Martin Winterkorn

Martin Winterkorn (born 24 May 1947) is a German former business executive who served as chairman of the board of management (CEO) of Volkswagen AG, the parent company of the Volkswagen Group, from 2007 to 2015. Under his leadership, Volkswagen pursued an aggressive "Strategy 2018" designed to make the company the world's largest automaker, surpassing Toyota and General Motors. This ambition was achieved in 2016, but Winterkorn's tenure ended in disgrace when the Volkswagen emissions scandal - commonly known as "Dieselgate" - revealed that Volkswagen had systematically installed software in millions of diesel vehicles to cheat emissions tests, deceiving regulators and consumers worldwide.

The emissions scandal, exposed in September 2015, represented one of the largest corporate frauds in automotive history. Volkswagen admitted that approximately 11 million vehicles worldwide contained "defeat devices" - software that detected when vehicles were undergoing emissions testing and temporarily reduced nitrogen oxide (NOx) emissions to pass tests, while emitting up to 40 times the legal limit of pollutants during normal driving. The fraud violated environmental regulations across multiple countries and jurisdictions, resulting in tens of billions of dollars in fines, settlements, vehicle recalls, and legal costs.

Winterkorn resigned as Volkswagen CEO on 23 September 2015, just days after the scandal became public. He accepted responsibility for the emissions fraud while asserting that he was "not aware of any wrongdoing on my part." He was subsequently criminally indicted in both the United States (May 2018) and Germany (April 2019) on charges including fraud, conspiracy, and market manipulation. Because Germany does not extradite its citizens to non-EU countries, Winterkorn remains safe from American prosecution as long as he stays within German borders, effectively making him a fugitive from U.S. Justice.

Prior to leading Volkswagen, Winterkorn served as CEO of Audi AG from 2002 to 2006, where he was credited with elevating the brand's prestige and engineering excellence. His career at Volkswagen Group spanned more than two decades, with expertise in quality assurance and technical development. By 2014, he was the highest-paid CEO of any company listed on Germany's DAX blue-chip stock index.

Early life and education

Background and childhood

Martin Winterkorn was born on 24 May 1947 in Leonberg, a town in the Württemberg-Baden region of what is now the German state of Baden-Württemberg. He grew up in postwar Germany during the country's "Wirtschaftswunder" (economic miracle), when West Germany rapidly rebuilt its industrial base and automotive sector following World War II.

Little public information exists about Winterkorn's family background, as he has maintained strict privacy regarding personal matters throughout his career. This reticence extended to virtually all aspects of his private life, with colleagues describing him as intensely private and focused almost exclusively on his professional responsibilities.

Education

Winterkorn pursued higher education in metallurgy and metal physics at the University of Stuttgart from 1966 to 1973. The University of Stuttgart, one of Germany's leading technical universities, had particular strength in engineering and materials science - disciplines essential to the automotive industry that would define Winterkorn's career.

After completing his studies at Stuttgart, Winterkorn continued his academic training at the Max Planck Institute for Metal Research and Metal Physics, one of Germany's premier scientific research institutions. He completed his doctoral dissertation there in 1977, receiving his Ph.D. In metal physics. This rigorous scientific background would inform his later emphasis on quality assurance, materials engineering, and technical precision in automotive manufacturing.

During his student years, Winterkorn played football as a goalkeeper, an activity that provided physical outlet from demanding academic work. Sports connections would later feature in his career through his long association with Bayern Munich football club.

Early career

Robert Bosch GmbH (1977-1981)

Winterkorn began his professional career in 1977 at Robert Bosch GmbH, the German engineering and technology company that was then and remains today one of the world's largest automotive component suppliers. At Bosch, he worked as a specialist assistant in the research division "Process Engineering," applying his doctoral training in metallurgy to industrial applications.

From 1978 to 1981, Winterkorn headed the refrigerant compressor development group "Substances and Processes" at Robert Bosch and the joint venture Bosch-Siemens-Hausgeräte GmbH. This management experience in research and development established foundations for his later quality assurance and engineering roles in the automotive industry.

Audi AG (1981-1993)

In 1981, Winterkorn joined Audi AG, beginning a relationship with the Volkswagen Group that would span more than three decades. He entered as assistant to the Member of the Board for Quality Assurance, immersing himself in the systems and standards that governed automotive manufacturing quality.

Two years later, in 1983, Winterkorn assumed responsibility for "Measuring Technology/Sampling and Test Laboratory" at Audi, a technical role focused on the precision measurement and testing processes essential to quality control. At the beginning of 1988, he was promoted to departmental head of "Central Quality Assurance," and in 1990 became Head of Audi Quality Assurance.

This progression through quality assurance roles developed Winterkorn's reputation as a detail-oriented, technically rigorous executive who demanded exacting standards. Quality assurance represented a critical function in premium automotive manufacturing, where brand reputation depended on reliability and craftsmanship. Winterkorn's success in this area would lead to broader responsibilities across the Volkswagen Group.

Volkswagen AG quality and technical leadership (1993-2002)

In 1993, Winterkorn moved from Audi to the parent company Volkswagen AG as head of Group Quality Assurance. This position gave him responsibility for quality standards across the entire Volkswagen Group portfolio of brands. In March 1994, he was appointed General Manager of Volkswagen AG with power of attorney, expanding his corporate authority.

From June 1995, Winterkorn additionally took responsibility for VW Group Product Management, adding strategic product planning to his quality oversight role. In January 1996, he became Member of the Brand Board of Management for "Technical Development" for the Volkswagen brand, replacing Herbert Schuster in this critical engineering leadership position.

From July 2000, Winterkorn served as Member of the VW Group Board of Management for Technical Development, responsible for engineering and development across all Group brands. This executive board position placed him at the center of Volkswagen's product strategy and technological direction.

During this period, Winterkorn was instrumental in championing the New Beetle project, persuading then-CEO Ferdinand Piëch to approve production of the retro-styled vehicle that would become a commercial success and cultural phenomenon in the late 1990s and early 2000s.

Audi CEO (2002-2006)

Leadership and brand development

On 1 March 2002, Winterkorn was appointed Chairman of the Board of Management of Audi AG, effectively becoming CEO of the premium brand. He assumed leadership of the newly formed Audi brand group, which included the SEAT and Lamborghini brands under common management from 1 January 2002.

With effect from 1 January 2003, Winterkorn also assumed direct responsibility for Technical Development at Audi AG, combining the CEO role with hands-on engineering leadership. In his capacity as CEO of Audi, he simultaneously served as a Member of the Board of Management of Volkswagen AG.

Under Winterkorn's leadership, Audi continued its transformation from a respected but second-tier German automaker into a genuine competitor to BMW and Mercedes-Benz in the global luxury vehicle market. The brand's "Vorsprung durch Technik" (Advancement through Technology) positioning aligned with Winterkorn's engineering-focused management approach.

Technical innovations

Winterkorn championed Audi's technological differentiation, supporting development of the brand's quattro all-wheel-drive systems, lightweight aluminum construction (particularly in the Audi A8), and advanced diesel engine technology. TDI (turbocharged direct injection) diesel engines became a cornerstone of Audi's identity, offering performance combined with fuel efficiency that appealed to European consumers.

Ironically, it was precisely this diesel technology emphasis - extended across the Volkswagen Group under Winterkorn's later leadership - that would become central to the emissions scandal. The engineering culture that Winterkorn cultivated prized performance metrics and competitive benchmarking, creating pressure to achieve emissions and efficiency targets that may have contributed to the eventual fraud.

Bayern Munich board membership

From 22 February 2003, concurrent with his Audi CEO role, Winterkorn served on the board of supervisors for FC Bayern Munich, Germany's most successful football club. This position reflected the traditional partnership between major German corporations and prominent football clubs, and specifically the commercial relationship between Audi and Bayern Munich.

Winterkorn is credited with fostering a successful partnership between Audi and Bayern Munich, with the automaker becoming a major sponsor and shareholder in the club. He served on the Bayern Munich board until 18 December 2018, well after his departure from Volkswagen, though his resignation from the football club followed the continued fallout from the emissions scandal.

Recognition

Since June 2003, Winterkorn has served as an honorary professor of the Budapest University of Technology and Economics, in recognition of his service to the promotion of research at the establishment. This academic connection reflected his technical background and continued interest in engineering education.

He was featured in the Power List of American automotive magazine Motor Trend in both 2007 and 2008, recognition of his influence in the global automotive industry as he transitioned from Audi to Volkswagen Group leadership.

Volkswagen Group CEO (2007-2015)

Appointment and "Strategy 2018"

Winterkorn succeeded Bernd Pischetsrieder as CEO of Volkswagen AG on 1 January 2007. He inherited a company that was already one of the world's largest automakers but aspired to become the absolute largest.

Shortly after assuming the CEO position, Winterkorn unveiled "Strategy 2018" - an ambitious plan to make Volkswagen the world's largest automaker by 2018, surpassing both Toyota and General Motors in global vehicle sales. The strategy emphasized growth in emerging markets, expansion of the vehicle lineup, and technological leadership in areas including efficiency and emissions performance.

The strategy reflected Winterkorn's competitive drive and detail-oriented management style. He established specific quantitative targets across the organization, creating pressure to achieve measurable improvements in sales, quality, and efficiency. This target-driven culture would later be cited as a contributing factor to the emissions fraud, though the direct connection between Strategy 2018 and the defeat device remains debated.

Platform standardization

Among Winterkorn's most significant strategic initiatives was the development of standardized vehicle platforms - specifically the MQB (Modular Transverse Matrix) and MLB (Modular Longitudinal Matrix) architectures. These platforms standardized the area between the accelerator pedal and front wheels, including engines and transmissions, where approximately 60% of vehicle development costs occur.

The platform strategy allowed Volkswagen Group to reduce development costs dramatically while increasing design flexibility for the rest of each vehicle. Models across Volkswagen, Audi, SEAT, Škoda, and other brands could share common mechanical underpinnings while maintaining distinct identities and price positioning. This approach proved highly successful commercially and was widely imitated by competitors.

Management style

Within the Volkswagen Group, Winterkorn was known for intense attention to detail, being described as "product-focused," "methodical and precise," but also extremely demanding. He was famous for personally inspecting vehicles at auto shows and development presentations, testing panel gaps with his fingernail, checking paint quality, and scrutinizing every detail of interior finish.

This obsessive quality focus drove improvements in Volkswagen vehicles but also created a culture of fear among subordinates, according to later accounts. Executives reportedly dreaded presentations to Winterkorn, knowing that any flaw would be identified and criticized. This pressure-cooker environment may have discouraged bad news from flowing upward and created incentives to achieve targets by any means necessary.

Growth and success

Under Winterkorn's leadership, Volkswagen Group achieved remarkable commercial success. Sales grew substantially across most regions, with particular success in China, which became Volkswagen's largest single market. The company acquired or strengthened relationships with various brands, including the full integration of Porsche into the Group.

By 2014, Winterkorn was the highest-paid CEO of any company listed on Germany's DAX blue-chip stock index, reflecting both Volkswagen's success and the compensation structures common in German industry. His total compensation packages during peak years reached tens of millions of euros.

Achievement of Strategy 2018 goals

The ambition to become the world's largest automaker was actually achieved ahead of schedule - though the victory was hollow. In early 2015, before the emissions scandal became public, Volkswagen passed Toyota in global vehicle sales for the first time. The triumph represented vindication of Strategy 2018 and Winterkorn's aggressive growth targets.

However, within months, the company's reputation would be shattered by revelations of systematic fraud that undermined the very technological leadership claims on which the growth had been built.

Volkswagen emissions scandal

Discovery and exposure

The Volkswagen emissions scandal originated from academic research that revealed unexplained discrepancies between diesel vehicles' laboratory emissions results and their real-world performance. Researchers at West Virginia University, working with the International Council on Clean Transportation, conducted on-road emissions testing of Volkswagen diesel vehicles in 2014 and found that nitrogen oxide (NOx) emissions during actual driving were 5 to 35 times higher than during laboratory testing.

These findings were communicated to the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB), which began investigating. Volkswagen initially offered various technical explanations for the discrepancies, but these explanations proved inadequate. After more than a year of back-and-forth with regulators, Volkswagen finally admitted in September 2015 that it had installed "defeat devices" - software that detected when vehicles were undergoing emissions testing and activated emissions controls, while allowing vehicles to pollute freely during normal driving.

Scale of the fraud

The admission revealed fraud of extraordinary scope. Approximately 11 million vehicles worldwide contained the defeat device software, including approximately 500,000 vehicles sold in the United States and far larger numbers in Europe and other markets. The affected vehicles included multiple model years across Volkswagen, Audi, SEAT, and Škoda brands - essentially the full range of vehicles using the company's EA 189 diesel engine family.

The defeat devices allowed vehicles to pass laboratory emissions tests while emitting up to 40 times the legal limit of nitrogen oxides during actual driving. NOx emissions contribute to respiratory diseases, smog, and environmental damage. The health impact of the excess emissions, while difficult to quantify precisely, was estimated by some researchers to have contributed to thousands of premature deaths globally.

Winterkorn's response and resignation

On 20 September 2015, Winterkorn released a video statement apologizing for the emissions fraud and promising a thorough investigation. He stated: "I personally am deeply sorry that we have broken the trust of our customers and the public. We will cooperate fully with the responsible agencies."

However, Winterkorn's initial response emphasized that the fraud was the work of "a few people" and did not accept personal knowledge or responsibility. He blamed "the terrible mistakes of a few people" without naming them, suggesting the fraud had occurred without senior management's awareness.

On 23 September 2015, just three days after his initial apology, Winterkorn resigned as CEO of Volkswagen AG. His resignation statement accepted responsibility as CEO while denying personal involvement: "I am shocked by the events of the past few days. Above all, I am stunned that misconduct on such a scale was possible in the Volkswagen Group. As CEO, I accept responsibility for the irregularities that have been found in diesel engines and have therefore requested the Supervisory Board to agree on terminating my function as CEO of the Volkswagen Group. I am doing this in the interests of the company even though I am not aware of any wrongdoing on my part."

Winterkorn additionally resigned as chairman of the Audi supervisory board on 11 November 2015, following additional revelations that emissions test manipulation had extended to some gasoline-powered vehicles in addition to the diesel engines at the center of the original scandal.

Financial impact on Volkswagen

The emissions scandal proved enormously costly for Volkswagen. The company has paid approximately €30 billion (over $30 billion) in fines, legal costs, vehicle buybacks, and settlements, primarily in the United States where regulatory penalties and class action litigation created the largest exposure.

In the United States alone, Volkswagen agreed to pay approximately $25 billion to settle civil claims, including funds to buy back affected vehicles from owners, compensate owners who chose to keep their vehicles, fund environmental remediation, and support electric vehicle infrastructure development. The company also paid substantial criminal fines and agreed to external compliance monitoring.

European financial exposure proved lower due to different regulatory structures and less aggressive litigation cultures, though various countries pursued penalties and affected vehicle owners have sought compensation through national legal systems.

Criminal prosecutions

United States indictment

On 3 May 2018, Martin Winterkorn was indicted by a federal grand jury in the United States on charges of fraud and conspiracy related to the emissions scandal. U.S. Attorney General Jeff Sessions announced the charges, stating: "If you try to deceive the United States, then you will pay a heavy price."

The indictment charged Winterkorn with conspiracy to defraud the United States, conspiracy to commit wire fraud, conspiracy to violate the Clean Air Act, and multiple counts of wire fraud. The charges carried potential prison sentences of decades if convicted.

Critically, the indictment alleged that Winterkorn had been briefed on the defeat device software and approved its continued concealment from U.S. Regulators at a 2015 business conference in Wolfsburg, Germany. The indictment referenced emails from Oliver Schmidt, Volkswagen's then-compliance liaison who had already pleaded guilty in the case and received a seven-year prison sentence.

Because Germany does not extradite its own citizens to countries outside the European Union, Winterkorn cannot be prosecuted in the United States unless he voluntarily leaves German territory. He effectively became a fugitive from American justice, wanted by the Environmental Protection Agency and the Department of Justice but unreachable as long as he remains in Germany.

German prosecution

On 15 April 2019, German regional prosecutors in Braunschweig charged Winterkorn with fraud, violation of laws prohibiting unfair competition, and Untreue (defalcation or breach of fiduciary duty). The German charges related to his alleged failure to inform investors and capital markets in good time after learning about the emissions fraud, in addition to the underlying fraud itself.

The German prosecution alleged that Winterkorn knew about the defeat devices earlier than he claimed - specifically, that he learned about them before September 2015 but failed to disclose this information to shareholders and regulators as required by German securities law. Winterkorn has maintained that he only learned about the defeat devices in September 2015 when the scandal became public.

Prosecutors in Stuttgart separately investigated market manipulation claims but ultimately deferred to the Braunschweig case.

Repeated trial delays

The German criminal trial was originally scheduled to begin in 2021, but proceedings against Winterkorn were separated from those against other defendants and repeatedly postponed due to his reported poor health.

The trial finally began on 3 September 2024 - nine years after the scandal emerged. Winterkorn appeared in court but proceedings were again suspended in October 2024 after Winterkorn reportedly slipped in the shower at his home and broke his right leg. The court indicated that he would be unable to participate in hearings for several months.

As of 2025, the trial remains suspended with restart expected sometime in 2025, though Winterkorn's age (77) and health issues raise questions about whether the proceedings will ever reach conclusion.

Denials and defense

Throughout the legal proceedings, Winterkorn has consistently denied knowledge of or responsibility for the emissions fraud. In February 2024 testimony, he stated: "I have neither requested nor encouraged this functionality, nor condoned its use."

His defense has emphasized that he was "neither an engine specialist nor a software expert," suggesting that technical details of the defeat device would not have been brought to his attention through normal corporate communications. He has described the accusations against him as "inconceivable."

Settlement with Volkswagen

Separate from criminal proceedings, Winterkorn reached a civil settlement with Volkswagen in 2021 under which he agreed to pay approximately €11-12 million to the company. This settlement resolved Volkswagen's internal claims against former executives for breach of duty, though it did not affect criminal liability.

In January 2020, reports indicated that the German judge in the case suggested Winterkorn might be allowed to retain approximately $12 million in bonuses and potentially avoid conviction, though these reports reflected preliminary observations rather than final rulings.

Personal life

Family

Martin Winterkorn is married to Anita Winterkorn. The couple has two children, though Winterkorn has maintained strict privacy about his family throughout his career, and little public information exists about his children or grandchildren.

Colleagues have consistently described Winterkorn as intensely private, keeping personal matters completely separate from his professional life. Even during his years of corporate prominence as Volkswagen CEO, he rarely discussed family or personal interests in interviews, maintaining focus on business matters.

Residence

During his Volkswagen career, Winterkorn was based in Wolfsburg, Germany, the company's headquarters city. Following his resignation and the ongoing legal proceedings, he has remained in Germany to avoid exposure to American prosecution.

Net worth

Estimates of Winterkorn's net worth following the emissions scandal and various settlements range from approximately $30 million to $50 million. His wealth derives from executive compensation during his years as Audi and Volkswagen CEO (when he was Germany's highest-paid DAX executive), retained retirement benefits and pension arrangements, and investments accumulated during his career.

The 2021 settlement with Volkswagen required him to return approximately €11-12 million, reducing his net worth, though he retained substantial assets. The ongoing legal proceedings and potential fines could further affect his financial position depending on trial outcomes.

Legacy

Impact on Volkswagen

Winterkorn's legacy at Volkswagen is inextricably bound to the emissions scandal. While he oversaw significant commercial success and the achievement of Strategy 2018's goal of becoming the world's largest automaker, these accomplishments were overshadowed by the fraud that emerged during his final months as CEO.

The scandal fundamentally damaged Volkswagen's reputation for engineering excellence and environmental responsibility - precisely the values that had underpinned the "clean diesel" marketing campaigns at the heart of the fraud. The company has since pivoted toward electric vehicles and attempted to rebuild trust, but the Dieselgate brand damage persists.

Impact on automotive industry

The Volkswagen emissions scandal triggered fundamental changes in how automotive emissions are regulated and tested. Regulatory agencies worldwide implemented more rigorous real-world driving emissions (RDE) testing protocols to complement or replace laboratory testing that had proven susceptible to manipulation.

The scandal also accelerated the automotive industry's pivot toward electric vehicles. With diesel technology tainted by the fraud, many manufacturers reduced investment in diesel development and increased focus on battery electric and hybrid propulsion systems. Some analysts argue that Dieselgate effectively ended diesel's viability as a mainstream passenger vehicle technology in many markets.

Accountability questions

The drawn-out legal proceedings against Winterkorn have raised questions about corporate accountability and the ability of legal systems to hold senior executives responsible for organizational misconduct. Nine years after the scandal, Winterkorn has not been convicted of any crimes, and his advanced age and health issues may prevent the German trial from reaching conclusion.

Critics argue that the delay and uncertainty demonstrate that powerful executives can effectively evade accountability through legal maneuvering and health claims. Others note that civil settlements, the destruction of his reputation, and the functional restrictions on his international travel represent meaningful consequences even without criminal conviction.
