I didn't say that GM would have to use a turbo 6, i'm just saying... in a lot of ways there is more of a market for that now than there is for V8s cars. And if they made it with a high tech engine and image, they could possibly woo hundreds of thousands of those ricers out there. Just a possibility, which GM wouldn't have if it ties itself down with a Camaro, which will only be acceptable with a V8 and rwd, and might not sell no matter what.
