So we hear that 'proper' Audi's ( N/S engine ones anyway) have the Torsen 4 WD system, most current VW's and Skoda's have the Haldex system, and Subaru have a viscous coupling? That right?
And in terms of actual 4 WD performance which are 'best'? As far as I understand it the Torsen are genuine fulltime 4 WD, while the Haldex systems are typically front WD till something slips then the rear wheels kick in, and Subaru claim their system provides drive to all 4 wheels all the time? Doe sthat make the Subaru's 'better' than the Haldex system?
My interest is in establsihing the 4 WD capability of say the Superb/Octavia 4 WD's and new Passat 4Motion against the Subaru Legacy/Outback....so which is the real deal?
Thanks in anticipation.
