GMC’s full-size van sells in fewer numbers than the similar Chevrolet Express but attracts a loyal clientele. Along with its full-size rivals from Dodge and Ford, the rear-drive truck-based van has been on the market for decades.

Like Chevrolet, GMC produces both a cargo van and a passenger model, in two sizes and three capacity ratings: G1500 (half-ton), G2500 (three-quarter-ton) and G3500 (one-ton). Two regular trim levels are offered, the base SL and upscale SLE. General Motors and the Lear Corp. have been working together on a Savana SLT luxury van, which would be comparable to the new Chevrolet Express LT.

Built on an extended, 155-inch wheelbase, the 2500/3500 vans can seat 12 to 15 occupants. A new 8.1-liter 8100 V-8 engine has replaced the 7400 V-8 for 2001. Otherwise, changes are primarily technical and are said to boost engine and transmission efficiency. Savana vans also are provided to conversion companies in unfinished form.
