Chevy's 2027 Corvette Grand Sport Drops the E-Ray Name and Doubles Down on V8 Hybrid Power

General Motors surprised attendees at the 12 Hours of Sebring this past weekend by rolling out the 2027 Chevrolet Corvette Grand Sport. Legendary racing team owner Roger Penske was on hand to drive the new car, a fitting tribute to his class victory in a C2 Grand Sport at the exact same track back in 1964. The pre-production car wore the iconic Admiral Blue paint, a central white racing stripe, and red hash marks shifted to the rear fenders to highlight the modern mid-engine layout. Beneath that heritage styling lies a significant shift in how Chevrolet approaches its performance future. Amid an industry rushing toward pure battery power, GM is investing heavily in a brand new internal combustion engine and pairing it with hybrid technology to streamline its lineup.

The heart of the new Grand Sport is a heavily rumored 6.7-liter naturally aspirated V8 known internally as the LS6. This engine represents the sixth generation of the legendary GM small-block architecture, proving that the automaker still sees a viable future for high-displacement combustion. Chevrolet is prioritizing classic natural aspiration and modern engine management over the prevailing industry trend of smaller, turbocharged powerplants. The regular Grand Sport will send an estimated 550 horsepower exclusively to the rear wheels. It slots perfectly into the traditional sweet spot between the 495-horsepower base Stingray and the 670-horsepower track-focused Z06. Buyers who want compliant daily drivability paired with upgraded brakes, track-ready cooling systems, and wide-body aerodynamics have always gravitated to this specific trim level.

A second model will debut alongside the standard car to address a glaring branding problem. When Chevrolet introduced the current Corvette E-Ray, the name led many casual consumers to assume it was a fully electric vehicle. Dealerships had to constantly explain that the car actually housed a 6.2-liter V8 behind the driver alongside its battery pack. Chevrolet is reportedly solving this showroom confusion by retiring the E-Ray nameplate entirely and replacing it with a new hybrid model called the Grand Sport X.

The Grand Sport X takes the new 6.7-liter LS6 V8 and pairs it with a front-mounted electric motor. Drive, an Australian automotive publication, reported that leaks from a recent Las Vegas dealer meeting suggest this combination will produce roughly 720 horsepower. The electrified front axle is designed specifically to provide instant torque out of tight corners and massive all-wheel-drive traction off the line. This specific application of electrification is engineered to maximize grip and outright acceleration.

The electric motor simply handles the front wheels while the V8 does the heavy lifting out back.

For a prospective buyer, this dual-model approach clarifies the ownership experience. The standard Grand Sport offers the traditional, lightweight, rear-wheel-drive dynamics that purists expect from the badge. The Grand Sport X provides all-weather grip and electrified acceleration without the charging logistics or range anxiety of a pure EV. Owners get the thunderous exhaust note of a massive V8, supplemented by the kind of off-the-line launch capabilities usually reserved for battery electric vehicles. You will no longer have to explain to your neighbors that your hybrid supercar still requires premium unleaded fuel at the gas station.

Owning a performance hybrid does introduce a unique set of variables to your garage. Traditional Corvette buyers are used to straightforward oil changes and readily available parts for their small-block engines. The Grand Sport X will require technicians certified to work on high-voltage systems, which can limit your options for independent repair shops down the road. Insurance premiums also tend to reflect the complexity of replacing a front electric motor and an onboard battery pack in the event of a front-end collision. The practical trade-off is a highly capable sports car that can silently creep out of your apartment complex or suburban driveway on electric power early in the morning before the V8 roars to life on the open highway.

Chevrolet has scheduled the official reveal and full specification release for March 26. Until then, the preview lap at Sebring sends a clear message about the current automotive landscape. Automakers are finding highly practical ways to blend legacy internal combustion with modern electrification, proving that a battery and a V8 can share the same chassis to benefit the everyday driver.
