Short for "Universal Motor Gerat," which translates from German to English as the "Universal Motor Device," the Unimog lives up to its name by taking on the toughest terrain, thanks to its off-road capability. So much so, that the Unimog 5000 has served as the main mode of transport for tourists who want to enjoy the sights of the famous lava field of the famous Torre del Filosofo.

Getting there can be quite a challenge, but climbing 9629 feet above sea level and traveling through the rough tracks and ash fields of Europe's highest active volcano is not a problem for the Unimog. It's equipped with a flexible ladder frame, all-wheel drive with differential locks in both portal axles, and a central tire inflation system. Tourists sit comfortably inside, thanks to the bus body that it wears atop its frame.

A second Unimog, a U550L, also works dutifully on the mountain by clearing snow and ash from the tracks. But Mount Etna isn't the only place where Unimogs are used: the ultimate off-roaders are used for fire services, disaster control, and expedition support.
