Interior:
1) Materials, colors, and seats.
I posted my thoughts here. TLDR: different textures gives the interior luxury feel despite being all black and grey; the seats are soft and not prone to leather creases; rear cabin somewhat lacks luxury feel. Overall interior build quality is great and much better than my previous tenant's Model Y and loaner Model S (2019?) and original X. Partner also likes it over her fully loaded leather interior BWM X1. Compared to the other GT interiors, I consider the Alcantara PurLuxe to be just a very slight downgrade only because of the rear cabin.
I mentioned this elsewhere that I'm disappointed that the ambient lighting's color can't be changed. Touring and GT have the nice ceiling light strips. I understand that customers should get more for the increased prices, but no need to significantly downgrade and cheap out on inexpensive colored LED lighting. They have to be careful what they downgrade because it becomes questionable if the Pure are missing out on features that are available on much cheaper cars.
2) Buttons and interface. The volume adjuster in the middle is my favorite! Makes volume adjusting very easy especially since different tracks I enjoy more or less at various volume levels. I have not used the manual buttons for temperature and fan speed. Turn signals and drive modes (Park, Reverse, Drive...) and buttons on the steering wheel seem properly placed. The headlight and wiper controls are located on the left side of the dashboard touch screen. I like the push button on the left side for single windshield wipe.
3) Software and navigation. I. Effin. Dislike. Alexa! My old Pioneer headunit with Android Auto works better! Alexa is horrible at finding locations. I'd occasionally get very annoyed and yell at it! Other than that I haven't really had issues with the software. Charging has been fine and any issues on that regard has been on Electrify America's end. For music I use Tidal though searching for music has been a struggle.
AC (not fully tested) and Heating:
1) Heating and fan is not the best. I can confirm the common complaints that it is overall weak. It takes a while to heat the car.
2) Seat heating is fantastic! Level 1 heat (up to 3) provides sufficient heating. I have not really tried level 3 as I'll likely end up with a roast pork butt.
3) Steering wheel heating gets hot! Can't adjust so have to turn it off after a few minutes. Also a warm steering wheel somehow makes me sleepy.
Sound system and road noise:
My favorite part is not being able to identify where the sounds are coming from. I have a near $3k speaker system and a much more expensive headphones set-up at home. Being a basshead I currently have Bass at +4. I enjoy listening to music while charging or while just parked somewhere. Lucid sound system overall sounds clean and detailed, just missing a bit of that bass depth that a bigger subwoofer would provide. The quietness inside the car helps too since road noise can easily drown out the small details from music in poorly insulated cars. The Pure blocks out a lot of outside noise. When driving at high speeds though, I can hear some wind noise on the left side. Seems to be coming from the side mirror area.
