I was just reading about the upcoming BMW X6, and it turns out that the new XDrive AWD system will feature a dynamic torque apportioning system that shifts power between the rear wheels. And yes, it over-rotates the outer rear wheels in turns. Heck, they even copied the MID SH-AWD readout.
While this system will make its debut over the summer in the X6, it will trickle down to the rest of the line in the 2009 model year.

It's too bad that the X6, after all this new dynamic stuff was promised, is turning out to be barely more than a restyled X5.
It would be interesting, though, to see what SHAWD would do if it wasn't so FWD biased. The torque steer (what little there is, honestly) is a bit annoying. |

Yup, the way it's shaping up, the X6 will be to the X5 what the CLS is to the E-Class; swoopier, less practical styling, more $$$. And like the CLS, it's strictly a four-seater.
That said, the new XDrive will be biased towards rwd handling characteristics, which certainly works in its favor. Mind you, I have yet to experience any torque steer, but then I'm not doing Don Garlits' impressions at stoplights either (I'm more into the 70mph->90mph thing).

| I just read about the new system in the X-6 and BMW made a point about the difference between SH-AWD and their new system(DPC). Where SH-AWD is activated during throttle response only, BMW's DPC can be activated during off throttle and throttle response. --Matt |

I noticed that as well. Apparently it uses clutches to keep the system on tap when the throttle isn't being applied, and bases its responses on yaw, as opposed to wheelspin.
Regardless of what the end product winds up looking like, there's little doubt that it's going to handle like a proper BMW.

| What's the value in torque distribution of BMW's DPC in "off throttle" situations?:confused: |
