It appears as if GM’s first hydrogen fuel cell car, the Cadillac Provoq, may be available for purchase sooner than we thought. 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.

From what we’re hearing, some time between March and June of 2009 is the time frame were looking at. 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.

Key features

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

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
  • Side glass mounted flush with pillars
  • Wheels with clear-covered space between the spokes, creating a sleeker profile while maintaining Cadillac’s signature bold wheel design
  • Low-drag roof rack

The Cadillac Provoq seats five and incorporates the comfort, convenience and infotainment features Cadillac customers seek. Most importantly, the fuel cell powertrain does not intrude on passenger or cargo room. The hydrogen fuel tanks are mounted beneath the cargo floor, with the storage batteries located at the center of the chassis. The fuel cell stack is located under the hood, giving the Provoq the interior layout of a conventional crossover – including a full cargo area and a 60/40-split folding rear seat.
