Small and mid-sized luxury sedans are typically also offered in coupe forms and it has long been rumored that Cadillac would produce a coupe variant of its successful CTS. The CT coupe concept is the first such tangible evidence. With sleek and edgy styling, the coupe concept clearly amplifies the styling themes of Cadillac's modern products. The coupe shares only the front fenders, grille, and headlamps with the sedan. The inside of the coupe is finished with four Recaro seats. Only the instrument panel and center console are shared with the sedan. The coupe is designed share the same 3.6L V6 engines as the sedan, but the concept features an all-new 2.9L turbo-diesel.
