My winter MPG so far is around 18-19 (heat running full blast for my commute, heated seat all the way up, city stop and go snow traffic with AWD kicking in from time to time). It obviously can't touch the HHR / HHR SS in fuel economy, but I'm flying past everybody SAFELY in the worst possible conditions. As a matter of fact, Milwaukee usually has 33" of snow by this time of year; we're going to hit 80"+ by the end of Sunday. I know I sound like a broken record, but AWD ROCKS! I'm never going back. I would LOVE it if there was an HHR or HHR SS with AWD...
