Where each one leads
BMW X3
- On Canada's official test the most frugal 2026 BMW X3 uses 8.1 l/100 km, the 2026 Porsche Macan 11.0.
- New BMW X3 cars registered in Europe in 2022 average 125 g/km of CO₂ on the WLTP test, against 224 for the Porsche Macan in 2022.
- Measured by the cars' own fuel meters, the petrol BMW X3 uses 10.8 l/100 km on the road, the Porsche Macan 11.2.
Porsche Macan
- Against cars of the same age, the Porsche Macan comes out better at its first MOT test (passes 12% more often than average) than the BMW X3 (passes 6% more often than average).
- Against cars of the same year, the Porsche Macan comes out better in New York safety inspections (fails 66% less often than average) than the BMW X3 (fails 32% less often than average).
- Fewer Porsche Macan cars in the Netherlands carry an illogical odometer record (1.3% against 2.2%).
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
