Where each one leads
Jeep Grand Cherokee
- Against cars of the same year, the Jeep Grand Cherokee comes out better in New York safety inspections (fails 18% less often than average) than the Mazda CX-9 (fails 1% more often than average).
- Fewer Jeep Grand Cherokee cars in the Netherlands carry an illogical odometer record (9.4% against 17.3%).
Mazda CX-9
- On Canada's official test the most frugal 2023 Mazda CX-9 uses 10.5 l/100 km, the 2022 Jeep Grand Cherokee 11.3.
- New Mazda CX-9 cars registered in Europe in 2022 average 207 g/km of CO₂ on the WLTP test, against 271 for the Jeep Grand Cherokee in 2022.
Too close to call: 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
