2015 Chevrolet Express 3500: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2015 Chevrolet Express 3500 is a standard 120-volt front power outlet across cargo and passenger vans. This is otherwise a light-update year rather than a redesign, though passenger vans gained new radio choices and an 8-passenger layout, and some gasoline-only powertrain entries were dropped.
About the 2015 Chevrolet Express 3500
Second generation (2003-2026), late-cycle 13th model year with no major redesign for 2015.
Chevrolet positions the Express 3500 as a proven heavy-duty full-size van for work fleets and group transport. Cargo versions focus on durability, upfit friendliness, and straightforward access, while passenger versions are meant to move large groups in a simple, sturdy package. What sets the model apart is old-school V8 and diesel power, strong towing, and a tough full-length frame that still appeals to buyers who value durability and service familiarity over newer van packaging.
The 2015 Express 3500 remains a heavy-duty work and passenger van, with regular and extended bodies serving cargo, fleet, and shuttle duty. Cargo versions emphasize durable flooring and easy side-door access, while LT passenger vans add rear heating and air conditioning, cloth seats, carpeting, and keyless entry. Duramax diesel versions provide extra pulling power for heavier loads and trailer work.
