There's no way you can accurately measure, as you're driving the car, and at the same time charging the battery.
The best thing you could do, is replace the battery with a large capacitor (provided the volt's electronics aren't going haywire).

But yeah, you won't be able to accurately measure; unless you add the driving distance of the charged state of the battery.
Eg: You start out with a complete empty battery, until the battery is like 50% charged. Then you turn off the engine, and continue to drive on the remaining juice of the battery.
I think that's about as accurate as you can get.

At 60MPH, the Bolt, Cruze, or Volt, uses about 6HP to maintain speed.
The Cruze does about 50MPG average on that.
The Volt, probably loses some efficiency, but it being in the high 40's of MPG would probably be quite spot on.
