im new to the site and im planning to buy evo 8 in the near future. my concern is about "Active Centre Differential and
Super Active Yaw Control" is it available to u.s version of evo or just for uk version only? can we upgrade our u.s version to have that? or is there any news that it will be an option here in the u.s. because if it will be available in due time i will just wait for an evo 8 with acd and sayc. another thing do we still need traction control if your car is with acd and sayc.thanks.

 

Traction control Dude you'd have all wheel drive.

ACD, AYC, and Front LSD is only not available in the US. However a front LSD is available on the 04 Evo RS. The electronic diff is available on all evo's except ours. We get ours stripped because mitsubishi wants to make some $.

No you cannot install ACD/AYC due to the configuration of the emission control system and yes there is a possibility that it will come next year with an aluminum roof, 6-speed, and front LSD on all evo's.

 

so if you'r 4wheel drive no need for traction control...just curious why is that most suv (4x4) got a traction like volvo and others.

to bad for usa evo, i've seen uk specs evo8 fq330 it has 335hp but that is for £31,999($47,999,5)

you can modded your evo to 300 plus hp but at least in uk it will not void the warranty.

 

Yeah well the british one is 31,999 pounds!!! That's the equivalent of $57,557.53 !!!!!

 

But it has ACD/AYD (SAYD).. and its worth the extra pounds.. you wont believe it until you've tried it... with this stuff working.. there is no such thing as oversteer or understeer.. you point in a direction round a corner and the car goes there... its unbelievable.. and until you guys have it.. you wont know what you're missing.. If you read up on the reviews.. you'll find that its the ACD/AYD electronics that pushes the EVO's handling way beyond the STi or any other car...

 

I have never driven an evo with ACD/AYC, but from what I've read there seems to be some disagreement as to whether or not it's always a good thing. Maybe it's a product of "internet hype" (where a small, vocal minority can make their opinion seem more common that it actually is) or even just plain old stubbornness, but it does seem to be a contested issue. Some drivers claim that it "gets in the way", personally I'm not a skilled enough driver to make the distinction even if I had the opportunity to drive one.

I can tell you that for "spirited driving" on the streets, the US Evo has plenty of grip. I think that for anything less than racing on the track, ACD/AYC is not necessary. Fun, I'm sure, but not necessary. The only place where I could see its usefullness off the track would be in bad driving conditions (rain, snow, ice, etc.) where it might get you out of a bad situation. Personally, I don't encounter those situations often enough to warrant a large increase in cost -- plus, when they do happen I make sure to slow down an keep the car well within safe limits.

Of course, adding these features is also going to raise the price on the Evo substantially. It is also going to increase maintenance costs (which can already be high) so I'm pretty happy with the US Evo as it is. If it was an option that was relatively inexpensive I'd be tempted too, but I don't think we'll see it as an option on US Evo 8s. could well prove me wrong (and I wouldn't really mind ) but I just don't think we'll see that option in the US until (and if) we see an EVO IX.

 

Punds was referring to the british currency.. Not the weight...

 

SUV traction control systems are brake intervention systems that use the brakes to stop spinning wheels and transfer power through open diffs to wheels with traction. In other words, on a normal SUV with open front and rear diffs this system will allow you to get unstuck with traction on only one wheel. On a track at speed these systems do nothing for you. On the Evo, you have a rear LSD but an open diff in the front, so theoretically you can get stuck if both rear wheels don't have traction and you only have traction at one front wheel. These traction control systems also use an electronic throttle to cut back on the engine power if you're gunning it too hard to get unstuck.

However, since both axles on a 4wd car are turning at more or less the same rate, the data going into the system is not as good as it would be on a 2wd car, where the traction control computer compares the rotation of both axles to determine if wheelspin has occured. On a 4wd car, the system works by limiting the difference in speed between individual wheels. Not a big deal.

The purpose of traction control is to maximize the traction of the tires, usually to keep cars from getting stuck when they try to take off from a standstill. Another form of traction control is electronic stability. THis is similar to traction control in that it uses the brakes and throttle, but instead of using that intervention to keep the car from getting stuck, they are used to keep the car going on the path determined by the steering wheel angle. Stability systems have a lateral-g sensor, which the computer uses to determine how quickly you are turning, and compares that data to the steering wheel info, which determines how much the car is sliding. Brakes are applied independently to rotate the car onto the intended path. Sometimes the throttle is cut back. Different companies have different ways of implementing this. Family cars cut a lot of power and it is really meant to keep soccer moms and dads from sliding off the road in the winter. The corvette and porsche 911 have performance stability systems which can help you turn laps faster by keeping the car on the line the driver intended. SAYC/ACD are fundamentally different because instead of using brakes (thus reducing the actual power put to the ground) the system actively manages the torque split L/R and F/R to keep the car on the path. On a track this can be helpful to the right driver, but some find the system to be intrusive and high maintenance. Another reason mitsubishi left it off is because the 5000 mile fluid change interval is quicker than american customers can be trusted to obey.
