2026 GMC Hummer EV towing specs
GM gives the Hummer EV a 7,500 lbmaximum conventional tow rating as standard equipment — there's no optional package gating the number the way Ford gates the F-150 Lightning. Behind that rating sits a 205 kWh Ultium pack and an 800-volt architecture that DC fast-charges from 10–80% in about 42minutes when you're not towing.
- Max tow rating: 7,500 lb (standard)
- Battery: 205 kWh usable
- EPA range (unladen): 311 mi
- Energy use (unladen): 64 kWh per 100 mi — among the highest of any EV on sale
- Peak DC fast charge: 350 kW
- Onboard AC charging: 19.2 kW
The headline is the curb weight and consumption. The Hummer EV is one of the heaviest passenger vehicles ever built, and it already burns 64 kWh per 100 miles empty. Hang a trailer off the back and the towing-efficiency math starts from a worse place than a Lightning or R1T — which is why its real-world towing range lands close to theirs despite a lower rating.
Hummer EV vs Rivian R1T vs F-150 Lightning: towing compared
| Vehicle | Max tow | EPA range | Towing range* | Tow package |
|---|---|---|---|---|
| GMC Hummer EV SUV | 7,500 lb | 311 mi | ~156 mi | standard |
| Rivian R1T Max | 11,000 lb | 410 mi | ~205 mi | standard |
| Ford F-150 Lightning ER | 10,000 lb | 320 mi | ~160 mi | optional |
*Towing range is each model's EPA range reduced by its corroborated range-loss estimate near the max rating (about 50% for all three), based on independent road tests. Lighter, more aerodynamic trailers cost less; tall travel trailers at 70+ mph cost more.
The Hummer EV has the lowest rating of the three, but the smallest gap shows up in real-world towing range — because the R1T and Lightning give back much of their rating advantage in the higher range they start from. If your trailers stay well under 7,500 lb, all three tow them; the deciding factors become charging-stop access and how far you go between stops.
Real-world towing range impact
The Hummer EV's 311 miEPA figure assumes an empty truck on flat ground in mild weather. Towing changes all three of those assumptions at once. Independent electric-truck tow tests consistently show a 40–60% range cut near the maximum rating, and the loss is dominated by aerodynamics: a box-shaped travel trailer has a frontal area several times the truck's, so wind drag — not trailer weight — sets your real range.
- Small, low trailer (boat, jet skis, utility): expect the smallest hit — often only a 30–40% cut.
- Mid-size travel trailer at 65 mph: roughly 156 miles between charges.
- Tall travel trailer or toy hauler at 70+ mph: can drop below 120 miles, especially in cold weather.

Hummer EV towing setup requirements
The Hummer EV comes better-equipped for towing out of the box than most buyers expect, but a 7,500 lb trailer still puts you into heavy-duty hitch and braking territory. Here's what you actually need.
Hitch class
A loaded trailer near 7,500 lb is Class IV. Use a receiver, ball mount, and hitch ball each rated at or above your loaded trailer weight (a 2-5/16" ball is standard at this weight). Keep tongue weight in the 10–15% range and within the receiver's vertical-load rating. On tall travel trailers, a weight-distribution hitch settles rear squat and sharpens stability — worth it above ~5,000 lb.
Brake controller
GM's Ultium trucks include an integrated trailer brake controller, so you don't need to add an aftermarket unit — wire the trailer's 7-pin connector and set the gain. Most US states require working trailer brakes above roughly 3,000 lb, which covers nearly any trailer you'd tow at this rating. The truck also includes trailer sway control. Confirm your state's exact weight threshold and your trailer's brake type before your first trip.
Charging access while towing
The setup detail people forget: most DC fast-charging stalls are laid out for cars, and a Hummer EV plus a long trailer often can't pull in without unhitching. Plan stops in advance around pull-through stalls, and carry a portable Level 2 charger so RV-park pedestals become a backup. Towing means charging more often, at more kinds of plugs.
Is the Hummer EV good for towing?
For local and regional towing, yes. The standard 7,500 lb rating, enormous torque, integrated trailer brake controller, and sway control make the Hummer EV stable and genuinely easy to tow with. Where it struggles is distance: about 156 miles between charges near the rating, the highest unladen consumption of any mainstream EV, and a footprint that makes fast-charging stalls hard to use with a trailer attached.
Buy it for towing if your trips are boat ramps, job sites, and campsites within roughly 150 miles each way. Look elsewhere — or plan on a charging stop every couple of hours — if you tow a tall trailer cross-country. The Rivian R1T and F-150 Lightning Extended Range carry higher ratings and start from more range, so they hold a real-world towing-distance edge despite similar percentage losses.
Gear we'd look at
Hummer EV towing gear: hitch, charging, and campground hardware
Towing eats range, so the calculus changes — you charge more often, at more places, and you need hardware that copes with hookup variety. These categories cover what actually rides in the truck on a tow trip.
Class IV adjustable ball mount with 2-5/16" ball
Match the ball to your trailer coupler and weight rating
A 7,500 lb trailer is Class IV territory. An adjustable-drop ball mount levels the trailer and a 2-5/16" ball is the standard size at this weight. Confirm the stamped rating exceeds your loaded trailer weight.

Weight-distribution hitch with sway control
Settles rear squat on tall travel trailers
On a tall, heavy travel trailer near the 7,500 lb rating, a weight-distribution hitch restores steering feel and stability. Pair it with the Hummer's built-in trailer sway control for confident highway towing.

Portable Level 1/Level 2 charger with NEMA adapters
Turn RV-park and shop outlets into a charging stop
Towing means topping up wherever you can. A dual-voltage portable with NEMA 14-50, TT-30, and 5-15 adapters makes campground pedestals and dryer plugs usable when DC fast stalls can't fit the truck and trailer.

Heavy-duty 25–50 ft EV charging cable extension
Reach the pedestal without unhitching
RV-park L2 pedestals and many public chargers are positioned for cars, not a Hummer plus a long trailer. A heavy-gauge SAE J1772 extension lets the truck stay hitched and still reach the plug.

Frequently asked questions
What is the GMC Hummer EV towing capacity?+
The GMC Hummer EV is rated to tow 7,500 lb. That rating is standard — no extra trailering package is required to reach it, unlike the F-150 Lightning, which needs Ford's Max Trailer Tow Package for its top number. It's a lower maximum than the Rivian R1T (11,000 lb) or F-150 Lightning Extended Range (10,000 lb), but 7,500 lb still covers most travel trailers, boats, and car haulers.
How far can a Hummer EV tow on a single charge?+
Plan on roughly 156 miles near the max rating. The Hummer EV's EPA range is 311 mi, and independent road tests show electric trucks lose about half their range under a heavy, box-shaped trailer at highway speed. A small, aerodynamic trailer costs less; a tall travel trailer at 70 mph costs more. The Hummer is also one of the thirstiest EVs on sale (64 kWh per 100 mi unladen), so it starts the towing-efficiency math from behind.
Does the Hummer EV need a brake controller to tow?+
For any trailer with its own electric brakes — which legally means most trailers over ~3,000 lb in the majority of US states — yes. GM's Ultium trucks ship with an integrated trailer brake controller, so you don't need to add an aftermarket unit; you wire the trailer's 7-pin connector and set the gain. Always confirm your state's trailer-brake weight threshold and your trailer's brake type before towing.
What hitch do I need to tow 7,500 lb with a Hummer EV?+
A 7,500 lb trailer puts you into Class IV territory. Use a receiver and ball mount rated at or above your loaded trailer weight, and a hitch ball sized to the trailer coupler (commonly 2-5/16"). Budget tongue weight at roughly 10–15% of loaded trailer weight and keep it within the receiver's rating. A weight-distribution hitch is worth it on tall travel trailers to settle squat and improve stability.
Is the Hummer EV good for towing?+
It's capable but not efficient. The torque, integrated trailer brake controller, and standard 7,500 lb rating make it easy and stable to tow with. The catch is range: ~155 miles between charges near the rating, and DC fast-charging stalls that often can't physically fit a Hummer plus a long trailer. It's a strong choice for local and regional towing — boat ramps, weekend campsites under ~150 miles each way — and a poor one for cross-country hauls.
