I'd say the most major disappointment for me in seeing what the Camaro has over the CTS-V:
A LARGER FUEL TANK
I thought that I saw on this forum or somewhere else that GM is working on a "smart windshield" that would offer the ususal HUD functions and some other features. Maybe we'll see that in the next generation "V." It is a better concept than cutting a hole in the dash for the current, crude technology, and might not add additional weight.
Yeah, I saw something about that windshield a while ago, looks like a grea technology. Will it be ready in time for the next V, I'm not sure.
