The REO Motor Car Company, founded by Ransom E. Olds, was one of the pioneering companies of the American automotive industry, renowned for its innovation and durability in both passenger and commercial vehicles. Throughout its history, it produced iconic models such as the Single and the Twin, which represented the brand's first single cylinder and twin cylinder cars, as well as the Four, which solidified the use of four cylinder engines. Later, models like The Fifth and the Model M refined the power and smoothness of the four cylinder engine, while the Speed ​​Wagon marked REO's entry into the truck and pickup segment. The company continued to innovate with the T-6, a six cylinder model that offered greater comfort, and the Flying Cloud, which combined durability and style during the 1920s and 30s. Finally, with the Royale, REO demonstrated its ability to compete in the luxury market, thus closing a remarkable chapter in the history of the American automobile. REO struggled to surive in the post WW2 era, and would eventually be purchased by the White Motor Company, and be merged with Diamond T Trucks to create Diamond REO Trucks in 1967, ending the REO name.
