In the spring of 1959, Guy Grosset-Grange, a newly graduated Arts et Métiers engineer, arrived at the Renault offices with a revolutionary idea that would send management into a frenzy. This 28-year-old wanted to overturn 50 years of French automotive tradition by putting the drive wheels at the front of a utility vehicle. Opposite him was Fernand Picard, director of research and father of the legendary 4CV, who considered this idea a technical heresy. "Mr. Grosset-Grange, at Renault, we put the engine at the rear, period!"
But what Fernand Picard doesn't yet know is that this generational conflict will give birth to the Renault Estafette , the utility vehicle that will revolutionize French transport and lay the foundations for Renault's modern DNA. A story of rebels, innovation and a few million kilometers in the African desert to prove that sometimes, you have to know how to say no to your elders.
{slides}I have to confess something to you: when I was a kid, I loved watching the little blue gendarmerie Estafettes drive through my village. Those forward-facing cabs with their flat noses had something futuristic about them for the time. And then later, when I started to take a serious interest in automotive history, I discovered that behind that very particular silhouette lay a true technical revolution.
The rebellion of Guy Grosset-Grange
Let's go back to 1957. Guy Grosset-Grange , nicknamed "GGG" in the corridors of Billancourt, has just been appointed head of the "new utility vehicle" project. The specifications are simple: Renault wants a practical vehicle to compete with the Citroën HY and other Peugeot D3As which dominate the utility market.
But GGG has a different vision. Where everyone else envisions a classic vehicle with a rear engine, as Renault tradition dictates, he envisions a revolutionary architecture : engine and transmission at the front, cab as far forward as possible, and optimized cargo space. Essentially, he wants to do the exact opposite of what Renault has been doing for decades.
The problem is that facing him is Fernand Picard , a living legend at Renault. This man created the 4CV, the model that relaunched the brand after the war. For him, the Renault philosophy is "everything in the rear": engine, transmission, all that must be behind the passengers. Period.
Imagine the tension in the meetings! On one side, the young wolf who wants to revolutionize the French automobile industry, on the other, the patriarch who defends 50 years of know-how. GGG doesn't give up . He multiplies studies, calculations, technical arguments. Front-wheel drive would allow for a flat floor, a low loading sill, better weight distribution...
Fernand Picard remains adamant. "We're not going to copy the Germans with their Volkswagen!" But GGG has an ace up his sleeve: he'll prove by example that his vision is the right one.
The desert trial
To convince the skeptics, GGG is proposing something new for Renault: an endurance test worthy of a rally-raid . The Estafette prototypes will be subjected to more than 2 million kilometers of testing, in the most extreme conditions possible.
And then, it's total madness! Renault engineers take their prototypes to Africa. Desert, infernal heat, rutted tracks, maximum load... it's all there. But the craziest thing is that they even test their 845 cc engine on a German Gutbrod Atlas utility vehicle that normally carried 1000 kg with only 622 cc!
Can you imagine the scene? French engineers grafting their engine onto a German chassis in the middle of the African desert to prove that their little mill would hold up. It was a time when people weren't afraid to get their hands dirty!
Browse our selection of over 1,500 models. Browse through our various categories: French cars, foreign cars, sports & racing cars, professional vehicles, and vintage vehicles.
The results are spectacular. Not only does the engine hold up, but the front-wheel drive also reveals all its advantages on difficult terrain. Better traction, more predictable behavior, ease of driving... GGG has finally proven itself.
