Where each one leads
Kia K5
Ahead on none of the like-for-like measures.
Toyota Corolla
- Against cars of the same year, the Toyota Corolla comes out better in New York safety inspections (fails 6% less often than average) than the Kia K5 (fails 50% more often than average).
- On Canada's official test the most frugal 2026 Toyota Corolla uses 6.7 l/100 km, the 2024 Kia K5 8.3.
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
