- Against cars of the same age, the Audi TT comes out better at its first MOT test (passes 13% more often than average) than the Volvo C30 (passes 3% less often than average).
- Against cars of the same year, the Audi TT comes out better in New York safety inspections (fails 24% less often than average) than the Volvo C30 (fails 16% more often than average).

Volvo C30
- Fewer Volvo C30 cars in the Netherlands carry an illogical odometer record (2.8% against 10.0%).
- New Volvo C30 cars registered in Europe in 2022 average 156 g/km of CO₂ on the WLTP test, against 161 for the Audi TT in 2022.
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
