AWD or 4 HI in Snow?

[brian2sun]

So the button on the 4WD selector can be pushed while driving when in 2WD Hi and you have 4WD HI for all road surfaces? What does the rocker switch on the dash panel do? Lock the center dif??

See my write-up below..

This thread is dangerously close to running away into one of those never ending AWD description pages.

There are almost a infinite variations on AWD, hell the word has almost no set meaning. Car designers throw around terms at will to sell cars. What is AWD on one car is called Multi-mode full wheel traction on another.

That's why I made this thread..

D'OH, I should have searched! Wasn't thinking about it before though....

There are big differences in the AWD systems Subaru uses as well, the manual cars have the 50/50 symetrical system, which is excellent. My wife's Legacy 2.5i auto (and other non-turbo vehicles) uses a Haldex system with e-center diff and open front/rear diffs, and it's just OK. Pretty well the same system used in the AWD Fords, and many other AWD vehicles, it's 90/10 front/rear under normal conditions, with the ability to shift to 50/50 under certain limited conditions. Then there's the higher level AWD used in the Legacy GT auto, and other models (pretty well the turbo models), which is a 60/40 split, and often with an LSD rear diff, this is also a pretty darn good AWD setup.

I find the multimode AWD in my truck to be good for normal-moderated winter driving conditions, far better than only have the option of being in 2wd or 4hi.

Yup, just like Audi and the several AWD systems. Haldex for example is the one used exclusively for the TT (Of course in the VW R32 as well)..
