..."People drive too fast in the rain and are not aware of how close they are to the aquaplaning threshold," Morbitzer said, adding this was especially true for 911 customers......The best solution was to simply reduce speed and switch to the slow lane, but Porsche 911 drivers are not accustomed to this ...
...All new 911s will now come standard with a new safety system. Miniature microphone sensors analyze indirectly the intensity of the water on the road splashed up into the front wheel arches. Depending on the current speed, the vehicle can recommend the driver to activate the so-called "wet mode."
If activated, the vehicle starts to prepare itself for potential hydroplaning. Engine torque buildup is reduced, its distribution biased to the smaller front wheels for greater stability, and aero flaps open to create greater downforce. Actuating systems for safety features like Porsche stability management (PSM) and Porsche traction management (PTM) are lowered...
