Mike, you need to moderate the PS forum...lol..

The GS350 will share the GR family engine with dual VVT-i, 16:1 air/fuel ratio and almost 1,800 psi of fuel pressure. It will produce over 300 hp( 319 hp from what I've heard) and good fuel economy.

The 460 will be the same platefrom with the V-8 directed injection, so I think the hp# will be a few more. I figure if the 3.5 can produced 319 hp, what about the 4.6?.

 

Wait so this summer Lexus will introduce the GS350 and the 460 to Japan or just the 350 and the 430? What will they use the new 3.0v6 after they put the 3.5 in the GS here? I know this has been discussed already but they should have waited and just released the GS either at the sametime with Japan or early with the 3.5 engine. When is the est date of the release of the 460? Great PS im sure if they came out we will see them downsouth with 2 tone paint jobs and 22" wheels

 

So they will have a 319 hp GS350 and a 300 hp GS430 to be released together in Japan this August ?
I know the GS430 could still have higher torque than the GS350, but that's an unusual way to differentiate if true . . .

 

Well as odd as it sounds, the latest generation 4Runner has done that type of power imbalance. The 1GR-FE 4.0L V6 produced 245 hp vs. the 2UZ-FE V8 4Runner's version previously running 235, 10 hp less back when it was released in 2003. Recently, the mid production year powertrain upgrade for 2005, the 4Runner V8 2UZ-FE has gained the addition of VVT-i which bumped HP up to 270hp.

 

The GS350, GS430, and the GS450h are all being introduced into Japan at the same time I think. Well the GS450h is already on the Japanese Lexus website. Here's where I got the power figure from.

It actually says its the IS350 that produces 318hp but that'd be the same for the GS350 I assume.

 

Ahh . . . that may not be a correct assumption, since they may not tune the 350 engine to produce the same hp for both the IS and the GS, like the G35 6MT has 298 hp & the M35 has only 280 hp . . . . . .

 

Probably because the GS350 wasn't ready to launch when they launched the new GS300 here and Lexus would have missed the opportunity to sell all the new GS300's they've already sold.

If the 3.5 produces 318 or 319HP, it may well be at very high rpms so its torque curve is likely to be very different to the V8 so even if max. horsepower is similar, the two cars will drive very differently. Still that's an impressive number out of a 3.5, especially since Lexus is getting good fuel economy too.

And Mike I doubt Lexus will keep the GS300 around once the GS350 is here because the pricing would be complex (GS300, GS300AWD, GS350, GS350AWD), unless Lexus (like BMW) does more to differentiate the models than just engines.

 

Hey Nuum, when exactly is the GS350 being introduced in North America?

A friend of mine wants to get a 3rd Gen GS but does not want the 300 or the 430, but does want the 350 and wants to know approximately how long he has to wait.

 

Unofficial sources have reported fall of 2006 as 07 model for introduction of GS350/460 . . .

 

All the rumors concerning the horsepower figure of the 460 so far have been pointing at exactly 350hp, which I think is quite realistic.

 

AmethySC is right. That is not an assumption that can be rightfully made. Rumors so far have all been saying that the GS350 is to be tuned for MORE horsepower than the IS350.

Please see my thread:

I don't see the HP numbers of the GS350 being higher than the IS350. Historically, the IS300 has had 10 less horsepower than the GS300. I wouldn't be surprised to see the same for the GS350.

 

. . . seems like you're contradicting yourself

 

No offense... but your 2nd sentence seems to contradict with your 1st sentence. Given that the 2nd sentence is a fact, I would have to agree with your 3rd sentence, that the GS350 will be tuned for more power than the IS350.

 

oops left a word out....

I don't see A PROBLEM with the HP numbers of the GS350 being higher than the IS350.

Fixed...there are you happy now?
