Petrol against the other Smart (Mcc) Fortwo versions
| Fuel | Pass rate | Tests |
|---|---|---|

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) Fortwo specifically, electric is the strongest at 91%, and this petrol version sits 0.2 points below the 84.8% 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. Buying a damaged one? run it through the analyzer, 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) Fortwo had covered 38,535 miles at test, against 19,926 for the electric. 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) Fortwo page separate age from fuel if you want to isolate one.
