WHY?
I thought it might be the clutch could not take the extra torque, ( as in the V70 AWD R the auto box was torque reduced IIRC in 1st and 2nd) but I see that the Polestar option is available for manual cars which .... you've guessed increases the torque of the manual cars???
So now I'm back to square one - Why does Volvo de tune the manual??

It could be just a marketing or emission " thing" unlike the C30 D5 which took the 185 bhp D5244T4 but reduced it's power to 180 bhp for "cooling " reasons , but a couple of years later they offered a polestar conversion ! The C30/V50/S40 range has a smaller radiator and intercooler to the big cars ..
