LAS VEGAS —
Describing freedom from petroleum fuels and emissions as the "ultimate luxury," GM' unveiled its Cadillac Provoq Concept at CES 2008 in the hope of furthering their reputation as a forward-thinking carmaker.
Hot on the heels of their recent announcement that driverless cars will become a reality within ten years, the Provoq transplants the Volt Concept's futuristic powertrain
into a Cadillac package. But this time, it's a hydrogen fuel cell E-Flex system. This is the General's fifth gen fuel cell system and uses a lithium ion battery pack. The concept is said to travel 300 miles on a tank of hydrogen. That's 280 miles on hydrogen alone and another 20 miles on pure battery energy. A pair of 10,000-psi storage tanks sit beneath the cargo hold and contain 13.2 pounds of hydrogen. The fuel cell stack is located under the hood and the battery pack (presumably manufactured by A123Systems) can store 9kWh of energy with a peak of 60kW. This gesture reinforces Bob Lutz's assertion that the Volt, and its platform mates from the rest of GM's brands will be commercially available by late 2010.
The all-wheel drive Provoq is said to hit 60 mph in 8.5 seconds and a top out at 100 mph. That's a 30 percent improvement over the General's previous-gen fuel cell system. At speed, louvers in the grille close at highway speeds for enhanced aerodynamics. A by-wire brake system helps slow the Provoq. A solar panel on the roof helps power onboard accessories. The 21-inch wheels are covered in custom Michelin "Green-X" low rolling resistance tires. Much of the interior is produced from sustainable resources, like the headliner, which is a fully recyclable soy-based material.
Whether or not the Provoq evolves into a production vehicle remains to be seen. But in concert with the highly anticipated 2009 CTS-V, which will debut at the 2008 Detroit Auto Show, the Provoq Concept proves that the Cadillac brand may now becoming a relevant "Green" flagship for the largest domestic manufacturer. —Basem Wasef
