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.

When the C-Class predecessor launched, it was known as the 190 and carried a four-cylinder powerplant underhood. Mercedes is now considering a return to four-pots in the U.S. market as the price of fuel continues to soar. MBZ is reportedly already testing a 1.4-liter carrying a supercharger, which is strange when you consider there's already a 1.8-liter blown four-cylinder on sale in Europe. The C180 Kompressor seems like it'd be the easy way to get fours back into the U.S. lineup, but Mercedes must have some other ideas driving the decision to develop the smaller 1.4.
