No need for fuel, no emissions

Today at the CES (Consumer Electronics Show) in Las Vegas, Cadillac will be showing their latest concept vehicle called the Cadillac Provoq Concept. Today GM will begin showcasing its future performance technology and design which will continue at next week's 2008 NAIAS in Detroit.

The Cadillac Provoq Concept has the new SUV Coupe exterior, just like the BMW X6, Land Rover LRX Concept and probably the Hummer HX Concept, and can comfortably seat 5 passengers. The underpinnings is what sets the Provoq apart from the SUV Coupe crowd at Detroit though.

The Provoq is the third vehicle featuring GM's new E-Flex Powertrain (following the Chevy Volt and Opel Flextreme) and can therefore run on electric power (approximately 20 miles) and CNG natural gas (another 280 miles). The Provoq requires no petroleum based fuels and is therefor about as 'green' as cars come these days.

Whether Cadillac has more in store for us in regards to the Provoq Concept at next week's NAIAS show is uncertain, but they do have the world premiere of the high performance Cadillac CTS-V prepared.

Further details below.

Cadillac To Showcase Future Design And Performance Technology

Cadillac extends its ongoing design and technology momentum with tomorrow's debut of the Provoq Concept, a vision for a petroleum-free future of luxury transportation. GM CEO Rick Wagoner will present the Cadillac Provoq concept vehicle January 8 at the influential Consumer Electronics Show (CES) in Las Vegas, beginning a showcase of Cadillac's future performance technology and design that will continue at next week's North American International Auto Show (NAIAS) in Detroit.

The Provoq Concept continues Cadillac's remarkable heritage of landmark concept vehicles, this time in a vehicle free from petroleum fuel and emissions, the ultimate luxury. Provoq will make its world premiere at one of the world's leading technology showcases at CES, appearing again at one of the foremost automotive stages in Detroit on Jan. 14.

Cadillac accelerates into Detroit with another dramatic demonstration of its design and performance technology, the world premiere of the 2009 CTS-V. Cadillac's high performance V-Series represents the ultimate expression of the brand's performance and luxury, and the much-anticipated new CTS-V will include many significant technical and design enhancements aimed at placing it within the elite group of the world's most capable cars.

The 2009 CTS-V extends the momentum created by Cadillac's 2008 CTS Sport Sedan, which is earning wide acclaim from critics and consumers alike. Since September, CTS sales are up 59.5% in the U.S. CTS was recently named 2008 Motor Trend Car of the Year, headlining a long list of accolades that also includes positions on Car and Driver magazine's 10Best list and as a finalist for 2008 North American Car of the Year.

Also appearing in Detroit next week will be the Escalade Hybrid, featuring a fuel-saving Two Mode Hybrid system combining a gas engine with electric battery power. The Escalade Hybrid, beginning production in mid-2008, extends the desirability of the leading large luxury SUV.

Cadillac Provoq Fuel Cell Concept delivers clean, petroleum free performance and signature design

Cadillac unveils a new vision for the future of luxury transportation with the innovative Provoq fuel cell concept – a hydrogen fuel cell crossover vehicle that continues GM’s commitment to displace petroleum through advanced technology.

The Cadillac Provoq fuel cell concept is the latest example of GM’s groundbreaking E-Flex propulsion system, combining the new fifth-generation fuel cell system and a lithium-ion battery to produce an electrically driven vehicle that uses no petroleum and has no emission other than water. The concept’s fifth-generation fuel cell technology is half the size of its predecessor, yet it has been developed to produce more power and performance.

“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).

“This is a vision of what comes next – a fuel cell electric vehicle that delivers the driving characteristics Cadillac customers want and allowing them to do it without using a single drop of petroleum, while emitting only water vapor,” said Larry Burns, GM vice president for research and development. “This is proof that alternate fuels and advanced technologies create even greater opportunities to satisfy the luxury buyer.”
