Marlene Knaus is best known as the first wife of Niki Lauda, one of the greatest drivers in Formula One history. Yet her place in Lauda’s story goes far beyond a famous marriage. She was with him during some of the most intense years of his racing life, including his near fatal crash at the Nürburgring in 1976.

The couple married in 1976 and spent about 15 years together before their divorce in 1991. They had two sons, Lukas Lauda and Mathias Lauda. Both later stayed connected to motorsport in different ways. Mathias became a professional racing driver, while Lukas worked as his manager.

Unlike her former husband, Marlene did not build a public career after their marriage ended. She chose a quiet life and rarely gave interviews. Even so, Niki later spoke with warmth about her. He said that his first and second families remained close and often spent time together.

Marlene Knaus Quick Bio

Who Is Marlene Knaus?

Marlene Knaus became widely known during the 1970s because of her relationship with Formula One champion Niki Lauda. Major biographical records describe her as Chilean Austrian. Other profiles have also linked her to modeling and fashion before her marriage.

Her public image was very different from Lauda’s. He lived in a world of race cars, television cameras, sponsors, reporters, and constant travel. She appeared beside him at racing events but did not seek the same level of attention.

That difference remained clear for decades. Niki continued to appear in public as a driver, businessman, airline owner, and Formula One executive. Marlene gradually moved away from the spotlight.

Her private nature is one reason firm details about her early years remain limited. Many online biographies repeat claims about her childhood and exact birth details without strong documentation. The best supported part of her story begins in Europe during the 1970s.

Marlene Knaus Before Meeting Niki Lauda

Before becoming linked with Lauda, Marlene moved within European social and fashion circles. She has often been described as a former model. Italian newspaper Corriere della Sera also described her as an ex model and photographer.

She was once involved with famous German Austrian actor Curd Jürgens. Accounts of Jürgens’s personal life state that he began a relationship with the Chilean Austrian Marlene in 1975. The couple became engaged but never married.

That relationship ended after she met Niki. Lauda was also in a long relationship at the time. He had been dating Mariella Reininghaus, who had accompanied him during the early part of his motor racing career.

The Guardian reported that Lauda left Reininghaus for Marlene in 1975. The two then married within months. Their relationship quickly became part of the public story surrounding one of Formula One’s fastest rising stars.

How Did Marlene Knaus and Niki Lauda Meet?

The exact details of their first meeting have been retold in several forms. What is well established is that they became a couple during 1975. At the time, Lauda was already becoming a major name with Ferrari.

His career had changed quickly. He joined Ferrari for the 1974 season and won his first Formula One World Drivers’ Championship in 1975. His success made him one of the most watched athletes in Europe.

Marlene entered his life during that period. Their relationship attracted attention because both had left previous partners. Yet the couple did not turn their wedding into a large public event.

Lauda later said that he managed to keep his first marriage secret for about six months even though he was already a Formula One world champion.

Marriage to Formula One Champion Niki Lauda

Marlene Knaus and Niki Lauda married in 1976. The marriage began at a remarkable time in his career. He had just won his first world title and started the 1976 season as the defending champion.

Lauda later said something interesting about their decision to marry. According to an interview, Marlene had not been eager to marry. Niki said he wanted marriage partly because most people he knew at his age were already married.

Their life together was never likely to be ordinary. Formula One in the 1970s was dangerous. Drivers faced a far greater risk of serious injury or death than modern racers do.

Marlene often appeared around the racing world with her husband. Archival photographs show her in paddocks and at Grand Prix events. Her presence made her a familiar face to fans, even though she was not part of the sport professionally.

Niki Lauda’s 1976 Nürburgring Crash

The most difficult event of their early marriage came on August 1, 1976, during the German Grand Prix at the Nürburgring. Lauda lost control of his Ferrari, hit a barrier, and his car caught fire.

Other drivers stopped and helped pull him from the burning vehicle. He suffered severe burns and serious damage from inhaling toxic fumes. His condition became so grave that he was given the last rites in hospital.

His recovery became one of the most famous stories in sporting history. Just six weeks after the crash, Lauda returned to Formula One. He raced again while his injuries were still healing.

For Marlene, the crash changed the first year of her marriage into a period of fear and recovery. She remained part of Lauda’s life as he rebuilt his health and resumed his career.

Niki narrowly lost the 1976 championship to James Hunt, but he returned to win another world title in 1977. Years later, he won his third championship with McLaren in 1984.

Marlene Knaus and Niki Lauda’s Children

The marriage produced two sons. Their older son, Lukas Lauda, was born in 1979. Their younger son, Mathias Lauda, was born on January 30, 1981, in Salzburg, Austria.

Mathias followed his father’s path into professional motorsport. He competed in several racing series, including the Deutsche Tourenwagen Masters, GP2, Porsche Supercup, NASCAR Whelen Euro Series, and endurance racing.

One of Mathias’s strongest results came in 2017. He won the FIA World Endurance Championship in the LMGTE Am class while racing with Aston Martin Racing.

Lukas chose a different role. Instead of becoming a racing driver, he worked on the management side and became Mathias’s manager. This meant both sons remained connected to the motorsport world that had shaped much of their childhood.

Why Did Marlene Knaus and Niki Lauda Divorce?

The couple divorced in 1991, after about 15 years of marriage. This date appears in several major biographical accounts of Lauda.

Niki later discussed the separation in unusually simple terms. He recalled that he was the one who wanted a divorce. According to him, Marlene accepted the decision as long as he remained himself and continued to look after her.

Their family history also included difficult personal issues. Lauda had another son, Christoph, from a relationship outside his marriage. Christoph was born during the period when Niki was still married to Marlene.

It would be misleading to claim that one event alone caused their divorce. Neither Marlene nor Niki presented the end of their marriage as a simple public scandal. What is clear is that they eventually ended the marriage while keeping an important personal connection.

Their Friendship After Divorce

One of the most unusual parts of the story came after the marriage ended. Marlene Knaus and Lauda remained close instead of becoming distant former spouses.

In an interview years later, Niki said that Marlene was still very much part of his life. He explained that she lived in Ibiza and that members of his old and new families regularly met.

The relationship also included Birgit Wetzinger, whom Lauda married in 2008. Niki said Birgit and Marlene became friends. He recalled going to restaurants with both women, his sons Lukas and Mathias, and other family members.

Lauda described his former wife as a secure, direct, warm hearted person. He also gave her much of the credit for making the unusual family arrangement work.

Their continued friendship shows that divorce did not erase their shared family bond. They had raised two children together and remained linked for the rest of Niki’s life.

Life Away From Formula One Fame

After her divorce, Marlene became much less visible in public. She did not try to build a media career from her former marriage. There were no regular television appearances, major interviews, or public efforts to turn her connection with Lauda into a business brand.

Niki’s own comments placed her in Ibiza, where their wider family also spent time. His description suggested that she remained part of family gatherings long after their legal marriage had ended.

This quiet lifestyle makes her different from many people linked with major sports stars. Her public recognition came through one of Formula One’s greatest drivers, but she did not appear interested in maintaining celebrity status.

Most later interest in her has come from fans who want to understand Lauda’s private life. The success of the movie Rush also brought a new generation of viewers to the story.

Marlene Knaus in the Movie Rush

The 2013 film Rush dramatized the famous 1976 Formula One rivalry between Niki Lauda and British driver James Hunt.

German Spanish actor Daniel Brühl played Lauda, while Chris Hemsworth appeared as Hunt. Alexandra Maria Lara played Marlene Lauda.

The film was directed by Ron Howard and written by Peter Morgan. It focused mainly on the rivalry between the two drivers, but their personal relationships were also important parts of the story.

Because Rush is a drama rather than a documentary, viewers should not treat every conversation or private scene as a literal historical record. Still, the movie made Marlene a recognizable figure to people who had never followed Formula One during the 1970s.

Relationship With the Wider Lauda Family

Niki Lauda later married Birgit Wetzinger, a former flight attendant connected to his airline business. They married in 2008 and welcomed twins Max and Mia in 2009.

This created a much larger Lauda family. Yet the first and second families were not kept completely separate.

Niki spoke openly about gatherings that included Marlene, Birgit, Lukas, Mathias, and other family members. His comments suggest that the adults found a way to maintain normal family ties without allowing the divorce to create a lasting split.

That relationship lasted through the later years of Lauda’s life. Niki remained close to his older sons while continuing to raise his younger twins with Birgit.

Niki Lauda’s Death

Niki Lauda died on May 20, 2019, at the age of 70. His death came after years of serious health problems that were partly linked to the injuries and medical treatment that followed his 1976 accident.

He had undergone kidney transplants and later received a lung transplant. His sporting career, survival, business success, and blunt personality had made him one of Formula One’s most respected figures.

For Marlene, his death meant losing someone who had remained part of her family for more than four decades. Their legal marriage had ended long before, but their friendship and family ties continued.

Their sons also remained an important part of Lauda’s legacy. Mathias carried the family name into professional racing, while Lukas built his own place behind the scenes.

Marlene Knaus Net Worth and Financial Life

There is no dependable public financial record that gives an exact personal net worth for Marlene. Online figures should therefore be treated with care.

Niki Lauda built significant wealth through both motorsport and aviation. After racing, he became closely involved in the airline business and created ventures such as Lauda Air. He also returned to Formula One in senior roles and later became non executive chairman of the Mercedes Formula One team.

Marlene’s financial affairs remained private. Niki did state publicly that after their divorce he continued to take care of her.

Without reliable financial documents, any precise multimillion dollar figure attached to her name would be speculation. Her biography is better understood through her family history than through unsupported wealth estimates.

Where Is Marlene Knaus Now?

Marlene Knaus has spent much of her later life outside the public spotlight. Niki Lauda said in an interview that she lived in Ibiza and remained closely connected with his family.

She has not maintained the public profile usually linked with former spouses of major sports stars. This makes current details about her daily life limited.

Her decision to stay private also explains why so many online reports about her contain conflicting details. Reliable sources give much more information about her marriage, children, and connection with Lauda than about her present routine.

What remains clear is her lasting place in the Lauda family story. She was beside Niki during his most dangerous racing years, became the mother of his two oldest sons, and remained his friend long after their divorce.

Final Thoughts

Marlene Knaus is often introduced simply as Niki Lauda’s ex wife, but that description leaves out much of her story. She entered his life just as he reached the top of Formula One and was there during the 1976 crash that nearly killed him.

Their marriage lasted from 1976 until 1991 and produced two sons, Lukas and Mathias. Even after the divorce, they maintained an unusually close friendship. Niki later spoke about her with respect and described her as an important part of his wider family.

She never followed Lauda into a highly public life. Instead, she protected her privacy and stayed largely outside the media. That choice has kept parts of her story out of public view, but it has also become one of the defining features of her life after Formula One fame.
