The XF is a medium large executive car in a 4 door, 4 door long wheel base (China) and estate (sportbrake, see above) configurations. Something like 375,000 have been sold since 2008, with 42,000 finding new homes in 2017.
The point of note in 2017 is how well the XF L (see pics below) is selling in China. The figure below is for cars made in China. If any XFs are imported, they are not included in that figure. However, looking at the 'Others' total at the base of the chart would indicate few if any are brought in.
So China now accounts for 50% of all XF sales globally. There is no other vehicle in the range of JLR vehicles that have that sort of percentage for one market. The fact that China took 23.9% of all Jaguar sales in 2017 shows that it doesn't have that sort of share for other models.
All of the data is sourced from numerous places and nothing was provided by Jaguar itself. I know of no car manufacturer that would reveal this sort of information. The fact that competitors already know it anyway leads me to the conclusion that the reason it isn't openly available is companies don't want people like me interpreting it. All I can say is it's good publicity.
