Sorry for the incoming wall of text, but lets get this straight before we misinform everyone any more. The description Hibby posted about the Evo's ASC system in NO WAY reflects the system in the Outlander, any non-EVO Lancer model, or the 2009 Eclipse GT, let alone the new RA, assuming it has ASC. All of these other models control ASC using 4 wheel speed sensors. The achieve stability control by breaking and cutting throttle. IE: they slow the car down if you lose traction. The Evo uses the wheel speed, yaw rate, steering angle and break pressure sensors. It will only apply minimum breaking to the wheels that lose traction, and will shift power away from those wheels without cutting engile throttle, but will keep pushing on the others that still have grip.

The eclipse never had ASC. The first eclipse to ever have ASC will be the 2009 GT model. Since the Eclipse cant shift power between wheels, its ASC just applies the brakes at varying force levels and cuts engine power for you if you lose grip in a turn (ie: no drift for you). Only a safety system.

The Lancer only has ASC in Australia, on all models (ES, VR, VR-X). Being the Australian plant was just shut down and all model production has stopped, I think even that may change. I have not heard any confirmation that any US models would get ASC, but if it did... it would again be a safety system. I honestly have not followed the all the 09 GTS details, but if you have a Mitsu press release, I'll buy it. But still, its not the same as the Evo's ASC.

Bottom line is all that ASC is a safety feature only, not performance features. It hurts performance. The Evo X uses ASC as a performance feature by integrating it with other systems that the RA doesn't have. Thus, 'ASC' in the RA != ASC in the Evo.

The Evo ASC system is not just a 'we lost grip, so lets automatically brake and cut throttle' system. It is controlled by the S-AWC (Super All Wheel Control) ECU and relies heavily on the AYC and S-ABS systems, which the RA lacks. So we don't go further down this tangent (again... we do this in EVERY 09 ralliart thread), lemme try to break it down and show the differences between what it means in the RA (or any other non-evo) and Evo X.

S-AWC: Made of 4 primary systems, which all send their sensor input to the S-AWC ECU, who then relays that info the primary ECU, where is combined with engine inputs and transmission inputs to control the driving characteristics of the car via outputs in all 4 S-AWC systems.

The systems are:

Active Center Differential (ACD): Both the RA and Evo VIII/IX/X have this. It uses a multi-plate clutch differential. It adjusts clamp load, letting torque be shifted between the front and rear wheels in order to gain the best traction and steering. It can split torque as much as 80%/20% in either direction. But, if traction is lost, at least 20% of the engine power still has to go to the unstable wheels in the RA. Thus, it will cut throttle until traction is regained.

Active Yaw Control (AYC): The RA does not have this. It works in the rear differential, and acts like a limited slip differential, allowing torque to be split between the two rear individual axles. Unlike a LSD, its electronically controlled, so it can take advantage of other inputs besides wheel speed. It uses sensors to detect body roll along the vertical axis of the car to determine the rear wheel power shift in order to limit the roll, thus improving traction through the corner. Since you can adjust power 80/20% front and back, and 0%/100% left and right, you never need to throttle power unless all 4 wheels have lost traction. And losing traction in all 4 wheels is more difficult because of this

Sport Antilock Breaks (S-ABS): The RA does not have this. Uses wheel speed, yaw rate, steering angle and brake pressure sensors to apply breaking while entering a corner. If this all works well, traction is never lost and the ASC system is never used. Instead of cutting throttle, it shifts power to wheels who can grip, and applies just enough brake for to wheels that cant. This system is used by the ASC system in the Evo to apply breaking, if the ASC is needed. This is the major difference between the Evo ASC and other model's ASC.

Active Stability Control (ASC): The concept is the same as any other ASC: to regain traction if its lost. Because of the S-ABS and AYC systems, power never needs to be cut if there is traction at any wheel. When brake pressure is applied to regain traction, it is only applied to the wheels that are lose, and only enough is applied to regain traction. Then power is reintroduced and brake force is removed. Power is never cut at the throttle, but is instead shifted away from the unstable wheel. The net effect is more speed through turns while regaining traction.

So to sum it up:
ASC in the Evo: keep maximum power to all stable wheels and minimizing breaking, while maximizing speed.

ACS in all other cars: Cut engine throttle, apply uniform breaking until traction is regained, minimizing speed while maximizing traction.

 

Shizz. My bad. At least it's got an ASC defeat.

 

no worries. i've been trying to make that point for over 2 weeks now, and it never sunk with most using a 1 or 2 line explanation

 

went to the Toronto autoshow today and they had Ralliart production vehicle #25 on display. Should of took more pics
It had the Recaros, Rockford Fosgate stereo, moonroof.
Wouldn't let anyone in though.
Mitsu reps were useless...had no clue about when it would hit showrooms.

 

this should not change anything with the lancers in australia, the only model being produced there that i am aware of was the 380. - in aus we only produce large family cars, falcons, commodores, etc. small cars are all imported.

my 06 RA imported from japan
my mums holden astra imported from belgiem(sp?) - also the wipers and indicator levers are around the wrong way...

 

Mitsubishi has intentionally kept this car quiet because they didn't want to take away from the Evo's launch. Now that the Evo is out, we should start to see a trickle of information.

 

What I found funny was how they had the Ralliart and Evo's all locked up like they were some sort of Ferrari's that nobody could sit in...atleast there were a few STi's and higher end cars that you could sit in.

Mitsubishi really had a poor and boring display going on...how many cars did they have that you could actually sit in that weren't boring to look at? lol

 

Why do the pics have the car running on Dunlop Tires?

 

Probably because they're cheaper and last longer than the tires they intend to offer. No point in wasting nice tires on a test mule.

 

I've been following that bad boy in the magazines. I like the idea of it. Turbo diesel, 300 ft/lbs, S-AWD, AYC etc. etc. We wont be seeing that one for a long time though IMO

 

Do you have any more then the 2 pics?

 

Is the RA interior identical to the GSR's?

 

thanks for the wall of info...BUT i believe the original question was whether or not the RA had ASC... and IMO it most certainly will. will it have the same kinda ASC that we see on the evo? probably not, i never said that it will. all i said was that the concept lancer RA had ASC (in whatever form), and so do countless other mitsu cars (in whatever form).

perhaps in your mind the distinction of evo x ASC and ASC in general was very clear, but the previous posts do not seem to mention this.

also do you have inside info? at this point, how certain are you that the RA AWD system does not have the wheel sensors, yaw sensors, etc? the reports were that the RA uses the IX drivetrain but what if it's a dumbed down version of the S-AWC found in the evo x except they don't wanna tell us because it might hurt evo x sales? just playing devils advocate. i personally don't believe that the RA ASC is like the evo x but unless you know for sure.... ya never know

lastly i'm pretty sure the center diff is split is set at 50:50. ACD simply modulates the lockup to achieve torque splits from 100:0 to 50:50.

 

nope, no inside info. I'm just another schmuck on the internet but I do use my eyes and my common sense. Look at the underbody MR pics and RA pics in here: https://www.evolutionm.net/forums/sh...318463&page=25

The MR has additional wire looms and plumbing complexity in/near the caliper. If I were a betting man (it seems like we're all speculating now, anyway), i'd guess thats part of the S-ABS system, specifically the brake pressure sensor. The lack of such wiring the in under body RA pics indicates.... you guessed it, a lack of a brake pressure sensor.

Not to mention that Mitsu has already put together marketing materials, press releases, dealer training material and car show presentations on the vehicle, and none of that mentions ASC, S-ABS or AYC (actually, the did go into detail about the rear diff with no mention of AYC). I mean, these are features with almost a decade of R&D for a specific application: Evo. Its hard to believe they 'forgot' to mention it, when they remembered to mention additional bullcrap like fastkey and bluetooth phone support. In that respect, they also failed to mention ASC at all... probably because any form of that is supported is not performance oriented. Bragging about it in a performance oriented model would be like saying 'it has airbags!'.

edit: btw mods, there really isnt any new info here should this be mered with the official 2009 RA thread?

 

Is the RA's interior identical to the Gsr?
