General Motors GMC – other models: the collective page of pick-ups, SUVs and vans outside the named ranges, from Sierra and Yukon to Vandura and Safari, four- to ten-cylinders of 2.4 to 8.0 litres
This page gathers the GMC commercial vehicles the register could not assign to a named range – General Motors' truck and pick-up brand, which grew out of the GMC Truck Company in 1912 and to this day offers its own equipment lines alongside the mechanically related Chevrolet models. The type logic follows GM's modular system: Sierra denotes the pick-up range (sister model to the Chevrolet Silverado), Yukon and the extended Yukon XL the full-size SUVs on pick-up basis, Vandura the classic box van of the 1970s to 1990s, Safari the compact van, Canyon the smaller pick-up and Acadia the crossover SUV; suffixes such as Denali mark the luxury trim. A few models in the stock also carry, because of shared platforms and import routes, the badges of other GM-related brands.

The register lists here 41 versions from four- to ten-cylinders of 2,350 to 7,990 cm³, unladen weights from 1,337 to 3,015 kg, gross weights from 2,217 to 3,500 kg, lengths from 4,900 to 6,150 mm and widths from 1,720 to 2,530 mm.
GMC is one of the established pick-up and SUV brands in North America and positions itself there as a somewhat more upmarket alternative to the technically related Chevrolet line-up; in Europe the brand is present only through importers and the used market.
On used examples, rust on frame and load bed, the condition of the automatic transmission and four-wheel drive, brakes and suspension count, and on the V8 engines the condition of ignition and injection; parts for the younger model years run through the GMC network, for older models through the North American classic-parts market.
