Winter Range
BMW iX Winter Range
Updated March 2026
The BMW iX has a standard heat pump and preconditioning, which help offset the range impact of its large SUV body in cold weather. With a 71 kWh battery and 405 km rated range, expect around 290-325 km in mild cold and 260-290 km in severe cold. Based on what our users tell us, the iX's winter range is manageable with good habits, but its tall profile means cold weather has a noticeable effect. In cold weather, expect roughly 310 km at -10°C, a loss of about 27%. These are estimates and your actual range will vary. Check your vehicle's manual for exact specifications.

Range by Temperature
These are estimates based on the BMW iX's battery size, efficiency, and whether it has a heat pump. Real results depend on driving style, terrain, speed, and cabin heating use.
| Temperature | Est. range | vs. summer |
|---|---|---|
| -20°C | 276 km | -35% |
| -15°C | 289 km | -32% |
| -10°C | 310 km | -27% |
| -5°C | 340 km | -20% |
| 0°C | 370 km | -13% |
| +5°C | 387 km | -9% |
| +10°C | 404 km | -5% |
| +15°C | 417 km | -2% |
| +20°C | 425 km | baseline |
Maximizing Winter Range
- Precondition the iX through the BMW app while plugged in. The iX has a spacious cabin that takes more energy to heat, so warming it on grid power saves meaningful battery range.
- The iX's standard heat pump handles cabin heating efficiently, but the large interior means it works harder than in a sedan. Use the zone climate feature to heat only occupied seats, and rely on heated seats for personal warmth.
- Set your winter charge limit to 90%. The iX's 71 kWh battery benefits from the extra buffer, giving you about 290 km even in mild cold.
- The iX's tall SUV shape increases aerodynamic drag, which is worse in cold, denser winter air. Reduce highway speed by 10-15 km/h in cold weather to offset this effect on range.
- Before DC fast charging in winter, let the iX precondition the battery via navigation routing. A warm battery charges faster and accepts more power, getting you back on the road sooner.
