Kimi Antonelli’s historic Formula 1 championship triumph in Mexico City nearly ended in heartbreak after Mercedes discovered a serious mechanical problem that could have forced the Italian to retire just moments before securing one of the most important podium finishes of his career. While the 20-year-old celebrated becoming the youngest world champion in Formula 1 history, revelations from inside Mercedes have exposed just how close his championship-winning weekend came to an unexpected disaster.
Antonelli finished third at the Mexican Grand Prix behind Max Verstappen and Lewis Hamilton, collecting the points needed to mathematically secure the 2026 Drivers’ Championship. However, Mercedes deputy team principal Bradley Lord has revealed that the Italian was battling an oil leak during the closing stages of the race, with the severity of the problem only becoming apparent after the team examined his car.
The discovery has transformed the story surrounding Antonelli’s championship celebration, raising questions about how Mercedes managed to bring its young star home despite a potentially race-ending mechanical failure.
MERCEDES DISCOVERS SERIOUS OIL LEAK AFTER ANTONELLI’S MEXICO GP PODIUM
Antonelli’s third-place finish initially appeared to be a controlled performance from a driver who understood that the championship was within reach.
With Verstappen and Hamilton fighting for victory ahead, the Mercedes driver maintained his position without taking unnecessary risks. His primary objective was to finish the race and secure the points required to become world champion.
However, the reality inside Mercedes was considerably more concerning.
Speaking on the High Performance Racing Podcast, deputy team principal Bradley Lord revealed that the team discovered extensive oil contamination after removing the floor from Antonelli’s car following the Grand Prix.
Lord explained that something had cracked, allowing oil to spread across the underside of the vehicle.
The discovery immediately raised concerns about how close Antonelli had come to losing the opportunity to celebrate his championship in Mexico.
According to Lord, the driver himself believed that his engine had begun struggling approximately four laps before the finish.
That revelation suggests Antonelli was not simply managing his pace during the closing stages but potentially fighting to keep his championship-winning car running until the chequered flag.
KIMI ANTONELLI WAS ‘RIGHT ON THE EDGE’ OF RETIREMENT
The most alarming part of Mercedes’ revelation was Lord’s assessment of the situation.
“Right on the edge of retirement on that race, and yet it held together,” he explained.
The statement provides a dramatic insight into the risks Antonelli faced during the closing laps.
Had the mechanical problem developed further, Mercedes could have been forced to withdraw its driver from the race. That would have dramatically changed the championship celebrations and potentially delayed his coronation until another Grand Prix.
Antonelli’s third-place finish was enough to secure the title, meaning a retirement could have left him waiting for another opportunity to officially become champion.
Although the precise mechanical failure and its full implications were not detailed in the report, the discovery of an oil-covered floor and the driver’s reported engine struggles indicate that Mercedes had a serious issue to investigate.
For the team, the fact that the car survived was an enormous relief.
For Antonelli, it meant that a potentially devastating mechanical failure did not prevent him from achieving the biggest milestone of his racing career.
THE PODIUM THAT ALMOST NEVER HAPPENED
Antonelli’s Mexico GP podium has already become one of the most memorable images of the 2026 Formula 1 season.
Standing alongside Verstappen and Hamilton, the young Italian was surrounded by two drivers who have dominated different eras of the championship.
Verstappen represents the modern Red Bull generation that reshaped Formula 1’s competitive landscape, while Hamilton remains one of the sport’s most successful champions following his years of dominance with Mercedes.
The symbolic significance of Antonelli sharing the podium with both drivers was immediately apparent.
It represented the arrival of a new generation at the top of Formula 1, with the two established stars effectively sharing the spotlight with the sport’s latest champion.
However, Mercedes’ revelation has added another dimension to the photograph.
The podium was not simply the result of Antonelli’s impressive performance and championship-winning consistency. It was also the outcome of a race in which his car survived a potentially serious mechanical problem.
Had the oil leak forced him to retire, the historic image might never have happened.
That possibility makes the Mexican Grand Prix an even more remarkable chapter in Antonelli’s extraordinary season.
MERCEDES’ RELIABILITY QUESTIONS EMERGE AFTER HISTORIC TITLE WIN
Antonelli’s championship victory represents a major achievement for Mercedes, but the discovery of the oil leak creates an important technical question for the team.
A world championship cannot be secured through speed alone.
Reliability, engineering precision and the ability to deliver consistent performance across an entire season are equally important factors.
Mercedes has enjoyed a highly successful 2026 campaign, with Antonelli emerging as the dominant force in the championship. However, the Mexican GP incident demonstrates that even a winning car can experience serious mechanical difficulties at critical moments.
The team will now need to establish exactly what cracked, why the oil leak developed and whether the issue could affect other components or future races.
That investigation becomes particularly important as Mercedes continues its pursuit of the constructors’ championship.
Although Antonelli has already secured the drivers’ title, the remaining races still carry considerable importance for the team and its commercial, competitive and technical objectives.
A repeat of the Mexican reliability scare could compromise Mercedes’ ability to finish the season strongly.
GEORGE RUSSELL’S MEXICO DISAPPOINTMENT CONTRASTS WITH ANTONELLI’S TITLE SUCCESS
The contrast between Antonelli and George Russell at the Mexican Grand Prix was particularly striking.
While Antonelli celebrated a historic championship victory despite a mechanical scare, Russell endured another frustrating weekend that exposed the difficulties of his 2026 campaign.
Russell started second but immediately lost ground following a deployment problem on the opening straight.
His race subsequently deteriorated further after a collision with Isack Hadjar resulted in a 10-second penalty, leaving him to finish sixth.
The British driver has already admitted that 2026 has been one of the most difficult seasons of his career, describing a campaign characterised by poor performances, technical setbacks and frequent confusion.
Antonelli’s success has consequently intensified the pressure surrounding Russell, who entered the season hoping to challenge for the championship himself.
The Mexican GP demonstrated the contrasting fortunes of Mercedes’ two drivers.
One emerged as the youngest world champion in Formula 1 history, while the other left the weekend searching for answers after another disappointing result.
Yet Antonelli’s own mechanical problems provide an important reminder that his championship success was not achieved without challenges.
ANTONELLI REJECTS NUMBER ONE FOR 2027 DESPITE BECOMING WORLD CHAMPION
Following his championship victory, Antonelli has already made an important decision concerning his Formula 1 identity.
The Italian will retain his familiar number 12 for the 2027 season rather than switching to number one, which is traditionally available to the reigning world champion.
His decision places him alongside Lewis Hamilton, who famously continued using number 44 throughout his championship-winning years instead of adopting the champion’s number.
Antonelli explained that number 12 holds special significance for him and represents an opportunity to remain grounded following his extraordinary achievement.
The number also carries a connection to Ayrton Senna, whose use of 12 during his Lotus years and first championship-winning season at McLaren helped make it memorable among Formula 1 fans.
Antonelli additionally admitted that superstition played a role in his decision.
He explained that whenever he had used number one previously, things had gone badly, giving him another reason to avoid changing his familiar racing number.
The decision reinforces Antonelli’s desire to approach 2027 as a fresh challenge rather than allowing his championship success to define his next season.
WHY ANTONELLI’S MEXICO GP EXPERIENCE COULD SHAPE HIS 2027 TITLE DEFENCE
Antonelli’s championship victory has established him as one of Formula 1’s most important emerging talents.
However, the mechanical scare in Mexico provides an early reminder of the difficulties that accompany championship success.
As reigning world champion, Antonelli will enter 2027 with considerably greater expectations and scrutiny.
Rivals will be determined to challenge his position, while Mercedes will face pressure to provide a reliable car capable of defending the title.
The Italian will also need to demonstrate that his championship success was not simply the result of favourable circumstances or a superior package.
His ability to remain composed during difficult races, manage technical setbacks and consistently deliver results will become increasingly important.
The Mexican GP offered a glimpse of that resilience.
Despite reportedly experiencing engine struggles during the closing laps, Antonelli continued until the finish and secured the podium that confirmed his championship triumph.
That experience could prove valuable as he prepares for the demanding responsibility of defending his title.
KIMI ANTONELLI’S CHAMPIONSHIP CELEBRATION WAS CLOSER TO DISASTER THAN FANS REALISED
Mercedes’ revelation has transformed the narrative surrounding Antonelli’s historic Mexican Grand Prix.
What initially appeared to be a comfortable championship-clinching podium was actually a race in which the Italian reportedly came dangerously close to retirement.
The oil leak discovered after the finish, combined with Antonelli’s belief that his engine began struggling with four laps remaining, suggests Mercedes narrowly avoided a potentially devastating outcome.
For the team, the discovery offers both relief and a warning.
The championship has been secured, but reliability remains an essential priority as Mercedes prepares for the final races of 2026 and the challenges of defending its position next season.
Antonelli, meanwhile, can celebrate a title that nearly slipped away for reasons entirely beyond his control.
The youngest world champion in Formula 1 history has already demonstrated extraordinary speed, maturity and consistency throughout the campaign.
Now, the revelation from Mexico adds another remarkable detail to his championship story: Kimi Antonelli did not simply survive the pressure of becoming world champion. He may also have survived a mechanical failure that nearly prevented him from celebrating it at all.
