Whether diesel has a future or not is a question of credibility. The scandal about manipulated exhaust emissions has shown what has been wrong in the automobile industry for years.
On the one hand, there is Volkswagen: This is a company in which people placed incredible trust, and yet it was involved in incredible levels of deception. And on the other hand are automakers like Mercedes, Opel and Renault, which apparently just accepted the fact that their diesel models were a great deal dirtier on the road than on the test rig.
And let’s not forget testing authorities such as Germany’s Federal Motor Transport Authority (KBA) which claims to have known nothing about what was going on over the years.
Any question about the future of diesel is also about increasing people’s level of awareness about all that it entails. The KBA is currently showing an astonishing reluctance to conduct its investigation into the diesel affair openly and transparently. For example, it took a massive public outcry for the KBA to disclose important details about the recall of millions of VW vehicles.
