Searches for a “2024 GMC Hummer EV range test” usually come from the same place: you’ve seen the wild specs, heard the nearly 400‑mile claims, and you’re trying to figure out what this 9,000‑plus‑pound super truck actually does on the road. Let’s walk through the official numbers, independent tests, and what you should expect day‑to‑day, especially if you’re thinking about buying a Hummer EV new or used.
Heavyweight, big battery, big expectations
Why the 2024 Hummer EV’s range is so talked about
Most EV coverage focuses on efficiency, how far you go per kilowatt‑hour. The GMC Hummer EV flips that script. It’s closer to a battery‑electric heavy‑duty truck than a typical light‑duty pickup, which is why early versions didn’t even need EPA range labels. Instead of sipping energy like a compact crossover, the Hummer EV uses a massive battery to brute‑force long range out of a nearly five‑ton off‑road rig.
For 2024, GMC expanded the lineup with dual‑motor and triple‑motor trims and two battery sizes. Official estimates now stretch into the high‑300‑mile range for some pickups, while EPA‑rated figures for lighter versions cluster around 300–314 miles. That gap between headline numbers and what you’ll see on a highway road trip is exactly what real‑world range tests help unpack.
Hummer EV battery and official range figures
2024 Hummer EV battery and range at a glance
Two pack sizes, multiple trims, and very different use cases
Battery packs
GMC uses its Ultium platform with two main configurations:
- 20‑module pack: roughly 170 kWh usable, standard on many EV2/EV2X/EV3X pickups and the SUV.
- 24‑module pack: roughly 205–213 kWh usable, optional on some 3X pickups and early Edition 1 trucks.
Official & GM‑estimated range
- 20‑module trucks & SUVs: EPA‑combined around 298–314 miles depending on tires and trim.
- 24‑module 3X pickups: GM‑estimated up to 381 miles on 22‑inch road tires, or about 359 miles with off‑road MT tires.
- Edition 1 pickup: originally estimated at 329 miles on a full charge.
The key takeaway is that the longest‑range 2024 Hummer EV pickups rely on the biggest available pack, relatively street‑friendly tires, and highway‑biased suspension tuning. As soon as you add the Extreme Off‑Road package or 35‑inch mud‑terrain rubber, you trade away some of those big range numbers for capability.

Real-world highway range tests: 2024 Hummer EV
Independent 70–75 mph highway tests are the best apples‑to‑apples comparison we have across EVs. For the Hummer EV, they paint a clearer picture than any marketing brochure.
Hummer EV highway range results (approximate)
Representative independent tests at a steady 70–75 mph, mild weather, starting from 100% charge on relatively flat routes.
| Model & trim | Battery configuration | Wheels / tires | Highway speed test | Observed range (mi) |
|---|---|---|---|---|
| Pickup Edition 1 (early build) | 24‑module Ultium (~212 kWh) | 35" off‑road MT | 75 mph loop | ~290 miles on a full charge |
| Pickup EV3X 20‑module | 20‑module Ultium (~170 kWh) | MT or AT off‑road | 75 mph loop | ~250–270 miles, depending on wind & temps |
| SUV EV3X 20‑module | 20‑module Ultium (~170 kWh) | All‑terrain 22" | 75 mph loop | ~240–255 miles in testing |
Use these numbers as directional guides; your terrain, weather, and tires will change the outcome.
Those results are roughly 10–20% below the best‑case combined ratings, which is right in line with what we see across most EVs: steady highway speed is harder on range than the mixed city/highway cycles used for EPA testing.
How to ballpark your Hummer EV road-trip range
Hummer EV SUV vs pickup: who goes farther?
Hummer EV Pickup
- Available with both 20‑ and 24‑module Ultium packs.
- Long‑range 3X with 24 modules and street‑oriented tires is where the 381‑mile GM estimate comes from.
- Off‑road packages with chunky tires typically drop estimates by 20–25 miles or more.
- Highway tests on Edition 1 trucks have returned around 290 miles at 75 mph when new.
Hummer EV SUV
- Shorter overall, with a 20‑module (~170 kWh) pack only.
- EPA‑combined ratings around 298–314 miles depending on wheels and tires.
- Independent 75‑mph tests have seen ~250 miles on a full charge, or about 80% of the label.
- Slightly lighter than the pickup but also slightly less aerodynamic, so real‑world range is broadly similar to 20‑module trucks.
If you’re cross‑shopping a used Hummer EV SUV against a used pickup, don’t expect dramatically different day‑to‑day range. The real divider is battery size and tire choice, not body style. A 24‑module road‑tire pickup will clearly out‑range a 20‑module off‑road SUV, but two similarly equipped trucks and SUVs will feel very close in the real world.
Towing with a Hummer EV: how hard does range fall?
If you’re eyeing a Hummer EV for camping or toy‑hauling, this is where range tests matter most. Towing exposes just how energy‑intensive it is to push a bluff, heavy brick through the air while dragging another one behind it.
What tests show when towing with a Hummer EV
A Hummer EV that can comfortably cover ~280–300 miles on the highway solo may only manage around 130–150 miles while towing a big camper. That’s the difference between stopping every 3–4 hours and stopping every 90 minutes, which dramatically changes how you plan road trips.
EV towing requires serious planning
Winter and off-road driving: how much range you lose
Cold temperatures and soft surfaces hit every EV’s range, but the Hummer EV’s mass and off‑road focus make those hits noticeable. Owners who’ve shared detailed logs out of their trucks see patterns that line up with physics: more rolling resistance, thicker gear oil, and a cold‑soaked 200‑plus‑kWh pack all add up.
- In mild cold (around freezing) on all‑terrain tires, expect 10–20% less range than in ideal 70°F weather at the same speeds.
- In deep cold (0°F and below) without preconditioning, drops of 25–35% aren’t uncommon, especially on short trips where the battery never fully warms up.
- Off‑roading at low speed can be surprisingly range‑friendly when you’re creeping along, but sand, mud, and rock crawling can spike energy use dramatically.
- Aggressive mud‑terrain tires can cost you another 5–10% compared with street‑oriented rubber, even in perfect weather.
Use preconditioning and drive modes wisely
Efficiency: why the Hummer EV guzzles electrons
On paper, the Hummer EV’s range can look similar to a Rivian R1T or Ford F‑150 Lightning. The difference is how much battery it takes to get there. Where a Lightning maxes out around 131 kWh, the Hummer EV can use roughly 170 kWh in 20‑module form and north of 200 kWh in 24‑module guise.
Approximate efficiency comparison
Rough efficiency figures to show how much energy the Hummer EV uses versus typical large EV trucks.
| Vehicle | Pack size (usable, approx.) | Typical highway efficiency | Miles per kWh (highway) |
|---|---|---|---|
| GMC Hummer EV Pickup (Edition 1) | ~212 kWh | ~40–42 kWh/100 km | ~1.5–1.6 mi/kWh |
| GMC Hummer EV SUV (20‑module) | ~170 kWh | ~44–48 kWh/100 km in testing | ~1.3–1.4 mi/kWh |
| Ford F‑150 Lightning ER | ~131 kWh | ~32–35 kWh/100 km | ~1.9–2.1 mi/kWh |
| Rivian R1T Large pack | ~135 kWh | ~30–33 kWh/100 km | ~2.0–2.2 mi/kWh |
These figures are illustrative; exact numbers vary by trim, tires, and test protocol.
When you think of the Hummer EV as an electron‑guzzling heavy‑duty rig rather than a frugal commuter, its numbers make more sense. The upside is brute capability and that towering driving position; the downside is that every mile costs more in energy and time at a DC fast charger.

Range-planning tips for Hummer EV owners
Six practical ways to make Hummer EV range feel predictable
1. Start trips at 90–100% when you can
Because the pack is huge, topping to 100% before a long drive gives you a big buffer. Do this for road trips, not every night, to keep charging stress reasonable.
2. Plan around 75–80% of official range
For interstate travel, build your plan around roughly three‑quarters of the official or GM‑estimated figure, then adjust with your own trip data over time.
3. Use your trip computer religiously
Watch your recent mi/kWh and the “projected” range in the instrument cluster. It will quickly show the impact of speed, headwinds, and terrain on this very heavy truck.
4. Respect the towing penalty
If you’re hauling a tall camper or car trailer, assume about half your solo range. Shorten your hop lengths, and favor chargers with easy trailer access.
5. Be realistic about winter
In cold climates, precondition when plugged in, use seat/steering wheel heaters instead of blasting HVAC, and keep your state‑of‑charge buffer larger than usual.
6. Choose tires with your usage in mind
If you spend most of your time on pavement, consider less‑aggressive tires when it’s time to replace the factory set. You can claw back a noticeable chunk of highway range.
Buying a used Hummer EV: what to watch for on range
On the used market, the 2022–2024 Hummer EVs you’ll see are almost all early Edition 1 and 3X pickups, plus a growing number of SUVs. Because the pack is so large, even modest degradation usually doesn’t make the truck unusable, but it does matter when you’re spending six figures on something this specialized.
Used Hummer EV range checklist
Questions to answer before you commit
Which pack and tires?
Confirm whether the truck has the 20‑ or 24‑module battery and what wheels/tires it’s running. A 24‑module street‑tire 3X will feel very different from a 20‑module Extreme Off‑Road truck on MTs.
Real trip data
Ask the seller for recent highway trip screenshots: state of charge, distance driven, and remaining range at typical speeds. That tells you far more than a static guess‑o‑meter number.
Independent battery health check
Whenever possible, get a third‑party battery health report so you’re not guessing about usable capacity. At Recharged, every vehicle includes a Recharged Score with verified battery diagnostics and pricing tied to real pack condition.

Frequently asked questions about Hummer EV range
Bottom line: is the 2024 Hummer EV’s range enough?
If your benchmark is efficiency, the 2024 GMC Hummer EV fails the range test spectacularly. It uses more energy per mile than almost any other EV on sale. But if your benchmark is sheer capability, off‑road toys, instant torque, and highway‑crushing battery capacity, the story looks different. In real‑world use, most trims can comfortably cover 240–290 highway miles solo, with far shorter legs while towing or in harsh winter conditions.
The important thing is to align the truck with your use case. If you want a weekend adventure rig and understand the trade‑offs, the Hummer EV’s range can be entirely workable. If you’re looking for a rational daily commuter, there are smarter choices. And if you decide a Hummer EV, or another big‑battery used EV, is right for you, shopping through Recharged gives you verified battery health, clear range expectations, and expert support so you’re never guessing about what your next charge will really deliver.
