The EPA rated range was 265 for the S 85; it was right on the mandatory EPA window sticker. Sorry, Tesla can't decide to change it. ;-)
Bumping this up one more time because now we have official EPA range numbers for the Model S 75D.
Model X 70D (never built) vs Model S 70D
220 miles vs 240 miles (91.7%)
Model X 75D vs Model S 75D
237 miles vs 259 miles (91.5%)
Model X 90D vs Model S 90D
257 miles vs 294 miles (87.4%) <<<----------?????????
Model X P90D vs Model S P90D
250 miles vs 270 miles (92.6%)
So, therefore, Model X has approximately 92% of the range of the Model S, strongly suggesting that the Model X 90D range is approximately 270 miles EPA. The currently listed 257 miles range makes no sense at all. The X 90D has the same active spoiler as the X P90D so that can't be the explanation for the discrepancy.

If you look at what people are posting for their 90% SOC in X90D it comes out to about 265-268 miles given 100% SOC

Still Trying to Figure This All Out
I have not tried 100% soc of charge yet. I certainly well need to long before a long winter trip in the mountains of NV where one leg is greater than 220 miles in the dead of Winter with lots of elevation changes and no opportunity of super or destination charging. Not only that but we will be going to a place where the sentiment is anti EV so if we don't make it easily, we will shame the Tesla community. Such pressure.

Bumping up now that we have Model S and Model X 60D variants back on the website:
Model X 60D vs Model S 60D
200 miles vs 218 miles (91.7%)
Model X 70D (never built) vs Model S 70D
220 miles vs 240 miles (91.7%)
Model X 75D vs Model S 75D
237 miles vs 259 miles (91.5%)
Model X 90D vs Model S 90D
257 miles vs 294 miles (87.4%) <<<----------?????????
Model X P90D vs Model S P90D
250 miles vs 270 miles (92.6%)
So, once again, one of these is not like the others. Tesla seems to be sticking to a 91.5%-91.7% relative range X vs S for most of their lineup. The P90D is about 1% better perhaps due to the active spoiler. No explanation why the X 90D is 4+% lower than everything else.

Still, the effective range does appear to be their stated range. My 90% of 228 equates to 253 RM, and that's after just 5k miles of driving. I'm not sure how to explain it, though.

Actually there are only three variants in this list. We all know the 60D is just a software limited 75D, so they are just the same variant except software limited. X 70D never existed. So really the list should be:
Model X 60D/75D vs Model S 60D/75D: 92% (the significant figure is affected by rounding, 0.2% is half a mile)
Model X 90D vs Model S 90D: 87%
Model X P90D vs Model S P90D: 93%

I'm at ~1600 miles on the odometer on my X90D. My 90% was 233 for the first month, then last week bumped up to 234. My 100% is 260, IIRC (two of them last week), possibly 261. I'm doing another 100% charge tonight, so I'll pay more attention.
How can the rated range on a certain percentage charge limit ever go up? I understand that the car should get more efficient as the tires break in, but that would affect actual range, not rated. Unless it was the .150 update that changed how it's measuring (or assumes a slightly better rated efficiency).

I agree it's weird that the X/S range ratio is so different for the 90D as compared with the ratio for 75D and P90D, but let's not be so quick to blame the X. Remember, it takes two to make a ratio; what if the S 90D range is the one that doesn't make sense?
How could we decide whether it's the X or the S that's throwing off the ratio? One way is to compare them independently on some dimension that ought to be an invariant. As an example, let's take the EPA-rated range and multiply it by the EPA-rated wall-plug consumption. This gives the amount of energy you'd draw from the wall to fully recharge, so it's related to battery capacity.
You'll notice it's actually higher than the battery capacity due to power conversion and charging losses. Nevertheless, it seems reasonable to expect that this number should be similar among all 75kWh models, as well as similar among all 90kWh models.
S 75D: 0.33kWh/mi x 259mi = 85.5kWh
X 75D: 0.36kWh/mi x 238mi = 85.7kWh
S 90D: 0.33kWh/mi x 294mi = 97.0kWh <-- interesting...
X 90D: 0.37kWh/mi x 257mi = 95.1kWh
S P90D: 0.35kWh/mi x 270mi = 94.5kWh
X P90D: 0.38kWh/mi x 250mi = 95.0kWh

The EPA kw per 100 mi has never correlated to the rated wh/mi on the car itself. I think those numbers are somehow extrapolated using gasoline = 33.6 kwh and the MPGe.
Ha. Yes they can. The S70D had an EPA of 244 or 245 (242.8 city and 246.4 highway) and Tesla downgraded it to 240. That apparently is an option. Presumably going the other way is not.
