Only two wheels on the ground ?

There may be an obvious answer to this that I'm not sure of it, but somebody here will be.

In a scenario where the "Range Rover Sport" my11, is sat on its chassis with only two wheels on the ground and two off the ground, which drive mode should be selected to rescue the car. I'm thinking:

a) The rear wheels over a cliff edge with the rear wheels spinning in fresh air when in normal drive mode ?

b) The nearside wheels over a cliff/kerb/drainage channel with no contact with any hard surface and sat on the underbelly from front to back ? How would one re-mount the edge when the wheel line is parallel to the edge ? Steer further out until the front wheel can be turned inwards so that first point of contact is the tyre rubber ?

Thanks in advance.

Gary

If the vehicle is grounded and wheel spin is detected, the suspension will be automatically raised by approx 50mm to try to give ground clearance. If it's still grounded you can put your foot on the brake and press and hold the raise button for a few seconds. This will give you another 25mm maximum if available. If that doesn't get the chassis off the ground then you will need recovering by another vehicle.

In your cliff examples, I would suggest that you won't be able to drive out of either situation. You need rescuing.

The Terrain Response systems are very good but they can't help once you have the vehicle fully sat on the chassis such as in your cliff examples.

My advice is to avoid cliffs... 2012 SDV6 - it's missing a couple of cylinders

Thanks for that.

Must say I'm surprised and disappointed. I did expect that, in case a) at least, the front wheels could drag the vehicle forward, using one of the terrain modes, until the rear wheels made contact and then all four wheels would work together.

Makes driving on virgin snow a nightmare, methinks. Fortunately, that's not an experience I pursue. Smile

It might be a Land Rover (Range Rover) but it still must obey the laws of physics. I've had to recover too many Land Rovers who's owners mistook them for magic carpets.

It might be possible to drag the back end until the rear tyres make contact with ground. However, if the vehicle is sat on its chassis frame (or fuel tank more likely), it's likely that the front wheels would slip and spin. In rock crawl mode you'd have a fully locked centre diff but you'd still be relying on the front tyres to find some grip. No grip, no go.

With the case of tyres on one side in a ditch, the vehicle would be sat with the lower wishbones on the ground. You might be able to turn to wheel toward the higher side and gain traction to lift the nose back.on to the ground. Again, I'd use rock crawl to ensure the centre diff is locked. You'd be lucky not to damage the side wall of the tyres trying climb out of the ditch like this, however, if the edge is sharply defined.

Again, stay away from cliffs.

Just to prove that they can drive up very steep stuff, if not cliffs, see here:

The chap would have made smoother progress if he hadn't kept jumping off the throttle when the wheels spin. Traction control needs wheel spin in order to know what's going on. Impressive climb, none the less. 2012 SDV6 - it's missing a couple of cylinders

He'd have done a lot better without that idiot getting in the way....psychologically it would be causing him to lift the throttle off to avoid running into him. A steady throttle all the way would have done it. Never used a spotter in 30 years... Visitor from fullfatrr.com

One wonders why Rolo is asking this -is he thinking of driving off Beachy Head and changing his mind halfway over the edge? Surely RRS ownership isn't so much of a millstone that he wants to end it all! 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Usually when you have wheels off the ground, its diagonally or one corner, which the sport should deal with.

If you're in the situation where the chassis is resting on the ground and the wheels are not, you have done something badly wrong. Usually the friction of chassis on ground is greater than the traction you have available from the two wheels , so you will need a tow. We did manage it on a green lane in a 88" a few months back, but managed to shuffle out with some left foot braking and wriggling side to side with what traction there was.

That is the "cross axle" situation, which any modern Land Rover product with traction control shouldn't find difficult to get out of but in the TDi Defenders and Series Land Rovers could be a problem. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Yep, cross axle generally not a problem for the RRS so long as constant gentle throttle used. 2012 SDV6 - it's missing a couple of cylinders

It was last September when I reversed over the edge of this sunken vineyard by mistake. I wrote about it at the time on a separate thread but at the time was more concerned with how close I came to flipping the vehicle as I reversed down that slope. The vines are about 4 feet high, so I estimate that the grass bank was 10 feet. You can see the gouge I left in the grass on the left hand edge nearest the camera. In the process of reversing down, I ripped off the front bumper and filled the exhaust cowls solid with grass and soil. So I'd been pretty near vertical.

The reason I've opened this thread is that I've not really learned how I'd tackle a similar situation in future if I was unfortunate to loose wheel contact again. Not something I have any desire to repeat, I can honestly add. However, with mountain roads and snow, it's something I'd like knowledge of. It appears that reversing was my only option, I've been wondering ever since, especially when getting panic attacks 😂, whether a drive mode option would have enabled me to simply drive off.

Fortunately, I've no experience of near side wheels being off the ground, but I can imagine that this could being a more frequent problem. One sees deep concrete/paved flood channels at the side of some mountain roads, but they wouldn't be obvious when filled with snow.

I travel alone and in mountainous regions, or coastal regions where mobile phone cover isn't always good. I'm not an off-roader, but I'll drive on a well marked stone track, or across a coastal headland to wild camp, or photograph an estuary etc.

Thanks for your responses.

Sorry, cant upload image. However, there's two photos in the gallery that show the situation.

Seriously, if I were you I'd look at doing some sort of off road driving course. You would learn what a 4x4 is actually capable of (you'd be surprised) and as a bonus what you are capable of. No amount of internet knowledge will substitute for actual hands on experience.
