.I don't believe there is a smaller performance difference between battery sizes. More KWh, more batteries, higher maximum current, faster possible performance. The small performance gap from X75D to X100D is due to Tesla wanting to maximize the performance gain going to the far more expensive P100D. This is just good business to maximize profit from those willing to pay much extra to have the fastest X.
P100D has 762 hp vs 518 for P75D. But without the extra 25 Kwh of cells a P75D wouldn't be as quick to 60 even if it had the 762 hp.
Tesla is current limiting the 75D so it's performance is not in the mid to high 3 second range.
I was referring to what is, not what could be or what is being limited. Most buyers have no idea about specs other than what Tesla lists on the website. The current stated difference beteeen X75D and X100D is ~.02 seconds.
