Cadillac's Provoq hydrogen fuel cell concept showcases both technological innovation and the future of
CadillacSUV design. Utilizing GM's fifth-generation fuel cell stack, the Provoq is powered by one electric motor at the front wheels and two smaller units at each rear wheel. Other innovations include electronic brake-by-wire technology and front grille louvers that close at highway speeds to improve aerodynamics. While it'll be years before we see many of these technologies in showrooms, the Provoq's sleek design will likely influence Cadillac's next-generation mid-size SUV.
