Where each one leads
Kia Sorento
- On Canada's official test the most frugal 2026 Kia Sorento uses 9.4 l/100 km, the 2026 Toyota Grand Highlander 10.0.
Toyota Grand Highlander
- Against cars of the same year, the Toyota Grand Highlander comes out better in New York safety inspections (fails 9% less often than average) than the Kia Sorento (fails 26% more often than average).
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
