Next Lexus LS (2018 model)
Aluminum was used in the 2003-2010 5-series...aka the E60 (and the 2002-2009 E-class for that matter)...and this was before BMW decided chassis stiffness should be of paramount importance, which is why the F10 has a remarkably stiff structure. The weight does not indicate platform sharing, period. There's more to it than that, although it can be a contributing factor (as stated with the F10 an F01).
The IS is less than 200lbs heavier than the C-class and the GLC300 AWD is actually heavier than the NX200t AWD (as per Car and Driver, who weighs cars as-tested) yet the Lexus was dusted in both situations. The IS200t at least had the 8-speed auto.
If the 2003-10 E60 5 Series had NOT used an aluminium front section, it would have been heavier, but still only to the tune of about 210 lbs like the 1996-03 E39 5 Series vs 1998-05 E46 3 Series; current 2010-17 F10 5 Series is nearly 400 lbs heavier than current 2012-19 F30 3 Series; indicating that something is very very unrelated.
Small differences in weight indicate similar underpinnings, while large differences in weight indicate very different underpinnings.
We can NOT fairly compare IS to lighter C Class, and say that the GLC CUV is actually heavier than the Lexus NX CUV.
Why?
Because the GLC CUV shares platforms with the rear wheel drive C Class, but the Lexus NX CUV does NOT share platforms with IS.
The NX CUV shares platforms with the front wheel drive Toyota RAV-4 and Corolla.
Thus, the Lexus NX CUV normally drives its front wheels, while the rear wheels will only engage if there is wheelspin, ie loss of traction.
Thus, apart from weight and gearbox, we also have to consider traction as to why the C & GLC Class "dust" the Lexus duo in your own words...
Also I wasn't comparing to the NX platform with the IS, just mentioning that even then the acceleration figures are weak despite its weight (although it does have a 6-speed transmission). The NX has a sophisticated enough AWD system where it's 0-60 times (as C&D performs their tests) shouldn't be terribly affected by its setup. This was a comment in regards to the 2.0t missing my personal expectations.

When the most recent version was released in 2007 it was, on average $8k cheaper than the competition when looking strictly at the LWB MSRP. So in fact, it did bargain price versus what was offered elsewhere. It was a staggering $11.4k less than the SWB versions (Mercedes not included).
For 2017, I again compared everything just to the LWB since that's all the competition has, but since they offer multiple engine choices, I compared both to the current 2017 LS 460 LWB price. For 2017, the V6 versions of the competition is $2.1k more on average than the current LS 460 (excluded the Mercedes). For 2017, the V8 versions of the competition is $15.4k more on average than the current LS 460.
So where does Lexus place this? While the Audi A8 is due for a new model in 2018, the older 2017 3.0 is almost just as fast as the current 4.6, but the 4.0 tt is loads faster than the existing and proposed version of the 3.5 tt. The 3.0 sits currently at $82.5k, or $3.6k more than the current LWB. The 4.0 sits at $91.5k, or $12.6k more than the current LWB.
The BMW typically underestimates its claimed times, but for comparison's sake, the existing 740i i6 is probably faster than the current LS 460, whereas the existing 750i is also probably faster than the proposed 3.5. This car starts at $81.5k and $94.6k respectively.
Does Lexus undercut again? Let's say for simple hypothetical purposes Lexus "thinks" the V6 is equivalent to the V8 versions. And again, for simple hypothetical purposes, lets assume it undercuts by $8k. This would mean that the price might be $86k MSRP assuming it's a straight $8k under the average of the big three's MSRP.
Is it worth an MSRP of $86k?
Frankly, I think that's too much. They would be smart to price it the same as the competition's six-cylinder flavors imo. They could then say, hey, you can get a V6 version of the LS that's slightly cheaper than the the A8 3.0 or 740i, but it performs much better.
This is the MSRP it needs imo, if all it offers is that V6tt: $79k-80k
Edit: and I think it would be a mistake on Lexus' part to price it to the competition's V8 versions regardless of performance.
Also I wasn't comparing to the NX platform with the IS, just mentioning that even then the acceleration figures are weak despite its weight (although it does have a 6-speed transmission). The NX has a sophisticated enough AWD system where it's 0-60 times shouldn't be terribly affected by its setup.
Celebrating Lexus & Toyota from Around the Globe
When discussing platforms, be careful of the basic underlying design and it's effects on the vehicles, rather than the nomenclature & fine details.
Minor variations in suspension mounting points will not normally result in a chassis that's nearly 400 lbs heavier.
If the basic underlying design is similar, then the weight will be similar, and weight is what ultimately affects the vehicle...
