Bentley MOT pass rates
Bentley’s first-time fail rate across 3 models was 6.9%, better than the national 22.6%. The spread between models below is the interesting part.
| Model | Tests | Pass rate | Fail rate | Median miles |
|---|---|---|---|---|
| Continental | 13,521 | 92.9% | 7.1% | 41,015 |
| Bentayga | 2,912 | 96.1% | 3.9% | 34,448 |
| Arnage | 1,302 | 88% | 12% | 57,492 |
Fail rates are first attempts at class 4 normal tests in 2025, from DVSA’s anonymised data (retrieved 2026-09-12). Age mix drives a lot of the spread: a model sold mostly since 2020 will beat one whose survivors average 15 years old. Each model page shows the rate by age band.
