front looks more like a saturn sky, pretty sweet. IS-F would look a little better with some design cues from this car, tone down the front bumper a little. Love the grille where the L emblem is

 

Nice pictures Javy.

 

This was only Phase 1 of the project..


Not many people know/knew that there is a PHASE 2 to this project

That is where they will focus on the Performance, Engine, etc....

With a goal of 600 hp, I can't wait to see the finished project. It was also funny to finally see the Brembo GT kit that was developed on MY car...

600 hp from 5 litres should be a cakewalk. I'm really disappointed the hp/litre on the V-8 is actually quite a bit LESS than on the V-6 3.5 litre.

 

i think lexus did it that way to get good emission ratings?

 

Emissions/economy is a lame excuse. This engine has G series heads. It is supposed to be performance oriented, but obviously the 2GR is more performance focused than the 2UR. I don't buy the economy BS at all. It's not hard to tune for economy with variable cam timing on both intake and exhaust. Lexus should have set a goal of 90hp/litre and made a full 450 hp to shut up the competition.

The fact the V-8 engine has to wind out to almost redline for peak hp indicates a fundamental choice they made in the engine configuration that limits power pretty dramatically compared to the V-6. It's overall a big disappointment IMHO.

I realize this is no Ferrari and expecting 100+ hp/litre from an NA Toyota is unthinkable, but 90 hp/litre is nothing special these days. Just look at the competition for a "how to" guide.

 

Not if the engine will stay naturally aspirated. We don't know the specifics of what Five Axis is planning and if any Toyota partners/Toyota themselves are helping them. We'll have to wait and see what they achieve.

The 2GR-FSE achieves 87.4 HP/L and 79.14 lb-ft/L. The 2UR-GSE achieves 83.2 HP/L and 74.2 lb-ft/L. It's not that big of a difference really. The 1UR-FSE achieves even less HP/L than the 2UR-GSE. I think it's more of Toyota having a bit more experience with V6 engines compared to V8 engines and also a matter of tuning in terms of fuel economy.

It would be easy for Toyota to boost power on the IS-F without worrying about fuel economy. Making high HP and torque while still having fuel economy a top priority is a much greater challenge. Obviously with the RS4 and M3 fuel economy was not a top priority.

The IS-F makes high power and provides high performance while still achieving great fuel economy.

Lame or not, it seems that's what Toyota has done. The engine seems to be tuned for fuel economy, and it seems that Toyota specifically wanted to beat the gas guzzler tax. As it stands, the EPA numbers for the IS-F are 16/23 and the combined mpg is between 21.5 - 22.

That puts it in the tax bracket of only $1000.

I should also point out that HP/L doesn't mean a whole lot and despite all the praise the RS4 and M3 engines have gotten, the EPA numbers for those cars are lower than the IS-F.

The IS-F has best-in-class fuel economy, and that counts for something if you're talking about bragging rights.

I think the engine is capable of far more, and that Toyota purposely detuned it for fuel economy.

To compare, the IS350 achieves 18/25 EPA, only 2 more mpg in both city and highway compared to the IS-F. The IS-F weighs more, has a higher Cd of drag and makes much more power than the IS350 not to mention offers an overall more performance-oriented experience.

To compare, the RS4 gets 13/20 EPA and the M3 is estimated to get 13/20 EPA as well. As a result, the gas guzzler tax on those cars will be quite a bit higher than the IS-F.

 

incredible car!
greetings to whoever helped in designing it,nice job.

 

Isnt the whole point of a car in this segment to perform? If someone wanted an economical IS they could buy a 250. If they want power and practicality they can buy an IS350. And it would make sense that the IS-F would be the big F economy and go for performance. I agree with lobuxracer. I think lexus had an opportunity to do a lot more than they did. I still like the car I just wish they would have gone all out. Ferrari isn't the only company with an F1 team. Maybe Lexus should have pulled some engineers from Toyota F1 to get a little more out of the 5 liter v8. Not that its really a fair comparison but if they can get 700+ hp out of a 2.4 V8 (I think) then it seems like they should be able to get at least 500 out of a 5 liter.

 

would be crazy to have the IS-F at 500hp...but dang...everything will go out of wack...I mean the GS-F (if it comes out) will have to have at least 600hp or more...and dang...ever competitor will start cranking out higher and higher hp...heh...maybe in 10 years...there will be stock cars (like bmw, benz, audi, lexus) with 1000hp or more...haha

 

Maybe the buyers don't care about fuel economy, but Lexus as a company has the responsibility to do so. They provide a car that is bang on par with the competition (the current competition i.e. the ones coming to the market at the same time as the IS-f), with markedly better fuel economy.

I mean, yeah. I am sure that they could have EASILY made 500hp with that motor, but Lexus as a company has its design musts, and I think it is quite noble of them, so I'm not gonna bang them over 20 more hp when the car accelerates with the best of them.

Have you people not heard of CAFE standards and stuff like that? I mean, i hate greenies as much as the next guy, but these things are going to be held legally accountable for a company. Lexus is looking to the future.

 

Yes, Lexus COULD HAVE done more and made the engine output more power. That I agree with.

What I don't agree with is criticism that the engine can't make more power. This engine has A LOT of potential, and these words will be vindicated soon enough. Before the car even hits dealers, we will see the engine's potential with Phase Two of the Five Axis IS-F.

High fuel economy might not matter to most enthusiasts, but I'm and enthusiast, and it matters to me. To be clear, it doesn't matter to me just in terms of economics, it matters to me in only one sense; bragging rights.

Plain and simple, as an enthusiast (and were I an IS-F owner) I would have bragging rights that my car makes high HP *AND* gets good fuel economy *AND* gets low emissions. C63, M3, or RS4 owners won't have these same bragging rights.

 

Hey guys its been a little while since I was on here so I hope this is the most appropriate forum for this. If not Mods please move it for me. I was at SEMA last week shoot some photos and thought I would share some of the IS I saw there with your guys.

5 Axis IS-F





Thing looked awesome in person. I swear I shot more IS pics but I guess I didnt. I'll have too look on my other memory car and post them up if there is more on there.

DAMN!!! That looks tight!!!


Is that a flat black paint job?
