The Amphicar Model 770 is an amphibious automobile, launched at the 1961 New York Auto Show, manufactured in West Germany and marketed in the United States from 1961-1967, with production having ended in 1965.
Designed by Hanns Trippel, the amphibious vehicle was manufactured by the Quandt Group at Lübeck and at Berlin-Borsigwalde, with a total of 3,878 manufactured in a single generation.
A descendant of the Volkswagen Schwimmwagen, the Amphicar offered only modest performance compared to most contemporary boats or cars, featured navigation lights and flag as mandated by Coast Guard — and after operation in water, required greasing at 13 points, one of which required removal of the rear seat.
The Amphicar name is a portmanteau of "amphibious" and "car".
