Michigan Capitol Confidential: Chevy Volt Costing Taxpayers Up to $250K Per Vehicle: "Each Chevy Volt sold thus far may have as much as $250,000 in state and federal dollars in incentives behind it – a total of $3 billion altogether, according to an analysis by James Hohman, assistant director of fiscal policy at the Mackinac Center for Public Policy." [The analysis allocates the very large R&D subsidies to the few cars sold so far. This seems a bit unfair, as by this logic, the first car would have been enormously expensive. If they never sell another Volt, then this is more fair. It does point out the large public subsidies that have gone into this project though.]
