Quick verdict
The BMW iX1 has a higher peak charging speed at 128 kW DC, but the Opel Frontera Electric actually finishes the 10-80% charge faster (26 min vs 33 min) thanks to its smaller battery. The BMW iX1 is more efficient at 170 Wh/km. The BMW iX1 offers more WLTP rated range at 440 km.
Side-by-Side Specs
| Spec | BMW iX1 | Opel Frontera Electric |
|---|---|---|
| Battery (approx.) | ~64.7 kWh | ~44 kWh |
| WLTP range (rated) | ~440 km | ~305 km |
| Efficiency (approx.) | ~170 Wh/km | ~183 Wh/km |
| Max DC charging | up to 128 kW | up to 100 kW |
| 10-80% charge time (approx.) | ~33 min | ~26 min |
| Max AC charging | up to 11 kW | up to 7.4 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BMW iX1 has a peak DC charging speed of 128 kW, which is roughly 28% faster than the Opel Frontera Electric at 100 kW. In practice, peak speed only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.
For the 10-80% charge (the most common DC fast charging scenario), the Opel Frontera Electric finishes in about 26 minutes, which is 7 minutes quicker than the BMW iX1 at 33 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW iX1 has a WLTP rated range of approximately 440 km, which is roughly 135 km more than the Opel Frontera Electric at approximately 305 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.
Efficiency matters more than battery size for daily driving costs. The BMW iX1 consumes 170 Wh/km, compared to 183 Wh/km for the Opel Frontera Electric. That means the BMW iX1 uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.
A more efficient car does not always mean more range. Battery size plays a role too. The BMW iX1 has approximately 64.7 kWh of useable battery , while the Opel Frontera Electric has approximately 44 kWh.
Which One Should You Choose?
The BMW iX1 has the higher peak DC speed at up to 128 kW, but the Opel Frontera Electric actually finishes the 10-80% charge faster at approximately 26 minutes versus approximately 33 minutes. That is because the Opel Frontera Electric has a smaller battery to fill. On road trips, time at the plug matters more than peak power.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the BMW iX1 supports up to 11 kW, compared to 7.4 kW for the Opel Frontera Electric. In Europe, many public chargers are 22 kW AC, so this difference can mean charging roughly twice as fast at those locations.
If you mostly charge at home or at work and care more about daily driving costs, the BMW iX1 is the more efficient choice at 170 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW iX1 has a WLTP rated range of approximately 440 km, which is roughly 135 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
