Mercedes-Benz has just wrapped up its world tour with the company's F-Cell fuel-cell vehicle. The trio of hydrogen-powered futuristic hatches wandered the entire circumference of the globe and racked up around 18,641 miles each in the process. The whole shebang wrapped up in front of the Mercedes-Benz headquarters in Stuttgart – the exact location where the vehicles began their journey back in January.

The German automaker hopes that the drive will prove that fuel-cell vehicles are a viable alternative to traditional EVs and internal combustion vehicles and that lawmakers and businesses will respond by ramping up the infrastructure necessary to easily operate a fuel-cell auto.

The trip took 70 days and in many instances, the B-Class F-Cell vehicles had to rely on a mobile filling station for their hydrogen needs. Mercedes-Benz says that when fueling stations were available, it took as little as a few minutes to top off the onboard tanks.
