The 2027 Chevy Corvette Grand Sport has been revealed with a new 6.7-liter V-8 engine.\n\nThe pushrod powertrain sends 535 horsepower and 520 pound-feet of torque through an eight-speed dual-clutch gearbox to the rear wheels.\n\nThe Grand Sport wears the wider body of the Corvette Z06 and offers an optional carbon-fiber aero package and carbon-ceramic brakes.\n\nThe Chevrolet Corvette Grand Sport has returned. After giving us a peek at the new Grand Sport ahead of the 12 Hours of Sebring last weekend, Chevy is now sharing more details about the variant that will slot in between the base Stingray trim and the Corvette Z06. The Corvette Grand Sport will go on sale for the 2027 model year, and the big news is that it ushers in a new engine for Chevy’s iconic sports car.\n\nView Photos\nChevrolet\nYes, the Grand Sport heralds the arrival of a new small-block V-8. Dubbed the LS6, the new eight-cylinder engine displaces 6.7 liters and cranks out 535 horsepower and 520 pound-feet of torque. In the Grand Sport, all of that oomph is directed exclusively to the rear wheels, but Chevy will also offer a Grand Sport X with a hybrid all-wheel-drive setup, which you can read more about here.\n\nFor Sale Near You\nSee all results for new 2027 Chevrolet Corvette Stingray / Grand Sport for sale near 634720\n\nThe 6.7-liter V-8 is hooked up to an eight-speed dual-clutch automatic transmission. We expect it to zip to 60 mph in well under 3.0 seconds, given that a Z51-equipped Stingray, which makes 495 hp and 470 pound-feet of torque from a 6.2-liter V-8, did the same deed in 2.8 ticks in Car and Driver testing.\n\nChevy says this new LS6 engine features hardware focused on delivering usable power. It has a higher 13.0:1 compression ratio to make the engine more responsive, while a larger throttle body and a tunnel-ram intake manifold with high-velocity ports help the engine suck in more air. You’ve likely clocked that this new V-8 is half a liter larger than the V-8 that the C8 Corvette launched with, and Chevy says that increased displacement came from a longer stroke. We’ve detailed more of the engineering that went into the LS6 in a separate story.\n\nView Photos\nChevrolet\nChevy says the LS6 produces more torque than any other naturally aspirated V-8 engine used in a standard Corvette in the model’s 70-plus-year history. The LS6 will be built in Flint, Michigan, and not only will it feature in the Grand Sport and Grand Sport X, but it will also be offered as standard on the base 2027 Corvette Stingray.\n\nThe Grand Sport will also feature several optional packages to increase its capabilities. The car comes standard with Michelin Pilot Sport All Season 4 tires and new brakes that are designed to minimize brake dust and maintain a corrosion-resistant appearance. Magnetic Ride Control, which uses adaptive magnetorheological dampers, is standard.\n\nUpgrading to the Z52 Sport Performance package brings a stiffer suspension, Michelin Pilot Sport 4S summer tires, and the J56 high-performance iron brakes from the Z06. At the top of the range is the Track Performance package, adding sticky Michelin Pilot Sport Cup 2R tires and the J57 carbon-ceramic brakes from the Z06’s Z07 package. It also includes track-focused chassis tuning and a carbon-fiber aerodynamic package, with a front splitter, dive planes, underbody strakes, and a rear wing.\n\nView Photos\nChevrolet\nA quad center exhaust setup is also available, the first time such an exhaust configuration has been found on a pushrod V-8 for the C8 generation, and this option will also be offered on the Stingray. The Performance Traction Management system seen on other General Motors sports cars, which allows you to intricately adjust the traction control intervention, is optional.\n\nVisually, the Grand Sport isn’t too different from the Corvette we already know, wearing the widebody look seen on the Z06 that includes a bigger side air intake. The iconic hash marks painted over the front fenders of past Grand Sports have now been moved to the rear fenders to emphasize the C8’s mid-engined layout. Chevy also brought back Admiral Blue Metallic, a color from the C4 generation, to pair with the center stripe and fender hash marks, offered in a variety of hues. There’s also another new exterior paint color, Pitch Gray Metallic, and the Grand Sport features unique 10-spoke forged aluminum wheels with four available finishes.\n\nView Photos\nChevrolet\nChevy will also offer a Launch Edition for the Grand Sport’s first year on sale, which brings a unique Santorini Blue-Dipped interior with red stitching and accents. A plan view graphic of the Grand Sport is embossed in the headrests and stitched into the floor mats, while the visor over the gauge cluster is wrapped in leather with special red accents that align with the center mark on the steering wheel. A special Grand Sport badge on the steering wheel and a Launch Edition plaque on the central speaker grille round out the upgrades.\n\nThe 2027 Corvette Stingray and Corvette Grand Sport will enter production this summer, with sales likely starting in the second half of the year. Chevy has yet to release pricing for the Grand Sport, but we expect it to start at around $95,000.\n\nIn the electrifying world of high-performance automobiles, few names command as much respect and awe as the Chevrolet Corvette. For decades, this American icon has redefined what’s possible on four wheels, blending raw power with sophisticated engineering. As we enter the 2026 model year, the legend continues to evolve with the much-anticipated return of the Corvette Grand Sport. This isn’t just a new trim; it’s a statement—a bold declaration of intent that places the Grand Sport firmly between the capable Stingray and the track-dominating Z06. Prepare to witness automotive artistry as we delve into the heart of the 2027 Chevy Corvette Grand Sport, a machine forged in the fires of performance innovation.\n\nUnder the iconic long hood of the 2027 Grand Sport beats a heart that beats with American muscle at its finest. Chevrolet has unleashed a new 6.7-liter V-8 engine, codenamed the LS6, a powerhouse that redefines the boundaries of naturally aspirated performance. This isn’t merely an update; it’s a complete rethinking of the Corvette’s powertrain, delivering an astounding 535 horsepower and 520 pound-feet of torque. This surge of power is channeled through a lightning-fast eight-speed dual-clutch automatic transmission, ensuring that every drop of that power is translated into breathtaking acceleration. The result? A 0-to-60 mph time that shaves precious tenths off the clock, placing the Grand Sport in the rarefied air of sub-three-second sprints. It’s a symphony of sound and fury, a V-8 bellow that echoes the Corvette’s racing heritage while embracing the demands of modern performance.\n\nThis new LS6 engine isn’t just about brute force; it’s a testament to engineering excellence. With a compression ratio of 13.0:1, the engine is designed for responsiveness, delivering power exactly when you demand it. A larger throttle body and a tunnel-ram intake manifold with high-velocity ports ensure that this V-8 inhales deeply, maximizing every ounce of air to feed the combustion chambers. The increased displacement, a result of a longer stroke, allows for a broader torque curve, providing exhilarating pull from the moment you touch the accelerator. Chevrolet’s engineers have meticulously crafted this powertrain to deliver usable power, not just peak numbers. This dedication to performance excellence is evident in every rev, every gear change, and every mile devoured on the open road.\n\nBeyond the standard Grand Sport, Chevrolet is pushing the envelope further with the introduction of the Grand Sport X. This variant elevates the performance experience with a hybrid all-wheel-drive system, merging the visceral thrill of the V-8 with the added grip and traction of electric power. This innovative setup allows for even more precise power distribution, enabling the Grand Sport X to master corners with newfound confidence. For those who demand the ultimate in Corvette performance, the Grand Sport X represents the pinnacle of what’s possible when American muscle meets hybrid technology.\n\nThe Grand Sport’s capabilities extend far beyond its potent powertrain. Chevrolet has equipped this masterpiece with a suite of performance enhancements that ensure it lives up to its legendary name. Standard on the Grand Sport are Michelin Pilot Sport All Season 4 tires, providing a perfect balance of grip and durability for year-round performance. The braking system has also received a significant upgrade,
