Abstract:

This study assessed using purchase incentives to promote the retirement of functional, high-emitting vehicles and increase adoption of advanced clean vehicles by low- and moderate-income California households. Additionally, this study examined the vehicle holdings, vehicle purchase decision-making and financing, travel patterns, and barriers to vehicle access by households in the target population. A statewide, representative survey forms the basis of this study. The survey included a vehicle choice experiment of 1,604 low- and moderate-income households. Results show that offering vehicle rebates significantly increases the adoption of conventional hybrid vehicles, plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs), with purchase rebates of $2,500, $5,000, and $9,500 increasing the purchase rates by approximately 20 percent, 40 percent, and 60-80 percent respectively across vehicle types compared to no rebate. In contrast, offering guaranteed loans had a small and uneven effect on the propensity to purchase these vehicles. Results indicate that low- and moderate-income Californians value their vehicles, as they have the same number of vehicles as the statewide average, which is two vehicles per household. Furthermore, these households spent almost $14,000 to acquire their last vehicle, which is over half of their yearly income.
