OTA update to 2.5 was due sometime this month last I heard.
Performance Package for DM Polestars is available in the US from what I've seen. Don't know about NZ owners. An extra 68?hp, as if the DM really needs more.
ETA: We had a software issue addressed in AKL a couple of months back and received a DM as a loaner for a couple of days. Suffice to say my suspicions of owning a DM being a licence risk factor proved founded. Didn't have any Popo interactions but the acceleration is certainly addictive and far too tempting.
My brother had the Performance Package installed at the dealers a few months ago so definitely available in NZ. Mainly impacts mid-range (80-140kmh) and quite noticable!! :-)
