Herbert Diess
Herbert Diess (born 24 October 1958) is an Austrian businessman and engineer who served as chairman of the board of management of Volkswagen Group from 2018 to 2022, leading one of the world's largest automakers through its most ambitious and turbulent transformation. Tasked with steering Volkswagen away from the catastrophic Dieselgate emissions scandal and toward an electric future, Diess launched a radical €89 billion electrification strategy that positioned VW as Tesla's most serious European challenger while simultaneously alienating the company's powerful labor unions, triggering bitter conflicts with the works council, and ultimately leading to his forced resignation in July 2022.
Diess was a polarizing figure who combined visionary strategic thinking with a confrontational management style that proved incompatible with Volkswagen's consensus-driven culture. He forged an unlikely friendship with Elon Musk, invited the Tesla CEO to speak to VW executives, and openly praised Tesla as the industry benchmark—moves that infuriated VW's unions and supervisory board. His warnings that Volkswagen needed to cut 30,000 jobs to remain competitive sparked fury from labor leaders, while delays and cost overruns in the Cariad software division—for which he was personally responsible—gave his enemies ammunition to force him out. Despite being named one of the "Best CEOs in the World" in 2018 and successfully launching the ID electric vehicle family, Diess lasted just four years as CEO, becoming the fourth consecutive Volkswagen chief executive to be ousted by the company's unique power-sharing structure between management, unions, and controlling families.
After his departure from Volkswagen, Diess resurfaced as chairman of semiconductor giant Infineon Technologies and executive chairman of electromobility company The Mobility House, continuing his mission to accelerate the automotive industry's transition to sustainable mobility. His tenure at Volkswagen stands as a case study in the challenges of transforming legacy industrial giants, the limits of visionary leadership in heavily unionized environments, and the culture clash between Silicon Valley-style disruption and traditional German corporate governance.
Early life and education
Herbert Diess was born on 24 October 1958 in Munich, Germany. He grew up in a middle-class family during West Germany's postwar economic boom, developing an early fascination with automotive technology and engineering. Details about his parents and childhood have been kept largely private, as Diess maintained a low public profile regarding his personal background throughout his career.
Diess pursued his passion for automotive engineering academically, studying vehicle technology at Munich University of Applied Sciences starting in 1977. He continued his education at Munich Technical University (Technische Universität München), one of Germany's premier engineering institutions, where he earned a degree in mechanical engineering in 1983. His academic excellence and research capabilities led him to pursue doctoral studies, and in 1987 he completed his Ph.D. in the field of assembly automation, focusing on manufacturing efficiency and production processes—expertise that would later prove central to his career in the automotive industry.
The rigorous German engineering education system instilled in Diess both deep technical knowledge and a systematic approach to problem-solving that characterized his later management philosophy. However, his academic background also contributed to what critics would later describe as an overly analytical, numbers-driven leadership style that sometimes failed to account for the human and political dimensions of corporate management.
Personal life
Herbert Diess is married to Irene Diess, and the couple has at least one son, Andreas Diess. Unlike many high-profile CEOs, Diess has maintained remarkable privacy around his family life, with almost no public information available about how he met his wife, their relationship history, or details about their family dynamics. This discretion stands in stark contrast to his very public role leading one of the world's largest corporations and his active presence on social media platforms like Twitter.
The Diess family has reportedly lived in the Munich area for much of Herbert's career, though he maintained residences near Volkswagen's Wolfsburg headquarters during his tenure with the company. Irene Diess has occasionally appeared with Herbert at formal corporate events, including automotive industry galas and Volkswagen shareholder meetings, but she has never given interviews or maintained any public profile independent of her husband's corporate position.
The privacy surrounding Diess's personal life is typical of German executive culture, which tends to maintain stricter boundaries between public corporate roles and private family matters than is common in American or British business circles. This discretion served Diess well during his controversial tenure at Volkswagen, as his opponents focused their criticisms on his management decisions rather than personal matters.
Career
Robert Bosch (1989-1996)
Diess began his industrial career at Robert Bosch, one of the world's largest suppliers of automotive components and industrial technology. In 1990, he moved to Spain, where he was appointed Technical Director for Planning and Maintenance at Bosch's plant in Treto, a facility specializing in automotive electronics and braking systems. The Spanish assignment provided Diess with international experience and exposed him to manufacturing operations outside Germany's highly regulated labor environment.
His performance in Spain earned him rapid promotion, and he later became General Manager of the Treto plant, gaining hands-on experience in managing large-scale manufacturing operations, labor relations, and cost optimization—skills that would become hallmarks of his later career. The Bosch years gave Diess a supplier's perspective on the automotive industry, understanding the cost pressures and efficiency demands that OEMs (original equipment manufacturers) imposed on their vendor networks.
BMW (1996-2015)
In 1996, Diess joined BMW AG in Munich as Director of Long-Term and Structural Planning, returning to his hometown and entering one of Germany's most prestigious automotive companies. Over nearly two decades at BMW, Diess rose through the engineering and technology divisions, taking on increasingly senior roles in product development and manufacturing.
His most significant contribution at BMW came through his leadership in developing the company's electric vehicle strategy. Diess was widely credited as one of the key figures behind the BMW i3, the company's breakthrough urban electric vehicle launched in 2013, and the BMW i8, a plug-in hybrid sports car that combined futuristic design with advanced powertrain technology. These vehicles positioned BMW as a pioneer in premium electric mobility, years ahead of most traditional automakers.
Diess's work on the i-series demonstrated his vision for electric vehicles and sustainable mobility, but also his willingness to champion expensive, risky projects that didn't immediately generate profits. The i3 in particular was a commercial disappointment, selling far fewer units than projected and never recouping its massive development costs. This experience foreshadowed the tensions Diess would later face at Volkswagen, where ambitious electrification plans collided with financial realities and stakeholder expectations.
At BMW, Diess also developed a reputation as a cost-cutter and efficiency expert, identifying manufacturing redundancies and pushing for streamlined production processes. These skills made him attractive to Volkswagen, which was seeking outside talent to shake up what many viewed as a complacent corporate culture.
Volkswagen Group
Arrival and Dieselgate (2015-2018)
Herbert Diess joined Volkswagen in July 2015 as head of the Volkswagen passenger car brand, lured from BMW specifically to inject new ideas, technology expertise, and cost discipline into the company. His appointment was part of a broader effort by VW to bring in outside talent and reduce the company's insularity. Ironically, Diess arrived just two months before the Dieselgate scandal exploded in September 2015, instantly making his job far more difficult than anyone had anticipated.
The Dieselgate scandal—in which Volkswagen had intentionally programmed diesel engines to cheat on emissions tests, causing vehicles to emit up to 40 times the legal limit of nitrogen oxides in real-world driving—became the largest corporate fraud in automotive history. The scandal predated Diess's arrival, having been orchestrated by previous management, but he was immediately tasked with managing the fallout. As of June 2020, Dieselgate had cost Volkswagen $33.3 billion in fines, penalties, financial settlements, and buyback costs, devastating the company's finances and reputation.
Diess's role in managing the crisis was complicated. He was untainted by involvement in the scandal itself, lending him credibility, but he also lacked the internal networks and political capital to navigate VW's complex governance structure. He pushed for aggressive cost-cutting to offset the financial damage, immediately putting him at odds with the powerful IG Metall labor union and the works council, which held half the seats on Volkswagen's supervisory board.
During this period, Diess began articulating a vision for Volkswagen's future that went far beyond crisis management. He argued that Dieselgate, while catastrophic, also presented an opportunity to fundamentally transform the company, pivoting from internal combustion engines to electric vehicles and reimagining Volkswagen for the 21st century. This message resonated with the supervisory board and the Porsche and Piëch families who controlled VW through their voting shares, leading to Diess's promotion.
CEO and the electric revolution (2018-2022)
In April 2018, Diess was named CEO of the entire Volkswagen Group, overseeing not just the VW brand but also Audi, Porsche, SEAT, Škoda, Lamborghini, Bentley, and the company's commercial vehicle divisions. He was named one of the "Best CEOs in the World" by CEOWORLD magazine that year, recognition of his bold vision and the enormity of the challenge he faced.
Diess immediately launched the most ambitious electrification program in automotive history. The strategy, ultimately totaling €89 billion in planned investments through 2025, aimed to develop a family of electric vehicles on the modular MEB (Modularer E-Antriebs-Baukasten) platform, convert the Zwickau plant in Germany to all-electric production, and position Volkswagen to build 1.5 million electric vehicles annually by 2025. The centerpiece was the ID family of electric vehicles—ID.3, ID.4, ID.5, ID. Buzz—designed to bring electric mobility to the mass market at affordable prices.
The ID.3, launched in 2020, was envisioned as VW's "electric Golf"—a vehicle for ordinary families that would do for electric cars what the original Beetle and Golf had done for internal combustion. The ID.4 SUV followed, targeting the crucial American and Chinese markets. By 2022, Volkswagen had become the second-largest seller of electric vehicles in Europe (behind Tesla) and third-largest globally (behind Tesla and BYD of China), validating Diess's strategic vision.
However, the electric transformation came with enormous challenges. The upfront costs were staggering, depressing profitability in the short term. Traditional VW dealers were unenthusiastic about selling electric vehicles, which required less service and generated lower aftermarket revenue. And most problematically, Volkswagen's software capabilities proved wholly inadequate for the connected, over-the-air-updatable vehicles that customers now expected.
The Cariad disaster
To address the software problem, Diess created Cariad, a consolidated software division that was supposed to develop a unified operating system for all Volkswagen Group brands. He took personal responsibility for Cariad, betting his reputation on the new unit's ability to deliver. It was a catastrophic miscalculation.
Cariad was plagued by delays, cost overruns, and an inability to deliver promised features. The division's failures delayed key vehicle launches at Porsche, Audi, and Bentley for years, causing friction between VW Group brands. Software bugs in early ID vehicles generated customer complaints and damaged the electric vehicle rollout. By 2022, Cariad had consumed billions in investment with little to show for it, and Diess's personal championing of the division made him directly culpable for its failures.
The Cariad debacle provided ammunition to Diess's critics, who argued that his grand strategic vision was disconnected from operational reality. Volkswagen's supervisory board, unions, and brand executives increasingly viewed Diess as a liability rather than an asset.
Labor conflicts and the works council
Diess's relationship with Volkswagen's works council—the elected employee representation that holds enormous power in German corporate governance—was toxic almost from the beginning. The conflict reached a crisis point in late 2021 when, at a supervisory board meeting, Diess announced that Volkswagen's core brand had 30,000 excess employees in Germany and that "one in four jobs would be superfluous" if the company failed to improve productivity.
The statement, immediately leaked to the media, ignited a firestorm. Daniela Cavallo, head of the works council, accused Diess of fear-mongering and damaging employee morale. IG Metall, Germany's powerful metalworkers union, demanded Diess's removal. The supervisory board, on which the works council held 10 of 20 seats, sided with labor, stripping Diess of direct control over the VW brand and placing him under supervision.
The fundamental issue was Diess's management philosophy, which prioritized efficiency, speed, and transformation over consensus and job security. In American or British corporate culture, a CEO warning of excess headcount might be seen as responsible stewardship. In Germany's codetermination system, where labor legally shares corporate governance, it was viewed as a declaration of war.
Diess's confrontational style—demanding rapid change, publicly criticizing underperformance, setting aggressive targets—clashed with Volkswagen's culture of consensus and incremental progress. Former colleagues described him as "visionary but impatient," "strategically brilliant but tactically tone-deaf," and "the right diagnosis but the wrong doctor."
The Elon Musk connection
Adding fuel to the fire was Diess's public admiration for Elon Musk and Tesla. In 2020, Diess invited Musk to virtually address 200 of Volkswagen's top executives, an unprecedented move that outraged many within the company. Diess praised Tesla's software capabilities, manufacturing efficiency, and corporate agility, using the competitor as a benchmark to shame VW into faster action.
Diess and Musk developed a genuine friendship, engaging in public Twitter exchanges where they playfully challenged each other. In 2019, Musk tweeted that Diess was "doing more than any major carmaker to go electric." Diess responded by calling Musk "a brilliant person who is changing the world." In January 2021, Diess made his Twitter debut with a post that teased Musk: "I want to get some of your market shares."
The mutual admiration was sincere but politically catastrophic for Diess. The works council viewed his Tesla fandom as disloyalty to Volkswagen and its workforce. Union leaders demanded Diess "stop obsessing over Musk," calling his praise for the competition "damaging to the business." The Porsche and Piëch families, who controlled Volkswagen, were reportedly irritated by Diess's public embrace of an American disruptor who represented everything traditional German engineering was not.
For Diess, the Musk relationship represented a genuine belief that Volkswagen needed to learn from Tesla's speed, innovation, and risk tolerance. For his critics, it was evidence that Diess didn't understand or respect Volkswagen's culture and traditions.
The ouster (July 2022)
By early 2022, Diess's position had become untenable. The works council opposed him, Cariad's failures had alienated brand executives, and the Porsche and Piëch families—who held controlling voting shares through their holding company—had lost confidence. In July 2022, while Diess was on a business trip to the United States, the families plotted his removal.
On 22 July 2022, Volkswagen's supervisory board voted unanimously to terminate Diess's contract, announcing that Porsche CEO Oliver Blume would replace him effective 1 September 2022. The decision was presented as mutual and amicable, but reporting later revealed it was a boardroom coup orchestrated while Diess was out of the country.
The official explanation cited "strategic differences" and the need for "different leadership." Blume, a Volkswagen veteran with deep roots in German automotive culture and strong relationships with the works council, represented everything Diess was not: consensus-oriented, diplomatic, and committed to evolutionary rather than revolutionary change.
Diess became the fourth consecutive Volkswagen CEO to be forced out, following Martin Winterkorn (Dieselgate), Matthias Müller (ineffective crisis management), and now Diess himself (cultural incompatibility). The pattern suggested something systemic about Volkswagen's governance structure that made sustained CEO tenure nearly impossible.
Industry observers were divided on Diess's legacy. Supporters argued he had saved Volkswagen by forcing a necessary electric transformation that more diplomatic leaders would have delayed. Critics contended his confrontational style poisoned relationships and that a more skillful leader could have achieved the same strategic goals without the organizational chaos.
Post-Volkswagen career
Diess officially departed Volkswagen on 1 September 2022, receiving a severance package that brought his 2023 compensation from VW to €11.2 million—ironically more than his successor Oliver Blume earned that year. He immediately began exploring new opportunities, freed from the constraints of Volkswagen's governance structure.
In late 2022, Diess joined the supervisory board of Infineon Technologies, one of the world's largest semiconductor manufacturers and a critical supplier to the automotive industry. In 2023, he was named chairman of Infineon's supervisory board, leveraging his automotive industry expertise and relationships to guide the chipmaker's strategy in automotive semiconductors, power management, and electromobility components. The role was particularly significant given the global semiconductor shortage that had plagued automakers in 2021-2022, an area where Diess's experience proved valuable.
In January 2024, Diess took on an even more hands-on role as executive chairman of The Mobility House, a Munich-based company specializing in electromobility charging infrastructure and vehicle-to-grid (V2G) technology. The company focuses on bidirectional charging systems that allow electric vehicles to not only draw power from the grid but also supply power back, creating distributed energy storage networks. Diess's mission at The Mobility House was to accelerate global expansion and advance smart charging technologies that could address grid stability challenges as EV adoption scaled.
The two roles—Infineon and The Mobility House—allowed Diess to continue working on the electromobility transition without the political constraints of a large legacy automaker. He remained an active voice on LinkedIn and Twitter, commenting on industry trends, climate policy, and the pace of automotive transformation. His post-VW career suggested that his vision had been sound, even if his execution at Volkswagen had faltered due to cultural and political obstacles.
Controversies
Labor relations and the 30,000 jobs threat
The defining controversy of Diess's VW tenure was his statement that 30,000 German jobs were at risk if Volkswagen didn't improve productivity and competitiveness. While Diess framed this as a warning meant to motivate change, the works council and unions interpreted it as a threat and a negotiating tactic to extract concessions.
The conflict exposed a fundamental tension in German corporate governance. The codetermination system grants labor substantial power to resist restructuring, even when management argues it's economically necessary. Diess believed this system made German automakers uncompetitive against Tesla and Chinese manufacturers, who could move faster and cheaper without union constraints. Labor leaders believed Diess was using competitive pressure as an excuse to gut worker protections that had served Germany well for decades.
The battle became intensely personal between Diess and works council leader Daniela Cavallo, with leaked details of supervisory board meetings portraying a bitter power struggle. Ultimately, labor won decisively—Diess was ousted, and his successor Blume adopted a far more conciliatory approach, committing to preserve German jobs even at the expense of some efficiency gains.
The Cariad software failure
Diess's decision to take personal responsibility for Cariad, Volkswagen's software division, proved a strategic blunder that directly contributed to his downfall. The division was supposed to create a unified software platform for all VW Group brands, reducing redundancy and enabling over-the-air updates, autonomous driving features, and connected services that modern customers expected.
Instead, Cariad became a money pit, consuming billions while delivering buggy, delayed software that frustrated both customers and brand executives. Key vehicle launches at Porsche (the electric Macan), Audi (updated e-tron models), and Bentley (electrification plans) were delayed by years due to Cariad's failures. The division's struggles suggested that Volkswagen lacked the software engineering talent and organizational culture to compete with Tesla, which had built software excellence into its DNA from inception.
Critics argued that Diess's background was in mechanical engineering and manufacturing, not software, and that his overconfidence in an area outside his expertise led to poor decisions about talent, structure, and timelines. The Cariad disaster also highlighted the difficulty traditional automakers face in transitioning from hardware to software companies, a challenge that plagued not just VW but also GM, Ford, and most legacy manufacturers.
The Elon Musk distraction
While Diess's friendship with Elon Musk was genuine and reflected sincere admiration, it became a political liability that his enemies exploited. The works council used Diess's Musk fandom to portray him as starry-eyed about Silicon Valley disruption and dismissive of Volkswagen's engineering heritage and workforce achievements.
The criticism had merit. Diess's public Tesla cheerleading demoralized VW employees who were working hard to execute the electric transformation. It also demonstrated a tone-deafness about organizational psychology—even if Tesla was objectively better at certain things, constantly telling VW employees this fact was more likely to trigger defensiveness than inspire improvement.
After Diess's departure, his successor Oliver Blume notably distanced Volkswagen from Tesla and Musk, ending the collegial relationship and focusing public messaging on VW's own achievements. The contrast underscored how Diess's approach, while strategically logical, had failed politically.
Dieselgate culpability questions
Although Diess joined Volkswagen two months after the Dieselgate scandal erupted and bore no responsibility for the fraud itself, questions emerged about his handling of the aftermath. Some former executives and whistleblowers alleged that Diess and other leaders were more focused on limiting financial liability than on fully investigating the cultural and systemic failures that enabled the fraud.
These allegations never resulted in legal charges against Diess personally, and no evidence emerged of direct wrongdoing. However, the questions contributed to a perception that VW's post-Dieselgate leadership, including Diess, prioritized protecting the company over accountability, a charge that damaged his reputation for integrity.
Business philosophy and leadership style
Herbert Diess's leadership philosophy was characterized by several key themes:
- Data-driven decision making: Diess relied heavily on analytics, benchmarking, and quantitative metrics to drive strategy, sometimes to the exclusion of qualitative factors like organizational culture and employee morale.
- Aggressive transformation over incremental improvement: Diess believed Volkswagen faced an existential crisis and needed radical change, not cautious evolution. This put him fundamentally at odds with VW's consensus culture.
- External benchmarking: Unusually for a German auto executive, Diess looked to external competitors (especially Tesla) as models rather than focusing solely on internal improvement. This was strategically sound but politically toxic.
- Vertical integration ambitions: Like Musk, Diess believed automakers needed to control more of their supply chain, including batteries and software, rather than relying on suppliers—a significant departure from traditional automotive industry structure.
- Cost discipline and efficiency: Diess's BMW background made him acutely focused on productivity metrics and manufacturing efficiency, viewing VW's German operations as bloated and uncompetitive.
- Public communication and transparency: Diess was more willing than typical German executives to engage publicly on social media and in interviews, a style that generated visibility but also created controversy when his statements were leaked or misinterpreted.
Ultimately, Diess's leadership style was better suited to a startup or a company with centralized control than to Volkswagen's consensual, stakeholder-driven governance model. His failure was less about the quality of his strategic vision than his inability to build the political coalition necessary to implement it.
Legacy and impact
Herbert Diess's legacy at Volkswagen is profoundly ambiguous. On one hand, he drove the company's electric transformation at a critical moment, committing resources and strategic focus to electrification when many competitors were still hedging their bets. The ID family of vehicles, while imperfect, proved that Volkswagen could produce competitive electric cars at scale, positioning the company as Europe's leading electric automaker by volume.
On the other hand, Diess's tenure was marked by bitter internal conflicts, high-profile failures (Cariad), and ultimately his forced removal after just four years as CEO. His inability to work within Volkswagen's governance structure meant that much of his strategic vision was implemented poorly or abandoned after his departure.
The broader question Diess's tenure raises is whether traditional automakers can successfully transform themselves in the electric era, or whether their governance structures, labor arrangements, and cultures make them too slow and political to compete with Tesla and Chinese manufacturers. Diess bet on transformation being possible; his ouster suggested that Volkswagen's stakeholders preferred stability over disruption, even if that meant slower progress.
For the automotive industry, Diess stands as a cautionary tale about the limits of visionary leadership in heavily regulated, unionized environments. His post-VW success at Infineon and The Mobility House suggested his talents were genuine but required different organizational contexts to flourish.
Wealth and compensation
Herbert Diess was one of the highest-paid executives in Germany during his Volkswagen tenure. In 2019, he topped the list of DAX CEO compensation with total pay of €9.9 million ($11.3 million), a figure that included salary, bonuses, and long-term incentive awards. His compensation generated controversy given Volkswagen's ongoing Dieselgate costs and the company's profitability challenges.
In 2023, despite having been ousted in mid-2022, Diess earned €11.2 million from Volkswagen, exceeding his successor Oliver Blume's €10.3 million. The disparity reflected severance payments and deferred compensation vesting, though the exact breakdown was not publicly disclosed. German business media criticized the payout as excessive given Diess's forced departure.
Diess's net worth is estimated at approximately $20 million, though exact figures are difficult to verify given German privacy laws and the lack of public disclosure requirements for private wealth. His holdings likely include accumulated compensation from BMW and Volkswagen, deferred stock awards, and investments in various ventures. His roles at Infineon (as supervisory board chairman) and The Mobility House (as executive chairman) provide ongoing income, though likely less than his Volkswagen CEO compensation.
Unlike American tech executives or founder-CEOs, Diess did not accumulate massive wealth through stock appreciation or equity stakes, as his career was spent in large public companies where executive compensation, while generous, is constrained by European norms and shareholder activism around excessive pay.
