2018 GMC Savana 2500: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2018 GMC Savana 2500 is its new standard 4.3-liter V6 and 8-speed automatic, replacing the previous 4.8-liter V8 and 6-speed setup. The body and basic cabin carry over, so this is a mechanical update rather than a redesign.
About the 2018 GMC Savana 2500
2nd generation (2003-present), very late-cycle update year
The Savana 2500 is GMC’s old-school full-size van built around durability, simple controls, and job-focused flexibility. In cargo form it is meant to be an easy-to-upfit work van with straightforward access and strong towing capability. In passenger form it is a practical people mover for shuttle, church, and fleet duty. What sets it apart is its simple body-on-frame setup, multiple wheelbase and engine choices, and familiar commercial-vehicle feel rather than modern design or fancy tech.
The Savana 2500 remains a straightforward full-size van for cargo hauling or passenger duty. Cargo versions come in regular- and extended-wheelbase forms with durable flooring, tie-downs, LED cargo lighting, and up to 284.4 cubic feet of space. The LS seats 12, while the passenger-focused LT adds cloth upholstery, carpeting, rear air conditioning, remote locking, and cruise control.
