GM designers and engineers were given free reign and unlimited resources to create the Cadillac CTS coupe concept. Featuring a no B-pillar hardtop styling, the CTS production windshield was laid at a faster angle to create a sleeker profile. Inside the 2+2 cockpit layout, yellow ochre-colored seat inserts and leather stitching complement the black leather and microfiber trim. Under the hood was a new2.9L turbo-diesel that generated 250 horses and fitted with a six-speed manual gearbox.
