Try it

Will it pull your trailer?

Use the trailer's GVWR (on its VIN sticker) if you don't know what it weighs loaded — the dry weight leaves out water, propane and gear.

Yes, in every configuration

Across all 2 configurations in the maker's guide.

▲ top rating 12,000 lbs

  • Tongue weight ≈ 660 lbs — 10% of the loaded trailer, the figure Ford's towing guide uses (no more than 200 lbs up to 2,000 lbs). It counts against your payload, together with passengers and cargo.
  • ✓ up to 90% of the rating · ! 90–100% (little room for cargo, hills, wind — common advice, not a GMC rule) · ✕ over the rating.

Why the numbers differ

  • The body style counts too: Pickup is rated 2,000 lbs higher than SUV with everything else the same (Pickup). p. 21 ↗

  • Same top rating as the 2024 model (12,000 lbs).

In real life

What 12,000 lbs means in trailers

Ford's towing guide sorts trailers into four weight classes; the classes describe the trailer, so they apply to any tow vehicle. With the right configuration the HUMMER EV reaches:

  1. Class I✓ Yes

    up to 2,000 lbs

    Small folding camping trailers and trailers for small boats, motorcycles and snowmobiles.

  2. Class II✓ Yes

    2,001–3,500 lbs

    Large folding camping trailers, single-axle, small- to medium-length (up to 18-ft.) trailers.

Real trailers

Can the HUMMER EV pull these?

Weights are what each trailer maker publishes (retrieved 2026-09-27). We compare the trailer's GVWR — the most it may weigh loaded — with each HUMMER EV configuration's rating, and never a dry weight when a GVWR exists.

Fine print, made plain

What the rating assumes

Every rating assumes a 150-lb driver and passenger and no other cargo. Add people, gear or accessories and the trailer you can tow goes down by the same amount.

The five weights, in one picture

Tongue weightLoaded trailer weightPayloadGVWR: the loaded truckGCWR: truck + trailer together
Loaded trailer weight — must stay under the towing rating
The rating “It assumes a towing vehicle with any mandatory options, no cargo, tongue load of 10% (conventional trailer) or king pin weight of 15% (5th-wheel trailer), and driver and passenger (150 lbs. each).” Weight of additional options, passengers, cargo and hitch must be deducted from this weight. p. 7 ↗
Tongue weight — the part of the trailer pressing on the hitch
“For trailers up to 2,000 lbs., tongue load not to exceed 200 lbs. For conventional trailers over 2,000 lbs., tongue load is 10% of loaded trailer weight. For 5th-wheel trailers, king pin weight is 15% of loaded trailer weight.” p. 7 ↗
Payload — people and cargo the truck can carry
“Payload is the combined maximum allowable weight of cargo and passengers that the vehicle is designed to carry. It is the Gross Vehicle Weight Rating minus the Base Curb Weight.” And: “When towing, trailer tongue load or king pin weight is also part of the Cargo Weight.” p. 6 ↗
GVWR and GCWR — the two ceilings
“Gross Vehicle Weight Rating (GVWR) is the maximum allowable weight of the fully-loaded vehicle (including passengers and cargo).” “Gross Vehicle Weight PLUS Loaded Trailer Weight EQUALS Gross Combination Weight (GCW) GCW must not exceed GCWR.” Your GVWR is on the label on the driver's door jamb. p. 6 ↗
