Year 2000, Button vs Junqueira and the race seat…
An untold story of how Williams suddenly had to choose a driver, and did it in a way nobody else ever had…
Jenson Button was barely more than a name whispered in junior racing circles; he had not even taken the usual route through Formula 3000, like any other F1 driver at the time, but somehow, he found himself at the center of one of the most unusual and quietly intense driver shoot-outs F1 had seen in years.
The prize was enormous; a race seat at Williams F1 team.
Ralf Schumacher secured the seat, with factory backing from BMW.
The pressure for Jenson Button was immediate, the expectations even higher; and standing directly in his way was a driver who, on paper, looked far more ready for the job.
Button vs Junqueira: The Barcelona Shoot-Out
According to reports, the test took place at the Barcelona circuit in January 2000.
On one side was Jenson Button, just 20 years old, fast, and largely unproven at that level.
On the other hand was Bruno Janqueira; the reigning Formula 3000 champion, experienced, and already trusted by many within the Willians garage.
What makes it even more interesting is that this was not a casual evaluation, it was a direct comparison, same machinery, same conditions, and the exact same opportunity to prove who truly deserved the seat.
Over longer runs, roughly 20 to 30 laps; Button edged it, not by a huge margin, just 0.16 seconds, but enough to turn heads.
It wasn’t dominance, it was something more subtle; there was rhythm in his driving, a kind of calm speed that didn’t look forced, even more impressive, he was doing it at a circuit he barely knew.
Engineers vs Instinct
Reports suggest that at the Williams team, engineering group leaned toward the Formula 3000 champion Bruno Janqueira.

They believed that he had experience, he understood car setup in greater depth, and could communicate technical feedback with clarity.
Bruno Junqueira even reinforced that advantage during an unusual part of the evaluation; both drivers were given a written engineering test, something that felt almost ouf of place in a F1 shoot-out.
Sitting in what was essentially a car park environment, they were asked to demonstrate their technical understanding; here, Junqueira stood out, his background in Formula 3000 showed, he knew how to approach setup questions, how to think like an engineer as much as a driver.
So for a moment, it looked like the decision was tilting firmly in his favor, but F1 decisions aren’t always made on paper!

Frank Williams Changes His Mind
At the center of it all was Frank Williams, a man known for trusting instinct, and this is where the story takes its turn.
On Sunday, before the final announcement, the seat was, by most accounts, leaning toward Junqueira; safer choice and logical one.
Then something shifted…. by Monday morning, Frank Williams had changed his mind.
It came down to what he later described, in essence, as a feeling about potential; not just speed in that moment, but what a driver could become…
Jenson Button, despite his lack of experience, showed something harder to define, he adapted quickly; found pace almost immediately.
There was also a composure about him… no panic, no overdriving, and just quiet confidence, for a 20 years old stepping into a F1 car under that kind of scrunity; it stood out!
That was enough, five days after Jenson Button birthday, on January 24, 2000; Williams made it official, Button had the seat!
A Temporary Opportunity
What made the whole situation even more unusual was the context behind the decision; this one was never meant to be a long term commitment for Williams F1 Team.
They already had eyes on Juan Pablo Montoya for 2001, who was already a rising star at the CART racing series in the United States; and the plan was cleaer, if Montoya became available; he would step into that Williams seat.
Which meant Button, even before his first race, was effectively a short-term solution; a stop-gap, placed in one of the most competitive cars on the grid with limited time to prove himself.
At the same time, BMW had its own preferences; names like Jorg Muller were being considered early on.
But once the Barcelona test played out; Button’s pace made those discussions less relevant.

The Fine Margins That Changed Everything
Looking back, what stands out is just how close it all was. If the decision had been finalized even a day earlier, Button might never have raced for Williams, and his path into F1 could have been far more difficult.
Junqueira had the experience, the technical backing, and strong internal support; but on the other hand, Button showed adaptability, greater consistency, and that is why Frank believed he was the better option.
In the end, F1 chose potential over certainty, and that single decision, made almost at the last possible moment, quietly shaped the career of a future world champion, who in 2009; dominated F1 driving for Brawn GP, and then joined McLaren, one of the best teams in F1 history.
The What-If Story: Button vs Junqueira
That single test for the seat changed everything; it opened the door to F1 for Jenson Button.
For Bruno Junqueira; it quietly closed it… and he remains one of those drivers who nearly reached F1 debut, but never did, and he stayed on as a test driver with Williams through 2000 and 2001… but the race seaet never came; not there, and not anywhere else in F1.
Bruno moved on to race in the American series; F1 dream had already slipped away, it is one of those moments in motorsport history where timing matter just as much as talent.
There is always that lingering question. If Junqueira had been given the seat at Williams-BMW, could things have played out differently? He had the experience, the technical understanding, and the kind of discipline that teams rely on when fighting at the front. In the early 2000s, with a competitive car underneath him, he might well have been in the mix for wins. But F1 does not always reward the most prepared driver, sometimes it simply comes down to being chosen at the right moment.
For Junqueira, though, the story feels unfinished, and he had done enough to deserve a shot; at least a season to prove himself at that level, but that chance never came, and in F1, sometimes one missed opportunity is all it takes for a door to close for good.
