BMW i3 2014: MOT failure rate for its age
14.4% of 7,298 MOT tests of the BMW i3 first registered in 2014 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 100.5 (95% CI 94.4–106.5; 100 = normal for this model at that age): the 2014 build year is no different from other years of the same model at the same age.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 14.4 | % | all ages tested | 2019–2024 | 7298 |
| Index against this model at the same age (95% CI 94.4–106.5) | 100.5 | index | 100 = normal for this model at that age | 2019–2024 | 7298 |
| Rank among this model's 8 build years | 5 | of 8 | 1 = fails least for its age | 2019–2024 | 7298 |

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
