Yep, more so with the new GM 7spd manual transmission they are working on. I know that gear box isn't only going to be used in the Corvette.
Throw on some of their electromagnetic shocks, carbon brakes, price it at $60k and you have a real RS4, M3, C63 AMG competitor!
GM has all the kit in house to build a car to play with the big boys, if the CTSV is any indication they will!
That would really be a good segment for them considering the Japanese are not in it, and the Koreans don't really have the technology yet; also the other two American manufactures are not in it either.
