Where each one leads
Jeep Grand Cherokee
Ahead on none of the like-for-like measures.
Porsche Cayenne Diesel
- On Canada's official test the most frugal 2016 Porsche Cayenne Diesel uses 9.8 l/100 km, the 2022 Jeep Grand Cherokee 11.3.
- New Porsche Cayenne Diesel cars registered in Europe in 2022 average 189 g/km of CO₂ on the WLTP test, against 271 for the Jeep Grand Cherokee 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
