(I'm the OP) My 2020 Scout has Off-road as a selectable mode (Eco, Normal/Drive, Eco, Off-road) on the infotainment panel screen which appears when I press the physical Mode button:
I observe (see details below) that Off-road mode actually makes the car in some senses LESS "sensitive", as it explicitly allows a bit more wheel slip, in order to avoid the anti-whatever systems making the car completely unable to move in the case where lots of stuff is sliding all over the place under the wheels.
I've driven my 2020 Scout up a moderately rutted snow, slush, and some ice covered mountain road, in normal drive mode, several times. I routinely drive on dirt roads (nothing too spectacular, though at times the 4x4 has given me the ability to pass where a front-wheel drive car might have had difficulty, and I appreciate those extra 3cm of ground clearance).
I've not even bothered to turn on Off-road mode since the very first months after I got the car new and was playing with it.
The manual says:
The following functions are integrated into Offroad mode.
▶ Hill descent assistant
▶ ESC Offroad
▶ ASR Offroad
▶ EDS Offroad
▶ ABS Offroad
Hill Descent Assist
The hill descent assistant (hereinafter referred to as assist system), with its automatic braking action on all wheels, ensures a constant speed is maintained on a steep slope when driving forwards and reversing.
During an intervention, the white warning light in the instrument cluster lights up.
The assist system is automatically engaged under the following conditions:
* The engine is running.
* For vehicles with Manual transmission the shift lever is in the neutral position and or the 1st, 2nd, 3rd gear, or reverse gear is engaged.
* On vehicles with an automatic transmission, the selector lever is in the R, N, D/S position or in the Tiptronic position.
* The downhill gradient is at least 10 % (when driving over sleepers, the limit can briefly drop to 8 %).
* Neither the accelerator nor the brake pedal is pressed.
Driving speed
Initiate the downhill descent at a reasonable speed of approx. 2 - 30 km/h, the assist system constantly maintains this speed as you travel downhill.
If a forwards or reverse gear is engaged on vehicles with a manual transmission, the speed must be high enough to avoid “stalling the engine”.
The driving speed can be changed by pressing the brake or accelerator pedal.
This is true even if the shift lever is in the neutral position and the selector lever in the N position. Engagement of the assist system is resumed after the pedal is released.
ESC Offroad
ESC Offroad makes driving on dirt roads easier, as no ESC interventions occur when the vehicle is slightly over or under steered.
ASR Offroad
TCS Offroad makes starting and driving on an unpaved surface easier as it partially allows wheel-spin.
Note
When disabled, TCS » page 211 Offroad mode works without the support of TCS Offroad.
(The manual doesn't explain why the section is called "ASR" but the text of the section use "TCS". I suppose that TCS is Traction Control System. I guess that ASR is Anti-Skid somethingoranother. I guess they're equivalent?)
EDS Offroad
EDS Offroad supports the driver when driving on a surface with different grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with the intervention of the standard EDS system.
ABS Offroad
ABS Offroad supports the driver when braking on an unpaved surface (e.g. gravel, snow etc.).
The system generated by a controlled locking of the wheels braked wheel before a “wedge” of piled material, which shortens the braking distance.
Maximum system efficiency is achieved when the front wheels are in the straight ahead position.
