I've picked up my new 2018 Premium few days ago, and just found that there is NO liner there for the rear seat cup holders. But my 2017 Prime has that. Is the dealer missing that? or it is removed from the 2018 model? Also, one thing I noticed the difference between 2017 and 2018 is the MPG shown in the EV monitor, when in EV mode, instead of 199.9, now it shows 999.9
Don't know about the cup holder liner, but I know the MPG display for 2018 was changed to 999.9. There was a thread on that. 2017s vs 2018s Max MPG display differences | PriusChat
