By , editorUpdated How we work out these numbers

The EPA rates the 2025 GMC Hummer EV Pickup 3X at 312 miles combined and 65.1 kWh per 100 miles measured at the wall, which is 52 MPGe. It is the least efficient car in this database. City and highway split 343 and 274 miles, a 20 per cent drop on the highway.

Those figures come from the regulator and are used in the comparison tables, the efficiency and range rankings and the per-state charging costs on this site. The rest of the record is not yet sourced: usable battery capacity, DC peak power and the 10–80 per cent charging time have no published figure credited here, so this page does not state them. They will appear when they can be credited to a named source, and not before.

Range & efficiency

EPA, WLTP and CLTC are different tests, not different opinions about one number. They sit side by side here and are never converted into one another.

Cost of ownership

Prices are sourced separately per market. A US price and a European price are two different market prices, not one price at an exchange rate, so this site never converts between them.

Safety & risk

Crash ratings come from the testing bodies. The battery safety score is our own composite and its formula is published on the methodology page.

Recall history notes24V320000 (electrical system:wiring): The electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a loss of drive power. | 23V367000 (electrical system:propulsion system:traction battery): Certain connections within the high-voltage battery pack may be out of position or incorrectly welded, which can cause a loss of drive power. | 22V771000 (electrical system:propulsion system:traction battery): The high voltage battery pack enclosure may not be properly sealed, allowing water to enter the pack.

Projected battery capacity

Projected straight-line from 2.7% a year — the published rate for this vehicle class, not a measurement of this car. Nobody releases per-model degradation data: the one fleet dataset large enough to matter anonymises the models. Capacity loss is driven as much by calendar age as by mileage, which is why it is reported per year rather than per kilometre. Real packs vary with climate, how long the car sits at a high state of charge, and how much of its charging is done at high-power DC.
