The Cadillac CTS Coupe Concept has a classic 2+2 interior layout, highlighted by black leather and microfiber trim that is complemented by yellow ochre-colored seat inserts and leather stitching. It shares the hand cut-and-sewn instrument panel and center console with the CTS, but features unique front and rear seats, a continuous console running between the front and rear seats, and custom door panels. It is designed to accommodate a range of engines for the global luxury market, including Cadillac’s popular 3.6L Direct Injection V-6, as well as a new 2.9L turbo-diesel currently in development.
A six-speed manual transmission backs the engine, sending torque to an independently sprung rear axle. The CTS Coupe’s sport-tuned suspension gives it a slightly lower ride height than a production CTS – a look enhanced by the car’s rakish shape and large, 20-inch front and 21-inch rear wheels.
Among the CTS Coupe Concept’s signature design cues are a number of elements that suggest the look of a carefully cut diamond – particularly at the rear. These elements are seen in everything from the chrome header above the rear license plate holder to the indents that comprise the basic form of the rear fascia.
