i want to see a torque curve of this GS450h, low end there will have ferocious torque because of the electric motor, and torque is probably very high everywhere else

on a related note, this will hint what kind of supernatural times a LS600h will have, probably 4.5 seconds or less while making mid ~20s mileage, hello mr porsche watch this huge sedan smoke you

in other news, many angels are reporting getting a wing, hybrids for teh win

Och

Any word on that LS500GT with v10 supercar engine?

Gojirra99

If they decide to produce the V10 & put it in a sedan, I would like it in the GS first, but a V10 SC & LS would be nice too . . .

they said there will b ea ls500gt with v10? i wouldn't look that far, we haven't even seen the ls600h yet

and 4TehNguyen, the ls460 is already getting mid 20s gas mileage. so on the ls600h, probably it will be even higher. if it's in the high 20s i will be very happy already

due to the way how CVT's work, torque and hp curve is dead straight at 6,000 rpm. Once you press pedal to the metal, you instantly go to maximum rpm mode.

Yeah I've been a BMW fan for a minute and what Lexus is doing now is crazy 5.1 0-60 for the IS. the gs hybrid in 5.2 when the new GS come out like my man Hova said IT'S OVER

Well this should be something. The Charger SRT8 which weighs in at 4160 (probably not that far off what the hybrid will weigh) and has 425hp does mid to low 5s, 0 to 60. I think I saw somebody got it into the 4s but most of what I have kept in mind said mid to maybe low 5s - 5.2 or something. Even ChryCo just says slightly over 5 sec for the Charger SRT8.So with the speculation you guys are making for the various LS and GS hybrids and the gas 460 I guess the transmission is going to have one low first gear on it. Heck, that transmission is going to be something because the best bimmer has for its puny 500hp M5 (at 4035 lbs) is 4.5 sec. 0 - 60, something that you guys believe is in reach for one or another of the hybrid or gas versions. Can't wait for the first real tests to come out.

Ron, 2 real tests have gotten a 5.2 sec and 5.5 run in the 450h

And unlike those cars, this GS will get literally twice the gas mileage.

The tranny in the GS450h is CVT, so its always in the right gear.

The M5 won't be a 0-60 champ, as it has low torque, 368lbs. The E55 in comparison has I think 514 or so. Where the M5 excels is at speed.

The GS 450h, with the throttle to the floor, probably has more torque than both cars, based on it having an electric motor

I don't see the LS being much faster if any faster, b/c it will weigh more. IF this GS weighs 4100lbs, I expect the LS to weigh 4500lbs.

Sorry, I saw the C&D excerpt with the "est." printed so I do not believe that that was any sort of a real test. I didn't do a lot of searching but I didn't see the test that measured the 5.5 sec. It doesn't seem like there is much point in this model from a performance standpoint if it doesn't get at most the 5.5 sec. time. But you are probably right about there being some torque influences. C&D says 0 - 60 estimated to be 5.2 but quarter mile at 13.9, which is indicating that it is going to be bunny rabbit quick off idle, if Lexus lets the tranny and engine management system do that, but not quite so quick once it is moving. Afterall, my 2k1 is a low 14 sec. quarter mile car but is hard pressed to make it into the 5s on zero to 60 and I only have 300hp total which is what the V6 alone is rated for in the hybrid GS. So I guess that once you get going, the electric motor isn't contributing much to acceleration which probably makes sense.

I am still not sure how you rate the power of hybrids but if C&D says that it has a 300hp gasoline motor and a 200hp electric motor, I guess everyone is believing that you combine those for the equivalent of 500hp. That's not what I would do but some people seem to feel that is the way you guesstimate performance. Lexus nomenclature is a bit confusing here as they seem to put a number that is more representative of an equivalent pure gasoline engine in performance which would mean a 450h would not have quite the performance of a 460. I guess we will find out when somebody does some testing on the RX350 compared to the RX400h because I think they are going to be equivalent in real or calculated hp.

But if the numbers are not estimates and have actually been timed, then the hybrid looks like it is in the SRT8 category, with better milage of course. If CVT put its anywhere near M5 territory, that's quite an impressive achievement and one that I wouldn't imagine would be possible on most any level. I guess we don't have long to wait. By this time next year there are going to be a lot of magazine comparos with low to sub 5 second 0-60 Lexus models around. I guess we will come back to this thread and review everyones prognostications at that time.

Edmunds actually tested the GS450H at 5.5 sec. 0-60 (They got >5 sec. times for the current M3 LOL whereas other sources got sub. 5 sec. ) & a European source tested the GS450H at 5.7 sec. 0-100kmph, which should translate to 5.5 sec. 0-60 mph . . .

RON430

Do you have the link for the Edmunds review? Thanks.

Gojirra99

The editor-in-chief at Edmunds did a brief review after testing the car : http://blogs.edmunds.com/.ee8f874

RON430

Thanks very much. They do say that they had an instrumented 0-60 of 5.5 although they didn't put in a quarter mile time. Now if C&D printed their estimate of 5.2 0-60 with 13.9 in the quarter and Edmunds got 5.5, it should be interesting to see what Edmunds (or anybody) gets in the quarter. I certainly know that a plain old 2K1 GS430 with only a 300hp dyno motor can do low 14s so it should be interesting to see what the hybrid can do.

I doubt that an M5 owner will have any trouble passing a 450h, at any speed. Passing a gas station might not be so easy.

umm, high 13s for quarter mile, i would expect more, considering that the is350 has done low 13s for 1/4

Thanks for the link. Good to know how GS450h is superior to the previous hybrid models from Toyota. Makes it even harder to wait to see the ultimate of the hybrids, the LS600h.
