Porsche 911 review - MPG, CO2 and running costs

The 911’s new injectors give more power but also improve fuel consumption. With the help of a particulate filter in the exhaust, it’ll emit as little as 205g/km and return up to 28.5mpg. Impressive stats considering the performance on offer.

Given the sphere the 911 occupies, it’s one of the more efficient sports cars on sale and should therefore be relatively affordable to run. The caveat, of course, being that it’s affordable for a circa £100,000 sports car that can crack 0-62mph in under four seconds.

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 whether you go for the two or four-wheel drive option.

For our sample driver – a 43-year-old male living in Oxfordshire with three points on their licence – expect to pay around £1,000. Of course, this could vary depending on your driving history, age, where you live and how many points you have.

• The cars that hold their value best

Depreciation 

Porsche 911 used values are traditionally very strong. This car is so new that residual values are difficult to accurately predict, but based on the car it replaces – the 991.2 Carrera S PDK – it’ll hold onto plenty of its list price.

After three years or 36,000 miles that previous generation Porsche 911 would be worth 58.1 per cent of its new price, which is mightily impressive for an expensive car like this. Our experts predicted that the 991.2 Carrera 4S PDK would retain 57.7 per cent, so an equally strong showing
