The Willys Americar was a line of automobiles produced by Willys-Overland Motors from 1937 to 1942, either as a sedan, coupe, station wagon or pickup truck.

When Joseph W. Frazer joined the company in 1938 he decided that a modern-looking and cheap compact car was the answer for the struggling Willys.

[2] As war broke out, civilian production was abandoned by all US motor companies, in order to assist the military, and the Americar was no exception.

After the end of the war they managed to secure the trademark on the Jeep name, and the much higher sales of its civilian CJ version kept the Toledo firm from resurrecting the prewar models, sealing the fate of the Americar.

Despite failed attempts in 1940 and 1945 (both times with Frazer's 6/66 prototype), the 1942 Americar would be Willys-Overland final "civilian" passenger car model until the Willys Aero, ten years later.
