BMW i5 vs Porsche Macan Electric

The BMW i5 is £805 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the BMW i5 comes out roughly £845 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 297 miles for the BMW i5 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 Porsche Macan Electric goes roughly 35 miles further between charging stops. A rapid charge to 80% takes around 30 minutes in the BMW i5 and 21 in the Porsche Macan Electric, so the Porsche Macan Electric loses less time at each stop. That makes the Porsche Macan Electric the stronger long-distance car.

The BMW i5 is the easier car for tight UK car parks: it is 38 mm narrower than the Porsche Macan Electric. In a standard 2,400 mm bay that leaves about 500 mm of total clearance for the BMW i5 and about 462 mm of total clearance for the Porsche Macan Electric.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the BMW i5 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.
