General Motors says in a press release that the 2014 Corvette gets 28 mpg on the highway in its normal Tour drive mode, while 30 mpg can be achieved on the highway by switching to the Corvette’s Eco drive mode. Selecting Eco mode engages the Corvette’s Active Fuel Management system, “which disables four of the cylinders for improved fuel economy during light engine loads.” Fuel economy estimates for models with the six-speed automatic transmission have not been released yet, but GM says that Corvettes with automatic transmissions use Active Fuel Management at all times, unless the driver uses the steering-wheel mounted paddle shifters to put the Corvette in manual mode.
GM says that the Stingray’s fuel economy rating makes it “the most fuel efficient sports car on the market as no other car offers more than 455 horsepower and greater than 29 mpg highway.” In comparison, less powerful cars like the Ford Mustang GT and BMW M3 earn 18/25 and 14/20 mpg, respectively, while the more powerful Nissan GT-R gets 16/23 mpg. The 400-horsepower Porsche 911 Carrera S gets 19/27 mpg city/highway. While the 911 Carrera S earns two mpg less on the highway, it does earn a slightly higher combined fuel economy estimate at 22 mpg.
The 2014 Corvette Stingray will go on sale this fall, while convertible models will hit dealer lots by the end of 2013. After a $995 destination charge, the Corvette Stingray will start at $51,995 and $56,995 for coupe and convertible models, respectively.
