Carhartt Automobile Company was established in Detroit, Michigan, during the early 20th century, specifically between 1911 and 1912. The company was founded by Hamilton Carhartt, who was primarily known for his success in manufacturing work clothing, particularly overalls. Carhartt's transition into the automobile industry was marked by a claim of extensive manufacturing experience, although his background was not in automotive production.

The company produced two models of four-cylinder automobiles: the Junior, which had a power output of 25 horsepower, and the Four, which offered 35 horsepower. The Four was notable for its versatility, as it was available in six different body styles, ranging from a simple runabout to a more luxurious limousine. All models were priced uniformly at $2,250, reflecting a strategy to appeal to a broad market segment.

In 1912, Carhartt expanded its offerings by introducing a more powerful four-cylinder model rated at 50 horsepower, with prices ranging from $2,500 to $3,500. Despite the ambitious plans and diverse product lineup, the Carhartt Automobile Company had a brief existence and did not achieve lasting success in the automotive market.
