Diesel against the other Maserati Quattroporte versions
| Fuel | Pass rate | Tests |

| Diesel | 83.8% | 370 |
| All Maserati Quattroporte | 81.3% | 1,312 |
Why the fuel type changes the number
Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.
On the Maserati Quattroporte specifically, diesel is the strongest at 83.8%, and this diesel version sits 2.5 points above the 81.3% model average.
What it means if you are buying one
The diesel Maserati Quattroporte 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 diesel Maserati Quattroporte had covered 57,533 miles at test, against 60,879 for the petrol. That is around average, so condition and service history will tell you more than the odometer does.
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 Maserati Quattroporte page separate age from fuel if you want to isolate one.
