Regenerative braking, mountain mode would be your excellent use of the second propulsion system. And then there's opportunistic charging and perhaps charging at work. Plugshare is a very good guide. I have home charging but more than half of my charging is from free charging stations that I found using Plugshare.If you don't have access to home charging, such as those living in apartments and condos, I'm not sure a Volt makes a ton of sense either. Yes you could use it but why pay for a second propulsion system you can't use?
