Official Word:

The Chrysler ecoVoyager Concept celebrates the romance of automobile travel embodied in a four-door, four-passenger distinctively American design. Designed for customers seeking elegance, simplicity and serenity, the elegant one-box design takes advantage of space normally occupied by a conventional powertrain setup. The Chrysler ecoVoyager features an advanced lithium-ion battery pack, along with a small, advanced hydrogen fuel cell that serves as a range extender. The result is a vehicle with a total range of more than 300 miles that emits no emissions from the tailpipe except water vapor.
