I read a review on the SRT-8 challenger and indeed it weighs 4150 and will only be offered with an automatic the first year. It will be built in limited numbers at around 40 grand sticker and estimated mpg is 14/18 mpg. It will be followed by a tamer version. It's not as scarey as I first thought, as a limited production car we have all ready beaten it in hp with the shelby 500. We could give it a run for it's money with a GT at 4150 pounds and automatic. The tamer version will more than likely be the 5.7 and at that weight might be our launch or close stock. The mopar seems to be more hype than anything. Now the general maybe a different story, we'll have to see what the camero is bringing to the table, probobly us for lunch hee hee. The challenger only getting 14/18 mpg won't make many friends at the EPA. The stang still rules as I can be fast and still get 25 mpg on the highway.
