Frequently asked questions
Is the Porsche Taycan worth the extra £6,827 over the Polestar 3?
The Porsche Taycan costs £6,827 more than the Polestar 3. For that premium it adds 145 kW more power and a 3.8s quicker 0-62mph time. The Polestar 3 is not just cheaper - it also offers 122 miles more WLTP range, 85 kW faster peak rapid charging and 77 litres more boot space. On EVcarsguide's combined category scores, the Polestar 3 comes out ahead overall.
Which is cheaper to own over 5 years, the Polestar 3 or the Porsche Taycan?
The Polestar 3 is £6,827 cheaper to buy. Running costs are almost identical - about £192 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 £6,947 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Polestar 3 and Porsche Taycan like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 257 miles for the Polestar 3 and 211 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 47 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-22 minutes.
Which is easier to park and drive in town, the Polestar 3 or the Porsche Taycan?
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.
Which battery will hold up better as a used buy, the Polestar 3 or the Porsche Taycan?
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.
