Hello all. I'm new here but may be able to shed some small insight into this particular question. I went in, about a month ago, to visit my local LR Dealer and look at the LR4s. At the time they had brochures and website information reflective of the three models of LR4 for 2016; the LR4 Base, LR4 HSE, and LR4 HSE LUX.
After some thought and discussion with the wife I went back last week to order my LR4. The salesman greeted me and explained that I had good timing as the 2016 LR4 was now referred to as the 2016.5 Model in internal Land Rover communications. The HSE and HSE LUX were replaced with the HSE Silver and HSE Landmark, respectively.
The HSE Silver includes some upgrades in the software of the infotainment system, the HD/Sirus Radio, the InControl Apps, the Vision Assist Package, the upgraded 17 speaker Meridian sound system, and a rumor of different HSE Silver Edition tailgate badging.
The Landmark Edition added Bright Silver roof rails, Landmark badging, and some custom colors in addition to all the perks of the HSE Silver and typical HSE LUX.
The intention, as the previous post indicates, is to clear inventory of products which will be of little use once the LR4/Discovery 4 reaches its End of Production. I opted for the HSE Silver. Originally I had intended to purchase the HSE and spec' out a model with nice options within my budget. With the HSE Silver however I wound up being only about $500 over my HSE total and yet with every single option available.
They even replaced the 2016 LR4 brochure with a slightly smaller reprint for a 2016.5 model. (The brochure still says 2016, not 2016.5, but the salesman assured me that internally they are making the writing on the wall pretty plain that the LR4/Discovery 4 platform is done in a matter of months. Notably enough hey have a new LR4 Kit brochure with a list of available options and the Warn Winch made a return which was absent as an avilable option in 2014-2016 publications. I'm hopeful I can get a small discount on the pricing on some of the after factory kit options I'm looking to add but we'll see.
He was pretty excited about emerging Land Rover models and technology but also agreed that the loss of the Defender and LR4/Disco 4 represented the literal "end of an era" for Land Rover and the LR4 was the last "...true to its roots Land Rover in North America."
I should be taking delivery in early May and am pretty excited. I have a poor quality copy of a few pages of the internal document that he showed and if you were interested I could send you a copy.
