Congrads on your new 2017 Volt. My wife and I are on our 2nd Volt, the first being a 2014 Volt we purchased new in Oct. 2013, we traded it in July 2016 for our new Volt Premier. Your Volt will probably get mid 40's mpg's just on the gas engine, probably better than your TDI and thats on regular gas instead of Diesel which usually cost more than regular gas as well.
Don't be afraid to use the gas engine once in a while as well, as the 2016-17 Volts gas engine is quite fuel efficient, and at times our Volt gets over 50 mpg just on gas in hold mode.
Electric range in summer should be high 50's to low 60's. Its nice to know with a fully charged Volt its your choice with just a push of a button you can drive on 100% pure electric or elect to use hold mode, and save that fully charged battery when and where you want to use it. Not many cars have the capability to do that, but the Volt does.
