There were numerous changes...off the top of my head:
- Heat pump
- Powered trunk
- Double paned front windows
- Heated steering wheel on LR and P trims
- Larger 82 kWh battery on LR and P trims (previous 78 kWh)
- New 2170L battery cells instead of 2170C cells on LR and P trims
- New headlights
- New trunk gasket for better water runoff
- USB-C instead of USB-A ports
- New accent leather stitching on center console
- Black exterior trim instead of chrome
- USB drive included in glove box
- New aero covers
- Completely redesigned center console and charging pad
- Metal scrolling wheels
- Magnetic sun visor clips
- New door insert trim
I'm sure there are others I'm missing also.
