Bentley Bentayga 2020: MOT failure rate for its age
3.4% of 797 MOT tests of the Bentley Bentayga first registered in 2020 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 66.6 (95% CI 41.5–91.7; 100 = normal for this model at that age): the 2020 Bentley Bentayga fails less often than other build years of the same model at the same age. This is a rough estimate from a smaller sample.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 3.4 | % | all ages tested | 2019–2024 | 797 |
| Index against this model at the same age (95% CI 41.5–91.7) | 66.6 | index | 100 = normal for this model at that age | 2019–2024 | 797 |
| Rank among this model's 5 build years | 1 | of 5 | 1 = fails least for its age | 2019–2024 | 797 |
| Tested in 2024 | 393 | tests | median 23,906 miles | 2024 | 393 |

How does the 2020 Bentley Bentayga fail at each age?
Cars built in 2020 were tested at ages 3 to 4 between 2019 and 2024. Each row compares their first-time failure share with what this model normally shows at that age, after allowing for the overall failure level of each test year.
| Age | Tests | Failed, % | 95% interval | Normal for this model at that age, % | Index (100 = normal) |
|---|---|---|---|---|---|
| 3 | 404 (rough estimate) | 3.7 | 2.3–6 | 4.5 | 82 |
| 4 | 393 (rough estimate) | 3.1 | 1.8–5.3 | 5.7 | 53.9 |

How does 2020 compare with the years around it?
Among the 5 published build years of the Bentley Bentayga, 2020 ranks 1 (1 = fails least for its age). 2019: index 100.1.

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.
