Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 24 - 41 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

The Cayenne has been subject to a 4% price rise but the base model is still cheaper than the BMW X6. It’s probably a better bet when you consider resale values: the previous model retained half of its value after three years and we don’t expect the new model to be any different. In terms of maintenance Porsche Cayenne running costs aren’t cheap and tyres and brakes will be expensive to replace.

If you want to keep your tax bill down go for the S E-Hybrid or diesel.

Porsche has gone to great lengths to make this car as efficient as possible, reducing CO2 emissions and fuel consumption by 20% on average. The inclusion of start/stop technology on the tiptronic models and the lighter weight have reduced Porsche Cayenne emissions and improved fuel economy. The E-Hybrid is by far the cheapest to run, with an official combined fuel economy of 83.1mpg and CO2 emissions of 79g/km.

It runs in electric mode, which reduces emissions and fuel consumption, at speeds of up to 78mph. The 4.8-litre Cayennes though, are still ridiculously expensive to run and they aren’t particularly wonderful for emissions either.

The previous Cayenne was pretty bulletproof and no reports of rafts of dissatisfied customers. We expect the strong Porsche Cayenne reliability record to continue with the second-generation car. Although, as a brand, Porsche doesn’t feature in the UK customer satisfaction surveys, it has performed well in satisfaction surveys in the US.
