2018 Volvo S90 MOT pass rate: 89.0% (7,378 tests)
Is the 2018 S90 getting worse?
Pass rate of 2018-registered cars across recent test years:
| Test year | Pass rate | |
|---|---|---|
| 2023 | 89.9% +1.8 vs same-age |
|
| 2024 | 88.5% +2.3 vs same-age |
|
| 2025 | 88.5% +3.7 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.
