MPG and running costs
Although economy and emissions have taken steps in the right direction, if they remain significant factors in the purchasing mix, there are still important decisions to be made. The only no brainer here is the E-Hybrid which is by far the most economical and cleanest Cayenne with the ability to run up to 22 miles on electricity alone and official combined fuel economy stats of 83.1mpg and 79 g/km of CO2. The real world figures won’t be anything like as good but should still make the Cayenne comfortably the most frugal performance SUV you can buy.
Next best for economy and efficiency is the V6 diesel, which posts a very respectable 42.8mpg combined. Even the massively fast V8 Turbo isn’t too tragic at 24.6mpg, but it does chuck out 270g/km of CO2, and that’s 100g/km more than the Porsche Cayenne Diesel. Strong projected residual values of 57.2 per cent over three years are a plus for private buyers.
