GMC Hummer EV SUV Towing Capacity
The GMC Hummer EV SUV is rated to tow 7,500 lb — standard, with no add-on trailering package needed, and the same rating as the Hummer EV pickup. Expect roughly 156 miles of real-world range behind a box travel trailer near that rating.

GMC Hummer EV SUV towing capacity specs
GMC gives the Hummer EV SUV a 7,500 lbmaximum conventional tow rating as standard equipment — there's no optional package gating the number. 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
- Recommended tongue weight: 10–15% of the loaded trailer (750–1,125 lb at the rating)
- Peak DC fast charge: 350 kW
- Onboard AC charging: 19.2 kW — useful for topping up overnight at a campsite hookup
The headline is curb weight and consumption. The Hummer EV SUV 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 most EVs — which is why the 7,500 lb rating is rarely the number that limits a trip. Range is.
Range impact while towing
The SUV's 311 miEPA figure assumes an empty truck on flat ground in mild weather. Towing changes all three at once, and the loss is dominated by aerodynamics: a box-shaped trailer has a frontal area several times the truck's, so wind drag — not trailer weight — sets your real range. Every row below holds the speed at 65 mph and changes only the load.
| Load | Weight | Towing range* (65 mph) |
|---|---|---|
| Teardrop / low camper | 1,500 lb | ~230 mi |
| Boat + trailer | 3,500 lb | ~205 mi |
| Open utility / car hauler | 5,000 lb | ~189 mi |
| Travel trailer (box) | 7,000 lb | ~157 mi |
| Tall box at max rating | 7,500 lb | ~146 mi |
*Estimates from EVMath's towing model (aerodynamic drag + trailer weight, calibrated against independent electric-truck road tests) at a steady 65 mph in mild weather. Cold, hills, and headwinds lower every figure.
The practical read: near the 7,500 lb rating behind a box trailer the SUV tows about 156 miles, so a 10–80% DC fast-charge returns roughly 109usable miles per stop. Route around chargers you can reach without unhitching — a Hummer plus a long trailer often can't fit a stall laid out for cars.

Hummer EV SUV vs Truck towing comparison
The most common question about the SUV is how it stacks up against the Hummer EV pickup for towing. The short answer: they tow the same weight. GMC rates both body styles at 7,500 lb maximum conventional towing, with the trailering hardware standard. What differs is everything around the trailer — payload, cargo format, and how the truck behaves behind a big load.
| Hummer EV SUV | Hummer EV Pickup | |
|---|---|---|
| Max tow rating | 7,500 lb | 7,500 lb |
| Cargo format | Enclosed rear cargo area | Open pickup bed |
| Wheelbase | Shorter — tighter, easier to maneuver | Longer — more settled behind a tall trailer |
| Best for | Enclosed gear, boat ramps, family + trailer | Bed hauling, higher payload, long highway tows |
The 7,500 lbrating is GMC's published maximum for both body styles. EVMath's verified spec data covers the SUV; the pickup shares its tow rating. Wheelbase and payload differences are structural, not capacity differences.
So pick by body, not by tow number. If you carry enclosed gear or want the more maneuverable truck for boat ramps and campsites, the SUV is the one — and it tows exactly as much as the pickup. If you need an open bed and the highest payload for the tongue weight plus cargo, the pickup's longer wheelbase edges it. For the pickup's deeper towing breakdown, see the GMC Hummer EV towing capacity guide, and for how both compare to the R1T and F-150 Lightning, the best EVs for towing ranking.
Best trailers for the Hummer EV SUV
The SUV can pull anything up to 7,500 lb, but the trailer's shape decides how far you go between charging stops. Ranked by towing range, the trailers that suit the Hummer EV SUV best are the low, slippery ones — they leave you the most usable miles.
| Rank | Trailer type | Towing range* (65 mph) |
|---|---|---|
| 1 | Teardrop / low camper (1,500 lb) | ~230 mi |
| 2 | Boat + trailer (3,500 lb) | ~205 mi |
| 3 | Open utility / car hauler (5,000 lb) | ~189 mi |
| 4 | Travel trailer (box) (7,000 lb) | ~157 mi |
| 5 | Tall box at max rating (7,500 lb) | ~146 mi |
*Estimated with EVMath's towing model at 65 mph in mild weather. Every trailer above is within the 7,500 lb rating; the ranking reflects range, not whether the SUV can pull it.
The takeaway: a teardrop, a boat, or a low utility trailer keeps the Hummer EV SUV in usable-range territory, while a tall box travel trailer or toy hauler turns it into a short-hop tow vehicle — great for campsites within ~150 miles each way, tiring for cross-country hauls. Match the trailer to the trip, and lean aerodynamic whenever you can.
Gear we'd look at
Hummer EV SUV 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 SUV 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 trailer near 7,500 lb 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 SUV stay hitched and still reach the plug.

Frequently asked questions
What is the GMC Hummer EV SUV towing capacity?+
The GMC Hummer EV SUV is rated to tow 7,500 lb. That rating is standard equipment — no extra trailering package is required to reach it. It covers most travel trailers, boats, and car haulers, though the SUV's enormous curb weight and 64 kWh-per-100-mi consumption mean the practical limit you hit first is range, not the rating.
Is the Hummer EV SUV tow rating the same as the Hummer EV pickup?+
Yes. GMC rates both the Hummer EV SUV and the Hummer EV pickup at 7,500 lb maximum conventional towing. Choosing between the two body styles is about payload, bed vs. enclosed cargo, and wheelbase — not towing capacity, which is identical. The pickup's longer wheelbase makes it marginally more settled behind a tall trailer at highway speed; the SUV's shorter body is easier to maneuver and park with a trailer attached.
How far can the Hummer EV SUV tow on a single charge?+
Plan on roughly 156 miles behind a box travel trailer near the 7,500 lb rating. The SUV's EPA range is 311 mi, and a boxy trailer at 65 mph cuts that by about half. A small, aerodynamic trailer costs far less range; a tall travel trailer at 70+ mph costs more. Because the Hummer already uses 64 kWh per 100 miles empty, it starts the towing-efficiency math from behind most EVs.
Does the Hummer EV SUV need a trailer brake controller to tow?+
For any trailer with its own electric brakes — which legally means most trailers over roughly 3,000 lb in the majority of US states — yes. GM's Ultium platform ships the Hummer EV SUV with an integrated trailer brake controller and trailer sway control, so you don't add an aftermarket unit; you wire the trailer's 7-pin connector and set the gain. Confirm your state's trailer-brake weight threshold before your first trip.
What are the best trailers for a Hummer EV SUV?+
Light, low, aerodynamic trailers. A teardrop camper or a boat on a trailer keeps towing range usable (230–205 miles), while a tall box travel trailer drops it toward 146 miles. The SUV can pull anything up to 7,500 lb, but the trailer's shape decides how often you stop to charge — so the best match is a shape that punches a small hole in the air.
