The US administration Tuesday proposed a stepped-up schedule for improving automobile fuel efficiency, accelerating plans in a law enacted last year.
Transportation Secretary Mary Peters said the new proposal would increase fuel efficiency for both passenger vehicles and light trucks by 4.5 percent per year over the five-year period ending in 2015.
This would be a 25 percent total improvement that exceeds the 3.3 percent baseline proposed by Congress last year.
"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."
