Is 2500 RPM normal at 80 miles an hour in a 2016 nx. I can’t seem to get over 23 miles per gallon on the highway when I usually get at least 26 to 27 mpg.

 

I see you're in NY, our Chicago winters here make everything drop (not including gas prices). I would say you're pretty comparable to our NX hybrid, though the hybrid systems shines more with urban commuting and not the freeway.

 

Normal for me. I have never gotten over 21MPG hybrid style driving so unreal you are getting 26-27.
