This is what Kicking Tires has to say about the new 2008 Cadillac CTS Sport Concept:

Looks like: A beefier Cadillac CTS
Defining characteristics: Hood scoops and a mesh grille
Ridiculous features: The idea that the new CTS’ grille needed more-radical styling
Chance of being mass-produced: The Sport itself might not become a model, but it could serve as a precursor to the next CTS-V

The new Cadillac CTS in this Sport concept was added with more performance but it was less appealing than the next seriously beefed-up CTS-V. “Since the V line came to the new generation of Caddies, they’ve brought bright grillwork. That’s definitely the trademark styling here, as well,” Kicking Tires revealed.

It may not have the Acura TL radiator but the new car was given more effective 20-inch polished wheels, a Corsa cat-back exhaust with modified tips that integrate into the rear bumper and stronger brakes. Some of the car changes are seen in the picture above.
