Petrol against the other Mercedes-Benz A versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 90.4% | 62,295 |
| Diesel | 88.9% | 29,184 |
| All Mercedes-Benz A | 90% | 91,485 |
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 Mercedes-Benz A specifically, petrol is the strongest at 90.4%, and this petrol version sits 0.4 points above the 90% model average.
What it means if you are buying one
There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average petrol Mercedes-Benz A had covered 32,240 miles at test, against 41,940 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 Mercedes-Benz A page separate age from fuel if you want to isolate one.
