Willys is an American automobile manufacturer known for producing rugged vehicles, particularly during the mid-20th century. Founded in 1908, the company gained fame for its Willys MB model, which was widely used by the U.S. military during World War II. This vehicle is often credited as a precursor to modern SUVs. After the war, Willys transitioned to civilian vehicles, including the Willys Jeep, which became popular for its off-road capabilities. The brand eventually evolved into Kaiser Jeep Corporation and later became part of Chrysler, but its legacy in automotive history remains significant.
