2009 BMW 750i: Rump shaker

July 23, 2009

Trying to stay alert during that long haul to Monterrey? Or did you just have a particularly killer Pilates workout that left your glutes sore?

Perhaps you may be interested in a seat feature that BMW offers. Our long-term BMW 750 has the Active driver seat equipped with butt massage.

The driver's bottom seat cushion has a massage function activated with a door mounted switch to the far right, opposite of the Gentleman function switch.

The sensation is similar to that of a seat's lumbar support, but instead pressing on your booty. But it's a smaller lump than a lumbar, and feels about the size of a racquetball or perhaps a golf ball.

There's no vibation, just the lump that intrudes up into your right cheek, deflates, the feels as if it moves to the left cheek, then deflates. The lump seems to move in a somewhat circular path beneath your tuches, but there is more than one lump.

BMW's website states "Active seats are also available whereby the seat bottom moving up and down intermittently to mobilise (sic) the occupant's muscles around the hips and lumbar spine to prevent any feeling of cramp or fatigue."

Check out this lame video of the rump shaker in action.

I tried the rump massage for a couple of minutes, became annoyed, then turned it off.

I suppose you could use it to keep you alert during a long trip. Or if you were bored.

PS: I'm anticipating that some of you may use the trite term "happy ending" in your comments. Try something original, OK?
