Polestar 3 (2024-2025) vs Porsche Taycan

The Porsche Taycan costs £18,300 more than the Polestar 3. For that premium it adds 100 kW more power. The Polestar 3 is not just cheaper - it also offers 71 miles more WLTP range, 77 litres more boot space and 1 more seat (5 versus 4). On EVcarsguide's combined category scores, the Polestar 3 comes out ahead overall.

The Polestar 3 is £18,300 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 Polestar 3 comes out roughly £18,260 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 365 miles for the Polestar 3 and 306 miles for the Porsche Taycan - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Polestar 3 goes roughly 60 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-22 minutes.

The two are within 2 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 434 mm of total clearance for the Porsche Taycan and about 432 mm of total clearance for the Polestar 3.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Polestar 3 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.
