Callaway Cars introduces a supercharger kit for the Corvette E-Ray, boosting power to 847 horsepower while maintaining factory reliability.
The already-powerful Chevrolet Corvette E-Ray has received a massive performance upgrade courtesy of renowned tuner Callaway Cars, pushing the hybrid Corvette’s horsepower rating to an eye-popping 847.

Unveiled this week, Callaway's performance upgrade revolves around a 2.9-liter twin-screw Gen4 supercharger paired with an advanced TripleCooled air-to-liquid intercooler. Complemented by Callaway’s proprietary "CalCal" engine software tuning, the modification significantly enhances the Corvette’s factory 6.2-liter LT2 V8 engine.
While the standard E-Ray already delivers over 650 horsepower thanks to its hybrid drivetrain combining a gasoline engine and a 160-horsepower electric motor, Callaway’s enhancements increase total output dramatically. The gasoline engine alone jumps to 687 horsepower and 643 pound-feet of torque, which when paired with the electric motor, culminates in a combined 847 horsepower—one of the highest outputs ever offered in a street-legal Corvette.
Notably, Callaway’s upgrade isn't limited to the E-Ray. The supercharger kit also fits the non-hybrid C8 Corvette Stingray, which shares the same gasoline V8 powerplant. When fitted to the Stingray, Callaway claims the supercharged Corvette accelerates from 0-60 mph in a blistering 2.67 seconds and covers the quarter-mile in just 10.64 seconds at 129 mph.

Despite the substantial power boost, Callaway emphasizes efficiency and reliability, stating the supercharger requires minimal engine power to operate—just one horsepower—ensuring negligible impact on fuel economy. The upgrade retains all original factory sensors and complies fully with federal and state emissions regulations, including California’s stringent CARB standards.
Customers purchasing the Callaway supercharger package will receive unique badging, a leather-bound authenticity certificate, and peace of mind through a three-year, 36,000-mile warranty running alongside GM's factory coverage. Additional customization options include a widebody kit, a signature double-D exhaust system, forged nine-spoke wheels, performance chassis upgrades, and exclusive graphic packages.
Callaway-authorized Chevrolet dealerships in North America are now accepting reservations for the upgrade with a $1,000 deposit required to secure a build slot.
