Who Is Marlene Knaus? Former Model and Niki Lauda’s Ex-Wife

Marlene Knaus is a former European fashion figure and the first wife of Niki Lauda, the Austrian racing driver who won three Formula 1 World Drivers’ Championship victories that cemented his place among motorsport’s most respected figures. She was there during the most dramatic period of his career, beside him through the 1976 Nürburgring crash that nearly killed himthrough his remarkable return to racing just six weeks after his accident and the unforgettable championship battle with James Hunt that became a defining chapter in Formula 1 history. She and Niki married in 1976, had two sons together, Lukas and Mathias, and divorced in 1991 after fifteen years of marriage. She has lived privately since then, most closely associated with Ibiza, Spain, where Niki himself confirmed she was based. The 2013 Ron Howard film Rush, which dramatised the 1976 rivalry between Lauda and James Hunt, brought her story to a new generation. Alexandra Maria Lara played her in the film. Here is everything that is actually verified about Marlene Knaus, with speculation clearly labelled as such.

Quick Facts: Marlene Knaus

Who Is Marlene Knaus?

Marlene Knaus was an Austrian fashion figure who became part of European social circles during the late 1960s and 1970s, later gaining wider public attention through her relationship with Formula 1 champion Niki Lauda. She was publicly linked with Austrian-German actor Curd Jürgens before she met Lauda and was his companion at various social events in the mid-1970s. She married Niki Lauda in 1976 and stood by him during a remarkable period in his racing career, including one of the most dramatic seasons in Formula 1 history. She is the mother of Lukas Lauda and Mathias Lauda, both of whom have maintained connections to motorsport in their adult careers. She has not remarried since the 1991 divorce and has given very few public interviews throughout her life.

Early Life and Family Background

Marlene Knaus was reportedly born in 1956. Her exact date of birth has not been publicly verified She is commonly described as Austrian, though labels including American-Austrian and Chilean-Austrian have also appeared in various biographical accounts. None of these nationality descriptions are definitively established by any primary public record. Claims connecting her birthplace to the United States or her ancestry to Venezuelan or German descent have also appeared in various online sources. None of these are supported by firm primary documentation.

What is established is her presence in European social and fashion circles from the late 1960s and through the 1970s and her connection to the Austrian and broader European world that Niki Lauda also inhabited. Her early life before she became publicly known remains one of the least documented aspects of her story. Any specific claim about her childhood, family background, or education should be treated as unverified unless a credible primary source can be identified to support it.

Her Career in Fashion: What Can Be Verified

Marlene Knaus is widely described as a former model and 1970s fashion figure. She is sometimes called an It Girl of that era. Photographs from the period show her at high-profile European social events with an appearance and style that clearly fit the visual culture of 1970s European fashion. The precise details of her modelling career, however, are less clearly documented. Publicly available sources do not consistently document agency affiliations, specific runway appearances, campaign contracts, magazine covers, or credited photography involving her.

Her documented visual record in archival photography supports her presence in fashionable and elite European social circles. It supports the general description of her as a fashion figure of that period. It does not definitively establish a detailed professional modelling résumé with named clients and specific credits. The honest summary is this: she was a genuine presence in the European fashion and social world of the 1970s. The precise professional contours of that career are less firmly established than the general description suggests.

Before Niki Lauda: The Curd Jürgens Connection

Before her relationship with Niki Lauda, Marlene Knaus was publicly linked with Curd Jürgens, the Austrian-German actor who had a significant film career across European and Hollywood productions in the 1950s, 1960s, and 1970s. Getty Images archives photographs dated December 17, 1974, showing Jürgens alongside Knaus at his chalet in Gruben, Switzerland. The caption on those archival images identifies her as his companion. This record provides one of the strongest documented details about Marlene’s life before her marriage to Lauda.

Those photographs place her firmly within European celebrity and social circles at the highest level well before she became associated with Formula 1 through her relationship with Lauda. She was not an unknown figure who suddenly appeared in a racing driver’s life. She was already moving in the elite social world of 1970s European entertainment. Curd Jürgens himself was a significant figure. He appeared in films including The Spy Who Loved Me in 1977 alongside Roger Moore as the Bond villain Karl Stromberg, which reflected his standing as one of the more recognisable European actors of that generation.

How Marlene Knaus Met Niki Lauda

Marlene and Niki met around 1975, most accounts placing the meeting in Salzburg. Their courtship was reportedly brief, sometimes described as approximately two months, before the relationship became serious. She was linked with Curd Jürgens at the time of their meeting. Niki Lauda had been in a long term relationship of approximately eight years before choosing to pursue Marlene. The transition from that previous relationship to his marriage to Marlene happened within a relatively short period.

Some accounts place their introduction at a dinner party in Salzburg, with Mariella von Reininghaus named in some versions of the story. The precise circumstances of the introduction are not definitively established in any primary source. What is clear is that by 1976 they were married and that Niki’s feelings about Marlene were serious enough for him to make a significant personal transition to be with her.

Who Was Niki Lauda?

To understand Marlene Knaus’s place in motorsport history it is necessary to understand who Niki Lauda was and what his career represented. Andreas Nikolaus Lauda was born on February 22, 1949 in Vienna, Austria into a wealthy family that wanted him to pursue business rather than racing. He borrowed money to start his racing career against his family’s wishes and worked his way up through Formula 3 and Formula 2 before reaching Formula 1. He joined Ferrari in 1974 and transformed the team through his technical intelligence and precise understanding of car setup. He won the Formula 1 World Drivers’ Championship in 1975 and was on course to defend it comfortably in 1976 before the accident at the Nürburgring changed everything.

After his return to racing and his points deficit from the accident he ultimately lost the 1976 championship to James Hunt by a single point. He then won his second championship with Ferrari in 1977. He retired from Formula 1 in 1979 to focus on Lauda Air, the airline he had founded. He returned to Formula 1 with McLaren in 1982, coming back from two and a half years away, and won his third world championship in 1984 by half a point over his teammate Alain Prost, the smallest championship winning margin in the history of the sport. After his second retirement from racing he became a significant figure in aviation and later in Formula 1 team management, serving as non-executive chairman of Mercedes where he played a central role in their dominant era with Lewis Hamilton. He died on May 20, 2019 at the age of 70 following complications from a lung transplant he had received the previous year.

The 1976 Nürburgring Crash: The Most Defining Moment

The German Grand Prix on August 1, 1976 at the Nürburgring is one of the most significant events in the history of motor racing. Marlene was Niki’s wife throughout what followed. On the second lap of the race Lauda lost control of his Ferrari on a section of track and the car caught fire after striking barriers. Fellow drivers Arturo Merzario, Harald Ertl, Brett Lunger, and Guy Edwards stopped and pulled Lauda from the burning car at enormous personal risk. He had been trapped for approximately a minute in the flames. The injuries were severe. He suffered burns to his face and head and critically, he inhaled toxic fumes from the burning car which caused serious lung damage. He was given the last rites at the hospital. His situation was described as life threatening.

What happened next became one of the most celebrated stories in sports history. Six weeks later, on September 12, 1976, Niki Lauda returned to racing at the Italian Grand Prix in Monza. He still had wounds on his head and face that had not fully healed. He wore a specially designed helmet and raced through genuine physical pain and discomfort. He finished fourth. He was still mathematically in the championship. The championship fight then came down to the Japanese Grand Prix at Fuji in October 1976. In torrential rain that made conditions extremely dangerous Lauda withdrew from the race after two laps, unable to see clearly because of the eye damage from the crash. James Hunt finished third, which was enough to win the championship by one point. Marlene was his wife throughout that entire arc. The crash, the hospital, the recovery, the Monza return, the Japanese Grand Prix. She was there for all of it.

The 1976 Formula 1 Championship: Lauda vs Hunt Timeline

Marriage and Life Inside Formula 1

Marlene and Niki married in 1976. She entered a world built around Ferrari, Grand Prix events, constant media attention, and the specific atmosphere of top-level motorsport in one of the sport’s most dramatic eras. Archival photography shows her at Formula 1 events during this period. Getty Images includes photographs from the 1977 Dutch Grand Prix and the Swedish Grand Prix. Another dated image from September 10, 1977 identifies her as Marlene Knaus Lauda.

She was present in the Ferrari world, in the paddock, at events across the European Grand Prix calendar during the years when Lauda was arguably the most discussed figure in international motorsport. Those years also included Niki’s second championship with Ferrari in 1977, his retirement in 1979 to build Lauda Air, and eventually his remarkable return to racing with McLaren in 1982. Throughout the later marriage years Lauda was simultaneously managing a significant airline business and, in the 1982 to 1985 period, racing again at the highest level. The demands of that combination on any marriage were considerable.

Their Sons: Lukas and Mathias Lauda

Lukas Lauda

Lukas Lauda was born in 1979, the elder of Marlene and Niki’s two sons. He pursued a career in sports marketing and motorsport management rather than racing himself, though he has remained closely connected to the racing world through his work. He helped manage his brother Mathias’s professional racing career through various stages of its development. In 2024 he entered the Dakar Rally in a Can-Am Maverick with South Racing. The vehicle carried a design inspired by his father’s championship winning McLaren, reflecting a genuine personal connection to his father’s legacy. His professional network also includes connections with KTM and Gottfried Neumeister, who became KTM AG’s chief executive after previously working with Niki Lauda in aviation.

Mathias Lauda

Mathias Lauda was born on January 30, 1981 and followed his father directly into professional racing. His career has covered Formula Nissan, GP2, DTM, NASCAR Whelen Euro Series, and endurance racing. His most significant success came with Aston Martin Racing. In 2017 he competed in the FIA World Endurance Championship’s LMGTE Am class and won the season trophy alongside Pedro Lamy and Paul Dalla Lana. His Aston Martin programme also included Le Mans competition during the 2015 to 2019 period. In one of the more emotionally resonant moments of 2026, Mathias returned to the Austrian Grand Prix at Spielberg and drove his father’s 1975 championship-winning Ferrari 312T during the legends parade. That moment connected three generations of the Lauda name with the sport his father defined.

The Wider Lauda Family

The Lauda family is larger and more complex than just Marlene and her two sons. Niki also had a son named Christoph from a relationship outside his marriage to Marlene. Christoph’s existence is part of the context around the breakdown of the marriage, though Lauda himself was careful in how he described the reasons for the divorce, saying simply that he wanted it and that Marlene accepted it calmly. Niki later married Birgit Wetzinger in 2008. She had donated a kidney to him following his 2018 kidney transplant. They had twins together, Max and Mia. Significantly, Niki described a relationship between his old and new households that went beyond simple separation. He said that Marlene remained part of the wider family life even after his remarriage, reflecting a post-divorce relationship of genuine warmth rather than formal distance.

The Lauda Family: Complete Overview

Why Marlene and Niki Divorced

Marlene and Niki divorced in 1991 after approximately fifteen years of marriage. The 1991 date is well established in Lauda’s biography and obituary records. Niki Lauda spoke about the divorce in his own words. He said that he wanted the separation and described Marlene’s response as calm. He said they remained friends after the divorce, which is reflected in his later descriptions of Marlene remaining connected to the wider family life even after his second marriage.

Formula 1 had placed enormous demands on his time throughout their marriage. The construction and management of Lauda Air added another layer of professional obligation. The existence of Christoph from another relationship was also part of the context around the marriage’s end. Lauda’s own account does not assign blame to Marlene for the breakdown. He took responsibility for wanting the divorce and described her response with evident respect. Specific claims that go beyond that documented explanation, attributing the divorce to particular events, affairs, or confrontations that are not supported by Lauda’s own account, should be treated as speculation rather than fact.

The Divorce: Net Worth and Financial Settlement

No reliable public financial disclosure establishes Marlene Knaus’s personal net worth or the specific terms of her divorce settlement from Niki Lauda. Figures that appear online ranging into tens of millions of dollars should be treated as speculative estimates rather than verified figures. Court records or financial documentation that would establish specific settlement amounts are not part of the public record. What is publicly known is that Niki Lauda built significant business interests across his career, particularly through aviation and his various airline ventures, and that his estimated net worth at the time of his death in 2019 was approximately 200 million dollars. That figure does not automatically establish what Marlene received from their 1991 settlement or what her current personal financial position is.

Marlene Knaus Net Worth: What Different Sources Claim

None of these figures are backed by any verified financial disclosure, court record, or primary source. They should all be treated as rough speculation rather than confirmed fact.

Marlene Knaus in Rush: The Film That Brought Her Story to a New Audience

The 2013 film Rush directed by Ron Howard and written by Peter Morgan brought the 1976 Formula 1 season to a mainstream film audience and introduced Marlene’s story to a new generation. Alexandra Maria Lara played Marlene in the film. Daniel Brühl played Niki Lauda and Chris Hemsworth played James Hunt. The film focuses primarily on the 1976 rivalry between Lauda and Hunt and includes the Nürburgring crash and its aftermath as central dramatic material.

The film uses dramatisation throughout, particularly in its portrayal of personal relationships. Scenes depicting the marriage between Marlene and Niki should be understood as cinematic interpretation rather than documented biographical record. The film’s emotional truth is compelling and it was well received critically, but it is not a documentary and should not be treated as a primary source about Marlene’s actual experience. Alexandra Maria Lara’s performance introduced Marlene’s story to millions of people who were not alive during the 1976 season, which is largely responsible for the sustained search interest in Marlene Knaus that continues into 2026.

Where Is Marlene Knaus Now?

Marlene Knaus has been most reliably associated with Ibiza, Spain in her post-divorce life. Crucially, this is not based on speculation or online rumour. Niki Lauda himself confirmed in a first-hand interview that she lived in Ibiza and that the family had a house on the island. That first-hand confirmation from Niki gives the Ibiza connection considerably more credibility than most claims about her current life.

She maintains a very low public profile. She has no known public social media accounts. She does not give regular interviews. She does not make public appearances that are documented in any consistent way. She is reported to be alive as of 2026. Any credible public report did not support rumours that circulated around 2020 suggesting she had died and should be treated as unfounded. She has not remarried following the 1991 divorce. Her post-divorce life has centred on her family, her connection to Lukas and Mathias, and the continuing link with the wider Lauda family that Niki himself described warmly in interviews.

Final Thoughts

Marlene Knaus moved through the European fashion and social world of the 1970s, was photographed alongside one of that era’s most prominent actors, and then became one of the most recognisable women in Formula 1 through her marriage to the sport’s most technically precise and personally courageous champion. She was there on August 1, 1976 when Niki Lauda’s car caught fire at the Nürburgring. She was there six weeks later when he climbed back into a racing car at Monza with wounds that had not fully healed. She was there through the championship that slipped away in the Japanese rain and through all the years of rebuilding that followed. They built two sons together, Lukas and Mathias, both of whom have carried their father’s name and his connection to motorsport into their own adult lives. The 2026 Austrian Grand Prix, where Mathias drove the 1975 Ferrari 312T in the legends parade, was as clear an image of that continuing legacy as anything. The 2013 film Rush introduced their story to a new generation who were not alive when it happened. That generation has kept searching for Marlene ever since, which is why she continues to generate consistent interest despite giving almost no interviews and maintaining almost no public presence. She lives in Ibiza, confirmed by Niki himself. She has not remarried. She is alive. She is private. That is what is actually known about Marlene Knaus. And for someone who has chosen privacy with such complete and sustained commitment, that is quite enough of a story.
