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.

As it’s a Porsche don’t expect it to be cheap in terms of tyres, insurance or maintenance – although at least it has long service intervals of 20,000 miles. It’s fairly economical for a sports car though and in terms of residual values will hold onto its price better than many rivals – due in no small part to the badge.

It’s no surprise that the Boxster isn’t particularly environmentally friendly. It averages 249g/km of CO2 but fuel economy is more acceptable – the standard model can average a decent 30mpg while the S will return around 27mpg.

Porsches are mainly hand built and standards of engineering are very high. Despite the sky high expectations of the average Porsche owner, very few are ever disappointed by the reliability of their car.
