Smart MOT pass rates
Smart’s first-time fail rate across 4 models was 20.2%, better than the national 22.6%. The spread between models below is the interesting part.

|---|---|---|---|---|
| Fortwo | 6,092 | 74.4% | 25.6% | 60,052 |
| Eq Fortwo | 1,641 | 94.6% | 5.4% | 11,135 |

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.
