There are also some additional changes... Some of them I found myself reading on the net and for some I was pointed by distributor:
1. Servotronic is now BMW generation II
2. Automatic gearbox is now Generation II - much faster with better mechanics and (much) modified sw. It's 6 speed instead of 5 (if apply to your model)
3. Automatic gearbox on 3.0SD is generation III (or IIa) and is 25% faster than on generation II (50% faster than on generation I). Diler mentioned that sw when gear is in SD mode learns drivers habits of driving... although this is not user visible...
4. Brake Assistance Managment is completelly new and includes emergency braking - when you moove your leg from the trhottle fast and apply strong pressure on the break pedal it wipes brake disks and apply stronger pressure....
5. XDrive is now Generation II with numerous improvement and updates to Generation I. Accelerometers arround the vehicle measuring latteral acceleration on all 4 sides of the X3 and in the center gravity are new and much more sensitive. Gyroscopic system is new.... Electronically Driven Cluthes are new and have 3 times faster response and can susain double pressure than previous...
X3 is the first BMW with Xdrive generation II implemented. It will also be introduced on series 3 and series 5 XD cars in 2007...
6. Suspension system implemented is new. X3 is now more comfortable than before without sacrifising lateral stability...
Basically the biggest and the most important upgrades in X3 are in XDRIVE. and in NEW suspension system and unfortunatelly this is not recognized by magazines and even not by users...
My diler mentioned that complete Vehicle Managment Systems computer is new generation, new processor. It is more complex and new training was requested for maintenance technicians. The SW is now 4 times the previous one (in size)....
It will be interesting if we have some BMW service technician on board, authorized/trained for old X3 and facelift to give us some more insights and proof if I was informed properlly...

Alex
