Where each one leads
BMW 3 Series
- Against cars of the same age, the BMW 3 Series comes out better at its first MOT test (passes 9% more often than average) than the Honda Accord (passes 4% more often than average).
- New BMW 3 Series cars registered in Europe in 2022 average 98 g/km of CO₂ on the WLTP test, against 173 for the Honda Accord in 2022.
Honda Accord
- Fewer Honda Accord cars in the Netherlands carry an illogical odometer record (5.0% against 5.4%).
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
