Cadillac Provoq Hydrogen Fuel Cell Concept Revealed
Jan 8th, 2008 by Steve
GM showed off it’s new Hydrogen fuel cell based "crossover" concept car at CES in Las Vegas this week.
The Provoq is built on the same E-Flex system that the electronic Volt that debuted at the Detroit show.
What’s special about this (other than the cool styling)? To quote GM:
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…the electricity generated by the fuel cell is distributed to a 70 kW co-axial drive system for the front wheels and individual, 40 kW wheel hub motors on the rear wheels, giving the Cadillac Provoq its all-wheel-drive traction and great driving dynamics. Its 0-60 mph (approximately 100 km/h) speed of 8.5 seconds is a more than 30-percent improvement over the previous-generation fuel cell system and with instantaneous torque to the wheels, it feels even faster. Provoq has a top speed of 100 mph (160 km/h).
