Torger Christian "Toto" Wolff (German pronunciation: [volf], born 12 January 1972) is an Austrian billionaire investor, motorsport executive and former racing driver.

He specialises in strategic investments in medium-sized industrial and listed companies, which have included Williams F1 and German HWA AG.

[6] Investments included the German HWA AG, in which Wolff bought a 49% stake in 2006,[7] listing the company on the stock exchange in 2007.

[9] In April 2020, Wolff acquired a 4.95% stake in Aston Martin Lagonda Global Holdings plc as a financial investment, which subsequently was diluted to less than 1%.

In August 2021, Wolff was present in Berlin as Mercedes won both the drivers' and teams' championships in Formula E,[16] at a race won by Venturi driver Norman Nato,[16] where his wife, Susie Wolff, became the first female team principal to stand on the podium at a world championship motor race.

[21] Wolff has also served as an instructor at the Walter Lechner Racing School and in 2009 became a lap-record holder on the Nürburgring Nordschleife in a Porsche RSR.

[6] In 2012, he was named executive director of Williams F1[7] and the team took its last race win to date at that year's Spanish Grand Prix with Pastor Maldonado.

In addition to joining the team as managing partner,[24] he also acquired 30% of Mercedes-Benz Grand Prix Ltd, with a further 10% held by Niki Lauda and 60% by the parent company.

As co-owner of both Williams F1 (where his wife Susie worked as a test driver until November 2015) and Mercedes Grand Prix, Wolff celebrated numerous podiums and successes for both teams, such as a 1–2–3–4 finish at the 2014 Austrian Grand Prix in Spielberg, Austria in his 'home race', as well as at Monza, Italy, in both Qualifying and Race classifications.

[26] Wolff subsequently received the President's Award from Todt, along with team non-executive chairman Niki Lauda, at the 2018 FIA Prize Giving Gala held in St Petersburg, Russia.

The team followed up the achievement with an eighth consecutive constructors' world championship in 2021, but narrowly missed out on the drivers' crown after a controversial Abu Dhabi Grand Prix, in which Max Verstappen edged out Hamilton for the title.

After the 2020 F1 season, Wolff signed a new deal with Mercedes to continue as team principal and CEO for at least another three years, increasing his ownership stake to 33% upon investment from Ineos, becoming equal shareholders with Daimler AG.

[37] In November 2021, Wolff was appointed to an Associate Fellowship of the Oxford Saïd Business School for two years to transfer his understanding of high-performance culture, team leadership, and personal effectiveness from the racetracks into the classroom.

[38] In February 2022, Wolff's leadership of the Mercedes-AMG Petronas F1 Team was the subject of a Harvard Business School case study,[39] authored by Anita Elberse.

Wolff visited Harvard on 3 March 2022 to teach the case study to MBA students and lead a discussion on high-performance leadership and organisational culture.

[40] In May 2022, Wolff was named as an executive fellow at Harvard Business School, a role in which he will serve as guest lecturer alongside Professor Anita Elberse.
