How much faster Evo w/ S-AYC vs Evo no AYC?
#18
In layman's term, think of it this way. With ACD, you can transfer the cars traction from front to rear, Tarmac - more traction to rear, in slippery roads more traction to front. Now with Active Yaw Control you can transfer the cars traction from side to side. If your turning around to the right of your mailbox, your car's traction is transferred to the left front and left rear wheels. This means that the car would be turning tighter on an apex.

3 makes no sense either. Maybe he would like to learn more about it? He doesn't know anything about how to use his current Evo - I don't see how buying a X just to get the new S-AYC is going to teach him anything new. Instead of blindly defending, how about actually reading and paying attention to what is being said? It would be very foolish for him to sell and re-buy just to get a feature that he doesn't even know anything about, especially when he hasn't even begun to learn how to use the car he currently has. It's like people who upgrade their sway bars and springs without ever once racing their Evo...makes no sense.

I tought evom was to help each other make the right choice on modding with out spending $$ for useless things. S-AYC ofcourse is not usless but if you dont know your car or track it then there is no reason on tradeing what you currently have to have that option.

I've seen various comparisons on different model Evos with different equipment, and the ayc acd doesn't make a difference on a race track. It seems the technology was made for the everyday "idiot" driver. Safety devices if you will. I'm sure the will help in inclement weather as well. But a race track is as close as you will get to an "optimum environment" so who knows.

If a guys wants to buy or ask questions about XYZ or ABC, he does not need permission or a lot of grief, criticism and talking down to from anybody in these forums. Warrtalon might be a good driver and his car might be fast. He might also be Als' and DBs biggest fan, but he often comes accross as an insulting know-it-all, and you come accross as a me too yes-man

Two things to note about manufacturer comparisons...
First off, obviously they will be biased, as they are trying to sell the new product. But perhaps more importantly they typically don't compare apples to apples. For example Audi showed the S4 performing on snow with ESP on and off, without a disclaimer that switching the ESP off results in an OPEN DIFF front and rear. Obviously this results in horrible performance. AYC may work similarly, Mitsu may (probably does IMHO) be using a SAYC rear diff with SAYC turned on and off, resulting in a similarly open diff as opposed to the LSD diff the car currently has.
Every recent mass produced drivetrain technology that I've run into seems to be geared towards safety, and usually hampers track performance. All recently developed traction control devices certainly do not help performance at all, but they do keep you from going into a ditch in a rainstorm. It's a bit of a tradeoff.

I asked this question a while back. Not because I want SAYC but, because I saw an article in CAR magazine with the SAYC equipped IX FQ320 blistering the Audi RS4 by about 4 seconds a lap. I was waiting for the "Our car destroyes the RS4 around a track" comments to start which, got me thinking "that isn't really our car though" since it has SAYC and no one seems to know how much SAYC is worth around a circuit.
I just thought it would be interesting to see how a non SAYC IX's times would compare on the same course with the same driver. Maybe some of our over seas friends have compared them but, I haven't seen any definitive data.

I would think that the front heavy S4 has a tremendous weight balance handicap. Certainly my old S4 had a terrible push / understeer problem that the Evo does not suffer from. I'm surpised the Audi was even that close.

That's what they said the Audi just plowed through the corners and weighs a fair bit more but, it does have 415 HP though. That's almost a hundred more than the Evo in that comparo.
Even with all that understeer the RS4 was faster than the M3 CSL around the same circuit.

Gentlemen,
I asked a simple question, given a the same skilled consistent driver over a road course with two cars of the same year but different platforms, One Evo IX GT (No S-AYC) vs One Evo IX GSR (With S-AYC), about how much of a difference would this make? I'm not an idiot of course I'm not going trade the car in just for this AYC/AWC I was just claiming this to get some real responses, I've read how it works.... all I want is a simple answer, 0.5 seconds, 1 seconds? 2 seconds?? Can somebody from outside the US who has experience with this AYC stuff chime in?..... Australia, UK, Japan answer to this?

Thinking about this some more I believe the main function of SAYC is the same as ESP, which is induce oversteer in push/understeer conditions. ESP does it by braking the inside wheel, SAYC does it by transferring torque to the outside wheel. In practice this would have the EXACT same effect. Also in practice understeer usually occurs when apexing too early. I bet the videos showing SAYC have the driver doing just that.
But to answer the question, the key to driving a track course is handling predictability. SAYC doesn't give you that, so I bet you'd be SLOWER with SAYC than without it, assuming you apex correctly. If you don't know how to drive, then yes the car would be faster with SAYC.
