Not Toyota, not Ford. In fact not even a large auto maker has broken the world record for the longest distance traveled on a single charge in an electric car. Japan Electric Vehicle Club, a team of EV enthusiast modded a Daihatsu Mira with over 8300 Sanyo batteries and achieved 623.76 miles on one charge. The previous record was set in November of 2009, when they drove 345 miles.
Of course, the condition were, shall we say very controlled. They achieved the feat on a training school track and drove 25mph for 27.5 hours.
