About GMC
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.
History
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.
