GMC
This massive corporation started in a small way. In 1903, William C. Durant took control of Buick and in 1908 founded the General Motors Company which absorbed a number of early car and truck makers. In 1911 the truck names were changed to GMC who acquired Chevrolet during World War I. Another merger followed in 1925 and another in 1943, each time increasing in size.
General Motors Corporation now has interests in many companies around the globe. In terms of truck manufacture its most important are Vauxhall, formerly Bedford in the U.K., Opel in Germany, Chevrolet and GMC in the U.S.A. and Isuzu in Japan.
There are also considerable numbers of other companies in which it has an interest. Many of its products are lightweight commercial vans and delivery trucks but the GMC Astro and General models are heavyweight American trucks par excellence.
The three-axle GMC General of the late Eighties is a bonneted design and under this feature is found a variety of big diesel engines including the Detroit, Cummins and Caterpillar which have outputs ranging between 268 and 470 bhp. Transmissions, too, are complex and massive - up to 15 forward gears can be selected.
The General will pull up to 65 tons gross combined weight (of trailer and tractor unit). The three- axle GMC Astro is a cabover design but comes with a similarly bewildering choice of engines and transmissions. The sleeper cab tilts to allow engine access and the tractor unit will cope with a gross combined weight of up to 45 tons.
