Impact of the Energy Crisis on Demand for Plug-in Hybrid Vehicles

Our research is about plug-in hybrid vehicle choice patterns for the Volkswagen Group from 2016 to the present day for urban use. In the theoretical part, we describe the characteristics and operational aspects of hybrid vehicles, and then present the beginnings of the automotive industry in Hungary. In the primary research, a questionnaire survey was carried out for the period before the energy crisis and then for the period of the energy crisis. The sample size was 2516 in both cases. In our research, we provided the choice decision criteria and their set of values. Then, using the DoctuS knowledge-based framework, we determined the most important attributes for the decision and their degree of informativeness using an inductive inference procedure. Subsequently, analysis of variance was carried out for energy use specific data, which were used to draw conclusions and inferences.
