Barnhart (United States) - AllCarIndex

Barnhart was an American automobile brand established in 1905 by H. F. Barnhan in Warren, Pennsylvania. The brand emerged from Barnhan's early automotive endeavors, which began in 1897 while he was studying dentistry. He built his first two cars in collaboration with his father-in-law, C. D. Betts, before officially launching the Barnhart automobile.

The Barnhart automobile was notable for its large tourer design, equipped with a 44-horsepower four-cylinder engine. It featured an innovative automatic control system that allowed for the deactivation of one or more cylinders, a concept that would later be revisited in Cadillac's 4-6-8 system in the 1980s. Despite its advanced features, the Barnhart was short-lived, remaining on the market for only one year before Barnhan returned to his dental practice. The vehicle was also referred to as the Warren, named after its hometown.
