Why not.

Stuck on a tight track. Just do an on the spot circle rather than a 20 point turn :)

I guess its just more extreme 'rear wheel steering' which has been around for ages.
I would not think this is a huge engineering challenge and would be great for offroaders, as it is already for some specialist large trucks and racing buggies.

But its not been done in 4wd cars because it adds complexity/cost.

There was this.

4 wheel steering had a 'popular' period in the 90's. I remember one review stating that similar or better results could be achieved by just making the car lighter. I think that was in reference to a Honda.

On fourby it would allow bigger vehicles to negotiate some tighter tracks.

Would like to see how those complicated mechanisms on a 4WD hold up on 100's of kilometres of corrugated dirt roads and water crossings. Me thinks it would be super expensive to maintain/repair.

Though, being a Toyota, it's almost got that way that if you can afford one in the first instance, then maintenance and insurance shouldn't be a consideration! (Maybe they'll even throw in another cup holder just for the shits-and-giggles of it) ;)

Lots of extra stuff to fit around the rear axle(s) and safety considerations, especially if its all electronically controlled which I guess it would be (instread of physical linkage to the steering column)

Engineering for engineering's sake?
How many features that are demonstrated on concept cars never make it to production?
I'd put money down that the engineers will take it to the accountants and get told No, long before the production line tools up. If it adds a few thousand to the final cost and makes them slightly less competitive price wise and increases the risk of getting a poor name for reliability, then they will have a hard time getting it over the line.

Its a pity. A lot of stuff does not get past a prototype because of the dollar.
But with all new products and electric wheel-based motors this might just happen.
Good on Toyota for taking the lead on something, unusually ;)

But have they "taken the lead"? Or are they just the first to press with the idea?
I can see potential for the idea in commuter vehicles, not so much in traditional off roaders

I'd like to suggest that it would make parking easier but I'm sure there would be people who will still find a way to completely stuff it up.

As a birthday gift, was given a ticket to drive a 4 wheel steer/drive at a track at Lara, near Geelong, I recommend it!
The vehicle was a shorty V8 Toyota, will ask the Mrs the name of the Company and post it
It took me an hour to master the steering, the front being by steering wheel, the rear by a lever next to the hand brake. As you can imagine it was hard to get co ordinated but once you did, there was no stopping it
In the finish it was easier to steer it by the rear wheels and leave the front pointing forward
Its advantages were
the turning circle, it turns in its own length, the biggest advantage being the ability to crab walk side ways to line up square on to climbs and even up the climbs
This would put your 4 x 4 in a different class if doing steep, rock laden tracks etc, but if you are only sticking to unmade roads then it would be definitely over the top
Would i buy one if Ford made them for the Ranger, sure would
ps, why does my the type keep changing???? :(
