Where each one leads
Audi SQ8
- Against cars of the same year, the Audi SQ8 comes out better in New York safety inspections (fails 57% less often than average) than the BMW X5 (fails 50% less often than average).
BMW X5
- Fewer BMW X5 cars in the Netherlands carry an illogical odometer record (3.4% against 4.9%).
- On Canada's official test the most frugal 2026 BMW X5 uses 9.4 l/100 km, the 2026 Audi SQ8 14.2.
- New BMW X5 cars registered in Europe in 2022 average 113 g/km of CO₂ on the WLTP test, against 288 for the Audi SQ8 in 2022.
Too close to call: real-world fuel use in Europe, petrol (l/100 km).
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
