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.
The Cadillac Provoq uses the same eFlex architecture that was rolled out in early 2007 with the Chevy Volt. Actually, GM has been talking for many years about a plug-and-play vehicle architecture that can work with any power system or fuel source. GM uses this iteration as a platform for its fifth-generation fuel cell stacks, which the company says are half the size of its predecessor, but more powerful. The vehicle stores its hydrogen in two 10,000-psi composite fuel tanks mounted under the cargo floor—and its electricity in a lithium ion battery pack mounted under the rear seat. The two hydrogen tanks provide 280 miles of mobility, with the batteries providing 20 more miles of driving.
One charging port isn’t enough for its plug-in capabilities. The Provoq has His and Hers, left- and right-hand inserts incorporated into the front fender vents. A 70-kW motor is posted up front and two 40-kW motors are tucked in the rear wheel hubs.
In addition to the juice running in and out of the lithium batteries, capable of storing 9kWh of energy, solar panel integrated in the roof provide help to power onboard accessories and lights.
This SUV—which seats five and incorporates the “comfort, convenience and infotainment features Cadillac customers seek,” according to the press release—is aerodynamic. The drag on the massive Provoq is mitigated by front grille louvers that close at highway speeds, and open back up again at low speeds to cool the fuel stack. Other tricks to reduce air resistance are a sloping roofline, low-drag roof rack, an underbody cover, and even cute little tail fins. Twenty-one-inch wheels are covered in custom Michelin “Green-X” low rolling resistance tires.
The Provoq is obviously being used as a chance for GM to show off all its cute ideas—and as such, shouldn’t be taken too seriously by green-leaning car shoppers. Unless you want to think of the use of recyclable soy-based material in the Provoq’s interior as anything but a coy act of provocation—considering GM’s record on fuel efficiency and the environment.
With sleek, signature Cadillac bodywork, the Provoq concept redefines luxury crossovers, offering uncompromising passenger and cargo space to match its performance and cruising range. Additional vehicle features include:
- Solar panel integrated in the roof to help power onboard accessories, such as the interior lights, audio system and more
- Brake-by-wire technology
- Front grille louvers that close at highway speed to enhance aerodynamics, and open at low speed to provide maximum cooling to the fuel cell stack
