Fuel economy

Petrol engines 23.0 - 28.0 mpg
  • Inescapably expensive to run
  • But relatively efficient all things considered
  • At least it’ll hold its value well

Consider that most Porsche 911 Coupes will cost in excess of £100,000 new once they’ve been gussied-up with options, and it’s inevitable that the money needed to run one will be beyond the means of most people.

Do not be tempted to run one cheaply, as it’ll come back to bite you when you try and sell it with a patchy service history and cheap tyres from a brand nobody’s heard of.

Servicing will cost a lot, but we’d strongly recommend having the work undertaken at an official Porsche retailer – that provenance will count for a lot at resale.

Talking of selling it on, many 911s retain their value well, so there shouldn’t be many tears when you trade in.

Consumables will also be pricey – particularly tyres to envelope those 20- and 21-inch alloy wheels, while brakes are also going to be dear. You could offset this by speccing the carbon ceramic ones when new as they should last the lifetime of the car.

Fuel consumption figures are all clustered between 25-30mpg depending on model - the Carrera S is the most efficient model, oddlly, while adding things like all-wheel drive will see petrol thirst increase.

Of course, you’re unlikely to drive a 911 carefully most of the time – a long stint of pressing-on is going to result in a figure close to the high-teens or low-twenties mpg-wise. The Turbo S promises 21mpg but we saw quite a bit less than that after some spirited driving,

There are far better ways of conveying to others that you’re concerned about the planet than driving a Porsche 911 Coupe.

Yes, in Carrera S guise it may only emit 205g/km of CO2 (206g/km for the Carrera 4S), which is low for a petrol-engined sports car capable to close to 200mph, but in the grand scheme of things it’s a high figure. That only increases with performance too - the Turbo S puts out 254g/km.

On the plus side, the 911’s longevity and exclusivity mean that the environmental impact of making it has far longer to be paid back than your typical mass-produced economy car.

In due course, Porsche is likely to unleash a plug-in hybrid version of the 911, but until then this is as good as it gets.

Don’t expect to be enthusiastically bear-hugged by a passing environmentalist.

Reliability

  • Should be more reliable than its predecessor
  • A well-honed, beautifully engineered car
  • Replacement parts will be expensive

It’ll be some time before we’ve a clear picture about how reliable the 992-generation Porsche 911 Coupe is, but both its builder and customers of the outgoing model will be hoping it proves to be more robust.

Inevitably, despite Porsche’s position within the enormous Volkswagen Group, many of the 911’s components are unique to the sports car brand and consequently will be expensive if they need to be replaced.

We’ll update this page as and when there’s a definitive line to report.
