Bottom line, the more "hybrid-y" and "electric" things become, the less relevant MPG numbers become to real world results. Heck, even now I see them as more of an index, since it is all relative to your driving style. These cars are even more sensitive to changes in driving style and distance than conventional cars. Look how Top Gear proved that an M3 following a Prius driving flat out is more fuel efficient.
