Nearly a decade after the global auto industry was rocked by Volkswagen’s diesel emissions cheating scandal, known as “Dieselgate,” a German court has delivered a landmark verdict. Four former executives have been convicted of fraud, two receiving prison sentences, in what marks the end of a lengthy legal battle — but not the end of accountability.
A Scandal That Shook the Global Auto Industry
In a verdict that closes a pivotal chapter in one of the world’s most notorious corporate frauds, the Braunschweig Regional Court in northern Germany on Monday convicted four former Volkswagen executives of fraud for their roles in the Dieselgate scandal. The convictions come nearly nine years after the Wolfsburg-based automaker admitted to rigging diesel engines to cheat on U.S. emissions tests.
Two of the convicted executives will serve prison sentences — the former head of diesel engine development was sentenced to four and a half years, while the former head of drive electronics received a term of two years and seven months. The other two executives were handed suspended sentences, including a former member of Volkswagen’s development board and a former department head.
The charges stemmed from the manipulation of software embedded in diesel engines, which allowed cars to pass emissions tests under lab conditions while emitting up to 40 times the legal limit during regular driving. This elaborate deception not only triggered global outrage but also cast a long shadow over Germany’s most prestigious auto brand.

Legal Reckoning Years in the Making
The Braunschweig trial, which began in 2021, is one of the most complex legal proceedings in Germany’s recent history. The prosecution accused the executives of knowingly misleading regulators and customers, ultimately contributing to Volkswagen’s misleading claims of environmentally friendly diesel technology.
Prosecutors had called for sentences ranging from two to four years in prison and argued that probation should be granted in only one case. Defense lawyers, meanwhile, pleaded for three acquittals and one warning, citing a lack of concrete evidence of criminal intent and questioning the executives’ knowledge of the illegal practices.
The court ultimately sided with the prosecution in finding that the accused were fully aware of the consequences of installing defeat devices and failed in their duty to prevent fraudulent activity.
While these convictions are significant, they are far from comprehensive. Thousands of lawsuits and class actions remain pending across jurisdictions. Volkswagen itself has paid out over €30 billion ($34 billion) in settlements, fines, and recalls since the scandal erupted in 2015.
Martin Winterkorn: The Missing Link
Conspicuously absent from the courtroom on judgment day was Martin Winterkorn, the former CEO of Volkswagen, once hailed as the titan of German engineering. Winterkorn had been expected to stand trial alongside the four convicted executives but was removed from the case due to persistent health issues.
Now 78, Winterkorn has repeatedly denied knowledge of the software manipulations. Prosecutors, however, maintain that he was aware of the illegal defeat devices as early as May 2014 — over a year before the U.S. Environmental Protection Agency formally uncovered the fraud. His trial has been repeatedly postponed due to medical concerns, and it remains uncertain whether proceedings against him will ever resume.
Winterkorn resigned shortly after the scandal broke but has never accepted personal responsibility for the deception. He has appeared in court both as a witness and a defendant in related civil matters, but has avoided direct legal reckoning for now.
Conclusion: A Milestone, Not the End
The convictions in Braunschweig serve as a milestone in the ongoing pursuit of justice in the Dieselgate affair. They offer a semblance of accountability in a scandal that betrayed consumer trust, tarnished a flagship brand, and exposed deep flaws in global regulatory oversight.
Yet many questions remain unanswered. Chief among them: Will Martin Winterkorn — the man once at the very top — ever face a full trial? And how can the industry ensure that emissions standards, now tightened in many countries, are enforced with integrity?
As electric vehicles rise and the auto industry shifts gears, the specter of Dieselgate will continue to remind the world that green promises must be more than software-deep.
