Dynamic / Adaptive chassis control (DCC / ACC)

[WhiteJames]

Dcc

Most important attibute of the Dynamic Chassis Control is that it's working every 10ms to create the optimum chassis damper tune for almost every roadway environment. Improving roadholding is one virtue; the other virtue is that DCC offers a supple ride.

The dynamic aspect of DCC may not be as apparent on the race-track where the dampers are predominantly in the their low speed compression range. Out in the real world where the entire depth of damper range is required - low speed and high speed compresion/rebound.

For those living where roadways are very good (Perth/Canberra), DCC differences may not be as stark. For instance: My drive from Canberra/Queanbeyan from the Farm to Cooma always starts in comfort. Sport can be had for almost all the drive from outside ACT border to Cooma with Sport or Normal fine for Cooma CBD as roadways are reasonably smooth in this township.

On the other hand; the drive from Sydney to Bathurst involved the use of all three modes: Sport/Normal/Comfort; with Comfort being the default setting for Bathurst City as roadways are much rougher than the CBD of Cooma. I certainly notice the difference between - Comfort - Normal - Sport - settings when driving around the block from my home on the South Coast of Sydney. Generally: Normal is the default mode for majority of the time. 2 months and 4,600km on I'd certainly recommend DCC option for a street driven vehicle. Definitely option this on any subsequent vehicles I purchase in the future. After having driven many Golf GTI's, the guys at Motor Magazine are also indicating that they wouldn't buy a Golf without DCC.

Only option I wouldn't buy is the MDI in the centre console compartment as it takes up practically all the glovebox space. My MKV GTI had the aftermarket OE Volkswagen glovebox fitted MDI that operates from the radio controls and re-charges the Ipod for $400 fitted, leaving room for the entire storage space in the centre console.

Well said. I find it interesting that people will spend money on MDI or Dynaudio but question ACC. Audio is nice to have but you buy a car for the drive (at least I thought that was how it worked?) so ACC is a great option to have. But each to their own of course.

I got it on my R with 19's, But I could definitely see it being something you could omit for the sake of $1500. (Which really is foxtel or phone bill paid for the year)

I just figured I'd go without a few dinners or something LOL

After owning a 05 WRX for the last 5 years, a 40 minute drive to the city, (bumper to bumper) is exhausting...even worse is the two hour drive from home to our holiday house , nearly 90 minutes on the freeway.....(i need to lie down for half an hour from exhaustion).
However, having sports suspension is a delight to drive in short bursts and around fast corners...
My point....sports suspension is great, but for the long highway trips its going to be a life saver for someone like me with a crook back...having said that, its an option i put first on my list after driving a gti for a whole day in comfort mostly....

If I could have afforded another option on the car, then it would have been the ACC.

I quite like the MDI, and definitely prefer it over the glovebox version, which to me is in an awful spot especially if you use the glovebox for holding things (e.g. some in mine: notepad, pen, tyre pressure gauge, torch, etc). When I had a MkV, the bin between the seats was hardly used and the cooling never worked anyway.

I openly posed the question of ACC to the senior salesman at my dealership when placing my order; he advised against it (surprisingly strongly) as an option of little value that just adds to the depreciation hit. Unfortunately I wasn't able to sample ACC on a GTI prior to placing my order (one dealership in SA, one car in the state at the time), so I didn't spec it. I do regret that decision now, as a softer ride around town would be the icing on the cake for my GTI. But it's still a fantastic car without it, and rides far better than many other sporty models I've driven recently.

I must be getting old and frail too lol cos that was my reasoning for getting it. Sport when the time suits, otherwise lazy old man for the rest Plus in my head I am hoping that the lazy lardy comfort mode will be enough to stop me driving like a total retard all the time!

It is quite often very hard to make the choice on some options due to the lack of demo's available. I had the same issue with the race seats.

It's not a bad option at all, I'd rate it more highly than leather and sunroof and is a pretty good price for what I is.

This thread is tedious.

LISTEN UP!

If you live in Sydney or anywhere else that has crap roads ..... GET ACC .... it makes a big difference and is a cheap option considering that you will use it and appreciate EVERY time to drive.

My previous car had 17" wheels, but despite the 18" on the GTI, this old timer has found the ride to be very comfortable on NSW roads.

But each to their own of course.

Agreed. I think it is easily forgotten by those that have ACC that the standard GTI suspension set up is spot on, and oh so right.

[G-rig]

The previous suspension was quite under dampened on both the Mk5 GTI and R32 IMO.

I guess it depends what you are used to. My current ride is an 04 Fiesta which is lowered and has 18's so the ride is considered by most who ride in it to be fairly firm. I've test driven an R with 19's and I can't say the ride was any appreciably harder than what I'm used to so am going without ACC.

Playing with the DCC settings on a section of roadway in northern NSW between Kempsey & Grafton, I had the opportunity to sample the speed of the DCC damping rates when striking a one-off large bump in both Comfort and Normal modes. Comfort mode had the dampers allowing the spring to hurriedly approach full compression until firming up and creating an almighty bounce upwards in the chassis, triggering the tyre indicator warning lamp.

A second trip along the exact same roadway in ‘Normal’ mode DCC didn’t exhibit this tendency to almost bottom out and then firm up causing a mighty bounce upwards. In Normal mode DCC – the instant shock was correctly damped against the spring rate, limiting the springs from compressing too far before DCC having to apply much firmer damping rates to prevent the springs from hitting the bump stops on full compression.

The Dynamic Chassis Control dampers are intuitive – but not instant as would be the case in a mechanical system as that found in a Koni – FSD damper for KW coilover that run varied rates of low-speed and high-speed damping compression rates. On the rare occasion, the Volkswagen electric motor Dynamic Chassis Control can be caught sleeping for that instant ¼ of a second – when in either extremes of Sport or Comfort settings – but much less likely the same scenario in the middle ‘Normal’ mode.

The DCC does a great job of keeping the Golf flat in corners without the need to resort to large diameter aftermarket adjustable sway bars that will crap up the one wheel ride. Add EDL and XDS electronic diff and the Mark 6 Golf GTI is an easy vehicle for the driver to traverse the hinterland tight twisting roadways - much easier than the older MKV GTI.

The DSG sport function on the Mark 6 GTI is nowhere near as aggressive as the DSG Sport function in the earlier MKV GTI – doesn’t hold onto the gears for what seems to be forever on the MKV GTI. You could even use it in town.

I'm sure I've already +1'd somewhere in this thread before for DCC, but I'm gonna +2 now... I took my car for a quick spin down to Church Point in Sydney yesterday, twisty little road, not great quality. DCC set to Sport and let me +2,+3,+4, etc for DCC. You'd have to have rocks in your head not to get it if you plan to do anything but city/freeway driving. Completely changes the character of the car. In combination with those awesome S2TPP shifters, I'd swear that wasn't the car I commute to work in daily.
