Where each one leads
Audi RS Q3
Ahead on none of the like-for-like measures.
BMW X4
- New BMW X4 cars registered in Europe in 2022 average 170 g/km of CO₂ on the WLTP test, against 227 for the Audi RS Q3 in 2022.
- Measured by the cars' own fuel meters, the petrol BMW X4 uses 10.8 l/100 km on the road, the Audi RS Q3 11.5.
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
