Despite the ongoing emissions scandal involving Volkswagen and other automakers, diesel-powered vehicles were still on display at the 2017 Frankfurt Auto Show. However, there was a noticeable shift in the messaging and marketing of these vehicles, with a greater emphasis on fuel efficiency and emissions reduction technologies.

Several automakers showcased new diesel models at the show, including Audi, BMW, Mercedes-Benz, and Volkswagen. These vehicles featured advanced emissions control systems and technologies aimed at reducing nitrogen oxide (NOx) emissions, such as selective catalytic reduction (SCR) and urea injection systems.

To counter negative perceptions of diesel vehicles due to the emissions scandal, automakers highlighted the benefits of diesel engines, such as improved fuel economy and lower CO2 emissions compared to gasoline engines. They also emphasized the investments they were making in research and development to further reduce emissions and improve the environmental performance of diesel vehicles.

Additionally, some automakers announced plans to electrify their diesel powertrains in the future, signaling a gradual shift towards alternative fuel technologies. For example, Mercedes-Benz unveiled a concept version of its EQ Power diesel hybrid technology, which combines a diesel engine with an electric motor and battery to reduce emissions and improve fuel efficiency.

Despite the ongoing challenges facing diesel vehicles, automakers at the Frankfurt Auto Show demonstrated their commitment to improving the environmental performance of these vehicles and emphasized their continued role in the automotive industry, albeit with a greater focus on sustainability and emissions reduction.
