Marlene Knaus is best known as the former wife of Austrian Formula One champion Niki Lauda. A model before and during their relationship, she married Lauda in 1976 and shared some of the most consequential years of his racing career. Their marriage lasted until 1991, and they had two sons, Lukas and Mathias.
Public interest in Knaus increased after Lauda’s near-fatal crash at the Nürburgring in 1976 and returned decades later with the release of Rush, the 2013 film about Lauda’s rivalry with British driver James Hunt. Actress Alexandra Maria Lara portrayed Knaus in the film.
Despite her connection to one of motorsport’s most recognizable figures, Knaus has maintained a largely private life. Reliable information about her family, marriage, and modeling background is available, but many online claims about her age, finances, and current residence lack consistent verification.

Early Life and Background
Marlene Knaus’s early life has not been comprehensively documented in widely available biographical sources. However, an interview published by the Chilean newspaper El Mercurio in 2024 provided an important detail about her family background. Her son Lukas Lauda said that his mother and her three siblings grew up and attended school in Valdivia, Chile.
That account offers a more reliable starting point than the conflicting birthplace and nationality claims found on many celebrity biography websites. Her exact birth date and year remain uncertain in the available public record, so assigning her a specific age would risk presenting an unverified detail as fact.
Before her marriage to Lauda, Knaus was described in contemporary reporting as a model or photomodel. An archived photograph from December 1974 also identified her as the companion of actor Curd Jürgens. This provides evidence of her public life before her relationship with the racing driver became widely known.
Beyond these details, information about her parents, education, and childhood experiences remains limited. A careful biography should acknowledge those gaps rather than fill them with speculation.
Marlene Knaus’s Modeling Career
Knaus was described as a model in contemporary coverage of her relationship with Niki Lauda. A report from the period surrounding their 1976 wedding referred to her as a photomodel, supporting the basic description of her profession.
Her appearance and personal style also attracted attention during the 1970s, when she was photographed at social events and Formula One races alongside Lauda. Archival photographs document her presence at the Belgian Grand Prix in May 1976 and at other public occasions during their marriage.
However, detailed records of her modeling agencies, fashion campaigns, magazine covers, and professional achievements are limited. Claims that she established a major fashion-design or photography career are not sufficiently supported by reliable documentation.
The most defensible description is that Knaus worked as a model before becoming widely recognized through her marriage to Lauda. Her later public identity was closely associated with the Formula One world, although she was not a racing driver or a professional motorsport figure in her own right.
Marriage to Niki Lauda
Marlene Knaus married Niki Lauda on March 11, 1976, in a private civil ceremony. At the time, Lauda was already an established Formula One driver, competing at the highest level of international motorsport.
Lauda had won his first Formula One World Drivers’ Championship with Ferrari in 1975. His marriage to Knaus began just before the dramatic 1976 season, which would become one of the defining chapters of his career.
Knaus accompanied Lauda during parts of his racing life and became a familiar face around the Formula One paddock. Photographs from the period document their appearances together, providing a glimpse of their relationship during his rise to international prominence.
Their marriage was not simply a story of celebrity and sporting success. It also unfolded during periods of considerable uncertainty, particularly after Lauda suffered a devastating accident at the German Grand Prix in August 1976.
Marlene Knaus and Niki Lauda’s 1976 Crash
On August 1, 1976, Lauda suffered a near-fatal crash at the Nürburgring during the German Grand Prix. His Ferrari caught fire after leaving the track, and he sustained severe burns and serious lung injuries.
Several drivers stopped to help pull him from the burning car. Lauda survived despite the severity of his injuries and returned to Formula One competition just six weeks later at the Italian Grand Prix.
The accident became one of the most widely remembered events in Formula One history. It also had consequences for Lauda’s family, including Knaus, who experienced the uncertainty surrounding his survival and recovery.
In later interviews, their son Mathias recalled that his mother strongly opposed the idea of her children pursuing racing after witnessing what happened to his father. Despite those concerns, Mathias eventually became a racing driver himself.
These family recollections offer a more personal perspective on the accident than the sporting statistics alone. They show how a moment remembered for Lauda’s determination also affected the people closest to him.
Marlene Knaus’s Children
Marlene Knaus and Niki Lauda had two sons, Lukas and Mathias. Both became part of Lauda’s family legacy, although their professional paths differed.
Lukas Lauda
Lukas Lauda is the elder son of Marlene Knaus and Niki Lauda. He has been associated with his younger brother Mathias’s professional activities, including his racing career.
Lukas has occasionally discussed family history in interviews, offering insights into his mother’s childhood in Chile and the family’s experiences during Lauda’s racing years. His comments are particularly useful because much of Knaus’s personal background has otherwise remained private.
Mathias Lauda
Mathias Lauda was born on January 30, 1981, in Salzburg, Austria. He followed his father into motorsport and developed a professional career as a racing driver.
Mathias competed in several racing categories, including Formula 3000, the GP2 Series, and sports car racing. In 2017, he won the FIA World Endurance Championship title in the LMGTE Am category with Aston Martin Racing.
His career illustrates the continuation of the Lauda family’s connection to motorsport, even though his mother reportedly had reservations about racing after his father’s accident.
Why Did Marlene Knaus and Niki Lauda Divorce?
Marlene Knaus and Niki Lauda divorced in 1991 after approximately 15 years of marriage.
The specific private circumstances that led to their separation have not been established in sufficient detail through reliable public reporting. It is therefore more accurate to record the marriage and divorce dates than to attribute the breakup to unverified allegations or speculation.
Following their separation, Knaus maintained a comparatively private life. Lauda later married Birgit Wetzinger in 2008, and they had twins, Max and Mia, in 2009.
Lauda remained a prominent figure in Formula One as a three-time world champion and later served in a leadership role with the Mercedes Formula One team. Knaus, by contrast, did not pursue a similarly visible public career.
Marlene Knaus in Rush
Interest in Marlene Knaus reached a new audience with the release of Rush in 2013. Directed by Ron Howard, the film dramatizes the rivalry between Niki Lauda and James Hunt during the 1976 Formula One season.
German actress Alexandra Maria Lara portrayed Knaus in the movie. The film depicts aspects of Lauda’s personal life alongside his competition on the track, including the relationship with his wife during the period surrounding his crash.
However, Rush is a dramatic feature film, not a documentary or a complete account of Knaus’s life. Its portrayal of her should be understood as a cinematic interpretation rather than definitive evidence of her private thoughts or experiences.
For many viewers, the film introduced Knaus to a new generation of motorsport fans. It also renewed interest in the people who shared Lauda’s life away from the circuit.
Marlene Knaus’s Life After Divorce
After her divorce from Lauda, Knaus largely withdrew from public attention. Unlike her former husband, who continued to appear regularly in Formula One coverage, she did not maintain a prominent media presence.
Historical accounts connect the family with Spain and Ibiza, but these references do not establish where Knaus currently lives. Reliable public information about her present activities, relationships, and daily life is limited.
Her sons have occasionally provided glimpses into their family background, but Knaus herself has not maintained a widely documented public profile through regular interviews or public appearances.
This relative privacy is an important part of her story. Although her name remains associated with a major figure in motorsport, her life should not be reduced to assumptions about what she does today.
Marlene Knaus’s Net Worth
Marlene Knaus’s personal net worth has not been established by a reliable public estimate.
Although she was married to a successful Formula One driver and businessman, Niki Lauda’s wealth cannot be used as a substitute for information about her individual finances. Publicly available sources do not provide enough verified information about her assets, income, investments, or financial arrangements to support a specific figure.
For that reason, estimates circulating on celebrity websites should not be treated as established facts.
