If you're looking for something similar in size, it might make sense to simply opt for the BMW iX1, which is based on the U11-generation X1, which replaced your current car in the BMW range in 2022. The range of the eDrive20 is up to 293 miles, however, it's some way short of your charging target, offering 130kW top-ups. If charging rate is especially important, also consider the Hyundai Ioniq 5, which manages up to 350kW. The Volvo XC40 Recharge splits the difference at 200kW. Whether or not you achieve any of these will depend on various environmental factors and whether you've used the car's pre-conditioning feature.
