I got it from here. It's not clear if it's an artists conception or an official ford illustration.
Looks like an artist illustration, taking heavy cues from that Italdesign Mustang concept from a few years ago.
Personally, I have no problem with a turbo 4, and the only reason I hated the older V6 Camaro and Mustang was that those were not very good engines. Now they're considerably better. As long as its a good engine, I say the more options the better.
I hate supercharger whine, especially on a big V8 (if its very pronounced like in the video posted). Its like the War of the Worlds remake with the girl constantly screaming over low frequency sounds.
I'm also baffled at the person saying superchargers sound better than turbos, as you rarely can hear turbos over the exhaust noise (then again, maybe that's their point, they want to hear that whining?).
I have to say I love what I'm reading. The Corvette and now this, sounds great to me personally.
