Re: Permanent 4 wheel drive
VW Golf 4x4 and similar, S3, RS3 = VW 4motion Haldex
Audi A4, A6, A8, all S and RS incarnations, and all 4motion VW's that arent Golf or Jetta = Quattro Torsen
The badge is shuffled according to marque, not the tech underneeth
I have an RS2 which is the older Torsen (Gen 2) system. I've also access to an S3 3.2 Quattro. Both cars are amazing to drive and Audi can wring every horse out of those engines, and MTM can squeeze a little more on top. Both drive superbly but there is a noticable, marked difference when you push the cars. The Haldex gets out of shape faster, BUT the S2 lets go in more spectacular ways. The S3 merlely landed me in the track gravel runs. The S2 went backwards, engine said "bugger this" as everything tried to get traction to at least one wheel whith grip, at this point, going backwards at about 60, it gave up and I steamed off the track backwards with no power assisted anything.
The S2 has however, laughed as the last heavy snowfalls with decent tires (Sottozero)
The A3 really is, in all carnations, a glorified Golf and in some cases the Golf is a better bet.
FWD 3.2 V6 A3/S3 is pant wettingly scary on anything than a flat, dry, perfectly smooth road. There wernt many to start and very few left.
