Amphicar 770 – the car that took to the water
Two propellers, four wheels, and unusually important door seals
The Amphicar 770 was meant to turn the boat ramp into an ordinary intersection. The West German amphibious car never became a mass-market product, but its combination of a British engine, a buoyant steel body, and twin propellers makes it one of automotive history’s most charmingly eccentric designs.

A car with an extra way out
The Amphicar 770 from the 1961–1968 period is an open-top, four-seat amphibious car designed both to drive on roads and travel through water. Behind the project was German designer Hans Trippel, who had worked on amphibious vehicles long before this civilian model. Production took place in West Germany within the Quandt Group, with Deutsche Waggon- und Maschinenfabriken in Berlin among the companies involved.
The model was introduced in 1961 and aimed primarily at the USA. There was purchasing power there, along with plenty of lakes, ramps, and recreational boat owners who might be tempted by a car with a propeller. This was no military off-roader dressed in its Sunday best, but a recreational car intended to make the journey itself an outing.
The model name was almost a miniature instruction manual: 770 referred to roughly seven knots in water and 70 miles per hour on land. Those were claimed top speeds, not a promise that every launch would turn into a speed fest.
Around 3 878 examples were built. The dates do need a footnote, however: 1961–1968 is often used as the model’s lifespan, but production, sales of remaining inventory, and registration years do not always coincide. For an individual collector car, manufacturing records therefore need to be distinguished from its first registration.
A floating body, British machinery
At first glance, the Amphicar looks like an unusually tall little convertible. The fins, round headlights, and simple dashboard clearly belong to the early 1960s. But beneath that friendly face is a welded steel body that also serves as the boat’s hull.
The generous ground clearance made room for the specialized equipment needed for traveling through water. Two propellers sit beneath the stern, while the engine is mounted at the rear. The four-cylinder engine came from the Triumph Herald: fairly ordinary British machinery in a decidedly unusual German application. Using an established passenger-car engine meant the designers did not have to invent that part of the adventure, too.
The drivetrain, on the other hand, was specialized. A purpose-built transmission from Hermes distributed power to the rear wheels and the propellers. The wheels and propellers could operate simultaneously, which was important when the car needed to climb a ramp and become an ordinary road user again.
The door seals and additional locking mechanism were far more than details for keeping out the rain. They were part of the car’s basic ability to function as a watercraft. There was a bilge pump, too. On an ordinary convertible, a tired rubber seal can mean wet pant legs; here, the consequences were potentially much greater.
The steering wheel went along for the swim
The transition to water required preparation, not just a confident right turn at the swimming beach. Seals, locks, and the bilge pump needed to work, and a suitable entry point and the possibility of getting back out had to be assessed. A shoreline is not automatically a boat ramp, however optimistic the driver may be.
Once in the water, the driver continued to use the steering wheel. The front wheels acted as rudders, while the two propellers provided propulsion. There was no separate boat rudder. The design eliminated the need for a dedicated steering device, but wheels are not as effective in water as a proper rudder.
The Amphicar was intended for recreational use on sheltered waters, not as a substitute for a seagoing motorboat. Its ability to swim did not make it immune to the effects of load, weather, and waves, either. Its main appeal was instead the ability to keep going where the road ended, without a trailer or a change of vehicle.
After the swim came maintenance. Lubrication and inspection of parts that had been underwater were part of using the car. Salt water made the risk of corrosion particularly troublesome. Anyone picturing nothing but an ice cream in one hand and the steering wheel in the other had missed part of the owner’s manual’s message.
A collector car with two kinds of condition
Today, the Amphicar is an established specialty collector car. A meaningful valuation, however, cannot be based solely on shiny paint and attractive seats. Collector value must be assessed for each individual example, taking into account documentation, originality, restoration quality, and working amphibious equipment.
The underside of the hull, welds, door seals, propeller-shaft seals, and transmission are key inspection points. A car can be drivable on the road without being safe to launch. When buying, any claim that it is ready for the water should therefore be backed up by an expert inspection, not the seller’s vacation photos.
That is also where the Amphicar’s appeal lies. As an ordinary car, there are simpler alternatives, and the same goes for boats. But few collector vehicles turn a perfectly ordinary boat ramp into the highlight of the trip.
