  • Most economical is the E-Hybrid
  • Cayenne Turbo is thirsty
  • Strong predicted resale values

Thanks to the all-petrol engine line-up, those looking for a frugal Cayenne will be at a loss, for now.

The standard Cayenne’s V6 is good for a claimed 31.3mpg, the Cayenne S isn’t that far behind at 30.7mpg, while the V8 whopper in the Turbo can only manage 24.1mpg.

The star of the range is the E-Hybrid, claiming an impressive 83.1mpg. This will only be achievable if you really utilise the battery power around town, and are able to charge it as much as possible. If you don’t, you’re more likely to see a figure in the 30s, which still isn’t too bad considering it’s the second-fastest model in the line-up. 

Insurance and servicing costs will be high, but no more so that other cars in this sector. Fixed-price service packages are available.

It’s likely resale values will be fairly strong relative to rivals, but we’ve yet to receive this information at time of writing.

Actual fuel costs will vary based on driving style and road conditions.

How much is it to insure?

Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.

Green credentials

2.5 out of 5 2.5

Overall, CO2 output isn’t exactly something to write home about for the Cayenne.

The plug-in Cayenne E-Hybrid is the best performer here, with CO2 emissions of between 71-78g/km (variable depending on the size of the alloy wheels), meaning this car will appeal to company car drivers lucky enough to have this car on their list.

The best performance from the rest of the petrol range is the standard Cayenne, which can emit 205g/km if you specify it with small enough alloy wheels.

At the other end of the spectrum is the Turbo, which emits up to 272g/km of CO2 with the largest 21-inch wheels.

In fairness, though, these figures are favourable compared with rivals such as the Maserati Levante, once you’ve factored in performance figures too. 

Highest and lowest CO2 emissions

Engine CO2 emissions Road tax (12 months)
Petrol/PlugIn Elec Hybrid 72 g/km (Min) £455
3.0 Petrol 267 g/km (Max) £465

Porsche Cayenne SUV: will it be reliable?

Since this generation of Cayenne is fresh out of the box, it’s a little too early to make a judgement on just how reliable it will be.

Worth noting that its predecessor suffered from four recalls according to the DVSA vehicle inspectorate.

However, a lot of attention to detail goes into Porsche production, and the car feels very solid indeed, so there shouldn’t be too much to be concerned about.
