About the 2015 GMC Savana 3500

First generation, late-cycle year after the major 2003 refresh.

GMC positions the Savana 3500 as a straightforward heavy-duty full-size van for people-hauling or work duty. Its core appeal is simple: proven rear-wheel-drive hardware, V8 power, strong towing ability, big interior volume, and lots of body and seating configurations. Compared with newer rivals it is more old-school, but that simplicity is part of the draw for fleets, shuttle operators, churches, and businesses that want a durable van with familiar controls and easy upfit potential.

The 2015 Savana 3500 ranges from no-frills cargo vans built for trades and commercial equipment to LS and LT passenger vans aimed at shuttle and group transport. Extended cargo models provide up to 313.9 cubic feet of space, while diesel versions use a 6.6-liter Duramax turbo-diesel V8. Passenger-focused LT models add rear heating and air conditioning, cloth upholstery, carpeting, keyless entry, and cruise control.
