LOL. Ever park next to something with a articulated loader, then need to turn to get away from it?

'Crab' is when the rears and fronts steer at the same angle...called 'pro'

'Con' is when the rears go the opposite steering angle

I am sure that Ford could come to market with this without patent issues. Quadsteer was designed in the late 90's early 2Ks and went to market in the mid 2Ks. I am sure they have come up with a way to do it now that doesn't step on any patient by Delphi. I think there is a time limit on it anyway. It could be a benefit, if like frequently mentioned, it can be done at a reasonable price, and is robust it would likely sell. I will say putting in a SD tells me that Ford feels pretty comfortable in its durability.

Maybe Ford is getting ready to haul the tons of batteries needed for an electric truck and they want to use all the wheels to get that mass to turn.

I came across this article that helps explain why the GM system didn't sell well.

"GM's Quadrasteer setup was very costly in its first couple of years. It cost as much as $7,485 in 2002. It was also expensive to make, expensive to repair, and unreliable."

$7,485 was a lot of money for an option.

I suspect that another factor was very few dealers putting them on the lots and fewer customers like doing special orders. I see that with Ford's Max payload package for the F150.

I hope that Ford learns from that failure and makes the next statement in the article come true:
"Almost two decades of automotive engineer advancements should make Ford's system cheaper and more reliable."
Plus, the Ford in the diagram has flaired fenders which should allow for increased steering angles on the rear axle.

Some background on GM's quadrasteer failed

Ford recently filed for a patent on for 4 wheel steering and really surprised me is that the patent implies that it will for the Super D Duty series.

Ford patent

I don't know what makes this patentable since GM had 4 wheel steering 18 years ago and others have been demonstrating 4 wheel steering recently. Hopefully the differences improve cost and reliability. I like the concept but definitely want to know the costs before purchasing one.

Well the first as I know 4 wheel and 4 wheel steer vehicle anywhere was the Australian Caldwell Vale Truck of 1907

The company started in 1907 when Felix Caldwell and Norman Laurie Caldwell of South Australiafiled for a patent covering "Improvements in and connected with driving and steering motor propelled vehicles". In short, the patent was for a four-wheel-drive system with four-wheel-steering. Later they combined with Henry Vale of New South Wales and in 1910, the trio applied for a patent covering "Improved power steering gear for heavy motor driven road vehicles".

I worked at a Honda dealer back in 1989-90.

4-wheel steer Preludes were a blast to drive.

I hope Ford does have something up their sleeve.
