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 25 - 31 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.

With a £45,000 asking price the Cayman S isn’t cheap (the standard Cayman is £8,000 cheaper), but it will depreciate very slowly. It should achieve about 25mpg in everyday driving (closer to 30mpg in the standard Cayman), and insurance costs will be high as the lowest insurance group is 42 stepping up to 45 for the S Design and S Sports. Service intervals are quite long, but the Cayman only comes with a two-year warranty.

The Cayman performs fairly poorly on the eco front by family car standards, but considering the performance it offers, average emissions of 220g/km of CO2 are actually quite good. Both models return around 30mpg.

Porsche has a very good reputation for reliability and no problems have been reported from owners so far. The two-year warranty isn’t as long as most manufacturers (many of which offer three years) but Porsche dealers take care of customers very well.
