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 20 - 29 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.

The 911 is not a cheap car, but it does enjoy very strong residual values, so you'll get back much of what you initially spent if you decided to sell or trade in for a newer model. Insurance, servicing, fuel and tyres aren't cheap but Porsche has worked to reduce these by extending service intervals over the previous model and designing it to be cheaper to repair if there's minor damage.

By family car standards the 911 performs poorly on the environmental front with average emissions of 295g/km of CO2. However the company has worked to reduce this and facelifted Carrera and Carrera S models from 2008 have lower emissions. Considering the performance on offer fuel economy is more than acceptable - the 3.6-litre Carrera returns 29mpg.

Not bad for a car with 345bhp.

One of the biggest factors that keeps owners coming back to Porsche is the largely hand-built construction process for the 911 which creates a product that is exceptionally well engineered and reliable.
