Just over a month ago we brought you the first reports that the C7 Chevrolet Corvette is due to arrive in 2012, and now Ed Welburn, GM's product design head, has revealed that the next Vette will get a split rear window along with some other vintage styling cues.

The split rear window, though often considered an iconic Corvette element, was actually only fitted to the 1963 Corvette Sting Ray. It was also featured on the Stingray Concept car shown off for the Transformers movie debut, though GM and Welburn have both reiterated that the Stingray Concept is not the C7 Corvette.

While the stingray us undeniably Corvette, the next-gen Vette will be a bit more retron in its styling, not unlike the current 2010 Chevrolet Camaro, according to the report.

Our own previous reports also confirm that the mid-engine rumors for the C7 Corvette are just that--the next car will retain the traditional front engine/rear drive layout. It will continue to push forward with the use of high-tech materials including carbon fiber, aluminum and magnesium to help further reduce weight.

As we noted earlier today, the Corvette will also have to become somewhat more emissions-conscious thanks to new standards being implemented by the federal government. GM won't let that sap the car's legendary performance, however, vowing to do whatever it takes, including going hybrid, to keep the Vette alive and kicking.

One potential direction to help maintain performance and meet emissions targets is a reduced displacement forced-induction V-8 engine not unlike the LSA fitted to the current Cadillac CTS-V. Rated at 556 horsepower, that engine would be no slouch for even the Z06 application in the Corvette range, especially with a lighter curb weight than the C6 Corvettes.

It's not very likely the Corvette will go hybrid, says Tom Stephens, GM's vice chairman of global product development, but the company will do whatever it takes to keep the Corvette around once the recently announced fuel regulations raise the national standard to a company-wide 35.5 mpg average in 2016.

Stephens also says it's not likely that the Corvette will have to adopt a smaller six-cylinder engine either. Instead, a high-tech V-8 engine should be able to meet the fuel efficiency floor with the assistance of low rolling resistance tires, a lighter curb weight and electric power steering.

The engine itself would get direct injection, variable valve timing and cylinder deactivation to boost fuel economy. The current Corvette would need to nearly double its combined efficiency rating to meet the 35.5 mpg standard. Since the 35.5 mpg figure is a company average, however, GM could shoot for a more realistic target, say 30 mpg, and let its more efficient, higher-volume models pick up the slack.
