Last time I checked, the new 740i weighs 2130kg and 760i weighs 2310kg. These are exact same weight as the LS500 and LS500h. The X5 50e now weighs 2570kg, almost as much as LX. So it turned out weight isn't a real problem for GA-L in the long run anyway.
LF-1 should never have been cancelled. In fact I have no problem with them retiring the LS name and replace it with LF-1 instead. All that built-in rigidity to handle a V8TT engine would help with ride comfort and have plenty of spare GVM to add even more insulation. 2300kg for a base V35 and up to 2700kg for a V8 PHV should all be well within spec of the overengineered platform, and these are not considered "heavy" nowadays.
Instead, the GA-K platform is now pushed to the absolute limit. The Century SUV weighs 2570kg and LM500h weighs 2500kg. That's growing from a platform targeting vehicles in the 1500-2000kg range. I doubt at such different stress levels, the "big GA-K" actually shares enough components with the regular GA-K to be that cheap to develop and build.
Well from what I'm hearing, TNGA-L is supposed getting heavy revisions to be lighter and more space efficient. If this ends up being true, then I think the poor guys have heard our cries pretty loud and clear.
If the new TNGA-L platform is executed correctly, perhaps that will encourage them to develop RWD crossovers.
