BMW iX (2021-2025) vs MG IM6

The BMW iX costs £21,910 more than the MG IM6. For that premium it adds a 0.8s quicker 0-62mph time. The MG IM6 is not just cheaper - it also offers 131 miles more WLTP range, 246 kW faster peak rapid charging and 165 litres more boot space. On EVcarsguide's combined category scores, the MG IM6 comes out ahead overall.

The MG IM6 is £21,910 cheaper to buy. Running costs are almost identical - about £200 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the MG IM6 comes out roughly £21,910 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.

EVcarsguide estimates a real-world motorway range of about 214 miles for the BMW iX and 275 miles for the MG IM6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The MG IM6 goes roughly 60 miles further between charging stops. A rapid charge to 80% takes around 35 minutes in the BMW iX and 17 in the MG IM6, so the MG IM6 loses less time at each stop. That makes the MG IM6 the stronger long-distance car.

The two are within 18 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 430 mm of total clearance for the BMW iX and about 412 mm of total clearance for the MG IM6. The MG IM6 also turns in a 2.6 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the BMW iX and 84% for the MG IM6. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation. Both batteries carry a 8-year manufacturer warranty.
