GMC is a division of General Motors LLC that is known for its focus on trucks and commercial vehicles, although GMC also produces large passenger vehicles, such as GMC pickup trucks and GMC sport utility vehicles. Over the years, GMC has produced and sold commercial trucks, vans, buses, and military vehicles. GMC has consistently been one of the top-selling General Motors brands, despite its relatively tightly focused model lineup and a comparatively small global footprint. Many of GMC’s consumer vehicles are designed, engineered, and produced alongside identical or near-identical vehicles that are sold under General Motors’ Chevrolet brand, and, occasionally, the Cadillac luxury brand. GMC vehicles, including GMC sport utility vehicles, have been sold in the United States, Canada, Mexico, and the Middle East.

The GMC Jimmy is an example of a GMC SUV that has had an important influence on the brand. The history of the GMC Jimmy is tied closely to the Chevy Blazer and Chevy Tahoe, as well as the GMC Yukon. Chevrolet introduced the Blazer truck in 1969, and GMC followed with the Jimmy in 1970. Both vehicles were full size sport utility vehicles based on existing General Motors pickup trucks, resulting in full body-on-frame traditional SUV construction. Both the GMC version and the Chevy version of this vehicle were based on short wheelbase trucks, and, like the trucks, were available in rear-wheel-drive and four-wheel-drive configurations. General Motors also produced smaller versions of both vehicles. The Chevy Blazer was produced until 1995, and the GMC Jimmy was produced until 1992. These sport utility vehicles were assembled in General Motors production facilities around the United States, including Janesville, Wisconsin; Flint, Michigan; and Fremont, California. At that point, a new GMC sport utility vehicle took the Jimmy’s place, called the GMC Yukon, which was produced alongside the new Chevy Tahoe. Both models were essentially new generations of the old sport utility vehicles, although the platform was updated. The Yukon is still in production as a full size GMC sport utility vehicle. It has since been joined by the GMC Acadia, which went into production in 2006, and the GMC Terrain, which began production in 2009. As compared to full size GMC SUVs, these vehicles slot a little lower in the hierarchy in terms of price and features. The Terrain is a mid size crossover SUV that is similar to the Chevy Equinox and the discontinued Pontiac Torrent, whereas the Acadia is a full size crossover that shares a platform with the Chevy Traverse and Buick Enclave.
