If the new sport seats are like they were on the 1 series and E90, then yes, the side bolsters will be powered, as they use an air bladder to pump them up so they need a motor. Also, the lumbar should be powered as well. Probably runs off the same motor for the air.

BTW, the side bolsters are along your sides, not really your back.
The lumbar will be at your lower back and adjust to about almost mid back depending on how tall you are.
