How we measure

Data. Every car MOT in Great Britain in 2025 (31,475,521 first tests on cars first used 2005 to 2022), from DVSA's anonymised MOT test data. Retests are left out.

Passed first time. A car passed if its first test that year ended in a pass. Cars that failed and were fixed within the hour count as fails, as DVSA counts them.

Same age and mileage. We group every car by the year it was first used and its mileage (under 30k, 30–60k, 60–90k, 90–120k, over 120k). The comparison figure is what those groups scored, weighted to match the Niro's mix of ages and mileages.

Model. Every car DVSA records as a Kia Niro: 22 recorded model names, from "NIRO" to trims such as "NIRO 2 EV".

The full method, including how each report-card dot and year group is decided.
