Skyline GT-R R33 (1995-1998 *plz Confirm*)

Mechanical rear wheel drive with a clutch to transfer power to the front differential. Torque-vectoring rear differential.

"The clever electronic control system is fed by all the information ... such as G-force, boost pressure, throttle position etc, in addition, the speed of individual wheels measured by ABS wheel speed sensors. By these information, the computer knows whether the car is running out of cornering limit or not. If not yet, the multi-plate clutches won't intervene, thus the car can power slide through the corner smoothly. In case out of limit, the multi-plate clutch will engage and send torque to front wheels, increasing traction."

X-Trail

All Mode selectable all wheel drive system - normally front

wheel drive vehicle, in AUTO mode rear axle engages when front wheels start to slip, power is variably distributed from 100:0 to 50:50 front to rear. In AUTO mode the system works as an automatic all wheel drive system.

In 2WD mode, the clutch is unlocked permanently. However, even when in 2WD mode, front wheels can sometimes be engaged by electronic control unit, for example under heavy acceleration.

In LOCK mode the tranfer clutch is permanently locked - power distribution 50:50. If vehicle speed increases, the vehicle automatically goes to AUTO mode, then, when speed decreases, it switches back to LOCK. When transfer clutch oil is overheated, the vehicle goes into 2WD mode.

X-Trail, third paragraph:
"In 2WD mode, the clutch is unlocked permanently. However, even when in 2WD mode, front wheels can sometimes be engaged by electronic control unit, for example under heavy acceleration."
Should read "... rear wheels can sometimes be engaged ..."

I would also suggest that this feature may be nothing more than an unintended artifact of the multi-disk clutch mechanical design. Residual drag of the control clutch (at zero control current) may be enough to actuate the main clutch (via cam plate) if the speed difference is high enough.

Re: Missing system...

The Skyline is conceptually the same.
Mechanical rear wheel drive, with a clutch to transfer power to the front differential.

I forgot the best part, the Skyline had a torque vectoring rear differential.
