Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
I swear Doug started cars and bids just so he could get his hands on all these quirky cars 😂
I'm not sure of the Citroen CX is capable of doing this, but other Citroen models with the hydropneumatic suspension are so balanced that they can drive on 3 wheels. You also can raise the suspension, put a jackstand under a corner, and lower the suspension so you can change a flat tire without using a jack.
The hydropneumatic suspension is also tied into the steering. That's why it's able to automatically returns to center. Like /u/hittar said, the front wheels aren't mechanically connected to the steering wheel. It's kinda like how heavy machinery is steered. It's all hydraulic.
I also believe that the brakes in this car are tied into the suspension too. In the Citroen DS, you didn't get a brake pedal but a brake button. It was like an oversized carburetor priming bulb that you'd find on a lawnmower. The brakes were totally controlled by pressure and not by travel. The button didn't push in like a brake pedal. Instead it would always stay firm and how hard you were pressing the button would correlate to how hard the brakes were clamping down.
The control stick in the first run of F-16 fighter jets was the same way and most pilots hated it. A lot of people hated Citroen's brake button too. General Dynamics later added in some movement to the f-16's stick and Citroen went back to a brake pedal.
As a resident Citroen nut I feel obligated to add some information. There are a couple things Doug missed about this car.
Firstly, the whole hydraulic system is driven by the same pump. Brakes, steering assist and suspension are all one and the same. It gives this car a couple of pretty incredible, at least for its time, benefits. It has fully variable steering with smooth increase of weight with speed and it stays completely flat when you brake - suspension valves and brakes are controlled by one distributor (which is one hell of a thing to fix), which does not let it dip while braking.
Secondly, the steering. This system is called Diravi, and it’s insane. Self centering is only a tip of an iceberg. There is no direct connection to the wheels except for a little emergency pin, it is driven by hydraulic pressure. The steering is not “power assisted”, steering wheel is completely detached from the wheels themselves. Doug said that steering feel is not very precise - well, it’s because there is no feel. It’s completely artificial, you can’t feel anything because there is nothing to feel. It’s almost impossible to turn the wheels when the engine is not running, and in case of a system malfunction you are supposed to stop as soon as possible and get a tow truck. There are benefits to this system too - as I said earlier, it’s fully variable with smooth change in weight across all speeds and it ranges from super light to very heavy all the way from 0 kph to 200kph. It is also very stable with no regard to quality of road surface, and you won’t lose control in an event of a blowout.
In general though, hydraulics in this car are pretty reliable and not that expensive to maintain, at least in Europe, but getting some parts can be a real problem.
Aaaah, I've been waiting for that video ever since he mentioned he had some 80's Citroën for us on another Reddit thread.
I'd like to add a few things:
"These aren't the original cupholders, but they are designed for this car" - Literally a 2x4 with duct tape stuck into the center console.
Almost had a heart attack when I saw the title of this video...
Hey Doug, any chance you'd want to review my 20k mile 94 Citroen ZX Furio? It's got some very Doug-friendly 90s-French-car quirks.
In the suspensions highest position it looks like an AMC Eagle or an early French crossover.
Now this video is right up my alley! Great job keeping your channel interesting and varied, /u/Doug-DeMuro! It's because you cover cars like this one that I'm subscribed to your channel.
Some additional information: The idea behind the single-spoke wheel is that it's safer: The end of the steering column is further away from your chest. This design comes from a time before widespread seat belt use. If you're not restrained by a belt, your entire body will move forward during a frontal collision and your chest will impact the center of the wheel instead of your head (which will impact the top of the rim). By angling the center back and making the rim of the wheel collapsible, your chest and head are a bit better protected. This works less well with a seatbelt, of course, but you have to remember that even when this car was new in the mid '80s, only a minority of all drivers used seat belts in the first place.
The self-centering aspect of the steering wheel is not just a result of the car's hydraulics, but also an intentional safety feature that the CX inherited from the DS: The idea is that if you're at a stoplight and you experience the misfortune of being rear-ended by another car, you don't get pushed into oncoming traffic, because the steering wheel will be centered and thus the car will roll straight ahead instead.
The concave rear window has this shape in order to be self-cleaning and not needing a wiper, which reportedly works quite well.
As for the handling, the hydropneumatic suspension was not desigend for this at the time, but Citroën absolutely perfected it with a later model, the Xantia and its range-topping Activa:

This system worked so well that the car kept beating far more expensive supercars at slalom and moose tests long after it had been discontinued:

Who would have thought that a slightly upmarket Citroën would handle better than a Porsche 997 GT3?
That spare tire placement.. What were they thinking.
