We have been innovators not only in production installation, but also in airbag technology. Porsche set the benchmark by introducing a non-azide gas generant based on an organic propellant. This makes the driver airbag lighter and more compact, and also makes it easier to recycle. The 911 models benefit from airbag technology that has been improved further still in the form of full-size airbags for driver and passenger which are inflated in two stages depending on the severity and type of accident (e.g. frontal or offset frontal). In less serious accidents, the airbag is only partially inflated, thereby minimising discomfort to the occupants.

In addition to the central airbag control unit on the transmission tunnel, a pair of impact sensors are located near the headlights. This allows a crash to be detected and evaluated far sooner and with considerably greater accuracy.

All 911 models are equipped with Porsche Side Impact Protection System (POSIP) as standard. It comprises two airbags on each side instead of the usual one. An integral thorax airbag is located in the seat backrests, while the door panels each contain a head airbag. With each having a volume of approximately 8 litres, the thorax and head airbags offer excellent protection in the event of a side impact. They have also been shaped to protect the occupants of 911 Carrera Cabriolet models, irrespective of whether the hood is up or down.

The head restraints are integrated into the backrest. Also featured as standard are an energy absorbing steering column, three-point seat belts with height adjustment (Coupé models only), front seat-belt pretensioners and force limiters, energy-absorbing elements in the dashboard and flame-retardant materials throughout the interior.
