Polestar 5 vs Porsche Taycan

The Polestar 5 costs £1,300 more than the Porsche Taycan. For that premium it adds 54 miles more WLTP range, 80 kW faster peak rapid charging and 230 kW more power. The Porsche Taycan is not just cheaper - it also offers a 1.4s quicker 0-62mph time. On EVcarsguide's combined category scores, the Porsche Taycan comes out ahead overall.

The Porsche Taycan is £1,300 cheaper to buy. Running costs are almost identical - about £168 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Taycan comes out roughly £1,420 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 309 miles for the Polestar 5 and 306 miles for the Porsche Taycan - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. Both rapid-charge to 80% in a similar time, around 18-22 minutes.

The Porsche Taycan is the easier car for tight UK car parks: it is 49 mm narrower than the Polestar 5. In a standard 2,400 mm bay that leaves about 434 mm of total clearance for the Porsche Taycan and about 385 mm of total clearance for the Polestar 5. The Porsche Taycan also turns in a 0.6 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 Polestar 5 and 84% for the Porsche Taycan. 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.
