Background
Hans Trippel's experiments with amphibious vehicles began in the 1930s, bearing fruit in wartime in the form of the Volkswagen based Schwimmwagen, more than 14,000 of which saw service with the German Army in WWII. Trippel revived the concept post-war with the Amphicar (originally called the Eurocar).
Necessarily of unitary construction, the cabriolet-style Amphicar was powered by a 70cu in (1,147cc) four-cylinder Triumph Herald engine mounted in the rear and driving the rear wheels.
A special transmission drove the two propellers that afforded a maximum cruising speed on water of around 6 knots (7mph), the top speed on land being around 70mph. No special steering gear was required for use on water, the car being steered in the normal way.
The design certainly worked, as demonstrated by a well-publicized stunt that saw an Amphicar successfully cross the English Channel from France to England in 1962.
Nevertheless, and despite the attractions of its dual capability, the Amphicar was not a commercial success. In what should have been its biggest market - the USA - the Amphicar was handicapped by the many difficulties involved in trying to comply with smog and safety regulations.
Demand for what was essentially a novelty vehicle never remotely approached the 20,000 units projected annually, only 3,000-or-so being constructed before production ceased in 1968.
