Everything exist already, is basically adding the drivetrain of the plug-in liquid-cooled lithium-ion battery technologies from the Testa Roadster to a ISF or LFA gas motor.
AKA 918 Spyder.
The biggest challenge they have to solve is how to package all that stuff into a sedan without taking up the entire trunk, and to lower the cost. A Testa Roadster without a gas engine is $150k, 918 Spyder that comes with everything is $850k.
Kinda like adding a $150k Testa Roadster to a $440k Carrera GT = 918 Spyder.
In Toyota's term, is combining a Testa Roadster with a ISF into a LS body and sell it for less then $200k. It could be done, since a ISF is much cheaper then a Carrera GT.

another way to look at this, looking at the spec, it seems like toyota has discovered something new and a solution to a long time problem. lower rev but more tq vs higher rev but less tq.
just imagine high low end tq for daily driving to make it even more manageable (and quieter), but when needed, push it hard and it keeps on revving and then the screaming engine tone. now that's so sick

HP = [(Torque)*(RPM)]/5252
Here is a decent introduction to HP, torque, and RPM -
http://www.epi-eng.com/piston_engine...and_torque.htm
For a given HP, an engine that revs to 9000 will inevitably have small low end torque by virtue of the relation above.
The only practical, mathematically-viable "solution" to the problem of high revving engines having small low end torque is to produce a high revving engine with extremely high HP.
If you want to maintain 9000 RPMs but you also want sufficient low end torque, the only solution is to increase HP. You can't maintain a certain HP and high RPM and then try to artificially increase low end torque, because torque and RPM are inversely proportional to each other.

No that's mathematically impossible. Torque, horsepower, and RPM are related to each other by a fixed formula. Specifically, for a given HP, torque and RPM are inversely related -
HP = [(Torque)*(RPM)]/5252

for all i care, toyota has that spec sheet with the numbers shown that you can read (of course granted there are no typos on that spec sheet)

i am very ware of the famous equation. you have to read what i said again and also few posts back, i said this has to be FI or hybrid. it's impossible on a NA setup, but possible if there is another power source, for example say hybrid, which adds a lot of tq

Makes no sense, at all. With such long range you want, it would literally weight 3 tons, not to mention the costs.
Smaller range would mean you would be left without the juice on the track.
This is why PHEVs are usually made with small gas engine.
Why would you add PHEV system and raise the price of vehicle by... 50-80k? just so you get same performance as if you would turbo it (sans the 50k of course).

Okay....I simply think its a tuned 5.0 with a super charger....Lexus engines outside of the LFA (which probably is someone held back for reliability) have low peak RPM and never are maxed out, they keep HP low for reliability. This to me is maybe a peak effort so again, that means 500-600hp should be reliable if produced.
Has a DTM look with those huge fender flares.

it would be pure awesomeness if they create a FI setup (or any setup for that matter) with that kind of high power and tq AND high rev. i get goose bumps just thinking about it. pair that with toyota's reliability, wow what else can you ask for

Lexus Champion
The back seat is gone (or so it looks), this to me gave a hint at hybrid power. Lexus is hybrid, toyota is hybrid, why not show the world you have the best and most powerful hybrid? I seriously think the car was cut down in the weight department but the powertrain has gained it back. Why would Lexus have a twin turbo V8 when they just dropped the V8 from the GS lineup? Unless this is a testbed for the GS-F, I don't see a point in having such a powerful engine. Then again it might just be a special project? It's confusing for certain, but I do think this is a hybrid of some sort.

confusing or not i think it's just great that lexus is doing it
