  • E-Hybrids your best option if fuel economy bothers you
  • Servicing and maintenance won’t be cheap

How much is it going to cost to run?

If you’re buying a Cayenne Coupe with an eye on running costs, head straight for one of the plug-in hybrid E-Hybrid as that will officially do the most miles-per-gallon (mpg) thanks to an electric range of up to 48 miles. However, you’ll need to be driving almost everywhere in electric mode to get near the claimed figure, which means making sure it’s charged up.

At least economy for the regular E-Hybrid proved better than expected on test. On a long mainly motorway run at a sensible pace, we managed just over 32mpg despite starting with a flat battery. The Turbo E-Hybrid will be thirstier than the V6 models, but you probably don’t need us to tell you that.

Similarly, the regular non-hybrid V6 will drink less fuel than the V8 if you’ve got a heavy right foot. But if mostly cruising there shouldn’t be too much in it. Either way, anything over 20mpg is probably doing well. Driving hard, we were in the low teens. This is not a car for the eco-conscious, really, even with that hybrid tag;.

Servicing and warranty

Like all Porsches, the Cayenne Coupe gets a three-year unlimited mileage warranty that can be increased to up to 15 years or 125,000 miles of cover for an additional fee via an official Porsche extended warranty.

E-Hybrids make tempting company cars.

Service intervals are every two years or 20,000 miles, though Porsche also recommends an annual visit to your local official Porsche centre (OPC). Servicing won’t be cheap, as this is a premium vehicle. But Porsche does offer fixed-price servicing and service plans to help spread costs.

Consumables such as tyres and brakes will also be very pricey for the Cayenne, but they need to be high-quality to keep such a large, heavy and fast vehicle safely on the road.

Reliability

  • Porsche has a reasonable reputation
  • Looks and feels very well built
  • Cayenne has had some recall issues

Generally speaking, Porsche builds high-quality cars that are extensively develop to an extreme degree of attention to detail. They are far from having a faultless reputation, but should still prove more reliable that many rivals.

There have been a few official recalls for this generation of Cayenne, suggesting that things don’t always go 100% smoothly on the production line. None of this would cause us to hesitate from recommending one.
