Available as an option in conjunction with Porsche Doppelkupplung (PDK), this enhanced version of cruise control actively regulates the speed of your vehicle in line with the speed of the vehicle in front. A radar sensor scans the road ahead up to a distance of 200 m.
If Porsche Active Safe (PAS) detects that your vehicle is approaching the vehicle in front too quickly, the system issues an audible and a visual warning. Where necessary, this may be accompanied by a brief jolt of the brakes and the initiation of targeted braking. During this process, any braking by the driver is boosted to achieve the maximum braking force that the system is able to provide.
With the new 911, coasting is now possible even while adaptive cruise control is active.
