BMW iX vs Porsche Macan Electric

The BMW iX costs £9,805 more than the Porsche Macan Electric. For that premium it adds 28 miles more WLTP range, 135 kW more power and a 1.0s quicker 0-62mph time. The Porsche Macan Electric is not just cheaper - it also offers 75 kW faster peak rapid charging. On EVcarsguide's combined category scores, the Porsche Macan Electric comes out ahead overall.

The Porsche Macan Electric is £9,805 cheaper to buy. Running costs are almost identical - about £152 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Macan Electric comes out roughly £9,725 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 355 miles for the BMW iX and 332 miles for the Porsche Macan Electric - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The BMW iX goes roughly 24 miles further between charging stops. A rapid charge to 80% takes around 35 minutes in the BMW iX and 21 in the Porsche Macan Electric, so the Porsche Macan Electric loses less time at each stop. So the BMW iX stops less often while the Porsche Macan Electric stops for less time - pick on which you would rather do.

The Porsche Macan Electric is the easier car for tight UK car parks: it is 32 mm narrower than the BMW iX. In a standard 2,400 mm bay that leaves about 462 mm of total clearance for the Porsche Macan Electric and about 430 mm of total clearance for the BMW iX. The Porsche Macan Electric also turns in a 0.7 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 Porsche Macan Electric. 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.
