I’ve had my 2017 991.2 for about a month now and really like it. I’m confused about these two buttons. Does the shock absorber turn PASM on or does it just stiffen up the suspension? Also how, if at all, do the shock and sport buttons interact?

i do not have SC or PSE.

Thanks

 

The shock button will cycle between normal and sport operation of the shocks. The sport button changes various vehicle parameters including engine response and will also enable the sport shock setting.

 

PASM is always on. When you hit the button the shocks dampen motion more quickly (i.e. what people call ‘stiffer’ but isn’t really.)
.1s and .2s may be different (but, I doubt it.)
Without SC there is no interaction. They are independent. (At least this seems to be the case for our .1 wo/SC)
With SC, hitting sport also selects ‘sport’ mode on PASM. But there’s also a Sport+ setting for PASM.

 

Good question, as I’ve wondered about that as well on my 2018 991.2 C2. I thought I knew the answer, but it’s good to hear that my assumption was correct. So that brings up the question, why would anyone want to activate the sport shocks setting yet stay in non-sport mode?

 

No idea. But, the reverse - Sport mode, normal chassis - is my default for around-town driving.

 

Thanks. I’m still confused though. So are you saying when I hit the sport button it also activates PASM (ie the shock absorber button)?

 

Sport + will also activate shock absorber button, but Sport button will not.

 

worf928 is not correct. The shock button changes compression and dampening stiffness. The Sport and chassis mode buttons act independently on the car. The OP is misusing “PASM” - PASM is the name of the active suspension that the 991 has. The shock button switches PASM from stiff and non-stiff “chassis” modes.

To answer your question, I sometimes use non-Sport throttle mode but use stiff chassis when I’m driving around town with my girlfriend who complains when I accelerate too much.

 

LoL. I'm wrong but you just - barely - paraphrased what I wrote? And added a hint of jargon. Nice.

 

I thought the shock button was for when the passenger touches anything in the car you don’t like.

 

No, that is the ejection seat button.

 

Yes. Things like the shock button, auto start/stop button, and exhaust button are independent buttons that control only that one feature. The sport button is a “combo” button that will change numerous parameters to make the car more sporty.

 

Perhaps they like the stiffer suspension but prefer the more subdued throttle of normal mode or quieter exhaust with PSE off. That’s the beauty of customization.

I take it you have never driven a BMW M car? The customization is vast. Multiple settings for throttle response, steering effort, suspension stiffness, exhaust flaps, traction control, etc. All independently configureable to dial it in just how you want it.

 

I had an M4 for a while, various settings available, like blenders with all those settings, in the end it was still a blender.

OP, PASM is always on as mentioned, don't think about it as an on/off thing, don't think about it.

 

On manual non-SC cars,the sport button adapts the throttle and dis-engages the auto stop/start feature. With PSE, it activates PSE and adds the backfire farts on throttle lift.

I personally drive with the Sport off and PASM in firm all the time. I find the normal PASM setting to be a little to 'bobby / bouncy' over the kind of pavement undulations we have in PA. The firmer setting really eliminates any porpoising while not being harsh. I quickly tire of the backfires and crackles from the exhaust with the sport on. The difference in throttle mapping isn't enough for me to want to hear blattt, blatt, blat everytime I lift. I do keep my PSE on.
