Car manufacturers are worried of how they can meet the 35.5 mpg fuel mileage set as the new CAFE standards that will take in effect by 2016 in the United States.
The Obama government has cleared a path to take so the goals will be achieved to meet the deadline. The plan will require carmakers to improve the fuel economy of their 
fleet by as much as 5% every year, just like what is being done in several states and in California. The stricter government requirements on fuel mileage standardize the rule from the east coast to the west coast.
The target for the 2012 to 2015 models was not yet clear for the auto makers until the suggested framework came out. The 5% increase with the 2011 models translates to 27.3 mpg on average according to the EPA and the Transportation Department.
The levels of improvement for the production cars of 2012 to 2016 will be leveled up from 33.6mpg to approximately 38 mpg. Light trucks are expected to have fuel mileage figures jump to 28.33 from 25.0 mpg.
The 2016 models will also need to meet the emission standards that will be in effect. The law dictates that the average carbon dioxide emission should have a combined figure of 250 grams per mile.
Consumers are on a win-win situation, aside from the cleaner air, they can get as much as $3000 savings in fuel spending over the expected years of their vehicles. According to government studies, it will take three years for consumers to recover the higher cost of spending for the new vehicles that will meet the stricter fuel economy and emission standards.
The total economy of the U.S. is also looking at an equivalent savings of taking about 58 million cars off their roads. The air will also be 900 metric tons of emissions cleaner.
