Preferences for zero-emission vehicle attributes: Comparing early adopters with mainstream consumers in California

Ambitious zero-emission vehicle (ZEV) adoption goals have been proposed to decarbonize the transportation sector, while the current market share pales in comparison. Although the distinct socio-economic characteristics of ZEV early adopters relative to mainstream car buyers are well understood, the two groups' preferences for ZEV attributes are not clear. This knowledge gap hinders the development of effective policies to achieve mass ZEV penetration goals. This paper examines consumers' preferences and willingness to pay for ZEV attributes based on 755 early adopters and 3493 mainstream consumers from the 2019 California vehicle survey data. Results show that early adopters are more sensitive to battery range, acceleration performance, home charging availability, and high occupancy vehicle lane access, while mainstream consumers attach greater importance to cost attributes (e.g., fuel and maintenance costs) and charging time. Moreover, the effects of monetary incentives are found to be significant for both groups, whereas neither early adopters nor mainstream consumers value the availability of public charging stations. The findings of this study inform targeted ZEV policymaking and marketing strategies in different adoption stages.

Automated summary

This study finds that early adopters of zero-emission vehicles (ZEVs) are more sensitive to attributes such as battery range, acceleration performance, home charging availability, and high occupancy vehicle lane access, while mainstream consumers prioritize cost attributes like fuel and maintenance costs and charging time. Additionally, monetary incentives have significant effects on both groups, while the availability of public charging stations is not valued by either early adopters or mainstream consumers.
