Real world urban driving with hills, traffic,
stop & go, the whole
enchilada. Farthest drive to date was just
over 65 miles and that
brought by average cell voltage to 3.17 V.
Still have some juice left.

Also have done a couple 65 mile highway trips.
The car has no
trouble cruising for over an hour at highway
speeds. Motor and
controller temp never climbed above 45C.
Watt Hours/Mile250 Wh/Mile
Based on my typical Seattle winter driving. In
city with some
freeway and plenty of hills. Also full-time
headlights, some wipers,
and some heat. This should be my worst case
