Gs 300 Mpg?
Gs 300 Mpg?
So, I was in Trig. today and got bored and started thinking about the new GS, as I frequently do. I was thinking that if the Avalon and GS300 are going to share the same basic engine but tuned slightly different, and if the 280HP Avalon already gets 22/31MPG...with an extra cog in the tranny and slightly less power, should the GS300 get better MPG figures than that? I know weight and gearing will be different in the GS, but I got to thinking about it none the less.
If so, that'd be awesome considering that fuel efficiency has never been a strong point for the current car.
Any thoughts or comments?

And you can't compare it with the Avalon, totally diff engine and FWD layout will give better milage.

The GS300 has a 3.0L V6, compared to the Avalon's 3.5L V6. Furthermore, the 3GR-FSE in the GS has Direct Injection, which reportedly ups power AND fuel economy by 10%. Based on a Japanese picture/spec sheet of the 3GR (can be found on IS300.net, news archives), the fuel economy is about 27mpg, if not slightly higher. This is city mpg, btw. It sounds almost too good to be true, since that puts the GS300 with a fuel economy near a Corolla, and higher than a Camry 4 cyl. But since the 3GR has 0.5L less displacement than the Avalon 2GR, as well as having Direct Injection, a city mpg increase of 5mpg over the Avalon seems very likely.
I believe we are in for many surprises to come from Toyota, in the next couple of years.

Avalon's 3.5 engine is extremly closely related to 3.0 in GS, and both have D4 injection. With 15% smaller displacement, and 6 speed AT, you should get comparably better mileage as well. So it should be really good.

Plus, those fuel mileage numbers are real, not estimates, at least as far as i know, since that spec sheet is apparently of the 3GR in Japan, which has been available for about a year now, on the Crown Athlete (correct me if I'm wrong here).

Direct injection is only available for the 3GR-FSE 3.0L & 4GR-FSE 2.5L for now. If and when the next IS comes with the 2GR 3.5L, it should utilize Direct Injection. You could be a little more nicer in your explanations!

Sorry if I sounded harsh, just was surprised at the statement of the 2GR in the Avalon being D4, since it's not .
I realize that the Japanese system is different: it's in km/L. For the 3GR-FSE (and interestingly enough, the 2JZ-FSE) the fuel economy is rated at 11.4km/L in Japan. Doing a conversion, you get *roughly* 27mpg. I'm willing to venture that the EPA ratings will be in *about* the same range. I understand what you mean by estimates, but the EPA estimates should not be too far off the Japanese quoted fuel economy. So to reword my original statement, I *estimate* the 3GR in the GS300 will have 27mpg city .
On the 2JZ-FSE, fuel economy is superior by about 20% compared to the port injected 2JZ-FE, although the JZ is Inline-6. From what I hear, in a V6, it goes up by 10%, but then again, Toyota could work some magic ... who knows.

Toyota will probably but it into every new generation of engines where it pays off to have the D4. They require better/cleaner gas which is why it was never featured in US or some other markets as well. I see no reason for 2GR engine not to have D4 technology, and considering that Avalon is its first application I dont see where would you read that 2GR has D4. They might still have some doubts about it - it is a bit more expensive and then again gas in US is of questionable quality. However if 2GR in Avalon doesnt have the D4, then 3GR in GS should be even more economical than very good numbers for Avalon figures!

I heard its a 20% bump in fuel economy.
I would love to ask, why the GS got the 3.0 and the Avalon and Japanese GS got the 3.5. I am dying to know the reason behind this decision.
The GS is supposed to be the "bad ***" Lexus, not the one with the best gas mileage......
We'll see. Clearly, the 06 GS 300 will be faster than the 05 GS 300. With better gas mileage.

First, I know that Lexus isn't a horsepower company but in the face of competition that is so powerful, they gave us two BRAND NEW cars that have the least amount of advertised horsepower, and some of the competitors are a few years old.
Second, the Avalon has always been the Toyota that could have been a Lexus, and IMO, aside from the badge it's a pretty compelling buy over the GS300. 280HP with an interior that's just as nice and even a bit bigger? I could definitely forego the badge for about 10K less when comparably equipped, and the Avalon Limited gets you a few goodies like reclining rear seats that the GS doesn't have.
Last, I might not be so puzzled if 1997 wasn't one of the best years in Lexus history. They blew away the competition with horsepower and in effect, established rather lofty standards. It just seems that it would have made sense for them to follow up and do the "proper" thing and give the car more power than the competition, just like in 1997
The only feasible conclusion that I can come to is that they delayed the 3.5L so that they could put the finishing touches on the rumored 4.6L V8, then introduce them together. Only speculation though.

Same engine is sold on some JDM models as well (Camry's engine varation with D4).

Sicklex, if it's actually 20%, that's even more surprising. That's quite a big %.
MPLexus, I agree. The only logical reason as to why they haven't released the GS350 is because it would most likely be too close power-wise to the GS430. Thus, they will probably roll out the GS350 at the same time as the GS460. The GS350 I'm guessing would then replace the GS300.
