Diesel against the other Alfa Romeo GT versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 56.9% | 866 |
| Petrol | 66.9% | 717 |
| All Alfa Romeo GT | 61.4% | 1,584 |
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 Alfa Romeo GT specifically, petrol is the strongest at 66.9%, and this diesel version sits 4.5 points below the 61.4% model average.
What it means if you are buying one
The diesel Alfa Romeo GT fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Alfa Romeo GT had covered 113,868 miles at test, against 87,851 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.
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 Alfa Romeo GT page separate age from fuel if you want to isolate one.
