GM designers and engineers were given free reign and unlimited resources to create the Cadillac CTS coupe. design. 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 is a new 2.9L turbo-diesel currently in development that generates 250 horses, and a six-speed manual gearbox sends a whopping 406 lb.-ft. of torque to an independently sprung rear axle. With slightly lower ride height than a production CTS, the coupe rides on split-spoke, aluminum alloy wheels, 20-inch front and 21-inch rear.
