GMC, formerly known as GMC Truck, is a brand name used on trucks, vans, and SUVs marketed in North America and the Middle East by General Motors. In January, 2007, GMC was GM's 2nd largest selling light vehicle division after Chevrolet, ahead of Pontiac.
In 1901, Max Grabowski established a company called the ''Rapid Motor Vehicle Company'', which developed some of the earliest commercial trucks ever designed. The trucks utilized one-cylinder engines. In 1909, the company was purchased by General Motors to form the basis for the General Motors Truck Company, from which GMC Truck was derived.
Another independent manufacturer purchased by GM that same year was Reliance Motor Car Company. Rapid & Reliance were merged in 1911, and in 1912 the marque ''GMC Truck'' was first shown at the New York International Auto Show. Some 22,000 trucks were produced that year, though GMC's contribution to that total was a mere 372 units.
In 1916, a GMC Truck crossed the country from Seattle to New York City in thirty days, and in 1926, a 2-ton GMC truck was driven from New York to San Francisco in 5 days and 30 minutes. During the Second World War, GMC Truck produced 600,000 trucks for use by the U.S. military.
In 1925, GM purchased the controlling interest in Yellow Coach, a bus manufacturer based in Chicago, Illinois which was founded by John D. Hertz. After purchasing the remaining portion in 1943, GM renamed it GM Truck and Coach Division, and it manufactured transit and inter-urban buses in Canada and the United States until the 1980s. GM faced increased competition in the late 1970s and 1980s and stopped producing buses soon after. In 1987, GMC later sold their bus models to Transportation Manufacturing Corporation (also under Motor Coach Industries in Canada) and later NovaBus.
GMC currently manufactures SUVs, pickup trucks, vans, light-duty trucks, and medium-duty trucks. In the past, GMC also produced fire trucks, ambulances,
