What are the changes between cars from 1940's and 1980's?
The majority of cars in the 1940's were rear wheel drive and carbureted. They did not have seat belts, air bags, antilock brakes. There were several odd ball front wheel drive cars and even less fuel injected gasoline powered cars, all made in Europe, and American vehicles with diesel engines had fuel injection.In the 1980's car manufactures began a large movement towards safer more fuel efficient vehicles. Cars came out with Rear Wheel Antilock braking systems, which greatly improved their stability. Primitive Supplemental Inflatable Restraint Systems became standard features on mid 80's cars. In another effort to improve safety, manufactures began building front wheel drive cars, which improve steering response, fuel efficiency, and stability. In a need to make cars emit lower emissions and be made more fuel efficient, the carburetor was replaced, first with the throttle body and then with port fuel injection. By 1989, carburetors were unavailable on any car except the 1989 Cadillac Brougham, which was the last carbureted vehicle to be produced in the United States.
