Used Porsche Cayenne (2010-2017) – MPG and running costs
E-Hybrid system makes the Cayenne cheaper to run than you'd think. The Turbo is less impressive, but still manages decent running costs.
Although economy and emissions took significant steps in the right direction with the second-gen Cayenne, they're still an important consideration with a big, heavy SUV. 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 relatively affordable to run for the type of car it is.
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.
