General Motors has unveiled its new Cadillac Provoq Hydrogen concept vehicle at the Consumer Electronics Show in Las Vegas, NV.The Provoq contains two 10,000-psi Hydrogen tanks that feed a fuel-cell stack to produce up to 88kW of continuous power that charges a lithium-ion battery pack. This power is used to spin both a 70 kW co-axial electric drive system at the front wheels and two 40 kW in-wheel motors at the rear. Fully fueled and charged, the Provoq will run 300 miles and get to sixty miles per hour in a respectable 8.5 seconds and achieve a top speed of 100 mph.
The Provoq also comes with several nice options including dual battery charging ports in the left and right front fenders, a roof-mounted solar panel to boost the electric charge, and front grille louvers that close up at highway speeds to improve aerodynamics.
