During the 60 minutes show on Sunday, GM Vice Chairman Bob Lutz and CEO Rick Wagoner previewed a new Cadillac model believed to be the 2008 CTS. This model, among with BIuck and Pontiac new model are the new hoppe for GM.

Those cars are still in blue shrouds at the company’s super-secret design center in Warren, Mich., under the watchful eye of 74-year-old vice chairman Bob Lutz, a legendary Detroit design guru, who once ran Chrysler.

Unfortunately this is a car that I'd like to be able to show you, but for competitive reasons we can't show it all. I'll just show you some of the, some of the advanced work that we're doing on grills — that this is obviously a Cadillac, no concealing that, Lutz said.
