I've needed to run errands over the long holiday in triple digit temps and yes my battery mileage has dropped from a daily average of 43 miles to 35. Granted when I say triple digit temp's I'm talking about temps in the 105 to 110 and having to park the Volt outside in the sun vs garaged between errands as is usually the case with my life style, has taken a big chuck out of my all electric range.
Understand our average temps this time of year in St Louis is about 94 degrees and we've just had 8 straight days of TRIPLE DIGIT temps so this is most likely worst case for many folks.
Last evenin I went out to the garage to check the garage doors and the Volts TMS was running. The temp inside my garage was 98 degrees. That's how far the heat has permeated into our house and tha was after sunset last night.
