Williams have replaced Logan Sargeant with Franco Colapinto for the last nine races of the 2024 Formula 1 season.

Sargeant was already set to leave Williams at the end of the season, with Ferrari's Carlos Sainz set to take his seat for 2025.

However, his second season in F1 has been cut short, following a huge crash in the final practice session at the Dutch Grand Prix on Saturday.

In 36 races, Sargeant earned one point for Williams, compared to team-mate Alex Albon, who scored 31 points during that period.

Colapinto will make his competitive debut at the Italian Grand Prix this weekend, having previously driven for Williams in practice at the British GP earlier this year.

"It is an honour to be making my Formula 1 debut with Williams – this is what dreams are made of," Colapinto said.

"The team has such amazing history and a mission to get back to the front, which I can't wait to be part of.

"Coming into F1 mid-season will be an enormous learning curve, but I am up for the challenge, and I'm fully focused on working as hard as I can with Alex and the team to make it a success."

Williams team boss James Vowles admitted he was surprised that neither Red Bull nor Mercedes wanted to sign Carlos Sainz for the 2025 season.

The Spaniard signed a two-year contract with the option to extend at Williams earlier this week, ending speculation surrounding his future.

Ferrari had confirmed earlier this year that he would not continue with them past the end of the season, having signed Lewis Hamilton from Mercedes to partner Charles Leclerc.

While Sainz was initially seen as a candidate to replace Hamilton, Mercedes look set to promote 17-year-old Andrea Kimi Antonelli instead, while Red Bull preferred to extend Sergio Perez's contract for the next two years.

Vowles was full of praise for the 29-year-old, explaining how it was an easy choice to bring him into the team.

"Look at Carlos," said Vowles. "Look at every team he has been in. They have improved significantly - and I get why.

"After spending the last nine months talking to him at least weekly, what I've realised is he is a performance machine.

"He will do everything in his power to transform himself and the team around him. And that's powerful. That's worth more than what he can drive the car at.

[He is] one of the top four drivers - if not at times the number two driver on the grid. Why wouldn't you want that in your stable?"

Sainz has achieved three Formula 1 wins to date, including a victory at the Australian Grand Prix in March, and currently sits fifth in the drivers' championship.

He is only 15 points behind team-mate Leclerc, who sits in third, while his five podium finishes this season have also helped Ferrari to third in the constructors' championship, where they sit 63 points behind leaders Red Bull.

There is speculation that Mercedes could make a swoop for Max Verstappen for the 2026 season, despite his Red Bull contract running until 2028.

With so many F1 futures up in the air, Vowles was surprised to find out there was not more interest in their new driver.

"Red Bull have a constructors' championship at risk - I would have Carlos alongside Max [rather than Perez]," he added.

"Mercedes have more info than I do. It's more than likely that they are very confident in the direction they will be travelling in. Whether that will be Max or Kimi, I'm unsure - but they're not fools.

"Red Bull will also have reasons behind it that I won't be aware of because they are multiple world champions. They don't make decisions lightly, but I was surprised."

British racing driver Susie Wolff announced on this day in 2015 she would retire from motor sport at the end of the season.

Wolff, aged 32 at the time, had become the first female to take part in a Formula One race weekend in more than two decades in first practice at the 2014 British Grand Prix with Williams.

The Scot had also taken part in practice for the German Grand Prix that year as well as sessions in Spain in 2015 and again at Silverstone – but expressed her belief as she announced her retirement that F1 having a competitive female driver was something that was not going to happen soon.

Wolff – married to Mercedes boss Toto Wolff, who was a minority shareholder in the Williams team – said: “My progression into Formula One came to represent so much more than a racing driver simply trying to reach the pinnacle of the sport.

“It was also the hope that finally there may again be a female on the starting grid.

“I rode the wave, was energised by all the support and fought hard. There were those who wanted it to happen. Those who didn’t.

“I can only tell you, I gave it my all. Do I think F1 is ready for a competitive female racing driver that can perform at the highest level? Yes. Do I think it is achievable as a woman? Most definitely. Do I think it will happen soon? Sadly no.

“We have two issues – not enough young girls starting in karting at a young age and no clear role model. Sometimes you just have to see it to believe it. My gut feeling tells me it is time to move on.”

Wolff, who competed in Formula Renault, Formula Three and the German DTM series before her stint in F1, was appointed as Williams development driver in 2012 before being promoted to the role of test driver.

But her hopes of becoming the first woman to start an F1 race since Lella Lombardi in 1976 suffered a huge setback when Adrian Sutil was signed up by Williams after Valtteri Bottas sustained an injury in qualifying for the 2015 Australian Grand Prix, a move that appeared to scupper any long-term hope she had of competing for the team in a race.

Wolff added: “At 13, the dream and the goal became Formula One. I got oh so close.

“I wanted and fought very hard to make it onto that starting grid but the events at the start of this year and the current environment in F1 the way it is, it isn’t going to happen.”

In March of this year, Wolff was appointed managing director of the all-female F1 Academy series.

The series aims to develop and prepare young female drivers to progress to higher levels of competition.
