Kick Gas, a documentary about a gang of electric vehicle enthusiasts on a mission to set a new Guinness World record, has been released on this day, Earth Day, 2014. The vehicles included a Nissan Leaf, 2012 Zero S, a Xenon electric scooter, and an A2B Alva electric bicycle. The goal, then, was to cover 4000 miles in 44 days, starting from Charleston, South Carolina, to Google Headquarters in Mountain View, California.

Ben Rich, of Green Car Reports, rode the Zero on the trip, and tells just a few of his favorite memories from the journey in his column, but as you can imagine the effort was a giant undertaking. From managing the speeds of the vastly different vehicles, to staying focused and on track, the hurdles were many. Oh, and let’s not forget about the biggest hurdle of all: charging the batteries. Rich mentions that both coasts are fairly well equipped with a charging infrastructure, but when traveling west past the Mississippi River, charging became a problem. Thankfully, hotels, and RV campgrounds are rather prevalent throughout the country.

Check out the video trailer below to catch just a small glimpse of the record-setting effort. To download the whole movie, visit the Kick Gas website.
