I found the source from where I got the information.
This is an interview between Mark Templin, General Manager of Lexus USA and Kevin Watts Editor from Lexus Enthusiast:
And then we have this speculation whether the ES should be manufactured in the US or not:
From this source: http://minkara.carview.co.jp/userid/...blog/27120510/
We find that the ES300h might replace the HS250h as it has been done in the US (that's from what I can understand using Google translate)
Maybe because of the introduction of the right-hand-drive ES in other markets? Since Europe is not getting it but what about Japan?... We might see it in South East Asia and Australia.
Now regarding the new LS... here are some more insights:
The new LS design will be quite different than the previous one featuring new equipment. Pricing will be pretty much the same as the current LS (as we have seen with the new GS).
However, fuel economy has not been improved (LS460), hybrid batteries have no been changed, trunk space has not been changed as well, and the wheelbase is the same one as the current LS. Handling and driving dynamics have been improved.
Exterior colors from the new GS will be aded to the new LS and so as the exclusive F Sport colors.
It seems that this LS is not a complete model change but a major refresh
Here are some features of the F Sport package
