Just put FCHV in the search. I can't seem to get the link to go to where I was. Its the 2009 video.
"The Toyota Highlander Fuel Cell Hybrid Vehicle – Advanced (FCHV-adv) achieved an estimated range of 431 miles on a single full tank of compressed hydrogen gas, and an average fuel economy of 68.3 miles/kg (approximate mpg equivalent) during a day-long trip down the southern California coast."
