In a few weeks I'm going to get a "loaner" 2012 VOLT (early build) to drive for two weeks. I will be driving it exactly the same way T-T-T as my own VOLT which typically gets 10.5kWh on a full charge. The weather (ambient temp conditions) should still be about the same during this period of time. It will be interesting to compare the energy consumptions of Volt A vs. Volt B. Stay tuned . . .
