Organizer Louis Palmer, a Swiss schoolteacher who made headlines with his 18-month pioneering world tour in a solar-powered "taxi" three years ago, said the three vehicles spent 80 days on the road.
"We wanted to show to the people of the world that we want this change, we all want these electric cars," he said. "We made it around the world in 80 days, we made it back here after 17 countries and 29,000 kilometers. We can’t believe it."
The UN-backed "Zero Race" stopped off at the World Climate Conference in Cancun, Mexico last December, after touring through Europe, Russia, China, Canada and the United States, before heading back through Morocco and Spain about a month behind schedule.
