Where each one leads
Ford Flex
Ahead on none of the like-for-like measures.
Kia Sorento
- On Canada's official test the most frugal 2026 Kia Sorento uses 9.4 l/100 km, the 2019 Ford Flex 12.7.
Too close to call: new York safety inspections failed, against cars of the same year.
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
