TLDR;
- Four former VW executives were convicted and sentenced in Germany for their roles in the diesel emissions cheating scandal.
- Jens Hadler, who led diesel engine development, received the longest prison term of 4.5 years.
- The scandal caused a dramatic collapse of diesel car sales in Europe and accelerated VW’s shift toward electric vehicles.
- More than 30 other VW employees await trial as investigations into dieselgate continue.
Four former Volkswagen executives were sentenced on Monday for their roles in the infamous diesel emissions scandal that rocked the global auto industry.
The verdict, handed down by the Braunschweig Regional Court in Germany after a grueling three-year trial, marks the first time senior VW managers have been held criminally accountable for the decade-long “dieselgate” affair.
At the heart of the case was the use of “defeat devices”, software installed in millions of VW diesel vehicles designed to cheat emissions tests by reducing pollution levels only during laboratory inspections. In real-world driving conditions, the vehicles emitted toxic nitrogen oxides at levels far exceeding legal limits, deceiving regulators and consumers alike.
Fraud and Long-Term Corporate Deception
Jens Hadler, who led Volkswagen’s diesel engine development from 2007 to 2011, received the harshest punishment, a prison term of four and a half years. Judges described his actions as “particularly serious” fraud, given that his team knowingly orchestrated the emissions manipulation on more than two million cars.
Hanno Jelden, a former top engineer, was sentenced to two years and seven months in prison for aggravated fraud tied to nearly three million affected vehicles. Meanwhile, Heinz-Jakob Neusser, another senior executive, received a suspended sentence of one year and three months, while a lower-ranking manager, identified only as Thorsten D., was given a suspended sentence of one year and ten months.
Although the sentences were somewhat reduced due to the length of the legal process, the court emphasized that these four executives bore significant responsibility in a scandal involving millions of cars across Europe and the US. The presiding judge, Christian Schutz, also made clear that many others at VW were involved, though the convicted men held leadership roles over many years.
Dieselgate’s Lasting Impact.
The fallout from the scandal extends well beyond the courtroom. Once a dominant force in Europe’s diesel vehicle market, diesel cars accounted for over half of new car sales before 2015. Following dieselgate, this share plummeted to just 10%, as consumers and regulators alike grew wary of diesel technology.

Volkswagen itself has since pivoted sharply towards electric vehicles (EVs) and plug-in hybrids. Today, EVs represent about 25% of new car sales in Europe, and Volkswagen has emerged as the continent’s leading EV manufacturer—selling three times more battery-powered cars than Tesla in recent months.
The scandal also precipitated the resignation of VW’s then-CEO Martin Winterkorn in 2015, as well as multi-billion-euro settlements with prosecutors and affected customers worldwide. The company has paid over €33 billion in penalties and is still embroiled in ongoing civil litigation, including a massive €9 billion investor class action in Germany.
More Trials Are Pending
While the United States acted swiftly in prosecuting VW officials, Germany’s judicial response was slower, drawing criticism. The recent convictions are the first major verdicts against VW’s main brand executives, but dozens more employees remain under investigation.
“The defendants are not alone in this wrongdoing,” Judge Schutz noted, reminding the court that many VW employees contributed to the deceit.
Another 31 individuals indicted in connection with dieselgate await trial in Braunschweig, with proceedings expected to continue later this year.
Notably, some executives charged in Germany, including Hadler and Neusser, also face charges in the US, though Germany’s refusal to extradite its citizens has so far shielded them from overseas prosecution.
