Petrol against the other Mercedes-Benz Cla versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Petrol | 85.2% | 34,177 |
| Diesel | 80.4% | 23,165 |
| All Mercedes-Benz Cla | 83.3% | 57,347 |
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 Cla specifically, petrol is the strongest at 85.2%, and this petrol version sits 1.9 points above the 83.3% model average.
What it means if you are buying one
The petrol Mercedes-Benz Cla 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. 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 Cla had covered 47,475 miles at test, against 77,920 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 Cla page separate age from fuel if you want to isolate one.
