corvette V8. Motor Trend’s long-term test confirms the car handles road and circuit use equally well.
This review covers what the Grand Sport is, how it performs, what real-world tests reveal, and whether it justifies the price premium over the Stingray. Our experts at Eat Proteins have synthesized long-term test data from Motor Trend, Car and Driver, and CarPro so buyers can make a confident purchase decision.
What Is the Chevrolet Corvette Grand Sport?
The Chevrolet Corvette Grand Sport combines Stingray power with the Z06’s wide body and track-focused features in a single performance package. The 2027 model runs a 535 hp LS6 6.7L V8 and an 8-speed dual-clutch transmission. Chevrolet targets buyers who want more capability than a Stingray delivers without paying full Z06 money.
Here’s the thing: the Grand Sport name carries serious weight. Chevrolet first used it on the legendary 1963 Corvette, one of the rarest race cars in the marque’s history. The nameplate returned in 1996, again from 2010 to 2014, then from 2017 to 2019, and now for the 2027 model year.
Grand Sport Generations:
- 1963 — Original race-only prototype, one of the rarest Corvettes ever built
- 1996 — First production Grand Sport, limited run coupe and convertible
- 2010 to 2014 — C6 generation, wide body with Z06 suspension
- 2017 to 2019 — C7 generation, praised as ‘happy medium’ by Motor Trend
- 2027 — C8 generation, 535 hp LS6 V8 with Z06-derived chassis
Bottom line: the Grand Sport sits between the Stingray and Z06 in the Corvette hierarchy. Motor Trend called the 2017 version ‘a true happy medium.’ That description still applies to the 2027 generation.
How Does the Corvette Grand Sport Differ from the Stingray?
The Corvette Grand Sport uses the Z06-derived wide body to deliver improved aerodynamics and cornering stability that the standard Stingray body can’t match. The wider tracks front and rear allow larger contact patches and more aggressive suspension geometry. This hardware difference makes the two cars feel distinctly different at speed.
The engine gap? It’s significant. Grand Sport runs the next-generation LS6 6.7L V8 rated at 535 hp and 520 lb-ft (705 Nm) of torque. The Stingray uses the LT2 6.2L V8. The Grand Sport’s 13.0:1 compression ratio is the highest ever fitted to a Corvette V8.
Track hardware also separates the two. Grand Sport adds Magnetic Selective Ride Control 4.0, an integrated rear spoiler, and access to the Z52 Track Performance Package. Stingray buyers don’t get these options as standard features.
Grand Sport vs Stingray Comparison:
| Feature | Grand Sport | Stingray |
| Engine | LS6 6.7L V8, 535 hp | LT2 6.2L V8 |
| Body | Z06 wide body | Standard body |
| Suspension | Magnetic Ride Control 4.0 | Standard suspension |
| Track Package | Z52 available | Not available |
| Rear Spoiler | Integrated | Standard |
What Are the Key Specs of the 2027 Corvette Grand Sport?
The 2027 Corvette Grand Sport produces 535 hp and 520 lb-ft (705 Nm) of torque from a 6.7L LS6 V8 with a 100 mm stroke and the highest compression ratio ever in a production Corvette V8. The 8-speed dual-clutch transmission routes that power to the rear wheels. An AWD hybrid variant called the Grand Sport X is also available.
And here is the best part: the spec sheet backs up every claim. Displacement is 6.7 liters. Stroke measures 100 mm (3.94 inches). Compression ratio sits at 13.0:1. These figures combine for linear, authoritative power delivery across the rev range.
2027 Grand Sport Key Specifications:
| Specification | Value |
| Engine | LS6 6.7L V8 |
| Horsepower | 535 hp |
| Torque | 520 lb-ft (705 Nm) |
| Transmission | 8-speed dual-clutch |
| Compression Ratio | 13.0:1 |
| Stroke | 100 mm (3.94 in) |
The Launch Edition adds exclusive content for inaugural buyers. Santorini Blue Dipped interior, custom stitching, embossed headrest logos, and a waterfall badge interior plaque are all exclusive to the first-year debut models. Availability is limited.
What Engine Does the Corvette Grand Sport Have?
The Corvette Grand Sport uses the next-generation LS6 6.7L V8 engine, which Corvette Chief Engineer Josh Holder called the most powerful standard engine ever offered in a Corvette. Output is 535 hp and 520 lb-ft (705 Nm) of torque. The engine responds with precision and authority to every throttle input.
In fact, the LS6 designation is entirely new for this generation. Displacement grows to 6.7 liters with a 100 mm (3.94 inch) stroke. Compression rises to 13.0:1, the highest ratio ever in a Corvette V8. These design choices produce immediate, linear power rather than a peaky, rev-dependent curve.
To be clear: engineering intent here is track performance without sacrifice. The Grand Sport delivers 535 hp as standard equipment, not as an option. Chevrolet engineers this engine to complement the Z06-derived chassis, making the powertrain and body work as a unified performance system.
How Fast Is the Corvette Grand Sport 0-60?
The Corvette Grand Sport is expected to reach 60 mph from rest in approximately 3.5 seconds or less based on the 535 hp output and dual-clutch transmission, improving on the 2019 model’s Car and Driver-tested time of approximately 3.7 seconds. The 2027 model’s additional power and updated transmission point to a faster run.
Historical data provides a useful baseline. Previous Grand Sport generations turned quarter-mile times in the 11-second range at approximately 120 mph (193 km/h). The 2027 model’s 535 hp rating suggests meaningful improvement in both 0-60 and quarter-mile figures. So what does that mean for you? It means the Grand Sport is genuinely fast for its segment, not just on paper.
What Transmission Does the Corvette Grand Sport Use?
The Corvette Grand Sport uses an 8-speed dual-clutch transmission that delivers near-instantaneous gear changes with no torque converter lag. The dual-clutch design pre-selects the next gear while the current one is engaged. This process produces shift times measured in milliseconds rather than tenths of a second.
Driver control remains accessible. Paddle shifters allow manual gear selection at any time. The reason is simple: the transmission logic defaults to automatic mode for casual driving and holds gears longer under aggressive inputs. The DCT setup complements the linear power delivery of the LS6 V8 for a cohesive driving experience.
What Are the Performance Features of the Corvette Grand Sport?
The Corvette Grand Sport combines the Stingray’s engine architecture with the Z06’s wide body, Magnetic Selective Ride Control 4.0, integrated rear spoiler, and access to the Z52 Track Performance Package as a unified performance system. No other Corvette trim delivers this specific combination at the Grand Sport’s price point. The package is designed for buyers who drive on both road and circuit.
Aerodynamics are a core differentiator. The Z06-derived wide body generates more downforce than the Stingray body. The integrated rear spoiler manages airflow at high speed. Wider front and rear tracks improve lateral stability in corners.
Standard Performance Features:
- LS6 6.7L V8 engine with 535 hp and 520 lb-ft torque
- Z06-derived wide body for downforce and aerodynamic stability
- Magnetic Selective Ride Control 4.0 adaptive suspension
- Integrated rear spoiler for high-speed airflow management
- 8-speed dual-clutch transmission with paddle shifters
The good news? The street-to-track balance is deliberate. Motor Trend described the 2017 Grand Sport as ‘a true happy medium’ after extensive real-world and track testing. The 2027 model builds on that foundation with more power and updated suspension technology.
Does the Corvette Grand Sport Handle Well on the Track?
Yes. The Corvette Grand Sport delivers exceptional track behavior confirmed by Motor Trend’s long-term test and first drive, with the 2017 model earning ‘Back to the Track’ and ‘First Test’ coverage from the publication. The wide body provides the cornering envelope. The suspension delivers the precision to use it.
Magnetic Selective Ride Control 4.0 is the key enabler. The system adjusts damping in real time based on road surface and driver inputs. Response occurs in milliseconds. The result is a car that stays flat through corners without compromising straight-line ride quality.
And it gets better: the Z52 Track Performance Package extends capability further. It adds track-proven stopping power, sharper throttle response, and precise cornering characteristics. Buyers who attend track days should spec the Z52 from the factory.
What Suspension and Brake Upgrades Does the Grand Sport Include?
The Corvette Grand Sport comes standard with Magnetic Selective Ride Control 4.0, which continuously varies damping in real time to deliver both road comfort and track-level cornering precision. The system reads road and vehicle inputs and adjusts each corner independently. No driver input is required.
The Z52 Track Performance Package adds dedicated brake hardware. Track-proven stopping power, larger rotors, and performance brake compounds are part of the package. This upgrade is aimed at buyers who use the car at motorsport facilities and need consistent braking performance over multiple laps.
Pay attention to this: wheel fitment deserves real consideration. Motor Trend’s long-term test documented ‘Wheel Woes’ as a specific finding during extended testing of the 2017 Grand Sport. Buyers planning high-mileage use or frequent track sessions should research tire wear patterns before finalizing specifications.
What Does the Corvette Grand Sport Interior Look Like?
The Corvette Grand Sport interior is built around a driver-focused command center with multiple leather-appointed and sueded seating surfaces, creating a cockpit that balances performance ergonomics with buyer customization. The layout places controls within reach of the driver without distraction. The wide body exterior carries into cabin proportions.
The Launch Edition elevates the interior significantly. Custom stitching, a Santorini Blue Dipped interior finish, embossed headrest logos, and a waterfall badge interior plaque are exclusive to inaugural 2027 debut models. This package isn’t available on later production builds.
Launch Edition Interior Exclusives:
- Custom stitching throughout the cabin
- Santorini Blue Dipped interior finish
- Embossed headrest logos
- Waterfall badge interior plaque
Standard buyers have meaningful choices. Multiple leather and sueded surface combinations are available through the Corvette configurator. Color, trim level, and seat material selections allow significant personalization without requiring the Launch Edition premium.
What Technology and Infotainment Does the Grand Sport Offer?
The Corvette Grand Sport features an 8-inch driver information display and a 12-inch center touchscreen on the modern Corvette platform, evaluated by Car and Driver as a distinct infotainment and connectivity category in their comprehensive review process. The system integrates navigation, vehicle performance data, and connectivity in a single interface.
Driver assistance technology is part of the standard evaluation. Car and Driver lists safety and driver-assistance features as a dedicated review category for the 2027 Corvette Grand Sport. The platform supports an available active safety suite appropriate for a performance sports car.
What Do Corvette Grand Sport Reviews Say?
Corvette Grand Sport reviews across Motor Trend, Car and Driver, and CarPro consistently describe the model as the best-value performance option in the Corvette family, praised for delivering Z06-level hardware at a lower price point. No publication has published a negative long-term verdict on the Grand Sport nameplate across any of its model year runs.
The reason is simple: Motor Trend conducted a full long-term test on the 2017 Grand Sport. The test logged real-world reliability and performance data over an extended period. The resulting coverage included a first test, a long-term update, and a track session section — all of which contributed to a favorable final assessment.
What Are the Pros of the Corvette Grand Sport?
The Corvette Grand Sport’s primary strength is its value proposition: Z06-derived wide body construction and track hardware at a price below the Z06, powered by a 535 hp engine that significantly outperforms previous Grand Sport generations. Buyers get genuine performance equipment without paying the full Z06 premium.
Pros:
- Z06-spec wide body and track hardware at a lower price than the Z06
- 535 hp LS6 V8 is the most powerful standard Corvette engine ever offered
- Magnetic Selective Ride Control 4.0 enables road and track dual-use
- Grand Sport heritage connects to the iconic 1963 original
- Z52 Track Performance Package available for dedicated circuit drivers
Heritage value adds a dimension competitors can’t match. The Grand Sport name connects buyers to the 1963 original, one of the rarest Corvettes ever built. That lineage is tangible at Corvette events and at auction, where historic Grand Sport provenance commands a premium.
What Are the Common Complaints About the Grand Sport?
The most documented complaint about the Corvette Grand Sport is wheel and tire wear, flagged directly by Motor Trend during the 2017 long-term test under the heading ‘Wheel Woes.’ The wide body and performance rubber combination accelerates wear under aggressive use. Buyers should budget for tire replacements more frequently than on a standard Corvette.
Cons:
- Tire wear accelerates under aggressive use on the wide body setup
- Price premium over Stingray may not suit buyers who stay on public roads
- Launch Edition availability is limited to inaugural 2027 debut models
- High demand creates potential for dealer markups above MSRP
Availability presents a short-term challenge. The 2027 Launch Edition is limited to inaugural debut models. High demand for the new-generation Grand Sport creates allocation pressure at dealerships. Buyers who want specific configurations may face wait times or markups above MSRP.
How Much Does the Chevrolet Corvette Grand Sport Cost?
The 2027 Corvette Grand Sport is priced between the Stingray and Z06 in the Corvette lineup, with Car and Driver listing pricing and trim selection as a dedicated evaluation category in their comprehensive review of the model. Exact MSRP for the 2027 model year wasn’t published in available sources at time of writing. The positioning is consistent with prior Grand Sport generations.
Optional packages add meaningfully to the base price. The Z52 Track Performance Package and Launch Edition each carry separate price premiums. Interior configurations with leather-appointed and sueded surfaces also affect the final build total.
Is the Corvette Grand Sport Worth the Price?
Yes. The Corvette Grand Sport delivers Z06-derived wide body construction and track-focused hardware at a price point that reviewers consistently identify as the most compelling value in the Corvette lineup. The 535 hp engine alone justifies the premium over the Stingray for performance-oriented buyers.
Competitor context strengthens the case. Car and Driver benchmarks the 2027 Grand Sport against the Lotus Emira and Nissan Z. The Grand Sport’s 535 hp significantly exceeds both alternatives. Price-per-horsepower and price-per-track-capability favor the Chevrolet decisively.
Grand Sport vs Competitors at a Glance:
