According to Cadillac, the Provoq is "a petroleum-free, hydrogen-powered vision of future luxury transportation." In fact, the official press release proclaims that "The concept can drive 300 miles (483 km) on a single fill of hydrogen – with 280 miles (450 km) from hydrogen and 20 miles (32 km) on pure, battery electric energy. A pair of 10,000 psi (700 bar) composite storage tanks beneath the rear cargo floor hold 13.2 pounds (6 kg) of hydrogen to feed the fuel cell stack, located under the hood. There, hydrogen mixes with oxygen to generate electricity – up to 88 kW continuous power. A lithium-ion battery pack can store up to a total of 9kWh of electrical energy and also provides a peak of 60 kW of power for additional performance." All this despite the fact that the Concept doesn't have any hydrogen-related parts whatsoever. So I rang-up Pete Barkey of GM Powertrain Communications and asked if GM has any intentions of building a Provoq Concept with a hydrogen engine. "I cannot tell you either way right now." David Caldwell of Cadillac Communications also pointed out that the press release uses a small "c" (concept) rather than a capital "C" (as in Provoq Concept). Both gentlemen also admitted that the numbers cited were entirely theoretical. Fair enough?
