2016. Also, I just fitted the LR Hitch myself, $875 (incl shipping...gulp) but it does the job and you can fit any size wheel under there now.
I have the 2016 Discovery Sport with 3rd row... I am also looking for a hitch that will work and can't find one anywhere..(other than $3500 at Landover dealer). What was the model that worked for you?? Part number would help also PLEASE!!
