Chevrolet has just announced that the 2014 Corvette Stingray will deliver an EPA-estimated 17 miles per gallon in the city and 29 mpg on the highway making it the most fuel-efficient sports car on the market. There is not a single other car that offers upwards of 455 horsepower paired with a fuel efficiency of 29 mpg highway or better. "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-estimates of 17 city and 29 highway are based on the Corvette Stingray paired with the all-new seven-speed manual transmission and reflects the average fuel economy in both the default "Tour" mode (28 mpg highway) and the optional "Eco" mode (30 mpg highway). "Eco" mode enables Active Fuel Management, which is responsible for disabling four of the cylinders during light engine loads, leading to improved fuel economy. Corvette Stingrays that are paired with the six-speed automatic transmission also feature Active Fuel Management which differs in that it is active in all drive modes until the driver engages the manual-shift mode using paddles located near the steering wheel. Fuel economy estimates for Corvette Stingrays equipped with the six-speed automatic have yet to be finalized. The all-new 2014 Corvette Stingray is significantly more fuel-efficient and more powerful than any of its predecessors. The highway rating represents an awesome 11% increase over the 2013 Corvette and the all-new 6.2L LT1 V8 power plant produces 455 horsepower which is a 6% increase. It should be noted that the LT1 delivers five added horses with the optional dual-mode exhaust. Sports cars producing as much horsepower as the new Stingray typically offer significantly lower highway fuel economy estimates. One simply has to look at the competition to put these numbers in perspective. For instance, the Porsche 911 Carrera S delivers 400 horsepower, and achieves an EPA-estimated 27 mpg highway. The Jaguar X-Type S offers 495 horsepower and 23 mpg highway, while the Audi R8 V10 offers 510 horses and only 19 mpg highway. Perspective buyers can look for the 2014 Corvette Stingray coupe to go on sale this fall, with a convertible following by the end of the year. By Stephanie Davies Enjoyed this Post?
