No, just AWS. You might be thinking of ALB (more popularly ABS), which was badged on the back of that particular model.
 
That was this model.

Sorry about the anodised badges. People who anodise their car's badges should themselves be anodised.

i think all wheels turn and the same time (all to the left or right)

I believe it's speed sensitive, actually. At low speeds, the rear wheels turn opposite the front wheels, giving a smaller truning radius. At high speeds, the rear wheels turn the same direction as the front, for more stability.

I know many AWS systems work this way, not sure if this particular one does.
 
Most AWS systems work the same.

There's several thousand '88-92 MX-6s and 626s with 4ws, but they are rare.

Basicly, B Campbell summed it up well. At lower speeds(like up to 25mph) the rear wheels turn opposite the fronts, at medium speeds the back wheels don't turn, and at highway speeds, they turn the same as the fronts to cause the car to virtually move sideways into lanes.

Pretty cool system, but there's a lot of parts to break down.
 
The Honda system had the virture of being mechanical and fairly simple - it did make a bit of a change to the car, particularly for lane changes at highway speeds, but certainly the benefits weren't sufficient to justify the weight, or as MazKid points out, the complexity.

I think the Mazda systems were electronic, weren't they? It actually made quite a difference to the old 4 cylinder turbo MX-6 - calmed the torque steer right down.
 
The MX-6 and 626 system was electronic...2nd gen RX-7s have a manuel type of it. And, to be honest, it doesn't make sense how the RX system works...I guess it's friction with the road or something, but if you think about it, that would be wierd. And it only works at higher speeds(could be inertia?). I've noticed it once or twice in my dad's RX-7.
 
That's pretty slick. I didn't know anyone was doing this in production. It seems like there could be a pretty steep learning curve for the weaker minded motorers. I mean, having a car react more accurately instead of having to whip the wheel around to get it to go where you want.
 
MazKid: are you sure that youre not talking about the automatically adusting suspension (AAS) on the 2nd gen rx-7's? When the switch is turned on, the rear suspension automatically adjustusts rear camber to allow for better cornering, but if there is an aws system for my baby, please tell me more about it. Maybe a link to a site w/ information about it. thanks
 
It sounds similar to a thing Peugeots had a few years ago where a steering effect was given on the outside rear wheel as the suspension loaded up.

The only vehicle with it currently, is the GMC truck.

I am angry over this. General Motors wanted to distance GMC and Chevrolet, so they decided to give GMC ONLY a 4-wheel steering truck. Then it starts making money. So what does Chevrolet immediately do? Produce their own 4-wheel steering truck. Damn money-grubbing freaks.
 
Alikax, no it's not that. Only certain trim levels of the RX had AAS, not my dad's(his is an '86 base(with the luxury package)).

This is like what Vat said. I'll look into it and post back here.
 
From a performance standpoint, too much of a rear steering angle would be dangerous, wouldnt it? I assumed the trucks' systems were primarily for parking and other low-speed maneuvers.
 
The GMC system is for all speeds, like explained above. It's safer with a higher rear steer angle because the truck is long.
 
cool. Any info onthe RX-7 AWS system yet MazKid? I've been doing my own searching @ my usual fc sites but to no avail are you sure it exists?
 
Nissan's HICAS system worked the same: low-speed/higher-angle/opposite-dir for parking lot maneuvers, high-speed/lower-angle/same-dir for lane changes. Often avoided or removed by educated Nissan geeks due to unpredictable handling.
 
My brother's a Prelude geek, and I wanna hear someone else's opinions on the relative merits of Honda's ATTS system vs straight-up LSD. Anyone?
