2014 Corvette is the most fuel-efficient premium sports car

The 455-horsepower V8 engine can deliver 30 mpg highway in Eco mode.

Because the 2014 Corvette Stingray can achieve an EPA-estimated 17 mpg city/29 mpg highway, Chevrolet said this will make it the most fuel-efficient sports car on the market when it goes on sale this fall.

It’s the only sports car that offers 455 horsepower and delivers 30 mpg highway in Eco mode.

The 17/29 estimate is for the 2014 Corvette Stingray equipped with a new 7-speed manual transmission, while the driver-selectable Eco mode helps it get up to 30 mpg highway. An Active Fuel Management system that disables half the cylinders of the Corvette's 6.2-liter V8 engine for enhanced fuel economy is activated only in Eco mode.

By comparison, the 3.8-liter 400-horsepower 6-cylinder engine in the 2014 Porsche 911 Carrera S delivers an EPA-estimated 27 mpg highway, although it does get 19 mpg city and 22 combined. But other manual-transmission 400-plus-horsepower sports cars – particularly those from Chevy’s domestic rivals – don’t come close.

The 2013 Dodge Challenger SRT8 equipped with a 392-cubic-inch 470-horsepower Hemi V8 gets 14 mpg city/23 mpg highway and 17 combined, while the 2014 Ford Mustang Shelby GT500 with a 5.8-liter V8 engine that produces a massive 662 horsepower has an EPA rating of 15/24/18. Certainly, other sports cars, such as the Subaru BRZ, achieve higher numbers, but when it comes to spending $50,000 and up, nothing else matches the Corvette.

The 2014 Corvette Stingray’s highway rating is an 11 percent increase over the previous model year, even though the new LT1 V8 delivers a 6 percent increase in horsepower over the previous base Corvette engine. When equipped with a 6-speed automatic transmission, the Corvette Stingray’s Active Fuel Management is active in all drive modes, except when the driver engages the manual shift via the steering-wheel paddles. (Fuel-economy estimates for Corvette Stingrays equipped with the 6-speed automatic haven’t yet been finalized.)

“The Corvette Stingray establishes the benchmark for modern performance cars by using technologies to deliver more performance and more miles per gallon,” Tadge Juechter, executive chief engineer for the Corvette, said in a statement. “We expect more and more performance cars will follow Corvette’s example.”

Glad to see an American car back on top. I think the Corvette is the only car with a non-hybrid, gasoline V8 that could actually achieve 30 MPG. Most other sports cars that can even come close to achieving such high mileage are typically turbo-charged.

Manufacturers have been sitting on their hands for far too long in achieving real gains in efficiency. There is no reason that consumers shouldn't have horsepower along with good mileage given the 7-9 speed transmissions and active fuel management systems. Now they need to start shedding weight and lots of it.

Corvette has always been the best bang for the buck and still is :)

"..........delivers 30 mpg highway in Eco mode"
Is that where you hoist the mainsail?  Or what?
Anybody who can keep their foot out of that gas pedal shouldn't own a Corvette.
Drive it like you stole it.  And like your dad owns the gas station.

Rented a 2010 and 2012 Impala, both with the 3.7L V-6 that was rated 29MPG highway. Made a 2600 mile round trip of 90% highway driving at 70MPH plus. Both cars returned an honest 33MPG. That's a calculated number and not computer number.


Maybe this Corvette will get even better highway MPG than rated.

Congrats to the Corvette are in order and its engineers.  That's a lofty MPG figure to achieve with that amount of power. Comparing its fuel economy to a Porsche 911 is a little odd to me. They are two completely different cars that offer completely different driving dynamics, characteristics and owner experiences. I have both in my family and can tell you they are two completely different cars.  Anyway, KUDOS to GM on the Vette's fuel economy,

And a tiny Mazda Miata with 167 hp gets 28 mpg highway ! Says something about American technology !

this is good news for team chevy. Im not sure how EPA runs their numbers or how it works. I know my 2002 c5 corvette gets about 34.3 on the highway if im easy on it [according to the computer before I put my headers on] now it gets about 27.6. highway untuned. 26.7 average without and 22.8 with headers still untuned. its really depending how you drive the car to get your numbers.. for the c7 at least if you want to play with the car a little you can adjust the settings in the car and turn off eco mode if you want.

Considering what a Corvette costs, I don't think the potential owners are dithering about gas mileage.  Congratulations to the Corvette engineering crew for making the LS that economical to drive.

However, the real fun in life is driving a car that costs thousands less, but can outrun a Corvette, and the Corvette engineers are making it harder every year.

It is somewhat dubious to jack up the gearing until a car is ready to stall and to call that more efficient.
The active management should be standard on all cars. Still there needs to be more technology, much lighter vehicles etc etc.
