Where each one leads
BMW X1
Ahead on none of the like-for-like measures.
Nissan Ariya
- NHTSA rates the 2026 Nissan Ariya at 5 of 5 stars, the 2026 BMW X1 at 4.
- New Nissan Ariya cars registered in Europe in 2022 average 0 g/km of CO₂ on the WLTP test, against 117 for the BMW X1 in 2022.
Too close to call: dutch odometer readings judged illogical.
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
