It seems that the front part of the suspension and chassis came from the GS, the midsection from the IS C and the rear parts are from the 3 IS. How that can be efficient, I have no idea, but clearly Toyota knows more than I do.

I can't help but wonder if a different platform configuration (all or mostly based on IS or GS), might have made this car lighter? Piecing together parts from three platforms and then welding/reinforcing them together can't be light.

Or perhaps thats the 3 best sections of each car

This is what I found about the RC at Car and Driver:

Source: Car & Driver

From this, I gather that the RC sits on a strengthened IS C floor pan (shortened IS pan?), with a front end structure (frame rail extension, engine mounts and suspension) from the GS, and rear suspension from the IS.

If the 3IS was not designed for a V8 engine but the 4GS was, it makes sense that the RC (and RC F) uses the GS front end.

No, they won't be cutting and re-welding together IS floor pans to make the RC. The "cutting and re-welding" would have been done in the design software. The IS C is derived from the IS and the IS is derived from the GS so it is all related and all fits together.

So now that we will have the LSF, will there be still be a need for the LS600h? If so, which one will be pricier one and is there any word on how the LSF will be priced?

This 3.5L V6 hybrid system with 500hp and AWD should be an optional powertrain choice but I dunno if they'd keep the LS600hL moniker

From what we've heard around the rumor mill:

LS500 (5.0L V8) 467hp*
LSh (3.5L V6 Hybrid) 500hp*
LS F (TT5.0L V8) 600+hp*
