Where did you read that the car lowers at speed? AFAIAW the suspension only lowers when you open the door to get out of the car and then goes back up once you are in and the doors close...

 

Definately lowers at speed to increase aero's, not sure by how much.

 

It does lower at speed (60mph+, from memory). It's only a tiny drop in the suspension. Again, I think 10mm is the figure that I recall reading. The drop for passengers when parked is clearly much more than 10mm.

So I don't think one would notice such a small variation in ride height at speed and there is no indicator on the screens either. In the literature it says it's designed to create greater fuel economy.

I can check if it's challenged but I do have other things to be getting on with

Hmm I never noticed this at all so had no idea it had this characteristic

:lol: true say!

 

The low setting is indeed for entry/exit. You can manually select this low height while driving and low speeds as well, but above a certain speed it will return to normal.

As for the 10mm drop while above a certain speed, I can't find a reference for that.

 

Hi,

I couldn't find a feature like the one you're describing anywhere in topix, here's the documentation:

Air Suspension Control

The driver can manually select, using the air suspension soft keys, one of four ride states:

• NORMAL - this height is the normal operating height of the vehicle
• OFF-ROAD - this is higher than the on-road height and provides improved ground clearance, approach, departure and break-over angles up to speeds of 80 km/h (50 mph).
• ACCESS - this is lower than the on-road height and provides easier access, egress and the vehicle loading.
  Locked at access - this allows the vehicle to be driven at the access height at speeds up to 40 km/h (25 mph) to provide increased roof clearance in low car parks, for example.

Vehicle height changes are restricted if the CHCM receives a 'Door Open' signal and the speed is less than 8 km/h (5 mph).

Normal Height

This is the normal ride height for the vehicle.

Off-Road Mode

Off-road height can be selected from normal height by pressing up the 'Off-road' soft key at any speed up to 70 km/h (43 mph). The message center will display OFF-ROAD HEIGHT SELECTED.

The Off-road height is dependent upon vehicle speed. The Off-road height selected will be confirmed with an Off-Road (1) or (2) soft key in the TS display when in the 4x4 info menu.

Off-Road 1 height is 25 mm (0.98 in) above normal height up to speeds of 80 km/h (50 mph).

Off-Road 2 height is 46 mm (1.81 in) above normal height up to 5speeds of 50 km/h (31 mph).

The suspension height can change automatically between these heights.

Off-Road 2 can be selected when at Off-Road 1 height by pressing up on the off-rad height when traveling less than 40 km/h (25 mph). To select normal height, pressing the 'normal height' soft key (2) or increase the speed above 80 km/h (50 mph).

Access Height

Access height provides easier entry, exit and loading of the vehicle.

Access height can be selected at any vehicle speed. When access height is selected, the response of the air suspension system will depend on the vehicle speed:

• If the vehicle speed is more than 20 km/h (12.5 mph), the CHCM will wait for up to one minute for the vehicle speed to be reduced. The access mode indicator and the lowering indicator will flash while the CHCM waits for the vehicle speed to be reduced; the Normal height indicator will remain illuminated. If the vehicle speed is not reduced sufficiently, the access height request will be cancelled after a minute.
• If the vehicle speed is less than 20 km/h (12.5 mph), the CHCM will lower the suspension to a part lowered height and will remain at this height for up to one minute. The normal height indicator will extinguish as the CHCM lowers the suspension to the part lowered height. The access height indicator and the lowering indicator will illuminate. When part lowered is reached, the lowering indicator will flash. If the vehicle speed is not reduced to less than 8 km/h (5 mph) in the one minute period, the access height request will be cancelled.
• If the vehicle speed is less than 8 km/h (5 mph), the suspension will be lowered to access height immediately. The access height indicator and the lowering indicator will illuminate. When the access height is reached, the lowering indicator will be extinguished.

Access height may be selected up to 60 seconds after the ignition is turned off, or for a few seconds after the driver door is opened.

The suspension will rise from Access height to Normal height when the speed of the vehicle exceeds 7 km/h (3.34 mph) for three seconds or when the vehicle exceeds 15 kmh (9.32 mph).

Locked At Access Height

Locking the suspension at access height allows the vehicle to be driven at low speeds with the suspension locked at the access height. This allows the vehicle to be driven in low car parks, for example. with increased roof clearance.

When the vehicle is at access height and traveling less than 35 km/h (22 mph), press the lock soft key for longer than one second. The system lock indicator (5) will illuminate and SUSPENSION LOCKED AT ACCESS HEIGHT will be displayed in the message center.

To cancel this mode, press the lock soft key again or increase the speed to 40 km/h (24 mph).

Automatic Height Change Warnings

When the suspension is locked at access height, the CHCM will change the suspension height automatically when the vehicle speed exceeds 40 km/h (24 mph). The control module issues a warning to advise the driver that the vehicle is approaching the speed threshold when the speed reaches 35 km/h (22 mph). The IC sounder will emit a chime, a message will be displayed in the message center and the normal height indicator and the raising indicator will flash.

The warning is removed when the vehicle speed is reduced.

Auto Access Height

Auto access height can be enabled or disabled, via the vehicle settings/set-up in the message center configuration menus.

If auto access height is enabled, the suspension will be lowered automatically to allow for easier access, when the vehicle is parked.

The following conditions will apply:

• The suspension has to be at the normal height setting.
• The Terrain response system has to be set to the Automatic setting, General program, Dynamic program or the Grass/Gravel/Snow program.

NOTE: Auto access height will operate more quickly and smoothly if the Electric Parking Brake (EPB) is applied and the brake pedal is completely released.

Auto access height will initially lower the suspension up to 15 mm below the normal height setting, during any of the following events:

When the vehicle is stationary and any of the occupied seat belts are unbuckled.
The ignition is switched off.
When a door is subsequently opened, after the initial lowering of the suspension, then auto access height will lower the suspension to the lowest setting. The lowest setting is 40 mm below the normal height setting.

NOTE: If a door is not subsequently opened, after the initial lowering of the suspension and the vehicle's speed exceeds 40 km/h (25 mph), then the suspension will return to the normal height setting.

Auto access height will lower the suspension to 30 to 35 mm below the normal height setting, if a door is opened before any the following events occur:

• Before any of the occupied seat belts are unbuckled.
• Before the ignition is switched off.

The air suspension system's access height soft key can be pressed to lower the vehicle to the full access height, if the air suspension system is still active.

Normal driving will automatically return the suspension from access height to the previous setting. Normal height can be selected by pressing the up arrow on the suspension system's raise/lower soft key.

Auto access height can be activated up to 90 seconds after the vehicle becomes stationary.

Auto access height will only operate once for each time the vehicle becomes stationary. If further operations are required while at the same location, use the message center menus to disable and then enable the feature again. Alternatively, drive the vehicle at a speed above 7 km/h (4 mph) for 3 seconds or at a speed of more than 15 km/h (9 mph).

NOTE: This also applies in the event that the vehicle has been stationary for more than 90 seconds without activating auto access height. If a door is opened after 90 seconds, then an 'Auto Access timed out' message will be displayed in the message center.

Auto access height will not operate in the following conditions:

• The suspension has entered into extended mode.
• The vehicle is on a steep incline/ decline, or on a very uneven surface.
• There are not sufficient air reserves in the air suspension system, to lower and raise the suspension. In this event, an 'Auto Access temporarily not available' message will be displayed in the message center, when a door is next opened.

 

The following is copied and pasted from page 16 of the brochure I recently downloaded from the JLR (U.K.) site

CAPABILITY IN ALL CONDITIONS
Combining luxury and refinement with world-renowned all-condition capability, Range Rover continues to be leading-edge. Range Rover Velar offers new levels of style, whilst its unique Land Rover technologies and optimised geometry secure its position at the forefront of all-terrain capability.
Land Rover's patented Hill Descent Control (HDC) is a standard feature. It assists the driver with controlled descents of difficult slopes. It does so by maintaining a constant speed and applying braking separately to each wheel. Hill Launch Assist, which also comes as standard, ensures the vehicle doesn't roll backwards as it pulls away on an incline. The vehicle also utilises Gradient Release Control, which again comes as standard, and is designed to prevent the vehicle accelerating too quickly on a steep incline when the driver releases the brake.
ELECTRONIC AIR SUSPENSION
A sure-footed, composed drive is completed by the latest optional Electronic Air Suspension*, which provides exceptional wheel articulation and poise. It changes the vehicle's height quickly, allowing cross-linking of the diagonal wheels to keep all four wheels on the ground on very
uneven surfaces. Added to which, it makes loading heavy objects into the boot easier as you
can alter the vehicle's height by +/- 50mm to suit your needs. These functions can be operated via the key fob, 10" Touchscreen or button in the loadspace area**. The Speed Lowering System also uses the Electronic Air Suspension to reduce aerodynamic drag and fuel consumption at cruising speeds by lowering the vehicle by 10mm from normal ride-height when the speed reaches 65mph.
ALL TERRAIN PROGRESS CONTROL
All Terrain Progress Control (ATPC) is a state-of-the-art optional system that enables you to set and maintain a steady speed in challenging conditions such as slippery surfaces, including: mud, wet grass, ice, snow and dirt roads. Operating like a cruise control system, it functions between 1mph and 18mph, enabling you to maintain full concentration on steering and finding a path through obstacles.

Now if we could get the brochure quote

"The Speed Lowering System also uses the Electronic Air Suspension to reduce aerodynamic drag and fuel consumption at cruising speeds by lowering the vehicle by 10mm from normal ride-height when the speed reaches 65mph."

Into the manual, there'd be no ambiguity

 

¯\_(ツ)_/¯ that would be too straightforward, quig! :lol:

 

Nice.

 

Thanks for the reply's, it looks like the car will lower by 10mm at over 65mph, that confirms what the salesman told me on the test drive, and at only 10mm that explains why it is not really noticeable.

 

Do you get air suspension on Petrol models? I have been on the builder and the option isn't there - but when you go into the description it shows coil suspension!

Also - what is the realistic MPG on 21rims on a petrol model?
