... this chart is a conglomeration of all of the gen2 data I could find here on gm-volt, along with my experiences; mpg in mild weather with moderate AC and heat.

for 277 miles I would estimate somewhere between five and six and a half gallons plus a full battery charge depending on driving conditions. Most likely, you're driving interstate speeds of 75-80mph so probably 6.5 gallons @37-38mpg and 35-40 EV miles on the battery. EV range also suffers at 75-80mph; for EV range chart see this-gm-volt-post#7
