The U.S. Senate passed a bill Thursday night that would require automakers to sell cars that get significantly better mileage by 2020.
If the bill is also passed by the House of Representatives, Corporate Average Fuel Economy (CAFE) standards will be raised from the current 25 miles per gallon to 35 mpg.
Automakers would still be able to sell trucks and sport utility vehicles that get below the 35 mpg mark in 2020, as long as they have other cars in their lineup to bring up their overall fleet average.
Miles-per-gallon goals for each vehicle class, and a timeline to achieve the 2020 goal incrementally starting in 2011, would be set separately by CAFE regulators.
This is the first time since 1975 that the government has sought to raise the standards for new cars and trucks.
The measure would save up to 1 billion gallons of gasoline every day as of 2020, according to Senate Majority Leader Harry Reid.
"For the automakers that still waver on increasing fuel efficiency, I say this: Don't fight this change, embrace it. Embrace this opportunity to build the high-performance, high-efficiency cars and trucks that Americans want to buy and drive--which we so desperately need for the sake of our national security and global warming," Reid said on the Senate floor Friday morning, according to a statement from his office.
The measure is part of the National Energy and Environmental Security Act of 2007, a comprehensive energy bill that also includes incentives for reducing greenhouse gas emissions, developing alternative fuels and implementing energy efficient technology.
A proposal to include $32 billion in clean-energy tax incentives was cut from the original draft of the bill, after some objected that it would cost U.S. oil companies $29 billion more in taxes.
Car industry lobbyists, which included General Motors, Ford and the Chrysler group, strongly opposed the bill, arguing that it would hurt American automakers financially if they had to meet such strict standards so soon.
In a last-minute voice vote last night, the bill passed 65-27. Seven senators did not vote. (Wyoming was missing one senate vote, due to the passing of Craig Thomas on June 4. Republican John Barrasso was appointed by Wyoming's governor on Friday to take over the seat.)
