The Porsche Taycan is £8,055 cheaper to buy. The Porsche Taycan is cheaper to charge, roughly £168 a year versus £200 for the Volvo EX90, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Taycan comes out roughly £8,215 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 306 miles for the Porsche Taycan and 312 miles for the Volvo EX90 - 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 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 436 mm of total clearance for the Volvo EX90 and about 434 mm of total clearance for the Porsche Taycan. The Porsche Taycan also turns in a 0.3 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 Porsche Taycan and 84% for the Volvo EX90. 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.
