In the high-octane world of Formula 1, legends are often forged in the fires of passion and raw aggression. We remember the drivers who wore their hearts on their sleeves, those whose emotions spilled over at every turn. But Alain Prost was different. Known globally as “The Professor,” Prost didn’t race with his heart; he raced with a cold, calculating mind. For over a decade, his presence in the paddock made rivals uneasy not because he was explosive, but because he was precise. He was the man who turned racing into a game of chess at 200 miles per hour.

Now, at 70 years old, the four-time World Champion is looking back at a legacy that is defined as much by his internal conflicts as his statistics. While the trophies gather dust, the names of those he stood against remain etched in his memory. Behind the strategic genius lay a darker reality: a career built on silent wars, garage-room hostilities, and political battles. Here are the five people Alain Prost truly could not tolerate—the rivals who forced him to confront the version of Formula 1 he fundamentally rejected.

1. Ayrton Senna: The Philosophical Collision

The rivalry between Alain Prost and Ayrton Senna is arguably the greatest in the history of sports, but for Prost, it was never just about who was faster. It was a clash of philosophies. When Senna joined McLaren, he brought a spiritual, almost reckless belief that racing was a moral battlefield. Prost, the established leader, viewed racing through the lens of risk management and discipline.

To Prost, Senna’s “win at all costs” mentality was dangerous and irresponsible. The tension famously boiled over at Suzuka during their most intense title fights. While the world saw two titans fighting for glory, Prost saw a man willing to use destruction as a tool for victory. He didn’t hate Senna for his talent; he hated what Senna represented: the idea that winning justified anything. For Prost, the deliberate collisions were a line that could never be erased. It was a rejection of the intelligence and responsibility Prost spent his life championing.

2. Nigel Mansell: The War of Egos

If Senna was an ideological enemy, Nigel Mansell was a deeply personal one. Their conflict reached its zenith at Ferrari, a team already drowning in its own internal politics. Mansell was the “Lion,” the emotional hero of the fans who drove with visible passion. Prost was the clinical technician who wanted structure.

Inside Ferrari, the garage became a battlefield. Mansell felt the team favored Prost, while Prost viewed Mansell as an undisciplined driver who relied too heavily on raw emotion. In the world of “The Professor,” nothing was more frustrating than a teammate who pushed a car past its limits and ended up in the garage while points were on the line. There was no dramatic single moment for these two; instead, it was a slow burn of vanished cooperation and cold interviews. For Prost, Mansell was a rival he could never trust, and in his world, a lack of trust was far worse than a lack of speed.

3. Nelson Piquet: The Cold War of Intellect

Nelson Piquet was perhaps the only driver who could match Prost’s intellectual approach to racing, but he used that intellect as a weapon of provocation. Both were masters of tire management and race strategy, yet their personal relationship was toxic.

Prost valued control and professionalism; Piquet valued disruption and sarcasm. Piquet frequently mocked Prost in the media, questioning his courage and downplaying his achievements. To Prost, this wasn’t psychological warfare; it was noise that undermined the credibility of the sport. What made Piquet intolerable was his unpredictability. Prost wanted a predictable environment where the smartest man won; Piquet wanted chaos. Their rivalry lived in the whispers of the paddock, a silent acknowledgement that while they were equals in brilliance, they were worlds apart in character.

4. Ferrari: The Betrayal of a Broken System

For Alain Prost, some enemies didn’t wear racing suits—they wore ties. His move to Ferrari was supposed to be a match made in heaven, but it quickly turned into a slow-motion disaster. Prost joined to bring discipline to the Scuderia, but he found a system governed by national pride and power struggles rather than performance.

Despite fighting for the championship, Prost felt his technical feedback was ignored. The relationship disintegrated when Prost, in a moment of brutal honesty, compared the Ferrari car to a “truck.” The team didn’t respond with improvements; they responded with war. Ferrari fired the four-time champion before the season even ended, a public humiliation that Prost viewed as the ultimate betrayal. He didn’t hate losing to a better car, but he loathed losing to a broken system. Ferrari wasn’t just a team; it was a structure he couldn’t fix, and for a man of logic, that was intolerable.

5. Jean-Marie Balestre: The Shadow of Power

Finally, there was Jean-Marie Balestre, the President of the FIA. Unlike the other rivals, Balestre wasn’t someone Prost could out-brake on the track. He represented power without a steering wheel. While critics often painted Prost as Balestre’s “pet” or political ally, the reality was much more uncomfortable for the driver.

Prost wanted clear rules and fairness; Balestre wanted authority and influence. The controversial decisions at Suzuka, where the FIA intervened in ways that changed the course of history, haunted Prost’s legacy. It made his victories look like political executions rather than sporting achievements. Prost despised being associated with the dark arts of F1 politics. He knew he could defeat any driver, but he could never defeat the structure Balestre controlled. Balestre was the constant reminder that in Formula 1, championships are often decided in offices, not on the asphalt.

Alain Prost was never the most “loved” champion, but he was undeniably the most intelligent. His career teaches us that in a sport ruled by ego and emotion, thinking differently comes at a heavy price. He didn’t seek out these enemies for spectacle; he stood against them for principle. Today, his reflections offer a rare, unvarnished look at the cost of greatness and the high stakes of a life lived at the limit.
