Petrol against the other Fiat 500X fuels
Official DVSA test results by fuel, with 73 Auto's adjusted ratio (failures against cars of the same age, mileage and fuel). The petrol cars were tested 1.2 years younger on average than the diesel ones, so the raw pass rates partly reflect age; the adjusted column doesn't.

What this does and doesn't tell you
Fuel is DVSA's recorded fuel type; plug-in and self-charging hybrids are grouped as hybrid. A difference between fuels can come from the engines themselves, or from how the cars are used — diesels typically cover more miles, and the adjusted ratio allows for mileage band but not for every difference in use. For one car, its own MOT history is the better guide: see MOT check.

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.
