Rumor Says Chevy Will Debut An Electrified Corvette Grand Sport Soon

Chevrolet’s Corvette lineup could soon change, with talk focusing on the long-rumored return of the Grand Sport—potentially with an electric twist.

Multiple reports have surfaced this week suggesting Chevy is preparing to reintroduce the Grand Sport later this year for the 2027 model year, offering it in two distinct versions, including a hybrid variant that would replace the current Corvette E-Ray.

According to chatter leaking out from GM's annual dealer meetings in Las Vegas, the electrified model—reportedly named Grand Sport X—will combine the automaker's new 6.7-liter LS6 V8 with a front-mounted electric motor. The “X” signals all-wheel-drive, and electrification, similar to the recently introduced ZR1X, which combines a twin-turbo V8 with hybrid assistance to produce a staggering four-figure output.

The hybrid GSX is believed to offer a combined output of around 720 horsepower, placing it above the outgoing E-Ray and even edging past the naturally aspirated Corvette Z06.

If the horsepower figures of GM's electric front axles remain the same, we can do some simple arithmetic to figure out the horsepower figures of GM's long-rumored LS6 V8. If the GSX uses the same 186-horsepower electric motor as the Corvette ZR1X, that means the 6.7L V8 is good for 534 horsepower.

However, if the Grand Sport X keeps the E-Ray's 160-hp electric axle, that means the LS6 actually makes more than 550 ponies.

The current E-Ray pairs GM's 6.2-liter LT2 V8 with an electric front axle to produce 655 horsepower, while the Z06 delivers 670 horsepower from its high-revving flat-plane crank LT6 V8. If the numbers turn out to be truth, the Grand Sport X would snuggle in between the Z06 and more extreme variants like the ZR1 and ZR1X.

Alongside the electrified GSX, Chevrolet is also expected to offer a conventional Grand Sport without hybrid assistance. Historically, the Grand Sport has served as a middle ground in the Corvette lineup, blending track-ready hardware with more accessible, less exotic powertrains.

AutoGuide's Take

If the Grand Sport X does replace the E-Ray, it would be a definite shift in how Chevrolet positions electrification within the Corvette family. Rather than calling out the E-Ray's hybrid tech as a standalone feature, the electrification would augment the automaker's performance narrative. Probably a smart move when your core demographic is relatively old-school in terms of beliefs.

But there are questions about what all of this could functionally mean for the Corvette Z06. If Chevrolet introduces a more powerful hybrid Grand Sport, where does that leave the Z06? Will there need to be an electrified Z06 to maintain the hierarchy, or is there a new engine on deck for the Z06?

For now, nothing is officially confirmed, but all signs point to Chevrolet definitely introducing the Grand Sport name to the C8 Corvette family.
