The black vehicle in the video does not look at all like the LF-1 to me. And keep in mind it's a concept - if Lexus shows another concept of the LF-1 three years after the first concept with still no production model... not good AT ALL.
The prototype CUV on the track video is shaped like a GMC Terrain... I'm a little surprised to see something so squared off from Lexus.
Technology is awesome, and that demo was very telling. 80/20 RWD/FWD split... and still AWD... yes please!

Lexus have announced their next-generation all-wheel drive Direct4 system, which uses front and rear electric motors to drive torque to all four wheels — here’s a video deep-dive showing off the AWD system with two camouflaged prototypes and a concept we’ll cover later:
The sedan prototype is clearly the current ES, but what about the squared-off crossover? Could this be the next-generation NX or a brand new Lexus model?

From the press release, this DIRECT4 is impressive. Single electric motor for the front and rear with electric torque vectoring? I didn't see the word 'vectoring' though so maybe it's just shifting between the front and rear axle.
The system uses a front and rear e-axle, each featuring a high-torque electric motor and transaxle, focusing on optimum drive force distribution. As the motor is directly connected to the wheels by a single driveshaft, it operates without delay.![]()

The system is for:So is this system just for electric vehicles? If so I mean cool technology but some of us want better stuff on gas vehicles not just electric. I’m honestly not excited about the electric world at all and wish Lexus wouldn’t give up on the gas world but seems that ship has sailed.
I believe that you have answered your own question regarding the use of Direct4 on eTNGA EVs: Direct4 electric-axles may be used on (plug-in) hybrid electric vehicles and pure/battery electric vehicles.It seems to me that Direct4 is something that will be available on many TNGA vehicles and not necessarily just eTNGA - it is a drivetrain component.
eTNGA is the flexible electrified platform coming soon, and I assume that too will likely also offer Direct4. This platform will not have a gasoline engine and will support future EVs.
I suspect that TNGA (all unibody variations) and eTNGA were developed together and are related. If we look upon TNGA-K, TNGA-C, TNGA-N, GA-L, etc. as modular platforms, eTNGA may be just another variation on the common theme.TNGA just rolled out 4 years ago and there is no way that TNGA-K, TNGA-C, etc, are going to be abandoned for eTNGA anytime soon. Most likely, this stuff will exist for another 10-20 years because of development time and costs, infrastructure, and because Toyota sees BEV as just one part of their strategy. We are going to see continued development of gasoline engines, hybrids, plug in hybrids, high performance hybrids with Direct4, hydrogen engines and battery electric vehicles (no gas engine).
A front/rear torque distribution system is still a torque vectoring system. In this case it actually works better than left/right vectoring while using less hardware.From the press release, this DIRECT4 is impressive.

3) Video of two running prototypes with Direct4, one was an ES and one was another unknown CUV.
I think the second prototype (next to the ES) is just a test mule GX for the running gear of the yet to be revelead concept (perhaps the RZ450e concept).
I think this because it really looks like a GX and it doesn’t do a lot of sense to make a BEV with, what it seems, so bad aero. Aerodinamics makes a huge impact in real world range on BEV’s...
Also, GX would provide a lot of space for batteries, sensors, electric engines, etc. And it wouldn’t make any sense to say “here is a teaser for a concept that will show our future” and also show a real future model...

It seems Toyota does not want a 3-motor interim solution with front/rear vectoring and rear left/right vectoring and would instead go from 2-motor to 4-motor directly, and it makes total sense.

The rear wheel drive GS and IS have the option of AWD. So Lexus has had RWD based AWD systems for quite some time.This kinda convinces me that the production LF-1 may not be offered in a gasoline-only option. Lexus previously only had an AWD system in cars other than the LX and GX that drives the front tires normally, and sends power to the rear only when traction is needed (not 100% sure of my accuracy here). Lexus needed a proper dynamic AWD system to compete with the likes of Quattro, xDrive and 4MATIC in cars like the Q7, X5, etc. in order to have a competitive full-sized SUV like the LF-1.
Now Lexus has introduced a system, but it only works with electrified vehicles. If my hypothesis is true, this also means we probably won't see a V8 powered F-SUV ever.
