Where each one leads
Porsche Cayenne
- Against cars of the same age, the Porsche Cayenne comes out better at its first MOT test (passes 16% more often than average) than the Volvo XC90 (passes 2% more often than average).
- Against cars of the same year, the Porsche Cayenne comes out better in New York safety inspections (fails 55% less often than average) than the Volvo XC90 (fails 32% less often than average).
- Fewer Porsche Cayenne cars in the Netherlands carry an illogical odometer record (2.8% against 5.2%).
Volvo XC90
- On Canada's official test the most frugal 2026 Volvo XC90 uses 10.4 l/100 km, the 2026 Porsche Cayenne 12.2.
- New Volvo XC90 cars registered in Europe in 2022 average 102 g/km of CO₂ on the WLTP test, against 250 for the Porsche Cayenne in 2022.
Only measures that do not depend on how many cars were sold: pass and failure rates against cars of the same age, ratings, fuel use and CO₂. How we compare
