October 6, 1955, Paris Motor Show. Visitors stroll leisurely between the stands, stopping in front of a Peugeot 403 here, a Renault Dauphine there, when suddenly... BAM . At the Citroën stand, there's a riot. Literally. People jostle, step on each other, some even climb onto the barriers to get a better look. What could possibly cause such mass hysteria? A car. But not just any car.
A car that looks like a spaceship, with shapes that defy all the laws of the automobile as we know it. A car so revolutionary that 743 people sign an order form in the first 15 minutes . I swear, 15 minutes! It takes me longer than that to choose my Friday night pizza.

This car is the Citroën DS 19 , and I'm going to tell you how three men created the most futuristic vehicle in automotive history. A story of genius, technological revolution, and a car that literally saved General de Gaulle's life. Sit back, because we're going to travel back in time, to the time when France still drove on cobblestones and having suspension that didn't break your back was the stuff of science fiction.
The trio of geniuses who revolutionized the automobile
It all began in the early 1950s, in the Citroën design offices. Pierre-Jules Boulanger , the brand's visionary boss, had a crazy idea: to create a car that would be to the automobile what the Concorde would later be to aviation. An object of the future, but for the present.
To carry out this pharaonic project, he brought together three men with completely different profiles but whose talents complemented each other perfectly.
André Lefèbvre: The engineer of the impossible
First, there's André Lefèbvre , an aeronautical engineer who worked on airplanes before joining Citroën. This guy thinks in terms of aerodynamics, lightness, and technical revolution. For him, a car should cut through the air like an airplane, not roll like a tank. His obsession? Compensating for engine weaknesses through weight savings and aerodynamics .
Lefèbvre was the technical mastermind of the project. He wanted front-wheel drive, optimized weight distribution, and above all, he wanted this car to be able to drive fast on the rotten roads of the time. Because yes, in the 1950s, France didn't yet have its highways. We drove on rutted departmental roads, and traveling meant accepting being shaken like a cocktail.
Flaminio Bertoni: The sculptor of the automobile
Then there's Flaminio Bertoni , an Italian sculptor who's been working at Citroën since 1932. He's not an engineer, he's an artist. And it shows! The guy designs cars like others sculpt statues. For him, a car must be beautiful before it can be practical.
Bertoni had a completely unique approach: he sculpted his ideas in plasticine, then in blocks of plaster. And wait for it, it was a fish that would inspire him to create the lines of the DS . One Sunday morning in 1953, he carved the almost definitive shape of the future DS19 into a block of plaster. Just like that, instinctively, based on the fluid movements of a fish in water.
Paul Magès: The magician of hydraulics
And finally, there is Paul Magès , the most discreet but perhaps the most brilliant of the three. This guy is a pure autodidact, having joined Citroën at 17 as a simple worker. But he has a gift for mechanics that borders on the supernatural. He is the one who will revolutionize automotive hydraulics .
Magès is developing a hydraulic system of incredible complexity that will control the suspension, power steering, clutch, AND brakes. All this with a pressure of 17.2 MPa. To give you an idea, that's 172 times atmospheric pressure. Unheard of in the automotive industry.

October 6, 1955: The day the automobile entered the future
So, let's go back to that famous October 6, 1955. The DS is unveiled to the public , and it's the apocalypse. Not in the sense of catastrophe, but in the sense of revelation. People can't believe their eyes.
Picture the scene: you're in 1955, driving a 2CV or a 4CV, small, straight rectangular boxes, and suddenly you're shown this. A car with no visible grille, with fluid lines that seem to flow like water, headlights hidden behind small hatches . It's as if someone had opened a window onto the year 2000.
And I'm not even talking about the technical innovations yet! We discover that this car raises and lowers itself, that it remains perfectly stable even when you remove a wheel, that it has disc brakes when everyone else is still driving with drums...
12,000 orders on the first day . Twelve thousand! By the end of the show, they had 80,000 signed order forms. A record that wouldn't be beaten until 60 years later by the Tesla Model 3. And yet, Tesla had the internet to create a buzz. They only had word of mouth and newspapers.
The technical revolution hidden beneath the beauty
But hey, a beautiful body is all well and good, but what really makes the DS revolutionary is what's underneath. And here, my friends, brace yourself because we're entering science fiction.
First crazy thing: the hydropneumatic suspension . Forget everything you know about conventional suspensions with their springs and shock absorbers. The DS works with pressurized oil and nitrogen-filled spheres. The result? Crazy handling combined with comfort that was compared at the time to a "magic carpet."
I remember the first time I drove a restored DS. It was a few years ago, a collector friend offered me a little ride. Well, even today, with our modern cars full of electronics, the feeling of comfort of this suspension remains astounding . It feels like you're floating above the road.
Second crazy innovation: disc brakes . In 1955, this was unheard of on a production car. Everyone still drove with drum brakes that overheated, tired, and were dangerous under intensive use. The DS, on the other hand, stopped like an airplane.
