i believe the alpina engine is a derivative of the N54 rather than upgrade of the N55 now B58
No, it is/was a modified N55 with 2 turbo's.
N54 is, a far as I know, out of production. Alpina always needs to use engines which are currently in production with BMW.
Not sure if new model is based on N55 or B58. (Both engines still in production with curren (certain) BMW models.)
