Smart (MCC)’s first-time fail rate across 3 models was 22.5%, better than the national 22.6%. The spread between models below is the interesting part.
| Model | Tests | Pass rate | Fail rate | Median miles |
|---|---|---|---|---|
| Fortwo | 40,311 | 78.2% | 21.8% | 50,585 |

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.
