The Alpha chassis was designed to accommodate a V8 and you'll see it in the Alpha CTS-V. I do find it interesting that there are so many thinking the V8 is a thing of the past. The LT V8 will be with GM products for at least the production cycle of the just released trucks, C7 and coming SUVs. When the 6th Gen rolls out, there are numerous engine options available - turbo 4, V6 NA, V6 TT and of course a range of V8s. Listening to the rumor mills there is a 427 headed into the C7 Z06. With the 6th Gen Camaro production cycle two year or so behind the others the LT will be with us for 7 or 8 years ata minimum.

What I hear GM saying is that the V8 isn't going away, but the price of a V8 powered vehicle will be going up.

Its been discussed over on the Ford boards that they won't use the superchargers anymore and will move toward turbos.

The reason given is packaging.

The new Mustang is supposed to be a "global" car, and to do so it must pass European pedestrian collision regulations. The supercharger engine package is too tall to meet this standard.

I like the sound of those rumor mills.

...we have not seen the hand to be played by the C7 'Vette yet. So, we must stand pat until that time. In my heart of hearts in future speculation I say no.
