Petrol Fiat 500x: MOT pass rate

Petrol against the other Fiat 500x versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 82.1% | 23,290 |
| Diesel | 74.3% | 10,766 |
| All Fiat 500x | 79.6% | 34,056 |
Why the fuel type changes the number
Petrol cars avoid the DPF and emissions failures that catch diesels, and usually fail on the same consumables as any other car.
On the Fiat 500x specifically, petrol is the strongest at 82.1%, and this petrol version sits 2.5 points above the 79.6% model average.
What it means if you are buying one
The petrol Fiat 500x is the stronger side of this model on MOT data. Still judge the individual car, but the fuel type is a mild point in its favour. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Fiat 500x had covered 47,799 miles at test, against 65,152 for the diesel. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.
Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Fiat 500x page separate age from fuel if you want to isolate one.
