Consumer Preferences for Alternative Fuel Vehicles: A Discrete Choice Analysis

Abstract: In this paper we analyze the potential demand for privately used alternative fuel vehicles (AFVs), based on a nationwide survey in Germany among (potential) car buyers. For this purpose, we applied a stated preference discrete choice experiment, using a wide range of vehicle alternatives (gasoline/diesel, natural gas, hybrid, plug-in hybrid, electric, biofuel, hydrogen) and vehicle attributes. By applying both a multinomial logit model and a mixed (error components) logit model, we estimate the attributes’ influence on vehicle choice and calculate consumers’ willingness-to-pay for the improvement of these attributes. Furthermore, in a scenario analysis, we simulate the impact of monetary and non-monetary policy measures on vehicle choice probabilities. We find that the most promising target group for the adoption of all kinds of AFVs is that of younger, well-educated, and environmentally aware car buyers, who, in the case of electric vehicles, also have the possibility to plug-in their car at home, and who have a high share of city trips and thus need a small car. Moreover, we find that, depending on the vehicle alternative, environmental awareness, and budget constraints for the next vehicle purchase, households are willing to pay substantial amounts for the improvement of fuel cost, driving range, charging infrastructure, CO2 emissions, vehicle tax exemptions, and free parking or bus lane access. Furthermore, the scenario results suggest that conventional vehicles will maintain their dominance in the market, whereas electric and hydrogen vehicles will remain unpopular. The market share of the latter is only expected to rise markedly if massive and multiple policy interventions are implemented. Finally, we find evidence that an increase in the fully electric vehicle’s driving range to a level comparable with all other vehicle alternatives has the same impact on its choice probability as would a market-based, multiple measures policy intervention package.

Consumer preferences for alternative fuel vehicles: A discrete choice analysis

Abstract: This paper analyzes the potential demand for privately used alternative fuel vehicles using German stated preference discrete choice data. By applying a mixed logit model, we find that the most sensitive group for the adoption of alternative fuel vehicles embraces younger, well-educated, and environmentally aware car buyers, who have the possibility to plug-in their car at home, and undertake numerous urban trips. Moreover, many households are willing to pay considerable amounts for greater fuel economy and emission reduction, improved driving range and charging infrastructure, as well as for enjoying vehicle tax exemptions and free parking or bus lane access. The scenario results suggest that conventional vehicles will maintain their dominance in the market. Finally, an increase in the battery electric vehicles’ range to a level comparable with all other vehicles has the same impact as a multiple measures policy intervention package.

Willingness-to-pay for alternative fuel vehicle characteristics: a stated choice study for Germany.

Abstract: In the light of European energy efficiency and clean air legislations, as well as an ambitious electric mobility goal of the German government, we examine consumer preferences for alternative fuel vehicles (AFVs), based on a Germany-wide discrete choice experiment among 711 potential car buyers. We estimate consumers’ willingness-to-pay (WTP) and contingent variation (CV) for improvements in vehicle purchase price, fuel cost, driving range, refueling infrastructure, CO2 emissions and governmental monetary and non-monetary incentives, hereby accounting for diminishing marginal returns for some of the attributes and taking taste differences in the population into account by applying a latent class model with 6 distinct consumer segments. Our results indicate that almost 36% of the consumers are open-minded towards at least one AFV option, with 15% being AFV-affine insomuch that they show a high probability of choosing AFVs despite their current shortcomings. Our results suggest that German car buyers’ WTP for improvements of the various vehicle attributes varies considerably across consumer segments and that the vehicle features have to meet some minimum requirements so that AFVs are shortlisted. Furthermore, the CV values show that decision-makers in the administration and industry should focus on the most promising consumer group of ‘AFV aficionados’ and their needs, that some vehicle attribute improvements could increase AFV demand rather cost-effectively, and that consumers would accept surcharges for some vehicle attributes at a level, which could enable their economic provision and operation (e.g. fast-charging infrastructure), while others might need governmental subsidies to substitute the insufficient consumer WTP (e.g. battery capacity).

Abstract: In the light of European energy efficiency and clean air regulations, as well as an ambitious electric mobility goal of the German government, we examine consumer preferences for alternative fuel vehicles (AFVs) based on a Germany-wide discrete choice experiment among 711 potential car buyers. We estimate consumers’ willingness-to-pay and compensating variation (CV) for improvements in vehicle attributes, also taking taste differences in the population into account by applying a latent class model with 6 distinct consumer segments. Our results indicate that about 1/3 of the consumers are oriented towards at least one AFV option, with almost half of them being AFV-affine, showing a high probability of choosing AFVs despite their current shortcomings. Our results suggest that German car buyers’ willingness-to-pay for improvements of the various vehicle attributes varies considerably across consumer groups and that the vehicle features have to meet some minimum requirements for considering AFVs. The CV values show that decision-makers in the administration and industry should focus on the most promising consumer group of ‘AFV aficionados’ and their needs. It also shows that some vehicle attribute improvements could increase the demand for AFVs cost-effectively, and that consumers would accept surcharges for some vehicle attributes at a level which could enable their private provision and economic operation (e.g. fast-charging infrastructure). Improvement of other attributes will need governmental subsidies to compensate for insufficient consumer valuation (e.g. battery capacity).

A review of factors influencing consumer intentions to adopt battery electric vehicles

Abstract: Despite reducing environmental pollution and the excessive consumption of fossil fuels, the number of battery electric vehicles (BEVs) on the road is still low. Why is this so? Why is the mass adoption of BEVs so difficult to realize? One important reason is that the adoption of BEVs is, to a large extent, dependent on the acceptance of private consumers, and their willingness to adopt this mode of transport is insufficient. This study is a systematic overview of peer-reviewed journal articles to identify the reasons for and against consumer intentions to adopt BEVs. A total of 1846 papers were retrieved and after a two-step identification, 40 papers were finally identified and analyzed in detail. The influencing factors were categorized into three main types, namely demographic, situational and psychological, and they were reviewed separately. In addition, the shortcomings and deficiencies in the current studies were also noted.
