Chevrolet Corvette Stingray Concept - Is a hybrid powertrain in the Corvette's future?

Is GM really considering a hybrid Corvette? Tom Stephens, GM's vice chairman of global product development, says it's a possibility. However, Stephens' comments are based on the new CAFE standards -- 35.5 mpg by 2016 -- and would only happen if the Corvette's livelihood depends on fitting a hybrid drivetrain.

With Porsche, Audi, Mercedes and others showing electrics and other alternatively powered sports cars, and some companies doing nothing but hybrids or electrics (see: Fisker and Tesla), it isn't hard to imagine an electrically boosted fiberglass flyer. The question is whether or not Corvette buyers would even consider a hybrid.

For now GM thinks they have a good enough plan to keep the Corvette electron-free. Until a hybrid is the only option, expect future 'Vettes to be made lighter, and equipped with low rolling resistance tires, direct injection, variable valve timing, and cylinder deactivation to make them more fuel frugal. Even electric power steering can boost mileage by half a gallon. So although a hybrid Corvette hasn't been ruled out, Stephens does say that we shouldn't expect a six-cylinder in the 'Vette's engine bay anytime soon.

lower weight and physical size is the key to keeping the corvette viable. it may have to morph into something smaller, and i think they should develop a small v8, pushrod, like 4.0 litres as a base motor. get the car in at 3000 pounds, and give it a 400hp v8 base engine. thing should get 20/30 epa.

The possibilities are endless for improving fuel economy and performance. The latest 385-hp 911 Carrera S gets the fuel economy of a V6 family sedan.

The Green movment and CAFE has all sports car makers running scared. Well not all Lotus is making money from it and already has their cars set.

How would low rolling resistance tires work on a sports car? Wouldn't the tires just spin and the car go nowhere when you floor it from a stop?

LRR => stiffer sidewalls => more grip?

Why is GM so worried about the CAFE rating of some 30K sales a year? I'd rather see them be more aggressive in publicizing fuel economy improvement efforts in trucks/vans/SUVs (which weigh a lot more in their Corporate Average Fuel Economy and which may be the key for some RWD products to come back into the pipeline) than talking about some hypothetical Corvette hybrid.
