Still an improvement over G1. If I fuel shortly after getting "LOW", I can put 7.6 gallons into the tank. Which means there's easily over a gallon and a half and 60 miles left. But the "LOW" bothers me, as though it were thirsty, and stop and put more in. Probably doesn't matter in the long run, but...Mine shows less than 30 miles on the fuel gauge if I let it go long enough. I think it was at ~15 miles that it switched to "LOW". If you completely "run out" of fuel (the car keeps a reserve in the tank that you can't use), it will switch to "Engine Not Available" reduced power mode and you can drive several miles in order to reach a gas station, but once those several miles are up, the car will shut down until you charge it or put more fuel in it.
