More power and better fuel efficiency than previous generation Corvette

It wasn't so long ago that you were guaranteed to get poor fuel economy if you purchased a high-powered sports car. However, with manufacturers all around the world working hard to provide their vehicles with the best fuel efficiency possible, even sports cars and now getting downright miserly when it comes to fuel consumption.
 
A perfect example is the new EPA estimated 29 mpg fuel efficiency rating granted to the Chevrolet Corvette Stingray.

At 29 MPG, the Stingray is the most fuel-efficient “high horsepower” sports car on the market according to GM. The 455hp Stingray has an EPA estimate of 17 mpg in the city and 29 MPG on the highway. The new Corvette also has a driver selectable Eco-mode which boosts efficiency to 30 mpg on the highway. Eco-mode is available on Stingrays equipped with the seven-speed manual transmission.

“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 Eco-mode enables Active Fuel Management, which allows four of the eight cylinders in the high-powered V-8 engine be disabled for better fuel economy. Stingrays that feature the six-speed automatic transmission also get Active Fuel Management, but that fuel management is active in all drive modes unless the drivers using the manual-shift mode and steering wheel paddles.

 
EPA estimates for the automatic Corvette are not available.

Chevrolet points out that the highway fuel efficiency rating for the new Stingray is 11% better than the previous Corvette despite the new 6.2-liter V8 engine producing 6% more power compared to the previous Corvette.
 
The Stingray coupe will go on sale this fall with the convertible coming later in the year.

It's not and you have to wonder what GM was thinking by wasting dev and engineering time implementing this on a car that people buy for fun and for outright performance.

Having said that, anyone else think they failed on the rear end of the car? The front end looks Corvetteish - the rear end, though...doesn't.


They failed all over this car. It's hideous. It's like they saw the new SRT Viper and were entranced by how sexy it is, then they tried to copy it and make the vette have its own look similar to the Viper...in doing so made it fugly beyond belief. What do you expect from a company that's essentially funded by taxpayers and (indirectly) run government bureaucrats?
