Audi debuts hydrogen-fueled electric A7 in Los Angeles (pictures)

Audi showed off its A7 h-tron, a new fuel cell development vehicle, at the 2014 Los Angeles auto show.

The A7 h-tron represents one of several efforts by Audi to develop a zero emission vehicle. The car uses a unique mix of lithium-ion battery and electricity-generating fuel cell.

A lithium-ion battery pack and four hydrogen tanks packaged in the car feeding a fuel cell stack power electric motors at the front and rear wheels.

The right rear fender holds a hydrogen filler for the car's 5 kilogram hydrogen tank capacity.

The left rear fender has a J1772 electric charging port, connected to the car's 8.8 kilowatt-hour lithium-ion battery pack.

Audi offered rides at the show to demonstrate the car's practicality.

The cabin retains much of what you would expect from an A7.

Audi places a power gauge on the left of the instrument cluster.

With electric motors at the front and rear wheels, the A7 h-tron doesn't need a traditional gear box. This shifter on the console selects the drive mode.

Audi implemented special screens to monitor the drivetrain performance, showing when power is regenerating, coming from the battery or generated by the fuel cell.

This consumption graph gives a rough idea of remaining hydrogen and battery power.
