Looking at your runs from 12 Oct 2018 summarized in the G01 ¼ Mile Thread,
https://x3.xbimmers.com/forums/showthread.php?t=1397744 , they essentially superimpose on emyoo’s just above the 400 HP sim curve, so about 55+/- crank HP higher than the stock G01 at 355. He had 12.32s/110.45mph 6 Sep 2018 with his JB4 Map5 at DA +886, and you were 12.38s/110.02mph at DA-123. Remember the sim is an approximated construct so wouldn’t view it as gospel. I'll post an updated graph in that thread to keep this one focused on the X3M.

That’s certainly a thought, 5against8. As the data chart is already complex with a lot of columns I felt it best to keep it manageable without getting into the handling aspects such as braking and skidpad. But a separate chart looking at some of those parameters would be interesting, and then somehow combining it with the P-SAVIE perhaps.

The X3M’s hypothetical weight came from a discussion last year in beammeupscottie’s thread,
https://x3.xbimmers.com/forums/showthread.php?t=1434391. MN2///M suggested BMW will attempt to maximize weight savings in the M variant, thereby coming in less than the G01. But it’s possible this won’t happen and the M will arrive more in the weight range you suggest. If that occurs, then it seems BMW should seriously consider 500 HP as the base minimum to remain competitive.
