Quote
..."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...

This tells me that Porsche is seeing a shift in the type of buyer for the 911. It's a buyer who's more interested in the panache of owning a 911 rather than actual driving of one.

I think that same analogy can be applied to all the luxury brands.

My first thought on this was that it is a variation of a modern awd system used for this purpose but reading the article it is based on sound sensors in the wheel wells. The resulting effect is similar though.

AWD+large, low profile, likely summer tires+non-dry conditions+add a dash of driver stupidity=crash!

Nothing more fun than being next to a Porsche or other “HP” car in a snowstorm-as long as they don’t go sideways and hit you! Fortunately nanny traction control usually stops them (usually literally).

1. Pretty sure panache has been more important than driving for a long time now.
2. It says what the shift was in the article: wider tires, more focus on dry performance.

This isn't about panache winning over driving. It's about people wanting bigger numbers rather than that make actual sense in the real world.

Another unneccesary safety device that will only raise insurance rates and increase repairs. All of this overengineering now is getting ridiculous.

Guys.

You all know this is a selectable mode, right?

Like... It's not a thing that's always on and impossible to defeat. It's a light that comes on sometimes, does literally nothing else unless you press the button, and then stops doing things the moment you press the button again.

I agree it shouldn't be necessary but you guys are whining like it's a horseman of the automotive apocalypse. Calm down.
