8. Amphicar Model 770
For decades, engineers toyed with the idea of floating cars, vehicles that drivers could use on the water as well as on the roads. However, most of them decided it was not worth investing in running or floating prototypes, so they abandoned the idea, except for the Amphicar.
The Amphicar was a German-made half-car, half-boat they produced from 1961 to 1965. Since it was so popular in the states, they sold over 3,500 of them. The power came from a diminutive 1.2-liter four-cylinder engine that powered not only the rear wheels but also the propeller they mounted in the back. On land, the Amphicar could achieve up to 75 mph and on the water, it could do seven knots. To be perfectly honest, the Aphicar wasn’t much of a boat and wasn’t much of a car, either.
