Porsche Cayenne vs Volvo EX90 (2024-2025)

The Volvo EX90 costs £13,055 more than the Porsche Cayenne. For that premium it adds 2 more seats (7 versus 5). The Porsche Cayenne is not just cheaper - it also offers 140 kW faster peak rapid charging and 457 litres more boot space. On EVcarsguide's combined category scores, the Porsche Cayenne comes out ahead overall.

The Porsche Cayenne is £13,055 cheaper to buy. The Volvo EX90 is cheaper to charge, roughly £200 a year versus £240 for the Porsche Cayenne, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Porsche Cayenne comes out roughly £12,855 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 234 miles for the Porsche Cayenne and 312 miles for the Volvo EX90 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Volvo EX90 goes roughly 78 miles further between charging stops.

The two are within 16 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 420 mm of total clearance for the Porsche Cayenne. The Volvo EX90 also turns in a 0.7 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 Cayenne 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.
