The Haldex is strictly a performance enhancement. There were no
reliability issues with the viscous coupling. In fact it is one of the
most reliable systems in existance since there are no valves or switches
to go bad. It has a long history of reliability. The Haldex system is
newer and unproven.
Haldex historically made automatic brake adjustors. It has expanded
into other hydraulic fields, but the Haldex AWD system is a new field
for it and is relatively unproven.
