You realize of course that regenerative braking puts more* back into the batteries for heavier vehicles only because a lot more was necessary to speed them up in the first place?

I do realize that regenerative breaking does not 100% cancel out the energy required to accelerate the vehicle.
The Model X will be ~10% heavier and Musk has stated recently that the range is expected to be ~10% less than that of the Model S.
In other words, obviously a heavier vehicle will use more power than a lighter vehicle, that's true with any fuel source, but it's a small difference in this case. They could put a battery pack with 15% more capacity in it and the range would be about the same as the Model S, but they're probably going to use the same battery as the Model S for compatibility and manufacturing reasons.
