All modern AWD systems, including 2002+ Range Rovers, use some variant of the system described here. Reasons are 1: government fuel economy requirements, it allows the system to open the clutch and run in 2WD the majority of the time. 2: it allows computer algorithms to adjust torque distribution based on sensed friction and engine torque demand, in advance of wheelslip. The Range Rover viscous coupling could only respond to wheelslip, and relatively significant wheelslip at that. 3: it allows the computer to override AWD activation to prevent interference with stability control braking, something now required by law.

Makes you realise how revolutionary and clever the Range Rover system was.
