In light of the current pain at the pumps, fuel economy is on all of our minds these days no matter what kind of car you drive. That being the case, it might not be surprising to you that the car we're buying are getting more fuel efficient. Don't believe us? The National Highway Traffic Safety Administration has just revealed that the U.S. auto industry set a new record in overall fuel efficiency during the first half of the 2008 model year by averaging 26.8 mpg through March. That's up from an average of 26.6 mpg through the entire 2007 model year.
