1964 Amphicar 770 – Exterior and Interior – Retro Classics Stuttgart 2022
A production car that could enter the water directly from a boat ramp was not a concept study in 1964—it was the Amphicar 770. Built in Germany and sold internationally, it combined conventional road engineering with marine propulsion. Few vehicles of the 1960s attempted such a literal fusion of car and boat.
Technical Details
The 1964 Amphicar 770 was developed by German engineer Hans Trippel and manufactured by the Industrie-Werke Karlsruhe (IWK). It used mechanical components sourced largely from the Triumph Motor Company, including a 1,147 cc inline four-cylinder engine also found in the Triumph Herald.
The water-cooled engine produced approximately 43 bhp and was mounted at the rear. On land, power was transmitted to the rear wheels through a four-speed manual gearbox. For marine operation, a separate gear selection engaged twin nylon propellers mounted beneath the rear bumper. This dual-drive arrangement allowed the Amphicar to operate both as a conventional rear-wheel-drive car and as a small motorboat.
The body was constructed from steel and designed as a watertight hull. Door seals and reinforced sills were critical to maintaining buoyancy. Suspension consisted of independent front suspension and a rear swing-axle setup. Braking was by hydraulic drum brakes. On land, the Amphicar achieved a top speed of approximately 110 km/h (around 70 mph), while in water it could reach speeds of about 11 km/h (approximately 7 knots). The model designation “770” refers to these approximate speeds—70 mph on land and 7 knots on water.

Design
Visually, the Amphicar 770 resembled a compact 1960s convertible, with modest tailfins and simple chrome detailing reflecting contemporary styling influences. The front featured round headlamps and a horizontal grille, while the rear concealed the twin propellers beneath the bumper.
The body’s shape was dictated not only by automotive considerations but also by hydrodynamics. The hull-like underbody and sealed construction allowed the vehicle to float without additional flotation devices. The convertible soft top was essential, as it reduced weight and simplified entry and exit when docked.
Inside, the dashboard combined automotive and marine instrumentation. In addition to a speedometer for road use, a separate marine throttle control and propeller engagement lever were installed. The cabin materials were selected with water exposure in mind, though owners still had to take care to dry and maintain the interior after aquatic use.
Historical Significance
The Amphicar 770 was produced between 1961 and 1968, with the majority of examples exported to the United States. During the early 1960s, there was optimism that amphibious vehicles might find broader civilian applications, particularly for recreational use.
Despite its innovative concept, production numbers remained limited—approximately 3,800 units were built in total. Regulatory challenges, cost considerations, and the niche nature of amphibious transport restricted widespread adoption. Nonetheless, the Amphicar remains one of the very few amphibious passenger cars ever produced in series.
The 1964 model year falls within the peak production period and reflects the mature configuration of the vehicle. It demonstrated that amphibious capability could be integrated into a road-legal production car without compromising basic drivability.
Quirks and Pop Culture
The Amphicar’s ability to transition directly from road to water has made it a recurring curiosity at classic car shows and waterfront events. Owners often stage demonstrations by driving into lakes or harbors, emphasizing the vehicle’s dual identity.
Because of its rarity and novelty, the Amphicar has appeared in various films, television features, and promotional events as a symbol of 1960s engineering optimism. Its name and performance figures—70 mph on land and 7 knots on water—remain central to its identity.
Today, surviving examples are maintained by dedicated enthusiast groups, and parts support remains available through specialist suppliers. The Amphicar 770 continues to represent one of the most unusual intersections of automotive and marine engineering.
Display and preservation:
The vehicle was exhibited at the Retro Classics Stuttgart in 2022. This car show is one of the major events on the classic car calendar in Germany. In 2022, it took place across five exhibition halls. Visitors can enjoy special showcases, hunt for rare parts and books, and buy cars—both private sellers and dealers offer a wide range of classic and youngtimer vehicles. In 2022, there was a noticeable increase in low-mileage youngtimers and classic cars.
Conclusion
The 1964 Amphicar 770 combined a 1.1-litre Triumph-sourced engine, rear-wheel drive, and twin marine propellers within a watertight steel body. Capable of approximately 70 mph on land and 7 knots on water, it achieved a rare dual-function design in series production. Although it remained a niche product, the Amphicar stands as a distinctive example of 1960s innovation and remains one of the most recognizable amphibious cars ever built.
