How Will Volkswagen Diesel Fix Affect MPG?

The scandal surrounding Volkswagen's diesel emissions, commonly referred to as "Dieselgate," caused shockwaves across the industry and led to significant repercussions for the German automaker. As part of the fallout, Volkswagen was required to implement fixes for their affected diesel vehicles, aiming to reduce nitrogen oxide (NOx) emissions and bring them within legal limits. However, the effectiveness of these fixes in terms of fuel economy and overall environmental impact has been a topic of debate. Recently, a test conducted on a Volkswagen diesel vehicle revealed some interesting findings. While the NOx emissions were significantly reduced after the fix, the test car's fuel economy saw a decline, resulting in increased carbon dioxide (CO2) emissions. This demonstrates that the fix had an unintended consequence on the vehicle's MPG, raising concerns about the true effectiveness and environmental benefits of the VW diesel fix.

What Models Are Affected by Dieselgate?

The Dieselgate scandal, which shook the automotive industry in 2015, had a significant impact on several vehicle models. The models affected by this scandal were primarily the 2.0 liter and 3.0-liter diesel vehicles produced by Volkswagen, Audi, and Porsche.

In the 2.0-liter category, the affected vehicle models included the Jetta, Jetta Sportwagen, and Beetle. These models spanned multiple model years, ranging from 2009 to 20It was discovered that these vehicles were equipped with defeat devices, which manipulated emissions tests to meet regulatory standards artificially.

Moving on to the 3.0-liter vehicle models, the scandal also implicated Volkswagen Touareg, Porsche Cayenne, and Audi A6 Quattro. These models were manufactured between the years 2009 and 20Similar to the smaller displacement engines, these vehicles were found to have installed defeat devices, allowing them to emit significantly higher levels of pollutants during real-world driving while appearing compliant during testing.

As a result of Dieselgate, these vehicle models faced significant repercussions. The scandal led to massive recalls, numerous lawsuits, and hefty fines for the manufacturers involved. Additionally, the reputation of the affected brands suffered, as consumer trust in their environmental claims was shattered.

Volkswagen Touareg Hybrid: In Addition to the Diesel Models, Certain Hybrid Vehicles Were Also Implicated in the Scandal. The Volkswagen Touareg Hybrid, an SUV With a Combination of Gasoline and Electric Power, Was Found to Have Manipulated Emissions Tests.

The Volkswagen Touareg Hybrid, a specific type of SUV that’s both gasoline and electric power, was discovered to have been involved in manipulating emissions tests. This finding was part of the larger scandal surrounding Volkswagen and their diesel models.


The VW dieselgate fix test results provide significant insights into the impact of the fix on both emissions and fuel economy. The reduction in NOx emissions by almost half is undoubtedly a positive outcome, highlighting the effectiveness of the fix in addressing the initial environmental concerns. However, the decrease in fuel economy and subsequent increase in CO2 emissions raise questions about the overall environmental impact of the fix. Balancing emissions reduction with fuel efficiency remains a crucial consideration for future automotive advancements.
