The last piece of performance information we’ve been waiting on for the new 2014 Corvette Stingray has been the EPA fuel economy numbers. GM is now confirming that the 2014 Corvette Stingray equipped with the 455 horsepower LT1 and a 7-speed manual transmission gets an EPA-estimated 17 miles per gallon in the city and 29 mpg highway.
That makes the Corvette Stingray the most efficient sports car on the market today. No other sports car offers more than 455 horsepower and greater than 29 mpg highway.
The 29 mpg highway rating represents an 11 percent increase over the fuel economy of the previous generation’s LS3-powered Corvette, while the 6.2L LT1 delivers 455 horsepower, a 6 percent increase over the previous generation Corvette as well.
We can already hear some lamenting that GM couldn’t get that 1 extra mpg so that the highway mpg number would break though the 30 mpg barrier. Well, with the Drivers Select Mode set in Eco, the Corvette Stingray does gets 30 mph Highway.
The 29 mpg highway rating reflects an average fuel economy in two of the Stingray’s Driver Select Modes: “Tour” and “Eco”. In Tour mode, the Corvette delivered 28 mpg highway and in the more fuel efficient Eco mode which activates the Active Fuel Management system, the Corvette Stingray hit the magical 30 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.”
So how does the Corvette Stingray’s fuel economy compare to others in the class?
Chevrolet may have found the sweet spot between performance and fuel efficiency with the 455 horsepower and 29 mpg Corvette Stingray. Sports cars with more than 455 horsepower typically offer significantly lower highway fuel economy estimates than the Corvette Stingray while those with higher highway mpg’s offer significantly less horsepower. Chevy offers up the ratings of several competitors to make its case.
|Audi R8 V10||510||19|
|Jaguar X-Type S||495||23|
|Porsche 911 Carrera S||400||27|
|BMW Z4 sDrive28||241||34|
Although the EPA estimates are based on the 455-hp base LT1 with the seven-speed transmission, Chevrolet says estimates for Corvette Stingrays equipped with the six-speed automatic will be coming soon.
While many think that Corvette owners are only obsessed with power, we hear all the time from owners about how well their Corvettes do mileage-wise with many reporting much higher rates based on the geography and driving conditions.
So you can bet that once owners start driving their C7s and taking in the major Corvette shows next summer, we’re going to hear the real story about just how fuel efficient the new 455 hp Corvette Stingray really is.
