Am I the only X5M owner not impressed by lack of power???

[TTBear]

I was under the impression that pressing the "M" button made no difference to your acceleration, but rather, simply accentuated the throttle response??

I think that if you floor the car in "M" mode, it will feel faster, but actual acceleration times will be the same, no???

That's how it works in the M3, anyway...

The M button also delivers more power from the engine, similar to the power button on the M5. It depends how you set the m button in the idrive of course. It also stiffens the suspension and allows the car to drift a bit if you push it.

No, actually.

It is true that the power button changes power settings from 400 to full (507) hp in the BMW M5, but this is NOT the case with the X5M or X6M.

I quote from the Supplementary Owner's Manual:

M Engine dynamics control/POWER
With M Engine Dynamic Control you can influence how sporty the reaction of your vehicle to accelerator pedal movements is to be. Two programs are available to you.

The "Efficient" program is activated after each engine start.

"Efficient program
In the "Efficient" program, a lower fuel consumption is achieved. The engine and the M Sport Automatic transmission respond to accelerator pedal movements with an emphasis on comfort, which is ideal in city traffic or in snow, for example.

"Sport" program
The "Sport" program permits the engine and the M Sport Automatic transmission to respond more spontaneously to accelerator pedal movements. The acoustics of your BMW X5M/BMW X6M become more sporty.

There is NO mention of increasing any horsepower. The accelerator pedal simply becomes more "sensitive" to smaller increments of pedal movement - as it was with the e46 M3, and as it is with the e9X M3. The throttle sensitivity changes - NOT the amount of power that is made available.

I tried a few 40mph to 100mph runs (closed circuit of course ) using both modes. Times were all virtually identical.

Yes you are/that is correct. No additional power from the 'M' button on the X5/X6.
