Lexus Champion
My expectation and requirement for a GS-F is 500 Horsepower minimum.
But you know what:
If Lexus uses that method that the parent company (Toyota) has used for the Toyota Tundra, then getting more than 500 hp shouldn't be a problem.
Here's the Tundra example
http://en.wikipedia.org/wiki/Toyota_...D_supercharger
The 5.7 liter natural-aspirated engine produces 380 horsepower.............but when Toyota slapped it with a pair of Eaton Twin Vortex Superchargers, wapak! Additional 120 horsepower = 500 horses in an instant.
If for example, Lexus were to use the existing IS-F engine (2UR-FSE), then the 410 horsepower unit will receive additional 120 to get 530 hp.
That and with the GS-F aiming for relatively lower weight, it should make for a deadly combination.
More power (500 hp or more) + lesser weight = a force not to be underestimated with
Just saying

Pole Position
I would prefer supercharger over turbocharger since turbo-lag is still present despite recent advances.
Another possible tech innovation is using small electric engines to power the front wheels for 4 wheel drive in low grip situations without the weight penalty of a mechanical AWD drivetrain.

Did you notice Toyotas recent electric racer setting new records at the Nurnberg ring? They are working on some interesting technology……

Why do you think "only 50hp max"? Regenerative braking helps, but the bulk of the recharging is from the gas engine at this point, although they are looking at many additional ways to recharge while driving...solar, exhaust/engine heat, etc. Plus many variations on energy storage… even current “in wheel motors” can deliver 200+hp each, we just need to keep them fed.

Update
Ever since the new Lexus GS 350 made its debut last year, we’ve been a bit disappointed that it doesn’t come with a V8 and that the brand has announced no plans to do a high-performance version that would compete with the likes of the BMW M5 and the Mercedes-Benz E63 AMG. Well, that could change.
Speaking to AutoCar, Lexus’ product planning chief Karl Schlicht would ‘love to see’ the a high-performance GS to make it into production. The model, which would be known as the GS-F, has not yet been approved by Toyota management, but he is trying his best to get the thumbs up. We’re not sure why Toyota management wouldn’t approve such a vehicle since it would give the Lexus brand massive exposure, but there’s probably some reason.
“With a GS-F, we would have a solid pyramid structure of performance models,” said Schlicht.
Power wise the model could carry the Lexus LFA’s 4.8 liter engine, which would be detuned to produce around 500-hp.

problem is not electric motors, they are already powerful as it is, but you cant recoup 150hp worth of energy... right now energy recuperation is already pretty advanced as it is.
and you cant compare what they do in F1 or very expensive race cars to real world technology.

lets be honest here, GS-F is coming out, they are just making nice story for press.... bad bean counters did not allow it, but our engineers worked at nights for 2 years to bring you this awesome creation!! :-)
