Source: Brumble analysis of DVSA's 2025 MOT test year data, published under the Open Government Licence v3.0, based on 1.55 million Mercedes-Benz tests.

What this means

Mercedes-Benz posts a 77.0% pass rate, comfortably above the national average, based on 1.55 million tests across the 2025 test year. That places it above most mainstream volume brands, though slightly behind BMW and Audi within the premium German tier specifically.

The C-Class and A-Class, Mercedes' most commonly tested models, both sit a little below the brand's overall average, at 74.14% and 73.33% respectively, still comfortably above the national average, but a reminder that even a premium badge doesn't mean every individual model outperforms the brand's headline figure.
