Unfortunately I don't think it'll be the same. If they're talking about sharing a common platform I have my doubts it will have the performance potential it does now. You can only put a rear wheel drive sedan setup so far (Camaro Z28 is a good example). It might punch way above its weight, but a dedicated performance design from the start would be a better performer. Then again, maybe "common platforms" don't work the way I think they do.
