Right it sort of goes like this:
The EPA says we want cars to get 65mpg by 2030.
The entire auto industry says that doing so will price the average auto beyond the average consumer's price range.
The EPA then says that they are willing the shoulder the costs until economics of scale can lower the cost of future technology.
Since GM was too busy just trying to swim while ripping off its bondholders, and we gave away Chrysler to the Italians, the two largest, functioning auto OEMs who were at the very beginning of a new development cycle where Ford and Nissan. Thus Ford and Nissan received funding first since they were ready to begin a new development cycle. As more auto OEMs come round to new development cycle, they too will receive money.
Properly framed, the auto OEMs are taking money in order to try to hit the EPA goals with cost-effective, new technology that is affordable for the masses. Without the funding, the entire auto industry told the EPA nobody could afford the kinds of vehicles that could meet the EPA standards with available technology.
If you have trouble with this government lending program, vote for people who tree hug less.
