As far as I can tell, the Fiat 500 gained popularity all around the world after Fiat started producing the mini car in 1957 (it quickly attained cult status and is still around today). Now a Japanese man called Kogoro Kurata decided to transform his 1950s model into a retro bulldozer for some reason [JP].
Kurata says his bulldozer runs at just 3km/h max. But as you can see in the video below, the hybrid vehicle really works and looks pretty cool.
