The N54 [Twin-Turbo] will be replaced by the N55 [SINGLE Twin-Power TURBO] because of the fuel saving it is capable of.
The new series of High-Revving Turbo 4 Bangers, most likely will see the same Twin-Power Single Turbo application.
The 2011 X3 being built on the up and coming 2012 3er Platform, may indeed see the first application of the new N55 Motor.

The N55 will be in the 5er GT, The X5 and the X3.

Semantics? You decide.

It is not a variable vane. It is two chambered.
