2015 BMW I8 MOT pass rate: 90.4% (1,875 tests)
Is the 2015 I8 getting worse?
Pass rate of 2015-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 90.1% +9.5 vs same-age |
|
| 2024 | 90.4% +11.8 vs same-age |
|
| 2025 | 90.8% +13.8 vs same-age |
The raw rate normally falls as cars age. The “vs same-age” figure compares this cohort with all UK cars registered in the same year, so normal ageing is not mistaken for a bad model year.

What mileage is too high for a 2015 I8?
