Porsche Cayenne Estate running costs and reliability
Miles per pound (mpp)
Fuel economy
Porsche may have a reputation for high prices, but the Cayenne is now on par with other 4x4s like the BMW X5 in terms of list prices. It will hold its value very well too, shedding about half of it after three years but its not cheap to run. Porsche servicing is expensive as are consumables such as tyres and brakes. Even though a diesel is available, it still sits in the highest car tax band – like the rest of the model range.
Fuel consumption is pretty high and it will be expensive to insure and service.
The Cayenne’s powerful petrol engine line-up returns just 19mpg on average, so it’s no surprise that it scores so lowly on the eco front. With emissions of 346g/km CO2 – which is very high compared to an average family car – the Cayenne isn’t environmentally friendly. Thankfully there’s now a diesel which offers reasonable emissions of 244g/km of CO2 and averages 31mpg.
However, that’s still not as good as the faster BMW X5 XDrive 30d.
Porsche’s two-year warranty is 12 months short of most on the market, but we’ve heard of few problems with these cars and Porsche dealers will be keen to put right any faults discovered.
