2027 Corvette Grand Sport Models Revealed

The Corvette world is buzzing with fresh reports about the upcoming 2027 model year—and for good reason. According to new information, Chevrolet is preparing to introduce not one, but two Corvette Grand Sport models, marking a significant expansion of the C8 lineup. This move not only revives a beloved nameplate but also redefines how the Grand Sport fits into the modern Corvette hierarchy.

With updates to powertrains, naming conventions, and performance capabilities, these new Grand Sport variants could represent one of the most important shifts in recent Corvette history.

Two Corvette Grand Sport Models Confirmed for 2027

For decades, the Grand Sport badge has filled the gap between the base Corvette Stingray and more track-focused variants. That tradition will continue—but with a twist. Instead of a single model, the 2027 Corvette lineup is expected to feature two distinct Grand Sport variants.

Both models will sit squarely between the base Stingray and the high-performance Z06, preserving the classic Corvette lineup structure while offering more variety to buyers. This dual-model approach gives drivers the option to choose between a traditional performance setup and a more advanced electrified experience.

The New 6.7L LS6 V8: A Game-Changer

At the heart of these new Grand Sport models is an all-new 6.7-liter V8 engine, known as the LS6. Built on GM’s latest Gen 6 Small Block architecture, this engine is set to play a central role across the Corvette lineup.

The LS6 will power both the standard Corvette Stingray and the non-hybrid Grand Sport, delivering naturally aspirated performance with improved power, efficiency, and durability. This marks a significant evolution from previous engines, reinforcing Corvette’s commitment to high-performance internal combustion even as electrification enters the picture.

For enthusiasts, this means the classic Corvette experience—high-revving V8 power, rear-wheel drive, and visceral sound—is very much alive.

Corvette Grand Sport vs Grand Sport X: Key Differences

One of the most interesting developments is the introduction of a second model: the Corvette Grand Sport X. This variant is expected to replace the current E-Ray, adopting a new name that better aligns with Corvette’s traditional branding.

The Grand Sport X will feature a hybrid-assisted powertrain, combining the LS6 V8 with a front-mounted electric motor. This setup is expected to produce an impressive 720 horsepower with all-wheel drive capability, making it one of the most powerful Corvettes ever produced.

By comparison, the standard Grand Sport will remain purely gas-powered, using the LS6 engine to drive the rear wheels. This creates a clear distinction between the two models:

• Grand Sport (Non-Hybrid): Naturally aspirated V8, rear-wheel drive
• Grand Sport X (Hybrid): V8 + electric motor, all-wheel drive, 720 horsepower

This split allows Chevrolet to appeal to both purists and tech-forward performance enthusiasts.

Why Rename the E-Ray to Grand Sport X?

The decision to rename the E-Ray to Grand Sport X is more strategic than it might seem. While the E-Ray introduced hybrid performance to the Corvette lineup, its name may have caused confusion among buyers who associated the “E” designation with fully electric vehicles.

By rebranding it under the Grand Sport umbrella, Chevrolet can better communicate the model’s identity as a performance-focused hybrid rather than an EV. The “X” designation adds a modern, high-tech edge while still tying the car to Corvette’s heritage.

This move also simplifies the lineup, making it easier for customers to understand where each model fits.

Performance and Driving Experience

Performance is where these new Grand Sport models are expected to shine.

The non-hybrid Grand Sport will likely deliver a pure, driver-focused experience. With rear-wheel drive and a naturally aspirated V8, it will cater to enthusiasts who value precision, balance, and traditional sports car dynamics.

On the other hand, the Grand Sport X takes things to another level. With 720 horsepower and all-wheel drive, it will offer explosive acceleration and enhanced traction. The addition of the front electric motor not only boosts power but also improves handling and stability, especially in challenging driving conditions.

This combination of technologies could make the Grand Sport X one of the most versatile performance cars in the Corvette lineup.

Expanding the C8 Corvette Lineup

The introduction of two Grand Sport models reflects a broader evolution of the C8 Corvette platform. Chevrolet is clearly looking to expand its offerings, providing more options without straying from the brand’s core identity.

By slotting these models between the Stingray and Z06, Corvette maintains its familiar progression while adding depth to the lineup. Buyers will now have more flexibility to choose a model that fits their driving style and preferences.

This strategy also positions Corvette to compete more effectively in a market where performance and electrification are increasingly intertwined.

What This Means for Corvette Fans

For longtime Corvette fans, the return of the Grand Sport name is exciting in itself—but the addition of a second variant makes it even more compelling.

The standard Grand Sport preserves everything enthusiasts love about the badge: lightweight performance, track capability, and a focus on driving purity. Meanwhile, the Grand Sport X represents the future, blending traditional V8 power with cutting-edge hybrid technology.

Together, these models offer a glimpse into where Corvette is headed—one foot firmly planted in its heritage, and the other stepping into a more advanced, electrified future.

Release Timing and What’s Next

While official confirmation from Chevrolet is still pending, the 2027 model year is shaping up to be a major turning point for the Corvette lineup. With new powertrains, updated naming conventions, and expanded trim options, the upcoming changes are likely to generate significant interest among buyers and collectors alike.

As more details emerge—including official specs, pricing, and release dates—the anticipation surrounding these two Grand Sport models will only continue to grow.

Final Thoughts: A Bold New Direction for Grand Sport

The introduction of two Corvette Grand Sport models for 2027 signals a bold and strategic move by Chevrolet. By offering both a traditional and hybrid variant, the brand is embracing innovation while staying true to its roots.

Whether you’re drawn to the raw simplicity of a naturally aspirated V8 or the cutting-edge performance of a hybrid system, the new Grand Sport lineup promises to deliver something for everyone.

If these reports hold true, the Grand Sport badge isn’t just making a comeback—it’s evolving into something bigger than ever before.
