Who Is Marlene Knaus?
Marlene Knaus is a former model who became famous after she started dating Niki Lauda. Niki was one of the biggest names in Formula 1. He won three world titles and became known around the world.
Marlene was often seen with him during his racing years. She became part of his public life, but she never seemed to enjoy too much attention. Even when cameras followed Niki, Marlene often stayed calm and quiet.
This is one reason people still find her interesting. She lived close to fame, danger, and big racing events, but she still chose to keep much of her life private.
Marlene Knaus Early Life

Young Marlene Knaus and Her Modeling Career
Before her marriage to Niki Lauda, Marlene Knaus worked as a model. She became known for her beauty, simple style, and natural look. Her long loose hair was also one of her most famous features.
During the 1970s, fashion was very different from today. Models often had a soft and simple look. Marlene fitted this style well. Old photos show her wearing clean and classic clothes, often with very little makeup.
Some reports say she worked with well-known brands and appeared in magazines. She was also linked to design work. But her modeling image is the part of her career that people remember the most.
Young photos of Marlene Knaus still get a lot of attention today. Many people find them after watching old Formula 1 clips or the movie Rush.
Marlene Knaus and Curt Jürgens
Before Niki Lauda, Marlene Knaus was linked to famous German-Austrian actor Curt Jürgens. He was a major film and stage star and was much older than Marlene.
The two were seen together in public during the 1970s. Photos show them at social events and other public places. Their relationship ended before Marlene and Niki became a serious couple.
This part of Marlene’s life is important because Curt may have played a small role in how she first crossed paths with Niki. Some reports say Niki met Marlene at a social event connected to Curt.
The exact story is not fully clear. Still, it is widely accepted that Marlene and Niki met around the middle of the 1970s.
How Marlene Knaus Met Niki Lauda
Marlene Knaus and Niki Lauda are believed to have met around 1975. At that time, Niki was already becoming one of the biggest stars in Formula 1.
There are different stories about their first meeting. Some reports say they met at a dinner party. Others say they met at a social event in Salzburg. Because the stories are different, the exact place is hard to confirm.
What is clear is that their relationship became serious very fast. Niki was living a busy life full of races, travel, and media attention. Marlene soon became part of that world.
Imagine meeting someone whose job was to drive at huge speed almost every week. That was the life Marlene entered. It looked exciting from the outside, but it also came with real fear.
Marlene Knaus and Niki Lauda’s Marriage
Marlene Knaus and Niki Lauda married in 1976. Their marriage came at a very important time in Niki’s racing career.
Niki had already won his first Formula 1 world title in 1975. He later won again in 1977 and 1984. This made him one of the greatest drivers of his time.
Being married to a Formula 1 star was not always easy. Niki traveled a lot and raced in dangerous events. Marlene had to live with the fear that something could go wrong at any time.
Still, she supported him and stayed close during some of the hardest years of his life.
Marlene Knaus During Niki Lauda’s 1976 Crash
One of the darkest moments in Niki Lauda’s life came on August 1, 1976. He was racing at the German Grand Prix at the Nürburgring when his Ferrari crashed and caught fire.
Niki was badly burned. He also breathed in very hot and harmful gases. His lungs were badly hurt, and for a short time, people feared he might die.
Marlene Knaus was his wife during this terrible time. Reports say she was deeply worried about the danger of racing. She did not like how risky the sport was, but she still supported Niki.
Niki later spoke warmly about Marlene. He said she stood by him during very hard times. That support became one of the strongest parts of their story.
What happened next was almost unbelievable. Just a few weeks after the crash, Niki returned to racing. Marlene was there as he came back to Formula 1.
His return showed his strong will. It also showed how much pressure Marlene had to live with. She had just watched her husband come close to death, and then he went back into the same dangerous sport.
This is a good place to stop the first half. In the next part, we can continue with Marlene Knaus and her two sons, her divorce from Niki Lauda, her life after the marriage, her role in Rush, her net worth, and where she is today in 2026.
Marlene Knaus and Her Two Sons
Marlene Knaus and Niki Lauda had two sons together. Their names are Lukas Lauda and Mathias Lauda. Both sons later stayed close to the world of racing in different ways.
Mathias Lauda followed his father into motorsport. He became a racing driver and built his own career. He also won the 2017 FIA World Endurance Championship title in the LMGTE Am class. This was a big moment for him.
Lukas Lauda chose another path. He worked more on the business and management side of racing. He has also helped manage his brother Mathias. This means both sons stayed linked to the sport that made their father famous.
Some reports also say Marlene and Niki lost a baby during their marriage. This is a very personal and sad part of their family story. Because it is a private matter, it is best to mention it with care.
Why Did Marlene Knaus and Niki Lauda Divorce?
Marlene Knaus and Niki Lauda divorced in 1991. They had been married for about 15 years. Their marriage had gone through fame, travel, racing danger, family life, and many hard moments.
The exact reason for the divorce was never clearly shared by Marlene or Niki. This is important because many websites try to give one simple reason. In truth, the full story stayed private.
Niki also had a son named Christoph from a relationship outside the marriage. Some reports say this caused stress in the marriage. Still, it would not be fair to say this alone caused the divorce.
What we do know is that Marlene Knaus stayed with Niki for years after this became known. Their marriage ended later, in 1991. So the real reason may have been more complex than one event.
Marlene Knaus After the Divorce
After the divorce, Marlene Knaus moved away from the public eye. She had never been someone who chased fame, and after 1991 she became even more private.
She did not build a new public career or spend much time in interviews. There is also no strong public record showing that she remarried. Most reports say she chose a quiet life.
What makes this more interesting is that Marlene and Niki reportedly stayed on good terms. Some people close to their story have said they remained very close even after the marriage ended.
This shows that divorce did not fully break their family bond. They still shared two sons and many years of memories together.
Marlene Knaus in Rush
Many younger fans learned about Marlene Knaus through the 2013 movie Rush. The film tells the story of the famous Formula 1 fight between Niki Lauda and James Hunt.
In the movie, actress Alexandra Maria Lara plays Marlene Knaus. Daniel Brühl plays Niki Lauda, while Chris Hemsworth plays James Hunt.
The film shows Marlene as an important person in Niki’s life, especially during his racing years and after his crash. It helps viewers understand how much pressure their relationship faced.
Still, Rush is a movie, not a full history book. Some scenes were made more dramatic for the screen. So fans should not believe every part of the movie happened exactly that way in real life.
Marlene herself did not act in the film. She was played by Alexandra Maria Lara. This is useful to know because some people search for “Marlene Knaus movies” and may get confused.
