Well, we still don't have an exact answer, which is partly due to the fact that GM hasn't yet finished developing the vehicle's complex software systems. In an interview with Fox Car Report Live, vehicle line directory Tony Posawatz shed some light on the topic, saying that the Volt's sustained mileage will be "better than any conventional car, and we're trying to figure out how close, or if it will actually be better than any hybrids."
To put that figure into perspective, we'd imagine that means the Volt would fall somewhere between the 32 mpg rating of the Toyota Yaris and the 50 mpg rating of the Toyota Prius when running under charge-sustaining mode with an otherwise depleted battery pack. Whatever the case, don't expect this hot-button topic to go away any time soon. Click past the break to see the exchange on video.
