35 mpg by 2020, 75 mpg by 2030

Fuel cell cars only way forward?

While automakers are already complaining about the technological feasibility of 35 mpg by 2020, things could get far worse. In order to meet greenhouse gas emission reduction requirements currently being proposed, automakers would have to achieve 75 mpg by 2030 according to a top EPA official.

"There are a lot of strategies you need to consider -- both engines and fuels," Margo Oge, director of the Environmental Protection Agency's Office of Transportation and Air Quality recently said in an interview. Automakers "need to be thinking of those investments for the long term basis," beyond the energy bill, Oge said.

Sure automakers will need to use long term vision, which is scary, but how realistic is it to expect automakers to achieve such a massive increase in fuel economy when many members of Congress are still trying to figure out how to make gas cheaper for Americans?
