Where each one leads
Fiat 500
Ahead on none of the like-for-like measures.
MINI Cooper Convertible
- Against cars of the same year, the MINI Cooper Convertible comes out better in New York safety inspections (fails 32% less often than average) than the Fiat 500 (fails 15% less often than average).
- On Canada's official test the most frugal 2026 MINI Cooper Convertible uses 7.7 l/100 km, the 2019 Fiat 500 7.9.
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
