Not surprising to see triple headlights appearing in facelifted IS as its competitors also have more exquisite, uniquely shaped premium headlights available. And to make triple LED headlights the standard across various Lexus vehicles, it also can reduce some cost due to use of common components and it increases visibility on the road.
Really look forward to see how Lexus change the bumper details to suit the new headlights.
If there is any changes in interior --- I would think the following makes sense as it has an improved premium feel, cost reduction by using common elements, etc.
1. Change the front overhead to LED with touch sensing, just like what is available in NX, new RX, ES, etc
2. Remote Touch controller is replaced with a remote pad. The positions of upholders, remote pad and the drive selector will be like what are in RC/RC-F.
