Adding a new dimension to the Corvette lineup is the Grand Sport X, a hybrid variant that takes performance to an entirely new level. By incorporating an 186-hp electric motor between the front wheels and a 1.9-kWh lithium-ion battery, the Grand Sport X transforms the rear-wheel-drive Grand Sport into an all-wheel-drive hybrid. This powertrain combination yields a staggering 721 horsepower, a 66-hp increase over the outgoing Corvette E-Ray. With this level of power, the Grand Sport X is projected to achieve 0-60 mph times in the low two-second range, with quarter-mile runs in the low 10s, placing it firmly in the realm of hypercar performance.
The LS6 engine itself is a testament to Chevrolet’s commitment to engineering excellence. With a compression ratio of 13.0:1, up from 11.5:1, the engine achieves greater thermal efficiency. The addition of port fuel injection helps to mitigate particulate emissions, addressing growing environmental concerns. Furthermore, the pistons and connecting rods have been forged to withstand the increased stresses of this high-performance powerplant, ensuring durability and longevity for enthusiasts who may choose to further tune the engine for even greater power output.
The auditory experience of the LS6 is equally impressive. At startup, the engine emits a fierce bark that quickly settles into a deep burble at idle, culminating in a feral snarl as the revs climb. Chevrolet offers two exhaust options for the LS6: a standard system with four tips split between the left and right sides, and an optional system that consolidates all four tips in the center of the car. Both systems feature active valves to control the engine note and volume, though engineers note a discernible difference in sound between the two. The center-exit exhaust, in particular, is highly recommended for those seeking the most immersive auditory experience.
The transmission choices for the 2027 Grand Sport lineup reflect Chevrolet’s dedication to performance. The Tremec eight-speed dual-clutch transmission remains the sole option, ensuring rapid gear changes and seamless power delivery. A new 5.56:1 final drive ratio has been implemented, providing more aggressive gearing for enhanced acceleration. This more aggressive ratio will also be available on the 2027 Corvette Stingray with the optional Z51 package, which previously utilized a 5.13:1 ratio. This change in gearing underscores Chevrolet’s focus on optimizing performance across its Corvette lineup.
The handling characteristics of the Grand Sport are a direct result of its meticulous engineering and component selection. The standard touring setup is paired with Michelin Pilot Sport All Season tires, offering a comfortable ride balanced with capable handling. For those seeking a more performance-oriented experience, the Sport Performance package introduces a stiffer suspension and Michelin Pilot Sport 4S summer tires, complemented by the Z06’s J56 brakes. This package represents a significant upgrade in handling prowess, making it an ideal choice for spirited driving on winding roads.
For the most discerning track enthusiasts, the Track Performance package offers the ultimate expression of Corvette performance. Building on the Z06’s Z07 upgrade, this package includes Michelin Pilot Sport Cup 2 R tires, carbon-ceramic brakes, a carbon-fiber wing and dive planes, a unique chassis tune, and the aforementioned center-exit exhaust. This comprehensive package transforms the Grand Sport into a track-ready machine, capable of competing with the world’s best sports cars. The standard forged wheels are available in four different finishes, with carbon-fiber wheels offered as an option on cars equipped with carbon-ceramic brakes, further enhancing the vehicle’s exclusivity and performance credentials.
The Grand Sport X, with its hybrid powertrain and all-wheel-drive system, commands an even higher level of performance engineering. Carbon-ceramic brakes come standard on the Grand Sport X, providing the necessary stopping power to manage its formidable 721 horsepower. Chevrolet offers two suspension configurations for the X: a touring setup on all-season tires for a balance of comfort and performance, and a Performance suspension tune with summer tires for those seeking ultimate handling. Notably, there is no Track package or carbon-fiber aero kit available for the Grand Sport X, a decision that Chevrolet engineers suggest may be subject to change in the future, leaving enthusiasts with a tantalizing glimpse of what may come.
Visually, the Grand Sport and Grand Sport X maintain the signature Corvette aesthetic while introducing subtle yet distinctive design elements.
