Petrol against the other Porsche Cayenne 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 Porsche Cayenne specifically, hybrid is the strongest at 91.4%, and this petrol version sits 0.3 points below the 87.1% 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 Porsche Cayenne had covered 78,599 miles at test, against 89,592 for the diesel and 48,878 for the hybrid. 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 Porsche Cayenne page separate age from fuel if you want to isolate one.
