What is considered a GM vehicle?
A GM vehicle is any car, truck, or SUV made or marketed by General Motors or its current brands: Chevrolet, GMC, Buick, and Cadillac.
General Motors' four core brands drive the modern lineup, with Hummer operating as a GMC sub-brand for electric trucks and SUVs. Over the years GM has retired several brands and restructured others, notably selling Opel/Vauxhall in Europe and winding down Holden in Australia. The sections below explain what counts as a GM vehicle today and how the brand lineup has evolved.
Current GM brands that define the lineup
GM's present global brands are four, with Hummer positioned as a GMC sub-brand for its trucks and SUVs.
- Chevrolet
- GMC
- Buick
- Cadillac
Conclusion: The current GM lineup comprises vehicles sold under these four brands. Hummer functions as a GMC sub-brand for select models, particularly in the electric vehicle segment.
Historical or defunct GM brands
GM's history includes several brands that are no longer used in new-vehicle branding. The following names appear in historical contexts or on older vehicles rather than as ongoing brands.
- Pontiac
- Oldsmobile
- Saturn
- Saab (defunct GM stake; sold in 2010)
Conclusion: These brands illustrate GM's portfolio changes over time; they are not part of the current four-brand lineup.
Global market notes
In Europe, Opel and Vauxhall were GM brands until they were sold to Groupe PSA (now Stellantis) in 2017. In Australia, Holden's local manufacturing ended around 2017, and GM shifted toward importing vehicles under the Chevrolet and GMSV framework rather than maintaining the Holden brand for new models. The result is that the GM vehicle identity today centers on Chevrolet, GMC, Buick, Cadillac—and, where applicable, GMC Hummer models.
What this means for consumers
For buyers and observers, the practical takeaway is straightforward: a GM vehicle bears a Chevrolet, GMC, Buick, or Cadillac badge, or a GMC Hummer badge for the electric trucks and SUVs. Older GM-brand names remain relevant for historical context or used-vehicle identification but do not represent current production lines.
Summary
GM today centers on four brands—Chevrolet, GMC, Buick, Cadillac—with Hummer as a GMC sub-brand. Defunct brands such as Pontiac, Oldsmobile, Saturn, and Saab are no longer part of the current lineup, and Opel/Vauxhall and Holden have been divested or retired in their original form. In practical terms, a GM vehicle is a car, truck, or SUV branded by Chevrolet, GMC, Buick, Cadillac, or Hummer models under GMC.
