The latest Porsche 911 hasn’t been on sale long enough for us to gather any reliability data, nor has it been tested by Euro NCAP for crash safety. However, if the previous model is anything to go by, owners shouldn’t worry.

Porsche 911 reliability

While it’s too early to tell how a more technologically advanced 911 will fare in everyday use, Porsche itself has a good reliability record. The company didn’t make it into our 2020 Driver Power survey, but it did feature in the 2016 edition, where it finished 7th overall out of 35 brands.

Build-quality is a Porsche cornerstone and the latest 911 certainly feels as though it lives up to the brand’s reputation in this department. We’ll have to wait and see how its reliability pans out.


While there’s no official Euro NCAP rating for the Porsche 911, its safety credentials are impressive. There are more safety and driver assistance systems available than before, including automatic emergency braking (AEB) with pedestrian detection, lane-keep assist, front and rear park assist with optional 360-degree camera views, blind spot monitoring, night vision assist, lane-change assist and adaptive cruise control with stop/go functionality.

A new standard Wet setting is a clever addition to the driving mode line-up, using microphones in the wheelarches to tell when the road is wet; various car settings like traction control and electronic stability programme can then be adjusted to suit with the push of one button. The system works well in practice and is an extra step towards on-road safety that the 911’s rivals can’t quite match.

LED headlights come as standard to offer a great view of the road ahead in the dark or inclement weather, while optional LED Matrix versions further enhance forward visibility by dimming for oncoming traffic or the car in front, but lighting up everything else. The 911’s new signature rear LED light bar also increases visibility to other road users – as well as looking great.

There are two full-size front airbags, plus Porsche Side Impact Protection (POSIP) which adds side-impact protection elements in the doors, thorax airbags in the seat bolsters, plus head airbags in each door panel. The front passenger seat has ISOFIX points for a child seat and the airbags can be disabled for this purpose.
