Toto Wolff: Mercedes has unfinished business after Kimi Antonelli’s historic F1 title

Toto Wolff has made it clear that Kimi Antonelli's historic Formula 1 World Championship is only half the job.

Mercedes can clinch the 2026 Constructors' Championship at this weekend's São Paulo Grand Prix.

They need to outscore Ferrari by just three points.

Wolff spoke after Antonelli secured his maiden title in Mexico City.

The team principal acknowledged the contrasting emotions inside the team.

Antonelli celebrated his remarkable achievement.

George Russell was left reflecting on a championship challenge that fell short.

"Mexico was a special weekend for Kimi and the team," Wolff said.

"Winning the World Championship is an incredible achievement, particularly at this stage of his career, and he thoroughly deserves the moment."

Wolff then turned to Russell.

"For George, there is natural disappointment."

"He has been hard on himself but he has driven at an incredibly high level this season and shown again the quality we know he has."

Wolff pointed to factors outside Russell's control.

"There have been circumstances out of his control that haven't always fallen his way, and we have not always given him the car to perform."

"Nevertheless, the way he has continued to push and contributed to the team says so much about him."

Russell began the season as Mercedes' established leader.

He won the opening race in Australia.

But Antonelli's remarkable progression transformed the championship battle.

The 20-year-old Italian emerged as the team's first World Champion of the new regulations era.

Wolff's immediate priority is the Constructors' title.

"Our focus, though, has already moved to São Paulo," he said.

"We came into this season wanting to fight for both championships and there is still a job left to finish."

He stressed what the teams' title means.

"The teams' title is about the performance of the entire operation, both at the track and back in Brackley and Brixworth, and securing it would mean a great deal to all of us."

Wolff warned against complacency.

"Nothing is won yet, though."

"Interlagos is always a demanding weekend and there is little margin for error."

"We need to execute strongly from the first session and put ourselves in the best possible position."

Mercedes' Brackley chassis operation and Brixworth power unit division have combined to put the team in this position.

The Constructors' Championship would reward the entire organization.

Ferrari is the only team that can still catch Mercedes.

The gap is just three points.

Interlagos is a historic circuit known for unpredictable weather and tight racing.

Wolff also addressed the broader narrative around Antonelli's title.

He called the young driver a role model.

"We have a new champion that represents values – humility, integrity, loyalty, respect, being himself," Wolff told Sky Sports in Mexico.

"He should be a role model for many other young drivers in junior formulas."

Wolff took a subtle jab at other drivers.

"He should be a role model for the few entitled ones in Formula 1 – the endless moaners on the radio, the ones that complain, the ones that crash."

He said Antonelli represents "modern Formula 1."

"The talent is there with everyone."

"But you have got to be a good person."

Max Verstappen fired back at Wolff's comments.

"If we all had the same personality, things would be boring," Verstappen said in the drivers' press conference ahead of the Brazilian GP.

Fernando Alonso agreed, saying he had "nothing to add" to Verstappen's remarks.

The clash highlights the different philosophies in the paddock.

Wolff's investment in Antonelli dates back years.

The team principal decided early to back the young Italian.

That decision paid off in Mexico.

Now Mercedes needs one more result to complete the double.

The São Paulo Grand Prix takes place this weekend.

Mercedes leads Ferrari by three points.

If they outscore Ferrari by any margin, the Constructors' title is theirs.

If Ferrari out-scores them, the fight continues to the final race.

Wolff made it clear the team is not celebrating yet.

The focus is entirely on execution in Brazil.

Russell will be motivated to contribute after his title disappointment.

Antonelli will aim to cap his championship season with a team trophy.

The Brackley and Brixworth teams have worked all year for this moment.

Wolff wants to reward them.

"Securing it would mean a great deal to all of us," he said.
