I'm curious to know if GM has perhaps opened the window on the battery a little on the 2018 like they did the past Volt models. The current 16-17 Volt seem to get about 14 KWH out of the battery with a full charge, our last trip with our 2016 Volt was 14.2 KWH used. It would be nice to see what the 2018 Volt gets out of a full charge. It would be a piece of cake for GM to open the battery to 14.5 KWH of usable electricity per full charge if they choose to....
