Ever since the Camaro came out there were spottings of a Supercharged Version all around, then the Bankrupcy thing happened and they said all plans are scrapped and the highest version will always be the SS with 426HP....then rumors surfaced that the Z28 was back on....Even when asked at Carlisle the GM spokesmen hinted that it was coming....Probably just later on....
Good Marketing idea by GM....say the Z28 is dead so everyone goes out, buys an SS at higher then retail...then come out with the Z28 a year later so people sell the SS and get a Z28....
So not it seems to be back on....this coupled with the Cadi V Series seems like Muscle is still sticking around:
