Fuel efficiency standards for both passenger vehicles and light trucks would increase by 4.5 percent per year over the five-year period ending in 2015 – a 25 percent total improvement that exceeds the 3.3 percent baseline proposed by Congress last year – under a new proposal announced April 22 by U.S. Transportation Secretary Mary E. Peters.
"This proposal is historically ambitious, yet achievable," Peters said. "It will help us all breathe a little easier by reducing tailpipe emissions, cutting fuel consumption, and making driving a little more affordable."
For passenger cars, the proposal would increase fuel economy from the current 27.5 miles per gallon to 35.7 miles per gallon by 2015. For light trucks, the proposal calls for increases from 23.5 miles per gallon in 2010 to 28.6 miles per gallon in 2015.
All told, the proposal will save nearly 55 billion gallons of fuel and a reduction in carbon dioxide emissions estimated at 521 million metric tons. The plan will save America's drivers over $100 billion in fuel costs over the lifetime of the vehicles covered by the rule, Peters said.
