Fuel Tank Capacity by Vehicle

What this tank size ranking shows

This chart ranks 51 models by tank size, from the 2019 Toyota Tundra at 38 gal down to the 2026 Ford Maverick at 13.8 gal. The median entry records 21 gal, and the middle half of the field falls between 18.6 and 26 gal — a useful reference point, because a figure inside that band is ordinary for the segment rather than remarkable.

Measured on each brand's strongest entry, Toyota leads with the Tundra at 38 gal, followed by Ford (F-350, 34) and Chevrolet (Suburban, 31). 14 manufacturers appear in the ranking overall, so tank size at this level is not the property of any single badge.

Each model appears once, represented by its best-performing configuration, with model years running from 2015 to 2026 and 0 entries drawn from the 2027 model year. Figures come from EPA and NHTSA publications rather than manufacturer marketing, and a model missing from the list is one with no published measurement for this specification — not one that scored zero. Open any row for the full year-by-year record of that vehicle, including the configurations that did not top its own range.
