GMC Hummer EV SUV: what to know
The 2025 GMC Hummer EV SUV is a 5-seat three-row SUV with an EPA range of 311 mi from a 205 kWh battery, starting at $105,545 MSRP.
DC fast charging peaks at 350 kW but a 10–80% top-up takes around 42 minutes, so this is happiest as a home-charged daily driver rather than a frequent road-tripper.
It uses 64 kWh per 100 miles, so at the US-average home rate of $0.16/kWh it costs about 10.2¢ per mile to fuel — roughly $1,331 a year at 13,000 miles.
GMC Hummer EV SUV Towing Capacity
- Max towing capacity
- 7,500 lb
- Tow package
- Standard equipment
- Range towing near max (est.)
- ~156 mi (≈50% loss)
The 2025 GMC Hummer EV SUV is rated to tow up to 7,500 lb — enough for a midsize travel trailer, a loaded open car hauler, or a fishing/wakeboard boat on a tandem-axle trailer. The hitch and tow tech are standard equipment, so the full rating is available without an upcharge.
Expect a real-world range hit when you actually hook up a trailer near that rating: independent road tests of EVs in this class consistently land around a 50% reduction at or near max tow, which would drop the GMC Hummer EV SUV's 311 mi EPA range to roughly 156 mi of usable range between charges.
Plan DC-fast-charge stops more frequently than you would unloaded — 350 kW peak helps, but heavy trailers also tax thermal limits, and pull-through stalls remain rare on most networks.
Towing capacity from the manufacturer. Range-loss figures marked “est.” are estimates based on corroborated third-party road tests at or near max tow; real-world results vary with trailer aero, grade, speed, and weather.
