Click on the Cadillac Provoq concept for a high-res image gallery

Following the introductions of the Chevrolet Volt and Opel Flextreme during 2007 auto show season, Cadillac is bringing forth a third design based on the E-Flex architecture. The Cadillac Provoq concept is intended to help give the brand an image of premium sustainability by updating the fuel cell E-Flex powertrain that was shown in a Chevy Volt at the Shanghai Motor Show last year. The Provoq is a luxury crossover design that's considerably larger than the Volt.

With updated Cadillac styling cues on a 180-inch long CUV body, it's stretched 10 inches longer than a Volt to allow comfortable seating for five passengers. The Provoq is built around GM's fifth-generation fuel cell stack combined with a 9kWh lithium ion battery pack. The electrical energy is used to power a 70kW AC motor driving the front wheels and a pair of 40kW hub motors at each rear corner. Like the other E-Flex vehicles, the Provoq has plug-in capability and the battery has enough capacity for about twenty miles of driving range. Combined with the 6kg of compressed hydrogen gas stored in its two tanks, the Provoq has a total range of about 300 miles. Clay Dean's Cadillac design team incorporated some of the aerodynamic lessons learned by the Volt crew, including thermostatically controlled slats in the grille to minimize drag when cooling air flow isn't needed.
