Registration years in the 9Y0
How cars are assigned to a generation
DVSA records don't say which generation a car is, so 73 Auto assigns each test by first-registration date against its catalogue's on-sale dates for the 9Y0 (Jan 2018 to now). Cars registered within three months either side of a changeover are left out, because run-out stock of the old model and early cars of the new one are registered in the same months. Some cars near the edges may still be of the neighbouring generation.

About this data. These are MOT test results, not a measure of mechanical reliability: a car's MOT outcome reflects its condition on the day, which depends on how it has been maintained and driven as well as how it was built. Figures cover class 4 vehicles (cars and light vans), normal tests only (retests excluded), outcomes pass, fail and pass after rectification at the station; vehicles at least 2.5 years old at test. Tests from 2023-01-01 to 2024-12-30. “Compared with similar cars” means compared with the national rate for cars of the same age, mileage band and fuel. Contains public sector information licensed under the Open Government Licence v3.0. Makes and models are matched to 73 Auto's vehicle catalogue; tests that can't be matched are left out rather than guessed. See how the MOT figures are produced.
