Extraordinary excursion with the new 911: through the French Atlantic • Porsche Wet Mode in detail • Rebels in the rain: the R Group • Le Mans 1987: the starred helmet of Hans-Joachim Stuck • WEC: wild ride to clinch the title early–in 9:11 Magazine.

“Wet Mode was developed to provide the driver with consistent support in wet conditions. It does not restrict the maximum power of the engine or limit the top speed, and should therefore also not be used as insurance for driving too fast in very wet conditions. Instead, it should be seen as an assistance system in the truest sense,” says August Achleitner, who has been head of the model series for many years. Porsche Wet Mode can automatically detect a wet road and warn the driver about the risk of aquaplaning. For this purpose, acoustic sensors in the front wheel housing detect swirled-up spray water. This makes it fundamentally different from windscreen wiper rain sensors, which only react optically to water droplets on the windscreen independently of the road conditions. This is because there may still be standing water on the road even when a rain shower has passed.

If the system detects a wet road surface, the response behaviour of the Porsche Stability Management (PSM) and Porsche Traction Management (PTM) systems is preconditioned. Both systems then intervene earlier and more sensitively than before. In addition, a warning is shown on the display on the right next to the rev counter. This informs the driver of detected wetness and recommends that the driver switch manually to Wet Mode. The corresponding function can either be activated in the new button bar above the centre console, or is integrated in the mode switch on the steering wheel with the optional Sport Chrono Package.
