My wife recently bought a 22' F-Pace SVR. I was doing some reading on that forum and someone had posted an explanation of how the transfer case worked. They said in normal mode it split torque 70% to the rear & 30% to the front, Dynamic mode was 90% to the rear & 10% to the front, and Snow/Rain was 50/50. From what I understand, the F-Pace SVR and F-Type R has the same drivetrain except the F-Pace has the project 13 torque converter. Does this sound right?

 

My understanding of the F-Type AWD is that it's 100% rear until there is slippage, then it goes up to something like 50/50 as needed. Full disclosure: I've got RWD and no torque converter so am hardly an authority on either.

 

The transfer case is the XE is pretty simple, and I think it allows a maximum of 50% of the torque to be sent to the front. I imagine the F-type has a heavier-duty version of this. Don’t know what the F-Pace might use.

Here's a little more on the AWD and IDD. Although not dated, this article claims that AWD with IDD is on the F-TYPE, XE, XF, and the F-PACE. It does confirm what lizzardo said, that normally 90% of the torque is applied to the rear.

Reading between the lines, my take is that the "Adaptive Surface Response" feature described here is automatic for the XE and XF, and perhaps what occurs with the F-TYPE when switched to Rain/Ice/Snow mode. The F-PACE, apparently, has an additional mode for deep snow... perhaps that what the Torque Converter supplies.

FWIW, I flipped on the RIS switch the other day, coming home on a icy evening. The Owner's Representative noted how she preferred it, as it reminded her of the way her Audi feels.

 

Good info. Thanks for the post.
