Chevrolet recently released some impressive Corvette Stingray numbers — 455 horsepower and a 3.8-second zero-to-60 sprint — but the bow-tie brand isn't finished. Chevy previously said it expected the 2014 Corvette to exceed 26 mpg on the highway, and the automaker today announced an EPA rating of 17/29 mpg city/highway. "No other car offers more than 455 horsepower and greater than 29 mpg highway," Chevy said in a statement.
Power comes from the next-generation 6.2-liter V-8 paired with a six-speed automatic or new seven-speed manual transmission. The 17/29 rating is for manual-equipped cars, and GM says it's an average of the default Tour mode (28 mpg highway) and the driver-selectable Eco mode (30 mpg highway). In Eco mode, the Active Fuel Management system is also engaged; it automatically disables four of the cylinders during light engine loads. Fuel-economy estimates for six-speed automatic models will be finalized soon, GM said.
It's unclear if the 17/29 rating is for the base Corvette or models equipped with the optional Z51 Performance Package ($2,800). The Z51 package uses a different transmission gearing, which could impact fuel economy. GM hasn't yet responded to our questions regarding the package.
The highway figure is 11% better than the fuel economy returned by the previous-gen Corvette and competitive against other sports cars: The Porsche 911 Carrera S delivers 400 horsepower and 27 mpg on the highway, and Jaguar's F-Type S offers 495 hp and returns 23 mpg on the highway. The BMW Z4 sDrive28, however, delivers 34 mpg but offers just 241 hp from its four-cylinder engine.
The 2014 Corvette Stingray coupe goes on sale this fall with a starting price of $51,995; the convertible will follow at the end of the year and start at $56,995; all prices include a $995 destination fee.
