Six airbags are standard, as is a sophisticated stability control system. There are also Isofix child seat-mounting points on each rear seat; an Isofix point on the front passenger seat is a cost option.
The options list doesn’t include some of the more advanced safety aids such as blindspot monitoring or lane-keep assist that are available on several rivals, but you can get adaptive cruise control, which will automatically apply the brakes if it senses an impending crash.
The 911 hasn’t been crash tested by Euro NCAP, so no scores are currently available.
An engine immobiliser and an alarm are standard, but if you want more protection you can pay for Porsche’s vehicle tracking system, which makes it possible to trace stolen vehicles across most of Europe. Thankfully, the 911 will be a hard car to steal; security experts Thatcham awarded it five out of five for resisting being stolen and being broken into.
