Congratulations on your new Volt! I’ve been driving my 2012 Volt for over six years and am still loving it!
Just keep in mind that the fuel tank holds units of fuel, not units of distance. How far you can drive on each unit is up to you. As time passes, the computer will gather data about your driving habits, and those range estimates you see on the driver’s display will start to better reflect how far you and your driving habits may enable you to go on a full charge. 53 ev miles per charge is a window sticker rating, not a guaranteed promise, but many people meet or exceed it.
Also, think of regenerative braking as an alternative to friction braking in an electric car... any battery recharging (regen) you get from slowing down or driving downhill is a bonus, not the goal of braking.
And if you are using 120 volt charging at home and your wiring is sufficient to charge at 12 amps (8 amps is the default setting), read the manual’s section on Location Based charging to find out how you can set the home charging settings to that level...
