Where each one leads
Kia Sportage
- On Canada's official test the most frugal 2026 Kia Sportage uses 8.3 l/100 km, the 2026 Mazda CX-5 9.0.
- New Kia Sportage cars registered in Europe in 2022 average 123 g/km of CO₂ on the WLTP test, against 165 for the Mazda CX-5 in 2022.
- Measured by the cars' own fuel meters, the petrol hybrid Kia Sportage uses 7.4 l/100 km on the road, the Mazda CX-5 8.0.

Mazda CX-5
- Against cars of the same age, the Mazda CX-5 comes out better at its first MOT test (passes 3% more often than average) than the Kia Sportage (passes 1% less often than average).
- Fewer Mazda CX-5 cars in the Netherlands carry an illogical odometer record (1.2% against 1.7%).
Too close to call: new York safety inspections failed, against cars of the same year; NHTSA overall safety rating.
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
