Amphicar Technical Specifications


The Amphicar is the only amphibious civilian vehicle ever put into commercial production. The machines trace their ancestry to the Wehrmacht’s Schwimmwagens, Ferdinand Porsche’s VW-based creation for Hitler’s Third Reich.

After the war, a company backed by the Quandt family (which also owned a controlling share of a then-tiny German car company BMW) produced a civilian amphibious vehicle that took up where the stark military iteration left off.

Unlike wooden or fibreglass boats, Amphicars have no natural buoyancy. If the convertible top and windows are down, an errant wake or sudden waves can turn a swimmer into a drowner.

And heaven help the passengers who forget where they are and open a door. No wonder Amphicars have a secondary door-snugging handle to guard against this distinctly unnautical behavior.

During seven years of operation, Amphicar built 3878 Model 770’s.
