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 !

This maybe of interest, and answer a few of your questions!

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.

I hope you considered a transmission oil change to go with all that extra torque.

No, it's a Volvo upgrade and the car itself is under a Volvo warranty.

It's not really a car that you either need or want to thrash much, but it's a worthwhile boost over standard.

Default Rica and Polestar tuning

I had the RICA on a S80 D5 (185 bhp) and the polestar on a V90 D5 (235 bhp). Although the RICA was on the paper increasing power more than the Polestar, the effect of the Polestar on the drivetrain settings (gearbox, AWD) was a completely different game. It felt like the RICA increased just turbo boost, the car was “going more”, but it made turbo lag more evident. The Polestar was simply impressive, the car was driving differently. Add that it was difficult (two big insurance companies said no) and eventually expensive (premium more than doubled) to insure the car after the RICA tuning, while the Polestar tuning did non increase the cost of the insurance, and to me it is a no brainer: the Polestar tuning may cost more upfront, but in the long term is more cost effective and more fun. Despite both promising improved MPG, in reality MPG did not change in normal use, and was significantly worse if the extra power was used. I am no expert, but extra bhp and better MPG seem to good to be true…
I am, however, unsure whether the Polestar tuning will affect your drivetrain settings or simply the engine- I think the drivetrain is affected from 2018. Worth checking before deciding.
