It's the early 1940s, France is occupied, and in a discreet office of the Renault factory, engineers are literally risking their lives to design a small yellow car. A car that will revolutionize the French automobile industry and that will be nicknamed "the lump of butter." And when I tell you that they were risking their lives, it's not a figure of speech - developing a new car under German occupation was strictly forbidden.
Yet, this little rebel would become the first French car to exceed a million units, transform a Buchenwald survivor into a visionary leader, and even piss off Ferdinand Porsche to the point that he ended up in prison. Today, I'm telling you the story of the Renault 4CV.

The clandestine conception (1941-1944)
Picture the scene: It's 1941, France is under German rule, and Wilhelm von Urach, the German administrator who controls Renault, has been very clear: no new passenger cars are to be developed. Period. But in the Billancourt design office, two engineers decide to play with fire: Fernand Picard and Charles-Edmond Serre.
These two have a crazy idea: to secretly design a small, popular car for the post-war period. The project is codenamed "106E" and I swear it's resistance-level . Sometimes they even hide their plans from Louis Renault himself, for fear that he'll spill everything to the Germans out of opportunism or coercion.
And then one day, disaster strikes. Von Urach sees a green prototype drive by in the factory courtyard. He questions Fernand Picard, who, without blinking, lies to his face. "A new car? What new car?" That same evening, Picard has the prototype repainted black to cover up the traces. Pure composure .
For three years, they developed their baby in the shadows, hiding the plans, disguising the prototypes, and praying that their secret would never be discovered. Because beyond their project, it was their lives that were at stake.
The arrival of Pierre Lefaucheux - The resistance fighter who will change everything
1944, the Liberation finally arrives. Louis Renault is arrested for collaboration and dies in detention. The French state nationalizes the company and looks for someone to lead it. And there, they call upon an extraordinary man: Pierre Lefaucheux.
This man, I have to tell you his story because it's crazy. A resistance fighter from the very beginning , Lefaucheux was arrested by the Gestapo in June 1944 and deported to Buchenwald. Normally, his story ends there. Except that his wife, Marie-Hélène, hasn't said her last word.
This woman has balls of steel. She shows up at a Gestapo officer's house in Nancy and manages—I don't know how—to convince him of her husband's innocence. And you know what she does? She takes him by car to the camp to get Pierre released. Can you imagine? She drives to Buchenwald with a German officer to get her husband back. It's unprecedented.
Lefaucheux thus emerged alive from hell and in 1945 became the first CEO of Régie Renault. The man who would transform a ruined company into an industrial giant. And his first mission? To examine the famous "106E" project, which the engineers had kept secret during the occupation.
When Lefaucheux discovered the plans for the small car, he immediately understood its potential. This 4CV was exactly what France needed: a simple, robust, and affordable car to power the masses. He gave the green light and set an ambitious goal: 300 cars per day by 1949.
The birth of "the lump of butter"
1947, production finally begins. And then comes the first problem: what color should these cars be painted? The answer will give rise to the most famous nickname in French automobiles.
As war reparations, Renault recovered a stock of sand-yellow paint that was used to paint the tanks of Rommel's Afrika Korps. No choice , we used what we had! Result: the first 4CVs left the factory in this particular shade which, combined with the car's rounded shape, immediately earned it the nickname "butterball".
And you know what? This nickname would stick to the 4CV throughout its career. The French loved this little round yellow thing that stood out from the imposing pre-war cars. It was cute, accessible, and above all, it represented the hope of the post-war era.
But beyond its attractive looks, the 4CV concealed a technical revolution. Pierre Bézier—yes, the man of mathematical curves—designed the first automated transfer machines for Renault. Renault became the first French manufacturer to adopt Ford's assembly-line production methods. It was this modernization that would make it possible to achieve the production targets set by Lefaucheux.

The Ferdinand Porsche Affair - When Ego Causes Damage
In 1945, the French government came up with what it thought was a brilliant idea: to call on Ferdinand Porsche, the creator of the Volkswagen Beetle, to give his opinion on the 4CV. The idea was to ensure that the little French car could compete with the German.
Except that Pierre Lefaucheux is furious . For him, bringing in Porsche is implying that the 4CV is inspired by the Beetle. However, the 4CV was designed in parallel, by the French, in complete secrecy. This is an insult to the work of his engineers.
The meetings take place, Porsche examines the car, gives some technical advice. But as soon as the political obligations are over, surprise! Ferdinand Porsche is arrested for war crimes and sent to Dijon prison where he will spend 20 months without trial .
I'm not saying Lefaucheux had anything to do with it, but hey... let's just say the matter was settled in a very French way. "You want to compare my car to a Volkswagen? Fine, but you'll end your stay in France behind bars."
This small car, born of the Resistance, represented much more than a simple means of transportation: it embodied the rebirth of French industry. And incidentally, it would prove itself a far cry from its German rival.
The phenomenal success
From 1947 onwards, it was a boom. The 4CV enjoyed a success that no one had anticipated. The French, deprived of cars for years, literally rushed to buy this small car which cost three times less than a Citroën Traction.
I have to tell you, at the time, owning a car was still a privilege. But the 4CV changed everything. For the first time, working-class families could afford a car. Teachers, employees, and small business owners discovered freedom of movement.
And the numbers speak for themselves: in 1961, when production ended, 1,105,547 units had been built. The 4CV became the first French car to exceed one million units. An absolutely incredible record for the time.
But what fascinates me most is that this popular little car will also cover itself in glory in competition. Because yes, the butter pat, it had character!
Sporting achievements - When the lump of butter puts on a show
1950, 24 Hours of Le Mans. A small, modified 4CV takes the start alongside the giants of the time. And you know what happens? It finishes 17th overall . A small car weighing 760 kg with a 21 horsepower engine that can keep up with the racing cars!
The following year, at the Monte Carlo Rally, a 4CV R1063 version won its category. Monte Carlo! Can you imagine? This little thing that was used to take kids to school found itself on the roads of Monaco, battling against far more powerful cars.
And this is where the story gets even more beautiful. A certain Jean Rédélé, a motorsport enthusiast, took the chassis of the 4CV R1063 to create his famous A106 coach. This A106 coach is nothing more and nothing less than the first Alpine in history . Yes, the legendary Alpines, the ones that would dominate world rallying for decades, are directly descended from our little lump of butter.
That's what I like about this story: this car designed for the average Joe will spawn a line of exceptional sports cars. It just goes to show that sometimes all it takes is a good foundation to work miracles.
Remember when the R5 was more than just a people's car—it was a symbol of freedom and independence for a whole generation of French people? Well, the 4CV was no different 30 years earlier. When it was released in 1947, no one imagined it would become one of France's most iconic cars.
And you know what? This 4CV reminds me why I love miniature cars. Because holding a small 1/43 scale 4CV in your hands is a bit like experiencing that whole era all at once. The hope of the post-war period, French ingenuity, that period when everything had to be rebuilt.
That's why I opened my shop BernardMiniatures.fr. I have more than 1500 miniatures in stock, mostly 1/43 scale, with a focus on vintage cars from the 1950s to 1999. Well, I'm not a big site, so I often only have one or two pieces of each model, but that's also what makes it charming. I have some beautiful 4CVs of course, but also Dauphines, R8s, 2CVs, rally cars... a bit of everything.
Shipping is free for orders over €75 in France, and I make sure to wrap everything well with bubble wrap because these little cars break easily. Go take a look at bernardminiatures.fr if you're interested - and you'll see, I have some miniature 4CVs that are really worth a look.
Now, let's talk a little more about the global expansion of this little revolutionary...
International Expansion - The French Touch Conquers the World
The 4CV's success wasn't limited to France. As early as 1953, Renault signed an agreement with Japanese manufacturer Hino to assemble the 4CV under license in Japan. A world first for Renault! Imagine: small French cars assembled in the Land of the Rising Sun until 1963.
But the craziest thing is the American adventure. Around 170,000 units will be exported to the United States. So, you have to look at the picture: our little 3.50-meter-long 4CVs are arriving on American roads amidst giant Cadillacs and oversized Chevrolets.
Well, I can assure you, it wasn't a huge success. Americans found the 4CV a bit... how can I put this... ridiculous . Too small, not powerful enough, not flashy enough. But there were diehards who loved this economical and easy-to-handle little French car.
And then, the 4CV seduced a few celebrities. Jean Gabin, for example, was crazy about his 4CV. He loved its robustness and its "not boring" side. Pierre Mendès France, when he was Prime Minister, used a 4CV for his official travels. Imagine the symbol : the head of the French government driving a small people's car rather than a large official sedan.
That was the 4CV spirit. A car that erased social differences, made mobility accessible to all, and perfectly embodied the spirit of post-war reconstruction.
The end of an era
In 1961, after 14 years of loyal service, production of the 4CV ended. It passed the baton to its worthy successor: the Dauphine. But between you and me, the Dauphine would never have the charm or the aura of its little sister.
Because you see, the 4CV was more than just a car. It was the symbol of an era, of a country rising from the ashes, of French engineers who had achieved the impossible: secretly designing, under occupation, the car that would power France.
This little lump of yellow butter had succeeded where many had failed. It had democratized the automobile, proven that France knew how to produce industrial volume, and even been a hit in competition. Not bad for a car born in secret , right?
And today, when I see a 4CV in the street - because there are still a few of them running - I think back to that incredible era. I think of Fernand Picard who lied to the Germans, of Pierre Lefaucheux who transformed a ruined company into an industrial giant, of all those French people who discovered automotive freedom thanks to this little rebel.

The legacy of a legend
Sixty years after its production ended, the 4CV remains in the hearts of the French. It represents that blessed period when French industry innovated, when our engineers performed miracles with next to nothing, when a small car designed by resistance fighters could conquer the world.
Because in the end, that's the story of the 4CV: the story of the French resistance that doesn't end with the Liberation. It's the story of men and women who continued to fight, no longer against the occupier, but to rebuild their country and restore its place in the concert of industrial nations.
This little lump of butter carried within it all the hope of the post-war era. And frankly, mission accomplished. With over a million units sold, racing victories, and a prestigious racing lineage with Alpine, it's safe to say that the little rebel from Billancourt has more than lived up to its promise.
So the next time you come across a 4CV, whether real or miniature, think of this incredible story. Think of the courageous engineers who risked their lives to design a car, the resistance fighter who left Buchenwald and transformed Renault, and all the French people who discovered freedom behind the wheel of their little lump of yellow butter.
Because ultimately, the 4CV's greatest story is perhaps this: having proven that with courage, ingenuity, and a little nerve, you can transform a clandestine project into an industrial revolution. Not bad for a small car born in the shadows, right?
