The F85 X5 M is 4.1 seconds to 60 MPH and the X3 M40i is 4.6 seconds to 60. I can't see BMW putting out an X3 M that is faster than the X5 M until it is revised so I'm thinking we'll see the X3 M come in at around 4.2 to 4.3 seconds.

BMW Blog claimed twice that the X3 M will get the new S58 motor with 450 to 460 HP in these articlse back in March, 2017:

With the M40i at 355 HP and 369 lb-ft torque and the S55 at 425 HP and 406 ft-lb of torque, I think seeing an X3 M with 450 to 460 HP is optimistic.

BMW Blog later revised their estimate in an article from August 29th, dropping it to 425-430 HP; I think this is more realistic.

It would not surprise me if the X3 M ended up with the same base S55 motor in the current F8X or a tuned down S58 with a possible Competition Package a year or so later with slightly more HP as the F8x M3/4 and X5/6 M get revised.

Either way, it will be a beast of an SUV. I'll be real interested in seeing what price point it comes out at.
I'm crossing my fingers for 2019 X3M/X4M with S55, it'll be a first time for BMW to release S58 (new engine model) into X3M instead of M3/M4.
Maybe they'll do S55 first year release like they did with my X4 M40i (N55 revised) haha.
