Acceleration - 2021 4S Cross vs 2024 GTS

[Paint_To_Sample]

Driving in sport plus messes up the wheel alignment, if you use it often and above 90km/h it will cause premature (uneven) wear on the tires. I would go as far as severe damage. Check multiple threads on the forum (and even the car’s manual) on this. Just so you know.

It’s not so much that it “messes up the alignment” - there is a perfectly valid reason to increase negative camber (handling in corners). I think what you are trying to say is that sport plus puts the car in its lowest possible configuration, which, of course, will result in more negative camber and wear the inner edges of the tires faster.

Regarding “at which speeds”, this isn't accurate - the car (at least in the US) automatically defaults to the lowest ride-height (eg, Sport Plust ride height) when you exceed [75mph] (someone keep me honest here) to optimize aerodynamics. So really nothing you can do about it when you are driving fast. Further, I am not aware of any other reason that speed, in and of itself, would independently impact wear at a given camber angle.

As far as I'm aware, the automatic lowering at speed goes low (1 step down), not the lowest (2 steps down). Range mode is also 2 steps down and can incur the same camber + tire wear issues over long distances

My lease on a 2021 4S Cross Turismo came to an end beginning of this year - I got a great deal on a new (old shape) GTS Sport Turismo discounted around 25%

I’m finding the GTS feels noticeably slower accelerating from any speed

The 4S felt quite violent - The GTS just does not have that ‘shock and ore’ feel

is this normal or could there be a problem with the car?

The GTS is night and day above any 4S. 0 - 60 in 3.7s.

Perhaps some limiting factor at play on the car you drove rather than a problem.

Sport Plus and Range drive mode set the ride height to the lowest settin "Low" (2 down). Height is fixed in Range but can be manually adjusted in Sport Plus. Normal and Sport drive mode have the default height setting of medium.

Auto height is 'Lowered ' (1 step down).

None of the drive modes alter the camber of the wheels. The only thing that changes is the ride height and PASM setting (comfort to hard).

I use range mode extensively and does not in my experience lead to undue tyre wear. 20K miles on my 4S and currently 8.5K on my 1 year old GTS .

Auto height is 'Lowered' and not 'Low' when in Normal drive mode.

Depending on country the chassis height is at medium regardless of selected drive mode - Australia being an example I think.

The i icon on chassis height states this.

I will have to confirm next time I am in the car but my GTS definitely defaults to “Low” setting (the same as Sport Plus) at certain highway speeds…

I found this in the literature (but it is specifically in reference to Cross Turismo…

… I am fairly certain the GTS does it at something closer to 140km/h as I don’t often travel at 180km/h, but as I said, I will confirm next time I have the opportunity

At excessive (non-legal) speeds all Taycans will lower to the low setting if air suspension is installed. Can't comment on the new Adaptive Ride - it may behave differently. Depending on region (local regulations) this height adjustment may be limited.

I believe NA / USA/ EU all behave the same.

I don't drive beyond the limits and so my GTS ST when in Normal or Sport will adjust to lowered only unless manually adjusted. The GTS already rides at a lower height by default.

I have a new loaner Gen 2 4S ST this morning and it behaves the same.

I can confirm this. I don't have a GTS, but I do have the GTS chassis software. I was just on the highway going a steady 75mph in Normal drive mode. I turned the knob to Sport and the car started lowering to "low" (double upside down caret). I then switched back to normal and the car started going back to "lowered". Also, it looks like the GTS wants to be in "lowered" if in Sport drive mode between 0-60mph.

So it looks like the GTS chassis settings acts a little differently than the other trims?

thanks for confirming, I often drive in Sport so, yes, that makes sense that the speed dependent lowering differs based on which drive mode you are in.

I had no idea a GTS defaults to lowered in Sport mode below the first speed threshold (55pmph), then goes to low beyond that.

I can confirm this. I don't have a GTS, but I do have the GTS PASM software. I was just on the highway going a steady 75mph in Normal drive mode. I turned the knob to Sport and the car started lowering to "low" (double upside down caret). I then switched back to normal and the car started going back to "lowered". Also, it looks like the GTS wants to be in "lowered" if in Sport drive mode between 0-60mph.

PASM controls the electronic dampers and not the suspension height.

Air suspension is separate.

On cars with no air suspension PASM can be optioned.

https://presskit.porsche.de/specials/en/porsche-fahrwerkentwicklung/index.html

When stationary Sport = Lowered + PASM Sport and Sport Plus = Low + PASM Sport Plus - sad as I am I checked this morning on my GTS ST.

Height adjustment which is speed dependent will be set at prescribed speed thresholds (noting that in some regions this may operate differently).

None of the drive modes alter the camber of the wheels. The only thing that changes is the ride height and PASM setting (comfort to hard).

It may not be a deliberate intention but in lowering the car is an inevitable consequence of the suspension geometry, so lowering the car will always increase negative camber.

It is also possible, certain in the case of the GTS and likely in others, that the spring rates using the 3-chamber air suspension as well as the damper rates and speed related changes are different between model specs, and countries, even if the display "normal", "sport" etc is the same.

We know from Porsche marketing that the GTS suspension settings are "more sporty" but it wouldn't be a surprise if the Turbo S was too, for example. With the same hardware substantial differences in behaviour can be programmed into the springs and dampers.
The suspension geometry, however, is hardware fixed.

 

[D00notD00d]

as previously stated - 99% of driving was in sport +

It was a company car, so did not care

Agree, it killed my tires on the 4S completely

I thought it was dangerous wear at the time and a fault I needed a full set of new rubber - I think it first happened at about 10k miles.
it Looked like something had rubbed inside edge of tire completely away

The inside edges do wear a lot more. And you tend not to notice.

How did you get the GTS chassis software on your car?

How did you get the GTS chassis software on your car?

Via PIWIS. The process is beyond my ability of simple ECU coding, but if you’re interested I can forward you the info of the guy who coded it for me.
