Petrol against the other Toyota Yaris versions

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 Toyota Yaris specifically, hybrid is the strongest at 87.7%, and this petrol version sits 1.7 points below the 79% model average.

What it means if you are buying one

The petrol Toyota Yaris 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. 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 Toyota Yaris had covered 71,902 miles at test, against 45,303 for the hybrid and 112,321 for the diesel and 75,141 for the electric. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.

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 Toyota Yaris page separate age from fuel if you want to isolate one.
