GMC Trucks

GMC as a truck brand was created out of a merger of the Reliance Motor Car Company and the Rapid Motor Vehicle Company within General Motors. GMC as a brand was officially introduced in 1912 at the New York International Auto Show. 

In 1912, GM built about 20,000 trucks.  Prior to the time of unveiling the GMC brand, trucks from GM were produced by both the Reliance and the Rapid companies. By 1913 all GMC truck production was performed at the Rapid Motor Vehicle Company plant in Pontiac, Michigan. Three years later in 1916 General Motors officially created the GMC Truck Division.

GMC trucks were usually sold by GM dealerships that also offered Buick, Pontiac or Oldsmobile models. The Chevrolet truck was sold exclusively by Chevrolet dealers. While the GMC and Chevrolet trucks may at times look identical there are differences in the trucks, some significant over during the latter years.

GMC did quite a lot of business with the military during World War Two. An interesting fact from this period is that the first HydraMatic transmission GMC vehicle was made for the military in 1944. Another fact is that GMC frames were built with heavier gauge steel than Chevy trucks.
