M.A.T.T. (Monospace Amphibie Tout-Terrain) by French company TWI (Truck Werks Industries). It's an all terrain, amphibious vehicle based on Unimog.
Not sure about the year though. As far as I can see, it can still be ordered. In 2007 it had a world wide launch which was in fact a 35000 km trip from Washington to Russia.
