The new Stingray isn't just powerful, it appears to be efficient.

The last remaining piece of the puzzle that is the 2014 Corvette Stingray appears to be now be in place, fuel economy. According to the EPA's website the 2014 Corvette Stingray will wear fuel economy ratings of 17 mpg city and an impressive 29 mpg highway when equipped with the car's Tremec seven-speed manual transmission.

At 17/29 mpg, the Stingray is seeing a sizable increase from today's Corvette, which is rated at 16/26 mpg when equipped with a six-speed manual transmission. The EPA has not yet published ratings for the Stingray with an automatic transmission.

The Corvette Stingray is powered by an all-new Generation V Small Block V-8. The 6.2-liter LT1 engine generates an estimated 455 horsepower and 450 foot-pounds of torque.

Chevrolet has not confirmed the ratings found on the EPA website.

Update: It's official...

Press Release said:
DETROIT – 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.

Very impressive! 1 more mpg for the magical mind barrier being broken down by nay sayers.

5 years 100,000 mile warranty. 450/450 hp/tq. Performance levels of $250,000 super cars. And 29mpg. All for less than $55K. No other car can touch this beautiful work of engineering might!

That's incredible...although kind of disappointing they couldn't eek out 1 more mpg though to hit 30. :dro:

Amazing, especially when that is better than my 3.6L 2008 Malibu is rated at and the Vette has nearly twice the HP!

I get 30 in my C6 - not hard to do.

Great!!

This is really showcasing American engineering. :)

You'll never see mpg numbers (or reliability) like this for a Ferrari.

Re: Breaking: 2014 Corvette Stingray Rated 29 MPG Highway

One has to wonder what the rumored "base" model will get with a smaller LT-style engine...Assuming that's what it's going to have under the hood, if it's even built at all.

And as mentioned above, C5 and C6 cars have no problem exceeding their respective EPA ratings in the real world, so it would be reasonably safe to assume that the LT1 will do the same.

And I'll join the "my car gets" club by stating that the LQ4 car in my signature regularly returns 28+ MPG on the highway with a light foot, but with a cam that doesn't like to idle at much under 900 RPMs and with more RWHP than the current LS3.

Hope you can turn the AFM off, what with the Silvy's burning oil while in AFM.

I agree with 63grand really. We seem to be the only two who are not impressed. Sure, 3 mpg highway is nice. But I always look at the number the automakers don't want you to, the city figure. So, compared to the old car, after all this time the Corvette gains 14 horses and 1 mpg? Good thing the interior gains so much in tech and material quality.

Some what disappointing with AFM on this engine.

So once again, it's proven that some folks will never be happy, even if the car makes 450/450, gets to 60 MPH in under 4 seconds, gets 29 MPG and starts under $55,000.

Go find another car that does all of these things and then you can claim that the Stingray is disappointing.

Meanwhile, perhaps you can reread your posts to see how ridiculous your comments are. This is not meant as a personal offense to either of you, but merely a suggestion to check yourselves, because what GM is doing with the C7 has never been accomplished before.

Amazing, it gets better mpg than some 4 bangers and most mid sized V6's
That's because on the highway it is a 4-banger. It's a 3.1 liter four when the car's in DoD mode, and they've carefully sized the engine so that in freeway cruising it can stay in 4 cylinder mode enough that it gets great fuel economy. (Though I've no doubt that the size of the engine, and the amount of 4-cylinder work it can do was set in part by the demands of EPA testing. In short, the engineers figured out how to ace the test.)

Think of the DoD trick as being like a turbo, but backwards. With a turbo, you add machinery to permit high output. With DoD, you add more engine, and then switch it off until needed. Think of it as four of the Corvette's cylinders are the turbo if you like.

So simple it's really quite ingenious. I'd rather have a big displacement instant torque engine than a little screamer with a turbo on it. It's like getting your cake and eating it too.
