The Mackinac Center for Public Policy has calculated that, so far, the federal and state governments have committted a total of $3 billion to develop the Chevy Volt. Depending on how many Volts are sold, the subsidy per car could be as high as $250,000. For reference, the average Volt owner makes about $170,000 per year. Perhaps they would prefer a new Ferrari 458 Italia instead of a Volt. They only cost $225,000 each.
