Generation 1 Chevy Volt (2011-2015)
Current Situation:
I currently own a 2007 Nissan Altima Hybrid and I have gotten a lot of miles on it (135,000 and climbing) and my battery capacity is at 70% on the original battery. But I still get around 43mpg in city and when going on the highway without to much wind I get around 38mpg...
