Here's a lengthy video comparing lots of different makes and models, and how they perform on rollers. The Volvos really shine.

The Volvos really shine in this long video comparing many different AWD and Traction Control systems.

Just found out the 1997 AWD 850 (not sold in the US), and the 1998-2000 V70XC have Eaton rear locking differentials. All these models have the VC AWD systems. This locking diff is more effective than the ABS based traction control (with open diffs) on the more recent model Volvos.

Volvo calls Haldex 3 & 4 Instant Traction, because it will activate the rear wheels with just 15 degrees (1/24th) of a front wheel spin. And it sends 60 ft-lbs of pre-charged torque to the rear wheels instantaneously. This is an improvement over Haldex 2 which will send torque more gradually to the rear wheels after 1/7th (51 degrees) of a front wheel spin.

disconnect unit

The 'disconnect' unit is a 'freewheel':

And the 2006 XC90 went to Haldex 3rd gen also. 4th gen in 2009.

Mazda 323 GT Turbo 4WD

You forgot the Mazda 323 1.6 GT Turbo 4WD! (and/or 1.8 GTX)

We are again on a full-time AWD System with planetary gear center differential to split engine torque, electrically lockable via a button on the console that would have activated a Viscous Coupling unit.

Before 1990:
- Normal torque split 50/50
- 185/60R14 performance tires on 5.5J-14 alloy wheels

From 1990:
- Normal torque split of 43/57 (for a rear-wheel-drive feel) could be varied to 60/40
-195 / 60R-14 performance tires
