While the BMW iX3 may look expensive compared to petrol and diesel X3s, it actually undercuts its electric rivals quite significantly. It’s also worth bearing in mind that the iX3 only comes in well equipped M Sport and M Sport Pro specifications – there's no bare-bones entry-level version as such.

Once you’ve bought your iX3, you should be able to save a pretty penny compared with this car’s petrol or diesel siblings. It’s easy to only look at the car’s range figure when deciding whether or not to take the plunge, but efficiency is equally important. And in this case, the BMW beats almost all of its competitors – largely due to weighing less than them. And as this is a zero-emissions model, company-car drivers benefit from the lowest possible tax rating.

BMW iX3 insurance group

Both the M Sport and M Sport Pro version of the iX3 fall into insurance group 44, while the conventional X3 sits in groups 28 to 40 – so it’d be safe to assume the iX3 will be more expensive to insure than its petrol, diesel or hybrid equivalent. Pure-electric rivals the Jaguar I-Pace and Audi e-tron are in groups 49 and 50 respectively, so they'll be more expensive to cover than the BMW.


Every iX3 comes with a three-year/unlimited-mileage warranty – just like the petrol and diesel versions of the X3. The car’s high-voltage battery is covered separately with an eight-year guarantee.


Due to the reduced complexity of pure-electric powertrains and the fact that they have fewer moving parts than a petrol or diesel engine, servicing is both cheaper and less frequently required. BMW offers up-front and pay-monthly options to cover the cost of maintenance, so you can tailor a plan to suit your needs.

Road tax

As the BMW iX3 emits no CO2, it’s exempt from road tax (VED). Its zero-emission status also means it escapes the London Congestion Charge until 2025 and it should be safe from future clean-air zones, too.
