Does high mileage mean more Smart Fortwo MOT failures at the same age?

At ages 10–14, 21.6% of Smart Fortwos with under 40,000 miles failed first time, against 44.6% of those with over 140,000 miles (2024, n = 5,384). Inside this age group, higher mileage goes with more failures.

Is the Smart Fortwo driven more or less than average, and does that change the picture?

This fleet is driven less than average. Matched on annual mileage as well as age (test chains 2019–2024), the index is 104.9, on the other side of normal, so both readings are shown.

Both readings are shown: this comparison changes when usage or inspection rules differ.

If a Smart Fortwo fails, does it fail again?

33.1% of Smart Fortwos that failed an MOT failed the next one too, against 23.3% after a pass (2019–2024, n = 19,629). The failure most likely to come back is road wheels: 43.9% of those fails recurred at the next MOT.

What does a Smart Fortwo cost to run in a fleet?

Of every 100 Smart Fortwos tested at age 5, about 13 failed the MOT first time (rough estimate); at age 10, about 23. These are one-year rates for different cars tested in the same year, not a fleet followed over time; the steepest one-year step in this cross-section is between cars aged 10 and 11, 5.94 percentage points (2024).

Does the Smart Fortwo fail inspections in other countries too?

In the Netherlands, 50.3% of Smart Fortwos failed their periodic roadworthiness inspection, against 50.8% for all cars there (2024 by country, n = 6,328 inspections).

Both readings are shown: this comparison changes when usage or inspection rules differ.

Inspections abroad disagree: Finland and the Netherlands point the same way as Britain, Norway do not. Test rules, climate and how the vehicles are used differ, so both readings are shown.

Smart Fortwo MOT: quick answers

What is the Smart Fortwo first-time MOT pass rate?

71.5% of first attempts passed in 2024 (51,770 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.

Why does this number differ from other sites?

Other sites may count retests or all attempts. This page uses 51,770 primary tests: 28.55% failed first time and 78.0% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 87.6 is shown separately.
