Porsche has a reputation for building durable cars. In 2016 – the last time Porsche featured in our annual Driver Power owner satisfaction survey, it finished 7th out of 35 brands. Like all Porsches, the 911 is superbly built and its strength means it should be very safe in the event of an accident.

Porsche 911 reliability

The current generation of 911 has been around for several years now, so any teething problems should have been eradicated. The latest ‘991’ generation of the 911 has yet to feature individually in the Driver Power survey, but its ‘997’ predecessor finished in 133rd place out of 150 cars – although it should be remembered that the newest of those cars is now over six years old.


The 911 hasn’t been subjected to Euro NCAP crash-testing, but it comes with six airbags, electronic stability control and tyre-pressure monitoring as standard. Options include adaptive cruise control and carbon-ceramic brakes, plus electronic aids that help to keep the car stable and more controllable at higher speeds. The four-wheel-drive models naturally add more grip and are safer in poor weather conditions.
