GMC trucks 3.5–12 t (Class N2) – a collective page of GMC ranges by EU vehicle class: Suburban, Sierra, Silverado and Savana alongside historic military trucks, engine outputs 67 to 332 kW

Class N2 groups, under EU vehicle law, trucks with a gross vehicle weight of between 3.5 and 12 tonnes; this page accordingly bundles GMC models classified as such in Dutch and Finnish registration data. The register mainly features the heavy pick-up and SUV ranges Sierra and Suburban, plus the Savana van (GMC's counterpart to the Chevrolet Express) and, as a historic addition, the military all-wheel-drive CCKW-353 truck from the Second World War era, popularly known as the "Jimmy".

The register lists 218 versions with engine outputs of 67 to 332 kW, displacements of 2,695 to 7,485 cm³, four to eight cylinders, unladen weights of 2,300 to 9,940 kg and gross vehicle weights of 3,510 to 12,000 kg.

GMC positions itself as Chevrolet's sister brand, focused on higher-grade equipment on largely technically identical vehicles; the ranges recorded here cover almost the entire N2 payload class, from light pick-up to heavy Suburban SUV, and compete in the North American market with Ford and Ram.

On a used example, depending on the range, what counts is corrosion on the ladder frame and wheel arches, the condition of the automatic transmission and all-wheel drive, on diesel versions oil loss and engine mileage, and — on the historic military vehicles — the preservation state of the body and axles plus the limited parts supply through specialist vintage-vehicle dealers.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
