But Volkswagen has designed its underpinnings to handle a striking array of fuels, including hydrogen.

The tanks sit under the cargo bay and rear seat, and the fuel-cell stack and electric drive motor sit in the engine compartment.

The motor comes from the 2015 Volkswagen e-Golf, and the lithium-ion battery pack (to smooth transient power demands) from the VW Jetta Hybrid.

Under VW Group's luxury Audi brand, hydrogen was used to power a plug-in hybrid concept that delivered 15 or 20 miles of battery-electric power before switching over to the fuel cell.

While this setup is even more expensive than a regular fuel-cell vehicle, Audi built its concept to demonstrate that hydrogen vehicles could deliver performance as well as zero-emission travel.

Its two electric motors, one per axle, delivered quattro all-wheel drive, while the 8.8-kilowatt-hour battery provided energy for sustained full-bore acceleration when needed--and recharged itself from the fuel cell output under normal circumstances.

Finally, Hyundai had its hydrogen-powered Tucson crossover utility vehicle on display at the Los Angeles show as well.

The Korean maker didn't provide any new information on that car, which began leasing in June--making it the first of a new generation of hydrogen fuel-cell vehicles to hit California roads.

It did, however, issue a brochure to the news media that reprinted its responses to Green Car Reports' 10 questions for makers of hydrogen fuel-cell cars.

That article, which continues to generate traffic and comments, highlighted some of the issues that Toyota, Hyundai, and Honda must address as they roll out their hydrogen powered vehicles.
