Kolikor je meni znano so prejšnji awd-ji pri Volvotu bili zasnovani na osnovi viskozne sklopke(princip je podoben haldex pogonu),a je precej manj odziven od sistema s haldex sklopko. Del članka iz leta 2002, xc90:
By comparison with the earlier Volvo all-wheel drive systems based on a viscous coupling differential, the new AWD system is much more swift in its response. One of the front wheels need only start to slip through a seventh of a single wheel revolution for the system to divert more power to the rear wheels. This means that the new AWD system provides much better starting traction on difficult surfaces, minimising the risk, for instance, of the front wheels digging themselves into soft sand. The ‘heavier’ the driving surface is, e.g. wet sand or mud, the greater the difference and the advantages compared with the earlier system.
Še en izsek iz tega, kaj je bilo novega leta 2001:
The all-wheel drive version of the successful S60 was launched: the Volvo S60 AWD. Central to this electronically-controlled hydraulic system is the Haldex AWD coupling.
Torej očitnota so haldex sistem vpeljali že leta 2001 v S60, mogoče da so malo preverili zanesljivost. Nisem pa prepričan kakšen pogon ima V70XC(gen. II.) v letih 2000 in 2001.
Ja kot smo ugotovili ima tvoj V70AWD žal še visko sklopko za zadnji pogon (se pravi to velja kar za vse Volvote, ki nimajo gumbka za STC/DSTC).
Kupil sem Volvo V70 letnik 2003 AWD, Geartronic menjalnik.
