MPG and running costs

One of the benefits of switching to a downsized turbocharged engine is an improvement in fuel efficiency. Porsche quotes a best economy figure of 38.2mpg on the combined cycle (Carrera with PDK), dropping to 32.5 for a manual Carrera S. These are useful 10-15 per cent improvements over the old normally aspirated Carreras.

Those are the official figures, anyway. Drive the 911 as it was designed to be driven and those figures will drop into the low-20s, with 30mpg within reach in mixed, everyday driving. Frustratingly, economy in normal usage isn't a great deal better than its naturally-aspirated predecessor, so it does feel a little like we've compromised the sound and response of those old units for a nonexistent improvement.

The 911 Turbo is rated at 31mpg while the GT3 RS is said to achieve 22.2mpg, but as ever those figures are optimistic at best. 

Servicing, meanwhile, can be expensive. The hi-tech 911 uses lots of high quality parts and consumables like tyres and brake pads, so don’t expect family hatch maintenance costs. And you’ll need to put aside at least £1000 per scheduled service. The good news is that, unlike most other manufacturers Porsche requires you to get your 911 serviced only every two years.

Group 50 insurance means big premiums but residuals are strong – a standard Carrera should retain more than 50 per cent of its value over three years.
