    Sand Driving

    Have read Gordon’s handbook and much wisdom here, and have done the beach/dunes numerous times, yet I still have a question about how the late model D4 performs in sand driving ... not sure if this was discussed here recently or not ....can’t find it.
    Basically it does seem that the engine revs higher for longer when running along the beach, even on the hard packed stuff, the car seems reluctant to change up a gear or two. Seems to sit at 2500-3000, in D with DSC off and Sand mode, all done in the right order.
    In the soft stuff I understand that it needs to wheelspin a bit and therefore hold onto the gears, but doesn’t explain its behaviour on the harder sand.
    Are the MY14+ cars setup differently, or is there another driving technique not documented?

    In my Disco Sport I find the same thing. Sand mode just holds higher revs all the time, and if you’ve got the transmission in D then that’s probably the smart thing for it to do. When I get on the harder stuff I switch to S and just manually bump the gears. You gotta pay a lot more attention than on the highway though.

    Sand mode changes the gearshift mapping (ie shift points) so it holds onto a gear for longer. The car doesn't necessarily know whether the sand you are on is soft, hard or in between (it probably could actually), so it just has the one set of shift patterns for sand mode. Perfectly normal.

    The transmission change points relate to the mode selected, not to the traction underfoot. If you select sand it will hold gears longer to maximise torque and power. This is irrespective of the current traction available. Select road/normal if you’re on hard pack and want to rev lower. That is what I do - just remember to slow and switch back!

    Back to normal mode sounds like a good plan! Thanks all!

    I believe that 90% of sand driving relies on the correct tyre pressure/choice and momentum, get those right first then worry about mode selection
