Porsche Debuts World-First Wet Mode on 992 Models

Porsche Wet Mode: How It Works

The 2020 Porsche 911 is chock full of new technology worth bragging about, but a sure standout for driver safety is the debut of the world-first Porsche Wet Mode system. Included on every model of the next-generation 911 lineup, the system identifies wet driving conditions and offers better handling without sacrificing power in the process. Join us as we delve deeper into the 992’s new Porsche Wet Mode system and how it works.

Automatic Road Condition Monitoring

Unlike the technology used to manage rain-sensing windshield wipers, Porsche Wet Mode can identify wet road conditions after raining has ceased. That’s because the system uses tiny acoustic sensors embedded in the vehicle’s front wheel housing to monitor the amount of water that’s kicked up from the road into the front fender.

Once the system determines a high risk of hydroplaning, it automatically pre-conditions the Porsche Stability Management (PSM) and Porsche Traction Management (PTM) systems to respond earlier and more sensitively. The system also triggers a notification in the instrument cluster recommending the driver activate Wet Mode manually.

Activating Wet Mode

Drivers can activate Wet Mode using the button bar above the center console. With the Sport Chrono Package, Wet Mode can also be enabled using the mode switch on the steering wheel.

Activating Wet Mode allows the system to make more drastic adjustments to prepare for potential hydroplaning. PSM, PTM, adaptive aerodynamics, Porsche Torque Vectoring Plus (optional) and drive responsiveness are all adapted for optimized driving stability.

When moving at speeds of about 56 mph and above, the variable rear spoiler extends to “performance” position, cooling air flaps open, the accelerator pedal characteristic is made flatter and PSM Off and Sport mode are deactivated. Torque build-up is also remapped for smoother delivery. On the all-wheel-drive 911 Carrera 4S, the system pushes more power to the front axle to aid in stabilization.
