Diesel is losing popularity in Europe for several reasons, and this trend has been ongoing for several years. Some of the key factors contributing to the decline in diesel’s popularity in Europe include:

1. Environmental Concerns: Diesel engines produce more harmful nitrogen oxides (NOx) and particulate matter compared to gasoline engines. As concerns about air quality and environmental issues have grown, many European cities have imposed stricter emissions standards and regulations. In response to these concerns, governments have imposed higher taxes and stricter emissions regulations on diesel vehicles, making them less attractive to consumers.
2. Emissions Scandals: The “Dieselgate” scandal involving Volkswagen in 2015 revealed widespread cheating on emissions tests by some manufacturers. This eroded trust in the automotive industry and further tarnished diesel’s reputation.
3. Market Shift Towards Electric Vehicles (EVs): Many European countries and cities are pushing for the adoption of electric vehicles to combat pollution and reduce greenhouse gas emissions. Incentives, rebates, and infrastructure development have made EVs more attractive, and consumers are increasingly choosing them over diesel-powered vehicles.
4. Fuel Taxes: Diesel fuel is often subject to higher taxes than gasoline in many European countries. This makes diesel vehicles less cost-effective for consumers who are price-sensitive.
5. City Access Restrictions: Many European cities have introduced low-emission zones or restrictions on older, more polluting vehicles. Diesel vehicles, especially older ones, often fall into the category of vehicles restricted or banned from city centers.
6. Improvements in Gasoline Engines: Gasoline engines have become more fuel-efficient and have caught up to diesel in terms of fuel economy, reducing one of the advantages traditionally associated with diesel vehicles.
7. Technology Advancements: Hybrid and plug-in hybrid technology has become more prevalent and offers a transition between traditional internal combustion engines and fully electric vehicles. These technologies provide consumers with options beyond diesel.
8. Resale Value Concerns: Diesel vehicles often have lower resale values due to concerns about future regulatory changes and the perception that they are less desirable.
9. Public Perception: Diesel has developed a negative public image, with many consumers associating it with pollution and environmental harm.
10. Changing Government Policies: Governments in Europe have been shifting their policies to promote cleaner and more sustainable transportation, often at the expense of diesel.

It’s important to note that while diesel has lost popularity, it hasn’t disappeared entirely. Diesel engines still have their applications in some commercial vehicles, such as trucks and certain types of machinery, where their fuel efficiency and torque make them more suitable. However, in the passenger car market, the shift away from diesel is clear, with consumers and governments favoring cleaner and more sustainable transportation options.
