Key Differences
-
The Corvette has 190 hp more power
Not a close call. The Corvette lists 490 hp and the 718 Cayman lists 300 hp. That’s a substantial gap. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The 718 Cayman has better fuel economy
Among all the differences on this page, 22 mpg against 19 mpg is one of the most meaningful, and it favors the 718 Cayman. The 718 Cayman uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The Corvette has 185 lb-ft more torque
The 718 Cayman gives up a lot on torque: 280 lb-ft, compared with 465 lb-ft on the Corvette. The Corvette’s extra torque makes it more relaxed when fully loaded or towing.
-
The 718 Cayman has better city fuel economy
Few buyers will miss this one. The 718 Cayman brings 20 mpg to the table; the Corvette brings 16 mpg. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
-
The Corvette has available all-wheel drive
Missing features are easy to overlook when you buy and hard to live without later. The 718 Cayman skips this one. The Corvette offers all-wheel drive; the 718 Cayman doesn’t, which matters if you face harsh winters.
