The Obama Administration has a targeted mileage standard for passenger cars and trucks. Automakers have until 2025 to raise the fuel economy on their cars and trucks to 54.5 miles per gallon. It is estimated that this new standard will reduce oil consumption by 12 billion oil barrels. That equals out to saving $1.7 trillion in fuel costs for Americans. And with the decrease of fuel use, comes the decrease of greenhouse has emissions.

Because there is the pressure to reduce fuel consumption and greenhouse emissions, automakers are largely creating alternatively fueled cars and trucks. There are electric and plug in hybrids cars, and in order for this technology to be top notch, better engines and more innovative materials are being explored. 

This new rule can create almost 484,000 new jobs. The automobile sector will collectively boost employment and the economy. Automakers are hiring new design teams and will design and build the future of fuel efficiency in cars. This new employment opportunity creates jobs, and once automobiles start becoming successful and efficient, that will boost the economy sales-wise. Consumers will begin spending the excess money they would spend on fuel to a variety of goods and services across the country, which will boost sales in a variety of sectors.
