It’s pretty obvious where the automotive industry is heading. GM is trying to make some bold statements about where it will be in the next few years. Yesterday, at CES, Rick Wagoner unveiled their latest concept, the Cadillac Provoq. This is the first time an automotive company has keynoted at CES, but I’m sure it’s not the last. That’s because future cars will be integrating more and more electrical components. The push is away from petroleum run vehicles and toward alternative fuels.
Here’s are the relevant snippets of GM’s press release:
“Cadillac is a natural fit for GM’s next step in developing the E-Flex platform,” says Jim Taylor, Cadillac general manager. “Cadillac, at its very essence, is about premium luxury, design and technology, so it’s fitting that Cadillac would be propelled by the most elegant solution. This signals Cadillac’s intent to lead the industry with alternative-fuel technology.”
Fuel-cell variant of the E-Flex system
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).”
Too little too late?
