I think they need to offer a V6 with it; otherwise, they will be cutting themselves very short in sales. Obviously the person who wrote the question about the success about the Camaro with fuel prices doesn't know GMs history of fuel mileage with V8s. The manual versions of the Camaro 5.7L were getting around 28 mpg, that is a higher fuel mileage rating than what my V6 is rated at. If they offer DOD & VVT on the Camaro mix with the tall geared T-56 Tremec they very well could get 30 mpg. Also if people are willing to buy SUVs from GM that are rated at 22 mpg, they will get a more fuel efficient Camaro.

I think there will be models of the Challenger that are made for people who care about fuel economy and power and others just for power. The 5.7L models will probably be made for those who want a compromise. If the 5.7L is given a T-56 6-speed I wouldn't be surprised if it got around 27-28 mpg.
