GMC vans and trucks up to 3.5 t (class N1) – collective page for the EU light-van class covering the Chevrolet sister programme: Sierra, Savana and Suburban as GMC versions, engines from 66 to 209 kW, gross weights up to 3.5 t
The EU vehicle class N1 covers light commercial vehicles up to 3.5 t gross vehicle weight; this page is a collective page built from registration data (Netherlands, Finland) bundling every GMC range recorded in that class. GMC (General Motors Truck Company) was founded in 1911/1912 and, as a standalone brand within General Motors, specialises in trucks and SUVs – technically largely identical to Chevrolet but with its own model names and usually a more upmarket trim level. The register holds the GMC counterparts to the Chevrolet ranges: Sierra (sister model to the Silverado pickup), Savana (sister model to the Express panel van) and Suburban versions, plus the top-of-range Denali trim.

The register lists 433 versions, with recorded outputs of 66 to 209 kW, displacements of 2,800 to 8,200 cm³ across 4 to 8 cylinders, kerb weights of 1,220 to 3,350 kg and gross vehicle weights of 1,514 to 3,500 kg; width ranges from 1,550 to 2,500 mm, length from 4,330 to 7,750 mm.
As Chevrolet's sister brand, GMC is a textbook example of how US manufacturers sell the same technical base under two brand names with different positioning – the displacement and cylinder-count ranges therefore largely match those of the Chevrolet N1 page.
On a used example, the same checkpoints apply as on the technically related Chevrolet models: corrosion on the frame and load bed, the condition of the V8 engines and their cooling system, the transfer case on four-wheel-drive versions, plus the provenance and registration history as a US import. Spare parts run through specialised importers, since GMC does not maintain a regular distribution network in Europe.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
