Where each one leads
Audi TT Roadster
Ahead on none of the like-for-like measures.
MINI Cooper
- Fewer MINI Cooper cars in the Netherlands carry an illogical odometer record (2.5% against 4.3%).
- On Canada's official test the most frugal 2026 MINI Cooper uses 7.4 l/100 km, the 2023 Audi TT Roadster 9.4.
- New MINI Cooper cars registered in Europe in 2022 average 129 g/km of CO₂ on the WLTP test, against 167 for the Audi TT Roadster in 2022.
- Measured by the cars' own fuel meters, the petrol MINI Cooper uses 7.1 l/100 km on the road, the Audi TT Roadster 8.5.
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
