Update: A representative from GM has informed us that "the DoD has yet to announce it's planned procurements for advanced technology vehicles", so apparently our sources for this story were inaccurate. We'll follow this one to see what happens (was this a leak that will only become official later, or was this just something someone made up?).
Get Ready for Some ControversyAll automakers are constantly trying to get big fleet buyers to pick their cars, and all big fleet operators must constantly juggle a variety of criteria to decide which model to buy. This mating dance resulted in the U.S. Department of Defense putting an order for 1,500 Chevrolet Volts. This will no doubt be controversial with the crowd who spent years saying that the Prius would flop, and who are now saying that the Volt will too. The fact is, we don't know how the Pentagon did the math. Chances are, some political considerations were taken into account, but they might have had more to do with reducing the use of oil from unstable corners of the world and, if most of the fleet doesn't drive huge distances, saving taxpayers money on fuel over time (what matters is total operational lifetime costs, not just the upfront cost of the vehicles).
Besides, if the goal is to save taxpayers some money, those 1,500 Volts don't even add up to a single fighter jet, so budget hawks should probably look elsewhere first.
