That smell your hands get from pumping your own gas. It lingers as a tell-tale sign that you’ve been fueling up. Toyota’s new hydrogen fuel cell technology is even stinkier… when it starts out.

The automaker has tapped award-winning documentary filmmaker Morgan Spurlock to show how calling hydrogen fuel cell vehicles “bullsh*t” isn’t far from the truth. Spurlock has directed a 3-minute video featuring the process used to create fuel for the Mirari covering everything from the back end of a cow to powering your way to work.

“This project gave us the opportunity to dive into a world that most people don’t understand but has the potential to change our world,” said Spurlock.  “Witnessing manure, something most of us view as being pretty disposable, being transformed into hydrogen fuel to power a car was pretty remarkable.  I think this short film is pretty compelling evidence of what could be possible in the years ahead.”

Beyond high quality dung, hydrogen can be manufactured from other renewable energy sources like solar, wind and biogas from landfills. These production methods can result in a domestic and locally sourced fuel that powers the Mirai while emitting only water vapor from the tailpipe.

The four-door, mid-sized Toyota Mirai delivers performance similar to traditional internal combustion engines – re-fueling in about five minutes and a range of up to 300 miles on a full tank. The Mirai will go on sale in October 2015 at eight California dealerships- San Francisco Toyota, Roseville Toyota, Stevens Creek Toyota, Toyota of Sunnyvale, Longo Toyota, Toyota Santa Monica, Toyota of Orange and Tustin Toyota.
