I got the impression the OP was looking for useful information on the ground clearance of the Model X - and whether or not anyone had taken up the task to research what could be found out. I don't see how curt answers like that help him or the conversation here.
I think we could be more welcoming to interesting topics, even if it means discussing something not yet released. When the first response is basically questioning the guy instead of pondering the topic, no wonder they go to "never mind" fast and run away. Just my opinion.
And on that note:
I mentioned 1.5-2.3 inches of difference between Audi sedans and Audi allroads of various persuation. They are good examples in that they are normal cars converted into cross-overs. Although they are slightly more positioned for the dirt than X is...
On the BMW side we can find a non-allroad example that might be relevant, the BMW 5 GT. It isn't positioned as a dirt road weapon, but more of a luxury "big car" for the lack of a better word. Just like the X vs. S, 5 GT is a higher riding, but also taller version of the 5. But apparently the basic difference in ground clearance there is only around 0.1-0.2 inches there, even though the car has a bit of a CUVish posture. That said, I think Tesla is aiming a little higher - literally - with the Model X, 5 GT is probably too much of a big sedan in its market positioning still to be the best comparison...
What about Mercedes Benz? The Mercedes Benz GLA would seem like a timely candidate for scrutiny, although from a different price point and size segment. Basic versions have 6.1-6.7 inches, the offroad 8 inches of ground clearance. The new A Class, on the other hand, around 4.5 inches - max 3.5 inch difference. Now, it has to be said the A Class has perhaps the "worst" clearance of its class, while GLA is best of class, so again, perhaps not the best comparison but still a competitive data point of cars based on the same platform - one a normal, another a cross-over.
Summary of ground clearance differences:
Audi allroads sedans vs. CUVs: 1.5-2.3 inches
BMW 5 vs. 5 GT: 0.1-0.2 inches
MB A vs. GLA: 1.6-3.5 inches
These are just very quick numbers I grabbed, to give some idea, so feel free to correct and add as appropriate if I made a mistake. But I think looking at those numbers, if Tesla has decided to go for added ground clearance and the battery slate is not hampering them too much, adding maybe two inches (50 mm) to the ground clearance seems plausible compared to the competition. Then again, it isn't completely unheard of to simply make a higher car, that sits nominally higher, aka the BMW 5 GT.
Please feel to add any other cross-over ground clearances from other cars / manufacturers!
As for analyzing the mule, that must wait for another moment for me... Feel free to pitch in all.
