I drive a 2012 Volt and I get at least 50 miles during the warmer months. I rarely use climate control even in the winter, when my range drops to the low 40s. Just for reference, I live in the DC area.
In spring, summer and fall a full charge gets me 56-58 miles on my 2014 Volt. I have some challenging elevations here in PA and use them to my advantage. Rather than burn through a big chunk of EV range, I use Hold going up hills, then regen like crazy in Normal going down. While this burns some gas, I find that I use my EV charge most efficiently in this manner and get better range. My daily drive exceeds my range (70 miles each way), but I have a full charge before I begin each trip, so I have it worked out that when I pull into the garage at home, my charge is fully depleted.
An accurate answer to your question however would not really allow for comparisons since heat/AC are only two of many factors which determine your range. Things like tire inflation, elevation changes, speeds driven, etc. are all major factors in determining range And will vary greatly between cars.
