Most popular SUV's with good (highway) driving characteristics like X5 and Q7 are not considered 'real' offroad machines like Landrovers or Landcruisers mainly because of their lack of Low Gearing. I'm no expert but what I understand about the concept of low gearing is it gives you maximum torque and maximum control at low speeds.
Wouldn't it be possible to create the effect of low gearing through a software fix in the Model X which would use the instant torque of the motors while limiting top speed to about 30 mph. This way you could use the full travel of the accelerator pedal for maximum control. Assuming it's all 'fly by wire' that would be relatively easy.
Anyone have any thoughts if this could work? If this is possible it would be another awesome selling point for the Model X and would make the car even more useful. Not just for commuting to work or soccer practice but some real outdoor adventures!
Just imagine selecting the setting Ultra High on the air suspension and Ultra Low on the gearing, all from the comfort of the touchscreen, and nothing that will get in your way :-)
If this won't do the trick, does anyone have other ideas to make the Model X more of a rugged machine?
Electric motor torque at low RPM is already way more than any ICE can give you. No need for "low gearing". Model X probably could climb to a tree if it had enough traction.
I believe ArieK was thinking of a sort of "terrain" setting in the software.
That would allow for full use of the gas pedal without actually reach 0-60 in 4 seconds. I guess one would still need diff-locks to ensure all 4 wheels keep turning even on EV? Today starting diff-locks is possible with the flick of a button -no need to go outside and twist on the wheel hub. Diff lock Would be a great option.
For a terrain setting also useful would be hill descending control.
torst;
I believe traction and stability control handle that normally. As for hill descending, cruise control and regen will work AFAIK.

The Model X is clearly designed to be a family car. With the expectation that families will have teenage drivers, I would love to see a lot of governor...
