all the A4 platforms use quattro since its a longitudinal engine.

So all the a4's use electronic differential lock with Torsen center differential and 50/50 split to the axis ???

i think it's the TT's that first started to use them..


but quattro is purely mechanical. not electronic at all

Any Audi/VW cars that use a transverse motor would use the haldex system.

Any Audi/VW cars that use a longitudinal motor would use the torsen diff.


Haldex:
A3
S3
TT
R32


Torsen:
Passat
A4/A6/A8
S4/S6/S8

"quattro IV" is simply the forth version of the quattro drivetrain.

This version employs the normal Torsen torque sensing center differential but, also uses front and rear electronic differential locks (EDL).

The Nissan Skyline GT-R uses a completly different drivetrain.

The Skyline uses the ATTESA E-TS Electronic Torque Split 4WD System. This is an electronically controlled system that uses sensors to detect wheel spin and make torque bias ratio changes as needed. It can run a 50/50 split or as much as 100% to the rear wheels if needed. This is much more like the Haldex system.
