Three Michigan universities have returned or are in the process of returning three electric vehicles produced by Miles Automotive because of limited range. According to reports university personnel were promised a vehicle range of 80 miles per charge but have only been able to realize half that or less, the equivalent of about half a work day. This is approximately the range that is currently estimated by the manufacturer for the vehicle, so it sounds like performance for these vehicles, which the universities were using on a trial basis, was over promised. The range problem is being attributed to the cold Michigan weather’s negative impact on battery performance. Learn more: Autologgreen.com
