How much do things change in 60 years? Sometimes the best answer to that kind of question is a picture. Here you can see an original Unimog (right), built sometime between the start of production in 1948 and 1951, when Mercedes bought the operation in order to expand it enough to keep up with demand. On the left is a “60th Anniversary” Unimog design concept, celebrating not the actual birth of the Unimog, but its purchase by Mercedes. Needless to say, the contrast between the two is… breathtaking. And if you’re curious about the evolution of this hugely influential vehicle, if you can’t help wondering how it grew from a (relatively) tiny, spartan utility vehicle to a garish, Mercedes-starred behemoth.
