Corvette engineers rarely rest. They use a very capable system and look for room for improvement. The 2027 Corvette Grand Sport The revised Stealth Mode now allows electric travel at speeds of up to 80 km/h, an increase of five miles per hour over the E-Ray’s limit of 45 km/h. The difference may seem small, but it extends the hybrid’s quiet operation across a wide range of suburban and urban driving conditions. Corvette Chief Engineer Josh Holder admits his team never stops tinkering. “Engineers don’t like to stop working on something,” Holder said, and the improved Stealth Mode proves his point.
The C8 Grand Sport It inherits the more powerful front-axle electric motor from the ZR1X, producing 186 horsepower and 145 pound-feet of torque. The outgoing E-Ray produced 160 horsepower and 125 pound-feet of twist. More power means the hybrid system can push the car to higher electric speeds without taxing the hardware. Drivers who appreciate a quiet departure from their surroundings will appreciate this extra capability. Those who prefer to wake the neighbors can turn off Stealth Mode and let the 6.67 V8 LS6 sing through the optional center exit exhaust.
Chevrolet also added a Shuttle mode for low-speed maneuvers. This setting limits electric drive at 23 mph, useful for navigating parking structures or creeping through gated communities without a single piston firing. Holder notes that the Grand Sport typically arrives towards the end of a generation’s life cycle, and we can “expect a similar formula.” The formula here involves meaningful refinement, not just badge engineering. The 2027 Corvette Grand Sport Engineers gave it a longer leash and a more powerful motor. The results speak for themselves.
