Marlene Knaus is a former model best known as the first wife of Formula One legend Niki Lauda. The couple married in 1976, divorced in 1991, and had two sons, Lukas Lauda and Mathias Lauda. Although her name became closely linked with one of motorsport’s most famous figures, Knaus has maintained a far lower public profile than her former husband.
Her story is most closely tied to the years when Lauda became one of Formula One’s defining champions, including the dramatic 1976 season when he survived a near-fatal crash at the Nürburgring. Beyond that connection, much of Knaus’s own biography remains less documented, with many online claims about her personal life, finances, and later years lacking reliable confirmation.

Early life and background
Details about Knaus’s early years have often been repeated online with conflicting information. Stronger family-linked evidence points to Valdivia, Chile, as an important part of her background.
In a 2024 interview with Chilean newspaper El Mercurio, her son Lukas Lauda said that his mother and her three siblings grew up and attended school in Valdivia. The interview also connected her family history to the 1960 Valdivia earthquake, one of the most powerful earthquakes ever recorded.
Some sources have offered different birth details and national descriptions. A 1956 birth year has been reported through family-linked accounts, but earlier contemporary reports from the 1970s gave conflicting ages. Because those records do not align, Knaus’s exact birth date has not been conclusively established.
Career before public attention
Knaus was already known publicly before her marriage to Lauda. Contemporary reporting from the 1970s described her as a photomodel, which is the strongest documented description of her professional work.
Some modern biographies have expanded this into broader claims about fashion, design, or other careers, but reliable evidence for those descriptions has not been established. The confirmed record supports identifying her as a model rather than attributing a larger professional portfolio.
Before her relationship with Lauda, Knaus was also publicly associated with Austrian actor Curd Jürgens. Archival photographs and later reporting document that connection during the mid-1970s, before her marriage to Lauda.
Marriage to Niki Lauda
Knaus and Lauda married in 1976 during a defining period of the racing driver’s career. Contemporary reports placed their wedding on March 11, 1976, in a private civil ceremony.
The marriage coincided with one of the most dramatic chapters in Formula One history. On August 1, 1976, Lauda suffered severe injuries in a crash at Germany’s Nürburgring circuit. He returned to racing only weeks later, becoming known for both his resilience and his continued involvement in motorsport.
Family accounts suggest that the accident had a lasting impact on how racing was viewed inside the household. In a 2024 interview, Lukas Lauda recalled that motorsport was effectively discouraged at home because of what his mother had witnessed during Lauda’s crash.
Family life and children
Marlene Knaus and Niki Lauda had two sons:
- Lukas Lauda, born in 1979.
- Mathias Lauda, born in 1981.
Both sons later developed connections to motorsport. Mathias became a racing driver, while Lukas worked closely with him as a manager.
Niki Lauda later spoke publicly about the division of responsibilities during their marriage. In a 2012 interview cited in later profiles, he acknowledged that Knaus carried much of the responsibility for raising their first two children while his own career demanded significant attention.
After the divorce, family accounts indicate that Lukas and Mathias remained in Spain with their mother while Lauda continued his own life separately.
Life in Spain and Ibiza
Ibiza became an important location in the Lauda family story during their marriage. Reports from the 1980s described Lauda acquiring a property on the island and connecting the move with creating a quieter environment for family life.
Later interviews with Lauda also discussed the family’s move toward Spain. These accounts establish Ibiza and Spain as significant parts of the family’s history, but they do not confirm that Knaus currently lives there.
Divorce and relationship with Niki Lauda
Knaus and Lauda divorced in 1991. The date is well documented, but the exact reasons behind the separation are not reliably established.
Many online profiles present specific explanations for the divorce, including claims about personal conflicts or outside relationships. However, the available reliable record confirms the divorce itself rather than one definitive cause.
After the separation, Knaus largely remained outside the public spotlight. Her connection to Lauda continued through their children and through the wider public interest in Lauda’s life and career.
Marlene Knaus and Rush
A new generation became familiar with Knaus through Rush, Ron Howard’s 2013 film about the rivalry between Niki Lauda and James Hunt.
In the film, Marlene Lauda was portrayed by actress Alexandra Maria Lara. The character was based on Knaus, but the movie is a dramatized interpretation of historical events rather than a documentary record of her private life.
For audiences who know Knaus mainly through Rush, the real historical record is more limited: she was a model, Lauda’s first wife, the mother of his two sons, and a person connected to one of Formula One’s most memorable eras.
What is known about Marlene Knaus today?
Knaus has remained a private figure in comparison with Niki Lauda and their sons. Publicly available information about her current life is limited.
Family-related comments in recent years confirm that she has remained part of her sons’ lives, but there is no reliable public confirmation of her current residence, whether she remarried, or her personal financial situation.
Claims about Marlene Knaus’s net worth are not supported by publicly documented financial records. A marriage to a wealthy and successful sports figure does not by itself establish an individual’s assets or financial position.

Conclusion
Marlene Knaus remains best known as the woman who shared an important chapter of Niki Lauda’s life, but her own public story is more restrained. The strongest evidence describes a Chile-connected former model who married Lauda in 1976, raised their two sons, and experienced the pressures surrounding one of Formula One’s most intense periods.
Her biography also illustrates the difference between public interest and documented history. While many details about her have circulated online, the clearest record is built around her family, her marriage to Lauda, and the lasting connection she has through their children and the legacy of a Formula One champion.
