Cruise control, the automatic speed control function, is integrated as standard in all 911
Furthermore, the system increases the braking readiness when it recognises that the distance to the preceding vehicle is shortened. It will also warn you of a detected risk of collision with acoustic and visual signals.
In addition, the system briefly jerks the brakes and, if necessary, initiates targeted braking, with any braking pressure applied by the driver being increased within certain system limits.
The optional Lane Change Assist system uses radar sensors to monitor the area to the rear of the vehicle and the blind spots on either side. Above a speed of 15 km/h, the system issues a visual signal in the mirror to inform you that vehicles are approaching from behind or entering one of the blind spots. Lane Change Assist improves comfort and safety, particularly on motorways. However, the system does not actively intervene to control the vehicle and can be deactivated at any time.
ParkAssist at the front and rear and the reversing camera are fitted as standard to all 911
The camera-based speed limit indicator informs you of speed restrictions and the start and end of no-overtaking zones on the screen in the instrument cluster and on the PCM screen.
* Data determined in accordance with the measurement method required by law. Since September 01, 2017 certain new cars have been type approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel consumption and CO2 emissions. From September 01, 2018 the WLTP will replace the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel consumption and CO2 emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. This may lead to corresponding changes in vehicle taxation from September 01, 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Currently, we are still obliged to provide the NEDC values, irrespective of the testing method used. The additional reporting of the WLTP values is voluntary until their obligatory use. As far as new cars, (which are type approved in accordance with the WLTP) are concerned, the NEDC values will therefore be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics. Additionally, weather and traffic conditions, as well as individual handling, can affect the fuel consumption, electricity consumption, CO₂ emissions and performance values of a car.
