“…For example, acceleration rate, engine power, top speed, and horse power were used as an indicator of the driving performance of a vehicle in several previous studies (Gonzalez et al, 2015, 2017; Hampf & Krüger, 2014; Jahromi et al, 2013; Lim, 2016; Voltes‐Dorta et al, 2013). However, as the loading capacities for people and for luggage are also important features for consumers when purchasing a vehicle, seating capacity, volume, and boot space were also considered as outputs (Gonzalez et al, 2015, 2017; Jahromi et al, 2013; Li et al, 2021; Voltes‐Dorta et al, 2013). Furthermore, Gonzalez et al (2015, 2017) used the passenger protection score in the EuroNcap crash tests as an output, as there has been increasing emphasis on the importance of safety equipment in recent years.…”

The Japanese government will adopt the CAFE standard after 2020. By using a "modified" slack-based measure (SBM) model, this study analyzed the technical efficiency of 113 gasoline vehicle models (GVs) and 54 hybrid vehicle models (HVs) sold by Japanese manufacturers in 2016. We also estimated attainable fuel efficiency of specific vehicle models that can be further improved referring to the nearest point on the best practice frontier. The improved CAFE values and standards of the nine automobile manufacturers were calculated. The technology gap from the vehicle technology frontier was more noticeable among gasoline vehicles than among hybrids. Moreover, most automobile manufacturers can achieve the CAFE standard through an effective achievement strategy based on best practice technologies, whereas the others will not achieve the CAFE standard even given a rapid technology innovation beyond the best practice frontiers for GVs and HVs.
