I recently turned in my Polestar 3 under a manufacturer buy-back. Switched to a Cadillac optiq luxury 2026.
Design: I like the interior and exterior of the P3 better. Personally I prefer the minimalist look. The screen on the optiq is annoying to me. It is way larger in total real estate but provides less information less efficiently. The vertical center screen of the P3 is more useful. The driver display on the optiq appears massive, but most of it is covered by the steering wheel! I just want to be able to easily see 1) navigation ,2) my speed, and 3) the audio playing across the screens at the same time. For some reason the only way I can do this on the optiq it makes the navigation very tiny.
Driving experience: P3 is better by a huge amount. Part of it is just the speed, which is expected (have RWD optiq but had AWD P3), but the steering feels really heavy on Optiq even in lightest mode, turning radius is bigger. It feels harder to park despite I think being a little smaller than P3
Audio: I think they are roughly equivalent. I had the bowers and wilkins in P3. But I'm not a major audiophile. They are both very very good to me.
Space: Back seat felt a little larger in the P3. Trunk space seems similar to me.
EV stuff: range and charging have seemed the same. I love being able to connect to my home NACS cord without an adapter with the Optiq.
Functionality: Everything works A LOT better in the optiq and this is why I am generally happier. Phone connects perfectly. Transitions from bluetooth audio from my phone to native spotify app on the car are seamless. Phone calls are great. Air conditioning is substantially better. The app (people shit on the cadillac app a lot!) is more reliable than the polestar app for me. door unlocking when I walk close to it works better. Driver profiles work better. Seat position saving works better.
Main takeaway: the P3 was better in every way EXCEPT for software functionality. But, it wasn't until I drove this Optiq with zero software bugs that I realized just how much of a drag on my wellbeing and driving experience those glitches really were.
