Refresh brought LED headlights, next-gen leather seats, Bioweapon Defense Mode air filters for the Premium Upgrades Package, and the center console is a default option.
Additionally:
- All 75D have at least Autopilot 1 hardware.
- Post-19 October 2017 75Ds have AP2 (Enhanced Autopilot + Full Self Driving) hardware
- In the past few months, the next gen seats were replaced with newer premium seats
Battery, drivetrain, interior, etc. are all largely the same.
