MPG, running costs & CO2 Rating

3.0 out of 5

Fuelling and maintaining a sports car like the Porsche 911 is never going to be a cheap proposition, but some versions are remarkably economical when compared to direct rivals. Overall, running costs could still be eye-watering, though – expect to spend big money on insurance and routine maintenance.

Porsche 911 MPG & CO2

The most fuel-efficient 911 is the entry-level Carrera, which is capable of returning 38.2mpg when fitted with the optional PDK twin-clutch automatic gearbox. However, its CO2 emissions of 169g/km won’t put it at the top of anybody’s company-car list.

The more powerful Carrera S model is capable of 32.5mpg and CO2 emissions of 199g/km, which improve to 36.7mpg and 174g/km of CO2 with the PDK automatic gearbox. Choosing the Carrera 4 version (where the ‘4’ stands for four-wheel drive) sees economy slip slightly to 32.5mpg and CO2 emissions rise to 201g/km. The PDK gearbox improves these figures to 36.7mpg with CO2 emissions of 177g/km.

The quickest version of the Carrera, the GTS, is capable of 30.1mpg and CO2 emissions of 212g/km with the standard manual gearbox, or 34mpg and 188g/km with the PDK gearbox. The four-wheel-drive Carrera 4 GTS is slightly less economical at 29.7mpg with CO2 emissions of 216g/km for manual cars. Go for the optional PDK and official economy climbs to 33.2mpg with CO2 emissions of 192g/km.

Even the very quick Porsche 911 Turbo returns up to 31mpg and CO2 emissions of 212g/km, helped by a standard PDK gearbox. Although all models will be subject to considerable emissions-related initial registration fees, the next five annual road tax charges will each be £450, whereafter it reverts to £140 per year.

Insurance group

Although the group 47 insurance rating of entry-level Carrera models is fractionally lower than that of more powerful variants, every 911 will be costly to insure. Unfortunately, cars as sporty as the 911 are seen as high-risk by insurers. It’s always wise to seek an insurance quote to ensure that cover is possible before you make a buying decision.

Servicing

Prepare yourself for routine maintenance costs of around £1,000 per scheduled service, which are likely to rise if you drive the car hard often or use it for track days. There’s some relief in the fact that, unlike most other manufacturers, Porsche only recommends you service your 911 every two years.

Warranty

Every new Porsche comes with a three-year/unlimited-mileage warranty, which matches rivals such as Mercedes, Aston Martin and Jaguar.
