the best AWD system
Active Yaw Control was copied by honda and renamed "super handling all wheel drive". I believe that is the best AWD platform there is since it drastically improves cornering. It existed in the Lancer Evolution VI and there after only on JDM and Euro models. But they are much higher priced...Audi does not have anything like that....but they have been refining all wheel drive for over 20 years.

I would say SAYC equipped Evo's have the most advanced AWD for a street car. I would also say the WRC cars have the most advanced AWD systems there are. I don't care what car it is in WRC its AWD is nothing close to the same as what the street cars are eqipped with. We are talking application specific designed only for motorsport type diffs. here. The AWD drive systems in a WRC are much more advanced than anything we get for the street.

I don't know much about the Skylines, you can switch to just RWD right?, that's pretty high tech =p

thanks for the great post. There are so many ways to design an AWD car.. but i'm very happy with the performance of the ACD in the Evo. I wish the Mitsu engineers could have figured out how to fit the Super AYC system into our U.S. Spec cars though. Might have helped to reduce some of the understeer at the track.
the real evos have the best awd system in the world hands down. super acd and super ayc allws the car to bea 1 wheel drive if nessacary. HANDS DOWN ITS BETTER THAN AUDI.. the s4 has 2 open diffs.

Nuttin came close to this AWD system. The quattro is... audi just i dont kno its just too luxury, i dont think it has a sporty side( screw the S4).
Porshe is excellent too.
hey about the Evo?
what about the STI's AWD system. i think it was 5th gear that tested the jdm sti and evo in the wet, and the sti bet the evo in almost every test. they said it was able to distribute the power to the ground better

Just to set the record straight, Honda's SH-AWD can vary torque FRONT AND REAR and SIDE TO SIDE to all individual wheels, up to 70% if I'm not mistaken.
Evo's S-AYC only transfers REAR TORQUE from left to right wheels. The front/rear distribution remains at 50/50 at all times.
