Chevrolet Corvette trim comparison
2027 Chevrolet Corvette Grand Sport vs Z06
The Corvette Grand Sport starts at $93,100 while the Z06 is $139,450. That $46,350 gap buys 3 meaningful differences.
This trim jump changes the engine from 6.7L V8 to 5.5L V8. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the Grand Sport if the 6.7L V8 already feels sufficient for the way you drive. Step up to the Z06 only when the 5.5L V8 powertrain is the reason you are moving higher in the lineup.
If you are budgeting this move monthly, the jump from the Grand Sport to the Z06 is about $817/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $49,020 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
