About the 2020 GMC Savana 3500

Long-running full-size Savana/Express van generation, late-cycle year; 2020 is a light-update year before broader 2021 powertrain revisions.

GMC positions the Savana 3500 as a simple, heavy-duty full-size van for businesses and organizations that need durability, payload, towing strength, and straightforward packaging more than modern styling or big-screen tech. In cargo form it is a work tool built around usable space and upfit potential. In passenger form it is a people mover for shuttle, church, school, or crew duty, with the 3500’s appeal centered on heavier-duty capability and available extended-body seating capacity.

The 2020 Savana 3500 remains a work-focused full-size van sold in cargo and passenger forms, with regular and extended wheelbases. Extended cargo vans provide up to 283.6 cubic feet of space, while extended passenger vans seat up to 15. LT passenger models add a more finished cabin plus forward collision alert and lane departure warning.
