The Soybean car (it was a prototype) was a vehicle that Henry Ford introduced it in 1941. The special thing was that the car was built with agricultural plastic. Although the formula used to create the plasticized panels has been lost, it is conjectured that the first iteration of the body was made partially from soybeans and hemp. Unfortunately the car has been destroyed.
There were three reasons why Henry Ford built this car.
1. Ford was looking to integrate industry with agriculture;
2. Ford claimed that his plastic made these cars safer than normal metal cars;
3. Ford wished to make his new plastic material a replacement for the metals used in normal cars. A side benefit would have been easing of the shortage of metal during World War II.
