How does four-wheel steering work?

What's up with cars that steer from the rear? How does four-wheel steering work, and why is it useful? Allow me to show you, using the all-new Mercedes-Benz S-Class and it's wild 4WS system as a perfect example of this agility-boosting technology!

I just found this video and decided I’d sub, i thought you were some well known high sub mechanic channel or something, my mind was blown when I saw only 500 subs??? You should have over 50k with this video quality!

Mercedes was actually the first with rear wheel steering. The 1938 Mercedes Gelandewagen had it.

i always liked four wheel steering because of speed racer

[@ahmedeldeeb7192]

very helpful thanks

[@Instamatic898]

You're welcome mate!

[@taz_7766]

Whaaaa, such angle

[@50yearoldskier]

Great video. Do you think the RAS is worth it?

[@Instamatic898]

For something as big as an S-Class, I'd say it's absolutely useful. It's technology that also tends to find its way into performance cars as well, but for that kind of thing I think its value is dubious.

@@Instamatic898 thank you Tony!! I am of the same mindset. I just don't think I need this functionality for daily driving in the suburbs!!

[@orchidssarorchids2673]

Good for long chassis

[@JLCRobotics-PhilDenton]

I love a good potty trick!

[@ramiabram6010]

Will this be available in the eqs or is it only for s class

[@LouisChiaki]

Do you still need to do wheel alignment?

[@Instamatic898]

I pity whoever has to perform a wheel alignment on this thing.

i need your script for my college discussion

[@ravigautam8685]

how does engine engage with the wheels after all the wheels have been steered.

[@yung-megafone]

Similar system to a front wheel drive vehicle, they have u-joints that can flex while still transmitting power from the engine.
Hope this answers your question unless I misread that and you intended something else

[@Star_Link-89]

honda prelude same like that

[@ysph]

nice slurp sound effect. that's weird as hell though.

[@Instamatic898]

I'm just glad somebody noticed :p

*laughs in Nissan ATTESA*

[@Instamatic898]

The chad S-Class laughs at the puny 1-deg articulation of the virgin HICAS.

[@elementle]

@@Instamatic898 I jest, this is a seriously impressive bit of kit. That slalom footage is mind-bending!

Nice parking...then you can't open the door.
