The E93 could be ordered with a factory installed LSD dispenser, by which it's driver could take hits of LSD without removing his/her hands from the steering wheel.

Due to cost cutting measures this optional feature was removed from the 2010 E70 models.

The option will be brought back in 2011, in an attempt to convince drivers that their new X5's are actually nice to look at, when compared to the 2010 models.
