2027 Chevrolet Corvette Grand Sport and Grand Sport X: The Ultimate Sweet Spot of Performance and Value
For over a decade, the Chevrolet Corvette team has redefined what a world-class sports car can be, pushing boundaries with vehicles like the 8,600-rpm Z06, the 1,064-hp ZR1, and the hypercar-slaying, 1,250-hp ZR1X. Just as the first deliveries of the ZR1X are beginning, Chevrolet has pulled the wraps off not one, but two new additions to the C8 Corvette lineup for 2027: the Grand Sport and the Grand Sport X. These new models aim to deliver the thrilling performance and handling characteristics of the Z06 but at a more attainable price point, slotting perfectly between the base Stingray and the top-tier Z06.
At the heart of both the 2027 Chevrolet Corvette Grand Sport and Grand Sport X lies a brand-new engine that represents a significant milestone for the Corvette legacy: the LS6 small-block V-8. This 6.7-liter naturally aspirated powerhouse produces a formidable 535 horsepower and 520 lb-ft of torque, offering a perfect blend of traditional V-8 character and modern performance engineering. By combining this potent new engine with the wider body and track-ready components from the Z06, Chevrolet has created a recipe that promises to deliver an exceptional driving experience. The Grand Sport has long been regarded as the enthusiast’s choice, balancing track capability with everyday usability, and the 2027 models appear poised to uphold and even elevate this reputation.
The performance-oriented Grand Sport has always been a favorite among Corvette aficionados who appreciate a car that excels on the track while still being enjoyable on the street. For 2027, Chevrolet is building on this legacy by pairing the new 6.7-liter V-8 with the Z06’s wider bodywork and several of its performance-enhancing options. This formula has proven successful in the past, and given how every other iteration of the C8 Corvette drives, there’s every reason to believe the Grand Sport will be a truly special sports car. Adding to the excitement, the first-ever Grand Sport X takes this concept even further by incorporating elements from the 1,250-hp ZR1X. This new model adds a 186-hp electric motor at the front and a 1.9-kWh lithium-ion battery in the tunnel between the driver and passenger, transforming the rear-drive Grand Sport into an all-wheel-drive hybrid. With the combined output of the gas engine and electric motor, the Grand Sport X produces a staggering 721 horsepower, a 66-hp increase over the 655-hp Corvette E-Ray it replaces. Chevrolet predicts 0-60 mph times in the low two-second range and quarter-mile runs in the low 10s, positioning the Grand Sport X as a formidable force in the world of high-performance hybrids.
Chevrolet’s Small-Block V-8 Grows Bigger for 2027
Chevrolet has named the Corvette’s new V-8 the LS6, a nod to the fact that this is only the sixth generation of the legendary small-block engine family. For those who cherish the naturally aspirated V-8, this new powerplant represents a significant moment in automotive history. The LS6 is the modern embodiment of the adage, “There’s no replacement for displacement.” Chevrolet engineers have increased the Corvette’s engine displacement from 6.2 to 6.7 liters by lengthening the stroke from 92 to 100 millimeters. While the bore and the 4.4-inch bore spacing remain consistent with the small-block’s signature design, the longer stroke has resulted in a substantial increase in torque, even more so than the horsepower gains. Compared to the outgoing LT2 V-8 in the Corvette Stingray, the LS6 delivers an impressive 40 more horsepower and 50 more lb-ft of torque. It produces more torque than any other naturally aspirated V-8 currently in production, with a peak output of 520 lb-ft arriving earlier in the rev range at 4,600 rpm.
The new engine operates with a higher compression ratio of 13.0:1, up from the previous 11.5:1. To improve particulate emissions, port fuel injection has been integrated into the design. Furthermore, to withstand the increased stresses of the LS6, both the pistons and connecting rods are now forged, which will be a welcome development for tuners and enthusiasts looking to extract even more performance from this new small-block. The engine unleashes a fierce bark at startup, settles into a deep burble at idle, and delivers a feral snarl as the revs climb. Chevrolet will offer two exhaust options for the LS6. The standard setup splits the four exhaust tips between the left and right sides of the car, while an optional system clusters all four tips in the center. Both systems feature active valves to control the engine note and volume, and while there’s no difference in power output, Chevrolet engineers report a noticeable difference in sound, with the center exhaust producing a more aggressive tone. For those seeking the ultimate auditory experience, the center-exit exhaust appears to be the preferred choice.
What Makes a Grand Sport a Grand Sport in 2027?
The 2027 Chevrolet Corvette Grand Sport and Grand Sport X will be available in two distinct body styles: the traditional targa-topped coupe and a folding-hardtop convertible. Both models come standard with MagneRide dampers and an electronically controlled limited-slip differential, providing a solid foundation for exceptional handling. Power is routed through the Tremec eight-speed dual-clutch transmission, which features a new 5.56:1 final drive ratio. This more aggressive gearing will enhance acceleration at the expense of fuel economy, and it will also be offered on the 2027 Corvette Stingray with the optional Z51 package, which previously used a 5.13:1 ratio.
The rear-drive Grand Sport will be available with three distinct chassis setups to cater to different driving preferences. The standard touring setup offers the softest ride, paired with Michelin Pilot Sport All Season tires for comfortable cruising. Moving up the performance ladder, the Sport Performance package features a stiffer suspension and Michelin Pilot Sport 4S summer tires, along with the Z06’s J56 brakes, which are treated with a high-temperature ferritic nitro carburizing process for enhanced corrosion resistance. For those seeking the ultimate track-day experience, the Track Performance package mirrors the Z06’s Z07 upgrade, including Michelin Pilot Sport Cup 2 R tires, carbon-ceramic brakes, a carbon-fiber rear wing and dive planes, a unique chassis tune, and a center-exit exhaust. The standard forged wheels are available in four different finishes, and carbon-fiber wheels can be optioned on cars equipped with carbon-ceramic brakes.
The Grand Sport X takes the performance-oriented equipment even further, featuring carbon-ceramic brakes as standard to manage its formidable power. Similar to the Grand Sport, Chevrolet will offer a touring suspension on all-season tires or a Performance suspension tune with summer tires. However, there is no Track package or carbon-fiber aero kit for the X at launch. When asked about the absence of these features, executive chief engineer Tony Roma simply advised to stay tuned, hinting at potential future developments. As with all Grand Sport models, the signature hash stripes adorn the rear fenders, though this year they are exclusively located at the rear.
Is This the Sweet Spot of Performance and Value in 2027?
The 2027 Chevrolet Corvette Grand Sport and Grand Sport X are set to hit dealerships this summer, with the Grand Sport X following in the fall. Both versions will be available in a special Launch Edition for the initial model year, featuring a striking blue-dipped leather interior with red stitching and accents, showcasing the premium materials and attention to detail that define the Corvette brand.
While Chevrolet has yet to announce official pricing, Tony Roma revealed that the Grand Sport will start under $100,000. This positions the Grand Sport as an exceptional value proposition in the high-performance sports car market, offering a level of performance and features that are virtually unmatched at this price point. Given the pricing structure of previous C8 generations and the performance capabilities of the Grand Sport and Grand Sport X, we can confidently say that these new models represent the best way to experience the most special aspects of the Corvette lineup without the premium price tag of the Z06, ZR1, or ZR1X. The combination of the new LS6 V-8, Z06-derived components, and a range of performance packages makes the 2027 Chevrolet Corvette Grand Sport and Grand Sport X a compelling proposition for driving enthusiasts seeking the ultimate blend of performance, handling, and value.
