Yesterday we just completed a trip of 68.4 miles and were into the second to the last bar of charge. The GOM showed 22 miles left (which is a joke) so I figure we probably could have gone 80 miles before being in trouble. Our LEAF is a 2011 with over 22,000 miles on it. A 2013 with the extra little added range should make it possible however, if you are going to be driving 65 mph with some hills, make sure you have the dealership show you how the GPS system works and where you can get a charge. You can put in your destination (i.e. home) and then let the system show you the nearby charging stations along your route. I've found that some are Blink units that require a subscription and a card to activate them. The best bet for a free charge is at participating Nissan dealers. I've used a couple of them with very good results.
In our case we were using surface streets all the way and were showing as high as 6.0 miles per kWh and finished the trip in the high 5's. I think that's a joke as well because the LEAF supposedly limits full charge and full discharge of the battery. Thus, if we are allowed to use somewhere around 21 kWh out of 24, then we should have been able to go well over 100 miles which is dreaming. The point is for a new owner that these gauges are not absolute but need to be used as a relative indicator. I use the number of bars left (I wish they had a kWh left display) and compare them to the actual mileage I have driven. Then I can forecast more closely knowing what the remainder of my trip is (e.g. uphill, downhill, speed, etc). Thus, although we kept using the GPS for charging stations, my calculations showed we would make it home without a charge and we did.
