It might become a production car someday. It might not. Either way, the Cadillac Escala Concept offers up hints for the future of the company's lineup. Positioned as a more elite alternative to the CT6, it measures an impressive 210.5 inches long, and is powered by a 4.2-liter twin-turbo V-8 engine. Cosmetically, it has agressive lines, "3D"-like grille and wheel treatments, and OLED headlights buried deep in the front fascia, while inside it's split into two distinct sections, with driving-focused screens and features up front and a backseat designed for relaxation.
