The Oakland Motor Car Company was founded in 1907 in Pontiac, Michigan, by Edward Murphy, a manufacturer of horse-drawn carriages. The following year, another former buggy company executive, William C. Durant, founded General Motors in Flint, Michigan, as a holding company for the Buick Motor Company. GM soon bought other automakers, including Oldsmobile and Cadillac. In 1909, Oakland became part of GM. The first model made its debut as the Oakland Four from 1909 until it was replaced by the Oakland Six in 1916. In 1926 the Pontiac Series 6-27 was introduced as a junior brand to Oakland, which featured a six-cylinder engine. The Pontiac was more popular than the senior brand and became its own GM division when Oakland was canceled in 1931.
It was named after the famous Odawa chief, who had also given his name to the city of Pontiac, Michigan, where the car was produced. Within months of its introduction, Pontiac was outselling Oakland. Body styles offered included a sedan with both two and four doors, Landau Coupe, with the Sport Phaeton, Sport Landau Sedan, Sport Cabriolet, and Sport Roadster. As a result of Pontiac's rising sales, versus Oakland's declining sales, Pontiac became the only companion marque to survive its parent, with Oakland ceasing production in 1932.
Pontiacs were also manufactured from knock-down kits at GM's Japanese factory at Osaka Assembly in Osaka, Japan, from 1927 until 1941.
