A fresh wave of leaks tied to closed-door dealer meetings at General Motors is setting the Corvette world buzzing again, and if the details hold, the Chevrolet Corvette lineup could be heading for one of its most significant shakeups yet in 2027.

According to reports first amplified by enthusiast outlet Corvette Blogger, insiders with knowledge of recent dealer presentations in Las Vegas claim that not one but two new variants are in development: a returning Grand Sport and an electrified counterpart tentatively named Grand Sport X.

The information remains unofficial, but it is rooted in the kind of dealer-level briefings that have historically previewed future Corvette programs with surprising accuracy.

A Familiar Formula, Revived

At the center of the story is the revival of the Grand Sport badge, a name that has traditionally occupied the sweet spot between base and track-focused Corvettes.

In prior generations, the formula paired the standard engine with more aggressive chassis hardware borrowed from higher trims. That approach appears set to continue, albeit with a modern twist shaped by both increased performance expectations and electrification.

The rumored 2027 Grand Sport is expected to adopt a new 6.7-liter LS6 V8 engine, part of a next-generation small-block family reportedly being developed across GM’s portfolio.

Output is said to land in the 530 to 550 horsepower range, a meaningful bump over today’s Stingray and enough to reinforce the model’s role as a performance bridge beneath the Z06.

Chassis upgrades are also anticipated. As with past Grand Sport models, enhancements could include wider bodywork, upgraded suspension tuning, improved cooling, and more aggressive tires. The goal is familiar: deliver track-ready composure without the higher-revving, more specialized engine of the Z06.

An Electrified Twist: The Grand Sport X

But the bigger headline is the second model reportedly in development. Dubbed Grand Sport X, this variant is said to pair the new LS6 V8 with a front-mounted electric motor, creating an all-wheel-drive hybrid configuration.

That setup would mirror the architecture seen in the current E-Ray, but with significantly more power.

Early figures suggest a combined output of around 720 horsepower, which would mark a substantial leap over the E-Ray’s 655 horsepower. Some speculation even points to the use of a more powerful front motor derived from the ZR1X, potentially giving the Grand Sport X both improved traction and sharper acceleration.

If accurate, the Grand Sport X would not simply complement the current lineup. It could replace the E-Ray entirely.

Multiple reports tied to the dealer meeting leaks indicate that GM is considering phasing out the hybrid model in favor of this more performance-focused successor, effectively repositioning electrification as a tool for outright speed rather than everyday usability.

This potential shift reflects a broader evolution within the Corvette family. The C8 generation has already expanded the nameplate into a full performance spectrum that stretches from the entry-level Stingray to the extreme ZR1X.

Adding two Grand Sport variants would further densify that lineup, giving buyers a wider range of choices while reinforcing the brand’s performance-first identity.

Unanswered Questions and What’s Next

There are still unanswered questions. Pricing remains speculative, and it is unclear how GM would position the Grand Sport X relative to the Z06 and higher-end models. Some reports suggest it could even rival or exceed the Z06 in output, which would complicate the traditional hierarchy.

For now, everything hinges on confirmation from GM. Until then, these leaks remain just that. But if history is any guide, dealer meeting whispers often signal what is already well underway behind the scenes.

And in this case, they point to a future where the Corvette continues to evolve by blending heritage, horsepower, and hybrid technology into something entirely new.
