Corvette Stingray

The 2014 Corvette Stingray will deliver up to an EPA-estimated 17 miles per gallon in the city, and 29 mpg on the highway, making the new Stingray the most fuel efficient sports car on the market as no other car offers more than 455 horsepower and greater than 29 mpg highway. “The Corvette Stingray establishes the benchmark for modern performance cars by using technologies to deliver more performance and more miles per gallon,” said Tadge Juechter, executive chief engineer for the Corvette. “We expect more and more performance cars will follow Corvette’s example.” The EPA estimate of 17 city and 29 highway is for the Corvette Stingray equipped with an all-new, seven-speed manual transmission. The estimate reflects an average of fuel economy in both the default “Tour” mode, which delivers 28 mpg highway, and driver-selectable “Eco” mode, which delivers 30 mpg highway. For Stingrays equipped with the seven-speed manual transmission, Eco mode enables Active Fuel Management, which disables four of the cylinders for improved fuel economy during light engine loads. For Corvette Stingrays equipped with the six-speed automatic, Active Fuel Management is active in all drive modes until the driver engages the manual-shift mode using the steering-wheel paddles. Fuel economy estimates for Corvette Stingrays equipped with the six-speed automatic will be finalized soon. The highway rating represents an 11-percent increase in fuel economy over the previous Corvette, while the all-new 6.2L LT1 V-8 delivers 455 horsepower, a 6-percent increase over the previous Corvette. The LT1 delivers 460 horsepower with the available dual-mode exhaust. By comparison, the Porsche 911 Carrera S delivers 400 horsepower, and an EPA-estimated 27 mpg highway. Sports cars with more than 455 horsepower typically offer significantly lower highway fuel economy estimates than the Corvette Stingray. For example, the Jaguar F-Type S offers 495 hp and 23 mpg highway while the Audi R8 V10 offers 510 hp and 19 mpg highway. Sports cars that deliver more than 29 mpg highway based on EPA estimates typically deliver significantly less engine output. For example, the Porsche Cayman offers 30 mpg and 275 hp while the BMW Z4 sDrive28 delivers 34 mpg and 241 hp. The 2014 Corvette Stingray coupe goes on sale this fall, with a convertible following by the end of the year. Source: media.gm
