The Nash 600 is an automobile that was manufactured by the Nash-Kelvinator Corporation of Kenosha, Wisconsin for the 1941 through 1949 model years, after which the car was renamed the Nash Statesman. The Nash 600 was positioned in the low-priced market segment.[5] The '600' name comes from the car's ability to go 600 miles (970 km) on one tank of gasoline. Introduced for the 1941 model year, the Nash 600 became the first mass-produced unibody constructed car built in the United States.
