A new Harris Poll has found that U.S. customer interest in battery-electric, plug-in hybrid electric, and gasoline-electric vehicles has largely remained unchanged since 2013.

According to the recent study, 48 percent of U.S. car owners (or anticipated owners) said they would consider a traditional hybrid for their next vehicle purchase, identical to findings in a 2013 Harris Poll.

In addition, 29 percent of owners would consider plug-in hybrid electric vehicles (up 2 percentage points from 2013), while the customer consideration level for battery-electric vehicles was 21 percent (also up 2 percentage points).

Polled customers' top concerns related to battery-electric, plug-in hybrid electric, and gasoline-electric vehicles were price (67 percent) and range (64 percent), followed by repair/maintenance costs (58 percent), reliability (53 percent), performance/power (50 percent), and the vehicle types' status as new technology (42 percent), according to the study.

The poll consisted of 2,225 U.S. adults (aged 18 and older) surveyed online from May 20-26, 2015. Click here for full results of this study.
