Cadillac luxury transportation

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.

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.”

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.

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.”

  • 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

Purposefully dynamic design

Highlights include:

  • Active front grille, with grille louvers that open when the fuel cell stack requires cooling
  • Full underbody aerodynamic cover
  • Left- and right-hand charging ports incorporated in stylish front fender vents
  • Flush door handles that feature push-to-release operation
  • Wind tunnel-shaped outside mirrors with integral turn signals
  • Center high-mounted rear stop lamp incorporated into full-width, wraparound spoiler
  • Signature vertical taillamps with subtle fin design

“From the strong, shield grille and vertical headlamps to the crisp body lines, the Provoq is instantly recognizable as a contemporary Cadillac,” said Hoon Kim, exterior lead designer. “Like the new CTS, it is bold and expressive, but there is enhanced shape between the edges – it’s a new proportion for crossovers, with a fast, almost coupe-like rear.

Kim points to the fender-mounted charge ports as prime example. They allow overnight, plug-in charging that extends the driving range. The ports have a satin-chrome appearance that incorporates an amber light to indicate the system is charging and a green light to indicate when charging is completed.

The vertical, neon-lit taillamps blend style with functionality, too, as their finned shape was designed to make the Provoq as aerodynamically efficient as possible.

A variety of recycled and recyclable materials were used, as well. Highlights include:

  • The headliner is wrapped in a fully recyclable soy-based material
  • The carpet is made of recycled polyester and jute
  • Leather used to cover the seats and instrumental panel is free of harmful chemicals
  • Xorel material used on the door panels and instrument panel; treated to perform as a carbon-fiber-type material
  • Chrome trim made with less-harmful materials
