Petrol against the other MINI Cooper S 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 MINI Cooper S specifically, hybrid is the strongest at 89.3%, and this petrol version sits 0.2 points above the 88.5% 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 MINI Cooper S had covered 40,110 miles at test, against 66,731 for the diesel and 33,174 for the hybrid. 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 MINI Cooper S page separate age from fuel if you want to isolate one.
