New steering in XC60 MY 2011?

Dear community, for the new year 2011 of the XC 60 almost everything has been said, only not yet of everyone. In the XC 60 the NSW fall away in all equipment. That’s for sure (until now). The reason is called the new electrohydraulic steering, which needs more space.My question: Does anyone know what this steering does differently/better can do, that you sacrifice an important design element (NSW) for it? Or is it “just” due to the latest development in the “building kit” (should it be from the S60 s I have not found anything about it in the forum so far (yes, I used the search function!). I am curious, because some “intimate” connoisseurs and insiders are on the way in the forum. ld d-speed
