There is so much to tell, I will mention only a few key points for the each field.

Software: self driving capabilities (i.e. autopilot), FSD (Full Self Driving) beta, shadow-mode neural net testing, OTA (Over The Air) updates, games and entertaiment, Autobidder energy trading platform, etc. Battery: tabless design, dry electrode, new 4680 form-factor, nickel instead of cobalt, manufacturing and cost improvements, etc. Electronics: efficient motors and inverters, custom ASIC chip for FSD computer, Dojo supercomputer, etc. Mechanical engineering: "octovalve" thermal management, structural battery pack without modules, "mega casting" aluminium body design, etc.

Edit: forgot to mention supercharger network.
