Where each one leads
Audi Q3
- Against cars of the same year, the Audi Q3 comes out better in New York safety inspections (fails 48% less often than average) than the Volkswagen ID.4 (fails 6% less often than average).
Volkswagen ID.4
- Fewer Volkswagen ID.4 cars in the Netherlands carry an illogical odometer record (1.0% against 2.7%).
- New Volkswagen ID.4 cars registered in Europe in 2022 average 0 g/km of CO₂ on the WLTP test, against 123 for the Audi Q3 in 2022.
Too close to call: MOT pass rate against cars of the same age; 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
