For those can not stand new car smell. There is a tip that take advantage of EV :Window closed, set AC at HI + recirculation and max fan speed for 30-40 min, turn on seat heating if you want. Then turn off heat ,fresh air and keep fan speed max for 20 min to vent out air.
This can increase the speed of off gassing, especially now is winter ,not have too many hot sunny days.
