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 |
|---|---|---|---|---|---|
| 300 4MATIC · 2023 | €3.43 | €4.33 | €9.93 | €8.28 | €23.95 |
| 350 4MATIC · 2023 | €3.43 | €4.33 | €9.93 | €8.28 | €23.95 |
| 250 · 2022 | €3.26 | €4.10 | €9.42 | €8.28 | €23.95 |

Winter and summer: the effect on cost
For the reference version (350 4MATIC · 2023), in an oceanic climate (western France) and mixed driving: 22.0 kWh/100 km in January, i.e. €3.92 per 100 km off-peak, against 19.5 kWh/100 km in July, i.e. €3.47. Charging therefore costs about 13 % more in January than in July.
Compared with other models
At 19.3 kWh/100 km (reference version), the Mercedes EQB ranks 140 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.
