GMC Hummer EV (SUV/Pickup) in Cold Weather
Strong absolute winter range thanks to a massive pack, offset by the vehicle's extreme weight and consumption — a genuinely capable winter vehicle if you can accept the efficiency trade-off.
Specifications
| Specification | Value | Source |
|---|---|---|
| EPA range (20°C) | 381 mi (613 km) | EPA fueleconomy.gov — pickup 3X Extended Range (SUV 3X rated 314 mi) |
| Cabin heating | heat pump | Heat pump standard. |
| Battery | ~170–212 kWh Ultium pack depending on configuration — among the largest EV packs sold in the US. | GMC |
| Peak DC fast charge | 300 kW (NACS) | GMC |
| Recommended preconditioning | 20–30 min while plugged in via app/schedule | GMC |
| Cold-charging behavior | An enormous pack buffers winter range loss well and supports fast charging, but extreme curb weight (9,000+ lb) means proportionally more energy goes to moving the vehicle itself, and winter tires matter enormously for control. | Manufacturer + third-party tests |
Cold-weather tips
- 1
Prioritize winter tires
At 9,000+ lb, stock tires are badly overmatched in snow — this matters more than on almost any other EV on this list.
- 2
Don't expect efficient miles-per-kWh
The huge pack means long range despite low efficiency — budget charging stops around energy use, not just percentage loss.
- 3
Schedule departure while plugged in
Warms the cabin and this very large pack from wall power before you drive.
- 4
Use built-in navigation to DC chargers
Triggers automatic preconditioning ahead of arrival.
