D4 air suspension question.

[Disomania]

The FAQ has several modes listed for air suspension, including a 'high speed' mode.

Now, several years ago, when it was only on RR, they used to list it in the owners handbook and say it would work at 80kph+ automatically.

The book for the D4 only mentions 4 modes, access, normal, off road and auto extended off road. I know the dealer mode is there too from what the forum and dealer have said.

So, my question is simply this:

Do all the modes in the FAQ exist for ALL D3/4/RRS or are they specific to the RRS? A search on the interwebthingy is not that helpful, just point to the FAQ!:confused:

[101RRS]

My RRS has Access, Onroad, Offroad, Extended, Super extended, and Motorway Cruise which is half way between Access and Onroad (need to be over 160 kph for a few seconds for it to activate - deactivates at 130kph)

The D4 does not have highway mode.

[Graeme]

The D3/RRS/D4 indeed have the same speed modes including high speed mode. Prior to Terrain Response the Range Rovers had highway mode which lowered at a much lower speed, with early L322s lowering at 100 kph. High speed mode at lower speeds (not available as standard) certainly improves handling - I can't vouch for 160 kph though. Lowering by 50 mm is even better as long as there are no bumps.

[WhiteD3]

Graeme, I'm sure my D3 didn't have the highway squat mode. Not sure about the D4 but I didn't think it did.

I know a guy, who knows a guy, who knew a guy who has a car very similar to my 3.0L D4......

I believe that car may have exceeded 160 on a couple of occasion....

But I'm led to believe that there were no indications, sensations or noises (warning bells) that would lend one to think that the car had lowered or selected a different mode.


I know the handbook says that it will....but......

:D

Someone must have stolen my D3 at some stage & on a long straight with relatively new tarmac, driven it several KPH over 160. It took some time (several seconds but not 30) for the car to slightly lower. I have heard rumors that there were no bells or lights when this happened.
I am also told that once the speed dropped down below 130 120 there was no discernible lift in the suspension.
I believe the thief stopped shortly after this & the height looked as per normal on road.
Once this dirty rotten scoundrel did the same exercise again going the other direction (only a bit quicker) he could say the car does seem to drop slightly but again some time after reaching 160. The mongrel also reports that the car is very stable & fairly quiet at this alleged speed.
Once the rotter had been captured & his sunglasses removed I decided to let him of with a warning from my wife.
That wiped the grin off his face!
Thankfully my D3 has not exceeded 110kph since this unfortunate event took place several months ago.

My L322 lowers to highway height at 80 and the light on the display comes on to let you know and then it returns to normal once you go below 80.I have driven it numerous times at 160 and the steering gets heavier and the suspension gets harder. Pat

how dose your suspenon get harder ???? it gets fermer cos of fast rebound settings in the shocks,

[CaverD3]

The lower mode was only on very early model D3s AFAICR.

[Graeme]

The WSM from Topix for the 2007 D3 states that it lowers 20 mm.

Whilst I can feel mine lower (using Llams) when doing 100 and be aware of the lower driving perspective, I'm not so sure I'd be in a position to monitor it at 160.

[roamer]

Wonder if the nav screen on 4x4 would show it altering height
It does show raising/lowering for other settings

So, the jury seems to say it DOES have a 'highway' mode, but it could work at 80 or 160!

Only way to see would be turn the camera's on on a HSE and watch the pretty 4 corner picture as you drive to speed - but let me guess... anything over walking speed it turns off!

[Graeme]

Terrain Response suspension systems only lower to high speed height after sustained 160 kph. The 80 kph and 100 kph were for earlier air suspension systems.

[Disomania]

Damn. Oh well. Might have to go get the llams thingy so I can set the ride height myself.

What is wrong with normal onroad height for highway driving?

On the highways around here you almost need offroad height ;)

That would be a "highway" by name only! :cool:

Nothing on a smooth straight road. On some of the bumpier roads with corners, the D4 can feel a little 'floaty'. Dropping the suspension a tad will lower the CofG a bit and make the suspension a bit taughter so less body roll when cornering.

And of course it adds another toy to play with;)

Maybe you need a Range Rover Sport:)

Come on Garry,the D3/4 RRS are second rate tow vehicles and thier wheels fall off and then they blow up and no one can fix them because they only have 3.0ltr engines where's is a fact you need a 6 cylinder to travel Australia,the 100series TD is the yardstick that inferior junk is measured against.:p.

Ha ha - but I was commenting on Disomania's comment about the D4 wallowing around on bumpy roads etc. If he had a RRS you would not get the wallowing feeling and have to lower the suspension - after it is a Sport - the badge on the back says so :D.

I actually though you posted on the wrong thread and you meant to put it in the D4 is a Crappy Tow Vehicle thread.
