Has anyone figured out a way to disable the rear wing from raising up while driving? I have a hard time believing that any real downforce is created with the wing, it seems like more of a gimmic. On the Turbo GT, it starts to block the rear view.

I was wondering if you could pull a fuse, pull a plug or code it out in PIWIS.

Thank you.

 

The silence is telling me I'm the only weirdo out there considering this minor mod. It's akin to buying a GT3 and removing the wing, right?

 

I barely notice the wing deploying (since rear visibility is bad to begin with) so it has never really been an issue I've put too much thought into. The one time I did wish there was a way to disable the wing was last year after an ice storm when I wanted to prevent the wing opening while encrusted with ice. I failed to find a solution and the thing crunched itself open at speed. Luckily nothing broke.

 

encrusted ice story is kind of cool. they probably test it for some level of ice but like u i rather not have it crunch its way open if avoidable. but it is kind of cool that it did. it shows it has some strength, which it should if it is going to be stiff enough to provide some down force.

 

I’ve only had my TGT for a month. But have noticed that under heavy acceleration, the car is a little unstable (or maybe it’s just me!). Anyway, the wing must be considered necessary for stability. It does obstruct the rear window, but I’ve gotten used to it.

 

I had the rear wing fail in my base Coupe before I traded it for my Turbo Coupe. The car was noticeably unstable at high way speeds to the point where my wife even noticed it on a 500 mile road trip.

 

yeah, i don’t think they added a motorized spoiler for fun. i have a friend w an audi tt. it also has a spoiler that deploys, it stopped deploying at one point and the car was just squirrelly - according to my friend. rear of the tt and cayenne coupe aren’t totally dissimilar so no surprise that the cayenne needs a spoiler like the tt.

 

You guys are hilarious. The wing adds 40kgs of downforce at top speed. Cut the speed to highway speeds and it amounts to having a few 12pks of soda in the back. But I'm sure it feels like it adds a lot of straight line stability, especially on a 4900lb++ vehicle.

 

The rear spoiler (it isn't a wing or a "gimmic") is intended to reduce lift / negative pressure, not produce a material amount of downforce. It's there for the same reason cars like the Audi TT have them - do a quick search on the first gen TT and you will see for yourself. Really only a significant issue at speeds much higher than limits in most countries but equally not worth experimenting with. Ice isn't going to be an issue, the motors which extend and retract it are incredibly strong.

 

The Cayenne weighs 2x the old Audi TT. Its shape is quite a bit different from the aerofoil shape of the Audi TT. Most of the aerodynamics experienced on the Cayenne coupe come from the front splitter, rear diffuser and upper wing. If you want to compare to the Audi TT, the fixed spoiler should be sufficient, then again, most of the Audi TT fix was to adjust the suspension (front compression and rear rollbar) and add electronic stability control. In fact, they debated even adding the little fixed spoiler. The problem occurred during high speed turns while braking such as when exiting the Autobahn. It's nonsense to pretend the back end of a 5000lb SUV is going to suddenly start to hop around while driving down a freeway particularly at US highway speeds.

I think Porsche added the articulating wing to make the coupe seem more like a 911. If that's the case, it's a gimmick. If someone has some definitive information on the matter, I'd love to be educated. Until then, I'm still interested in the wing disable and how best to do it.

Edit: if the articulating spoiler was so important, how does the standard Cayenne manage to not fly off the road? How do the X6, GLE, RSQ8, Urus etc get by without stability issues?

 

there has to be a motor or two, seems like they could be mounted so they don’t engage the mechanism to operate the wing. the car would think it is raising and lowering the wing when it isn’t. just an idea.

 

You came in here to start a ridiculous fight over this. Take the rear center light out and the three bolts hooding in the panel and disconnect the two wing motor. It'll throw a code and an error right away.

If you pull fuse #3 in the second fuse box it'll also disable the rear spoiler from enabling. Eventually, it'll throw a code and an error.

 

I'm sorry to have offended, wasn't trying to fight over it, though I anticipated a bunch of opinions unrelated to the question at hand.

I appreciate the ideas. I've had the same ideas, but wasn't sure what will cause errors. Ideally I'd like to a find a simple fix that doesn't result in errors. Thank you for the input!

 

Look for someone who has PIWIS 3 and knows Porsche coding. Disabling the rear spoiler should not be difficult, even by changing the speed range of the car in which the spoiler is extended.
Unfortunately, I don't know how to code the Cayenne yet, but in various Audi Q8s I have changed the operating parameters of some functions many times, depending on the speed of the car. At Porsche, this logic should be the same.
