UC Davis study finds discontinuance rate of 21% for California PHEV adopters, 19% for BEV adopters

Green Car Congress

A new study by Scott Hardman and Gil Tal at the University of California, Davis has found that discontinuance occurs at a rate of 21% for California plug-in hybrid adopters and 19% for California battery electric vehicle adopters. For respondents that discontinued PHEV ownership 19% are unlikely to purchase one, 12.4%

Conventional ICEs (internal combustion engines) and HEVs (hybrid electric vehicles) are compared to PHEVs (plug-in hybrids), BEVs (battery-electric vehicles), and FCVs (fuel cell vehicles). Vehicle emissions, then, are underestimated by a similar fraction for BEVs, and by 11–25% for the PHEV pathways. Source: McCarthy et al.
