For those who haven't been around here that long, and just to show that it can be done, several years back MNL member LEAFfan drove his 2013 24kWh LEAF 188 miles on flat ground before charging, at an average speed between 18-19 mph, averaging 8.8mi./kWh. This was a deliberate record attempt in the Phoenix area, done on a hot day to minimize drag. AFAIA this remains the un-recharged distance record for a 24kWh LEAF.
