Where each one leads
Audi Q8
- Against cars of the same age, the Audi Q8 comes out better at its first MOT test (passes 5% more often than average) than the Hyundai Santa Fe (passes 4% less often than average).
- Against cars of the same year, the Audi Q8 comes out better in New York safety inspections (fails 40% less often than average) than the Hyundai Santa Fe (fails 1% more often than average).
- Fewer Audi Q8 cars in the Netherlands carry an illogical odometer record (1.0% against 2.5%).
Hyundai Santa Fe
- On Canada's official test the most frugal 2026 Hyundai Santa Fe uses 10.7 l/100 km, the 2026 Audi Q8 12.1.
- New Hyundai Santa Fe cars registered in Europe in 2022 average 101 g/km of CO₂ on the WLTP test, against 198 for the Audi Q8 in 2022.
- Measured by the cars' own fuel meters, the petrol hybrid Hyundai Santa Fe uses 7.9 l/100 km on the road, the Audi Q8 12.4.
- Measured by the cars' own fuel meters, the diesel Hyundai Santa Fe uses 7.5 l/100 km on the road, the Audi Q8 9.7.
Too close to call: 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
