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 Smart (Mcc) Forfour specifically, electric is the strongest at 84.8%, and this petrol version sits 0.1 points above the 79% 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 Smart (Mcc) Forfour had covered 45,301 miles at test, against 21,152 for the electric and 113,489 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 Smart (Mcc) Forfour page separate age from fuel if you want to isolate one.
