Porsche 911 review - MPG, CO2 and running costs
Stringent emissions regulations continue to put the squeeze on Porsche’s engines, but that does yield improved efficiency
The Porsche 911 is no fuel economy hero, but in context of its rivals and its own capabilities, most are remarkably efficient. The 911’s engine upgrades might unlock more power but they also improve fuel consumption. Carrera models have MPG figures of up to 28mpg (233g/km) for a PDK Carrera S, reducing to 26.2mpg (244g/km) for a GTS Cabriolet at its worst.
Both 911 Turbos have the same 23.5mpg (271g/km) figure which you’ll agree is impressive considering the immense performance on tap, however use that performance and those numbers quickly drop much deeper towards single figures than you’ll manage in a Carrera.
Finally, the GT3s 21.9mpg and 21mpg for the RS make them the least efficient, but without a turbocharger these figures are more static under a variety of driving scenarios than you might expect.
Insurance groups
It’s no surprise that with this level of performance on offer, the desirability and the price, that the 911 falls into the top group 50 insurance bracket no matter which model you’re after. That means it’ll not be a cheap car to insure, but then neither are its rivals at this level of the market.
For our sample driver – a 43-year-old male living in Oxfordshire with three points on their licence – expect to pay around £1,000 a year. Of course, this could vary depending on your driving history, age, where you live and how many points you have.

Depreciation
Porsche 911 used values are traditionally very strong and the 992 is no different. The 'entry' Carrera model is predicted to hold onto around 69 per cent of its original list price after three-years and 36,000-miles of motoring, while the Carrera S and GTS versions are a little lower at 64 and 61 per cent respectively.
The GT3 model is the strongest used bet, as it's expected to retain around 73 per cent of its value over the same three-year period - although you will, of course, be paying out more to purchase the GT3 compared to a regular Carrera model. If you’re on good enough terms with your Porsche dealership, early access to one of the more desirable 911 variants will give you a car whose value is likely to go up before it goes down, especially with GT models.
The resale values of Turbos have become a lot more resilient over the last decade or so, maintaining a decent 65 per cent of their original value.
