The new 6.2 liter LT1 V8 engine in the 2014 Corvette Stingray is a thing of beauty. It makes over 450 horsepower, which makes it one of the most powerful naturally-aspirated V8s in the world, and now as it turns out it is also one of the most fuel efficient V8s as well.

The Stingray has received its official EPA ratings, and it’s certified at 17 miles per gallon in the city, and 29 mpg on the highway. These figures are the models equipped with the all-new, seven-speed manual transmission.

The LT1 benefits from direct injection, Active Fuel Management, continuously variable valve timing and an advanced combustion system. There is an driver-selectable Eco mode available that once activated engages the fuel management system, and makes possible to do 30 mpg on the highway. Amazing numbers for a fast and powerful muscle car.

Ratings for the Stingrays equipped with the six-speed automatic transmission are not finalized yet, but seeing as in those models the active fuel management system is active all the time unless you switch to the paddle shifters, it should be pretty good as well.

We would also like to know how the Stingray fitted with the Z51 Performance Pack does economy-wise. That one does 0 to 60 in 3.8 seconds, and frankly is the one to go for if you are buying a C7.
