Versions and consumption
| Version | Usable battery | Consumption | Estimated range | Max charging (AC / DC) | |
|---|---|---|---|---|---|
| 286 ch · 2020 | 73.8 kWh | 18.6 kWh/100 km | ≈ 377 km | 11.0 / 150 kW | Calculate |
Reference version: 286 ch · 2020.
What it costs, version by version
| Version | 100 km at home, off-peak | 100 km at home, standard rate | 100 km at a rapid charger | 10 → 80 % at home, off-peak | 10 → 80 % at a rapid charger |
|---|---|---|---|---|---|
| 286 ch · 2020 | €3.31 | €4.17 | €9.57 | €9.19 | €26.58 |
Winter and summer: the effect on cost
For the reference version (286 ch · 2020), in an oceanic climate (western France) and mixed driving: 21.2 kWh/100 km in January, i.e. €3.78 per 100 km off-peak, against 18.8 kWh/100 km in July, i.e. €3.35. Charging therefore costs about 13 % more in January than in July.

At 18.6 kWh/100 km (reference version), the BMW iX3 ranks 122 out of 230 models in the Watt Budget database, from most to least frugal. The median is 18.4 kWh/100 km.
Assumptions
- Consumption: average used in the Watt Budget database for each version (sources: Open EV Data and spec sheets). It may differ from your use.
- Home prices: EDF Tarif Bleu on 1 August 2026, 6 kVA, incl. VAT: off-peak €0.1589 per kWh, standard rate €0.2001 per kWh.
- Rapid charger: €0.49 per kWh, indicative price (it varies by network and subscription).
- Charging losses: 12 % at home (Watt Budget’s automatic estimate for a 6.9 kW charger in mild weather), 5 % at a rapid charger. You pay for more kWh than end up in the battery.
- 10 → 80 % charge: 70 % of the usable battery. Estimated range: 95 % of the usable battery at average consumption.
- Winter and summer: model of the Seasons tab (average monthly temperature, consumption curve), mixed driving, no heat pump.
