2024 GMC Hummer EV Towing Capacity & Range
How far can a 2024 GMC Hummer EV go while towing? Estimated range at every trailer weight, payload limits, and charging strategy — everything you need to plan a towing trip.
Note: Heavy weight limits payload; ultra-fast 350 kW charging.
How Much Does Towing Reduce Range?
Formula: EPA range × (1 − 0.003 × trailer_weight_per_100_lbs). Based on SAE J2807 research and real-world EV towing data. Actual range varies with speed (highway towing at 65 mph loses more), terrain, temperature, and aerodynamics of the trailer.
Towing Range by Trailer Weight
| Trailer Weight | Est. Range | Range Loss |
|---|---|---|
| 500 lbs | 324 mi | −2% |
| 1,000 lbs | 319 mi | −3% |
| 2,000 lbs | 309 mi | −6% |
| 3,000 lbs | 299 mi | −9% |
| 4,000 lbs | 290 mi | −12% |
| 5,000 lbs | 280 mi | −15% |
| 6,000 lbs | 270 mi | −18% |
| 7,000 lbs | 260 mi | −21% |
| 7,500 lbsMax | 255 mi | −22% |
Charging Strategy While Towing
Plan for 30–40% shorter legs
If your typical charging stop is every 150–200 miles, plan for 90–130 miles when towing. The 2024 GMC Hummer EV with a trailer is carrying more weight and producing more aerodynamic drag.
Charge to 80%, not 100%
EV charging slows significantly above 80%. For towing trips, stop at 80% and charge more frequently rather than waiting for a full charge — it's faster and easier on the battery.
Use 350 kW DC fast chargers when available
The 2024 GMC Hummer EV supports up to 350 kW charging. A 20–80% top-up takes roughly 26 minutes. Plan breaks around meal stops to make the time useful.
Keep speed at or below 65 mph
Aerodynamic drag increases with the square of speed. Towing at 75 mph vs 65 mph can reduce range by an additional 15–20%. If you're range-anxious on a towing trip, slowing down is the most effective strategy.
Watch gross vehicle weight (GVW)
The 1,300-lb payload includes passengers, cargo, and tongue weight of the trailer (typically 10–15% of trailer weight). Staying under GVW is both a legal and safety requirement.
