I had it done on my 2017MY V60 diesel hybrid, but don't think it did anything to the AWD.
However, that maybe because the RWD is from the battery ISG rather than a Haldex?

On saying that, I can definitely get the back end to swing out if you floor the accelerator with a bit of steering lock in Power mode, and all 470 lb/ft is deployed at once. Safe but unexpected !

Thanks, and as suspected, it doesn't work on my previous-gen V60CC. I presume it's down to not having different driving modes like 'dynamic' so there's nothing in the ECU that can be reprogrammed, and probably the Haldex diff isn't electronically controlled so can't be tweaked. Or something.

Useful press release.

It says about the hybrids being read-biased already because of the battery power only to the rear axle. Logically that sounds the same for the previous gen V60 hybrid, as it drives more weighty at the back end.
