Hmmmm.....as far as I knew, the GS450H was going to be a V6 hybrid. But a V8 hybrid, if that's the case, will make the GS450H more powerful than the upcoming GS460, unless Toyota is introducing a brand new V8, instead of stroking the current 4.3L. To me, at least symbolically, would make the GS450H the "GT" version .... unless of course, the "GT" version, hypothetically spkeaing, will be something even stronger

There is alot of conflicting info about the 450h being a v6 or v8. I'm still... 
The real preliminary stats on the GS450h should surface shortly. I personally feel Hybrid technology is definitely something to be excited about.

actually, it would make little sense to me to use V8 since then they would lose advantage of better mpg in V6. 280hp V6 plus 70hp electric engine would end up as pretty powerful combo, in both mpg and power sense...
BTW - RX400h = 330hp + 70hp=400h
GS450h=280hp+70hp=450hp
And also, like in Prius, gasoline engine should be "detuned" to deliver better mpg and torque so it probably will end up having a bit less hp than before, yet with the help of electric engine go much faster overall. (i am picking this up from my head, but 105hp engine in Prius was detuned to some 87hp or something similar).

Very interesting math.
280hp + 70hp = 450hp
The RX400h has been confirmed with 270 hp and not 400 hp.
With hybrids horsepower is not where the advantages is. It is the instant available torque from the electric motor at low speed.

E. Quieter, since the car is silent when only being ran on the electric engines

And yes, what Lexus and Toyota are going for is Performance and at slighter level, saving the world (economy, emissions).
p.s. 70hp is in Prius, it is unknow what exact system will RX400h have... In fact, it should have 2 different options (AWD and FWD drive systems).

Expanding on 1Sicklex's point C - lowered fuel costs for any fuel efficient vehicle means lower total cost of ownership. For instance, if I was driving a new prius instead of my GS400, I'd save approx $80/month in fuel costs, over the 4yr loan term of my GS that would save $3840, not to shabby.
