2004-2005 AP2
- They are all fundamentally AP1's with AP2 facelift and suspension, they share everything else the same as AP1's
- They run the same F20C and ecu as the AP1's, that's why they don't have VSA

2006+ AP2
- They are all fundamentally AP2's, they share everything the same as other international AP2's (including gearbox, tranny, etc) but without the F22C engine
- They run a slightly different F20C and an AP2 ecu, that's why they have VSA
- The main difference between the F20C in the AP1 and AP2, is that the the AP2 F20C has the DBW cable, the IAT on the intake arm instead of throttle body and all of the other things it needs to be able to run the AP2 ecu (fundamentally having all AP2 core engine components excluding the F22C engine)

To say the AUDM AP2 is just a facelifted AP1 is only true for the 2004-2005 models but not for the 2006+ models
