GM under Durant's leadership acquired Oldsmobile later in 1908. The next year, he brought in Cadillac, Cartercar, Elmore, Ewing, and Oakland (later known as Pontiac). In 1909, General Motors also acquired the Reliance Motor Car Company of Owosso, Michigan, and the Rapid Motor Vehicle Company of Pontiac, Michigan, the predecessors of GMC Truck. A Rapid became the first truck to conquer Pikes Peak in 1909. In 1910, Welch and Rainier were added to the ever-growing list of companies controlled by GM.
