BMW iX3 range, battery & charging
Despite looking like a regular BMW, the iX3 uses cutting-edge battery and charging technology
|Range||Wallbox charge time||Rapid charge time|
|286 miles||11hrs 45mins (0-100%, 7.4kW)||27mins (0-80%, 150kW)|
The BMW iX3 not only matches rivals for range and charging speed, but in many cases, beats them. With a range of up to 286 miles, it exceeds the Mercedes EQC and Audi e-tron's official numbers and is only outdone by the Jaguar I-Pace. However, in our experience the BMW is more efficient in the real world.
The iX3's a maximum charging speed of 150kW is faster than its main rivals, too, with only the Tesla Model Y's 250kW speeds topping the BMW. If you have the necessary three-phase electrics, the iX3 can also charge at home at up to 11kW, though most owners will be limited to a 7.4kW home charging speed.
BMW iX3 range
BMW claims a range of up to 286 miles for the iX3 – beating rivals like the above-mentioned EQC and e-tron, but falling just shy of the I-Pace. On a full charge, our test car showed a range of just 180 miles – but that was on a cold, wet, winter’s day; we reckon 220 to 230 miles is realistic in milder weather. If you make the most of the car’s regenerative brakes and spend a lot of time in town, it could be better still.
More importantly, however, is a car's efficiency – normally measured in miles per kilowatt hour (mi/kWh). In our experience, the iX3 trumps its rivals in this regard; on our cold, damp test route, we managed a fairly impressive 2.6 to 2.7mi/kWh – even with several full-throttle launches and quick motorway runs. For comparison, while a Mercedes EQC will officially do between 3.0 and 3.2 miles per kWh, a figure of between 2.0 and 2.2 is more easily attainable.
The iX3 is bang up to date in this area, supporting charging speeds up to 150kW. That means if you plug an iX3 into a suitably fast ultra-rapid charger, it can be topped up from 0-80% in just under 30 minutes.
At home, using an 11kW wallbox (which requires three-phase electricity) the iX3 can be fully charged in around eight hours. However, most owners will limited to a 7.4kW unit or on-street charging-point, which will need just under 12 hours to do the same job.
In This Review
- 1VerdictRefined, spacious and good to drive, the BMW iX3 makes sense as an electric family SUV – but some rivals feel more special
- 2Range, battery & charging - currently readingDespite looking like a regular BMW, the iX3 uses cutting-edge battery and charging technology
- 3Running costs & insuranceAn efficient drivetrain and the same ultra-low company-car tax rate as any electric car make the iX3 very cheap to run for a big SUV
- 4Performance, engine & driveDespite being down on power compared to its rivals, the BMW iX3 feels fast and quite good fun; the ride is a little firm, though
- 5Interior, dashboard & comfortThe inside of the BMW iX3 is logically laid-out and well built, but rival models' cabins feel more modern and more luxurious
- 6Boot space, seating & practicalityWhile the BMW iX3 is less practical than the petrol model, it’s still a spacious and versatile family SUV – with a decent range to boot
- 7Reliability & safety ratingBMW has only an average reputation for reliability, but with fewer moving parts than its petrol models, the iX3 should be a dependable family SUV
