In May 2009 President Obama announced domestic car and light truck fuel efficiency standards of 35 mpg by 2016. Europe is expected to reach fuel efficiency of 60 mpg by 2020. This would still leave Europe considerably ahead of the U.S. in fuel efficiency for automobiles, but the gap would be much smaller. For the last several decades the U.S. has fallen sadly behind Europe and Japan in fuel efficiency. The perception of poor fuel efficiency hurt the automakers badly during periods of high fuel prices and when buyers were facing difficult economic choices. The automakers are beginning to grasp this fact. Mark Reuss, president of General Motors, commented that- "it's very challenging, but its upto us engineers to provide high value to the customer and support the environment." This is an issue that has serious national and global implications as it affects the future prices and demand for oil, emissions, and future economic growth. It would also bring the U.S. in line with Europe and Japan when it comes to fuel efficiency of automobiles. ...
