GM Surprises Show With CTS Coupe Concept

General Motors Corp. delivers the first surprise of the auto show with a Cadillac CTS concept coupe, a vehicle that exemplifies the luxury brand's future design direction and confirms a new diesel-engine application.

“It's a little too early to announce production, but if you look underneath, you can see that it's a real car,” says GM Vice Chairman and product boss Bob Lutz. “We call it a concept coupe, but it would be reasonable to assume that we plan to expand the Cadillac line to include a (car) like that.”

The long-rumored coupe caught the motoring press by surprise, as it was the one introduction GM did not brief journalists about ahead of the show.
