Fuel-Cell-Powered Cadillac Provoq Unveiled at Electronics Show
January 16, 2008
GM's latest incarnation of its "E-Flex" propulsion system—the one initially designed for the Chevrolet Volt—is a fuel-cell-powered crossover vehicle carrying the Cadillac badge. The Cadillac Provoq concept vehicle was unveiled on January 8 at the Consumer Electronics Show in Las Vegas, Nevada, and is also on display at the Detroit Auto Show. The vehicle achieves a 300-mile range by packing two high-pressure hydrogen storage tanks beneath its rear cargo floor. It combines an 88-kilowatt fuel cell with a 60-kilowatt lithium-ion battery pack that can store up to 9 kilowatt-hours of electrical energy. It features a 70-kilowatt coaxial motor drive system for the front wheels and a 40-kilowatt motor in each of the rear wheel hubs, providing enough kick to boost the vehicle to 60 miles per hour in about 8.5 seconds. The vehicle has a top speed of 100 miles per hour.
Additional features built into the Cadillac Provoq include a solar panel integrated into its roof, brake-by-wire technology, and front grill louvers that close at highway speeds to enhance the vehicle's aerodynamics. See the GM press release, and a selection of photos of the Cadillac Provoq.
