X5M/X6M: 553 lb-ft. 1800-5860 rpm.
X5MC/X6MC: 553 lb-ft 1800-5890 rpm.

X5 M50i: 553 lb-ft. 1800-4800 rpm.

So, they all have the same max torque and low rev performance should be the same(till 4800rpm).

Once above 4800rpm, the M models are much more performant.

This would also feel M models to feel slower in the low revs, but in reality this is not the case.

On the other hand, X3M and X3 M40i have completely different torque curves, M40i max torque starting much lower(369 @1520rpm) and X3M 442@2600.

So no, the X5M will not have the same issue as the X3M does.
