Want better mileage? You can have your say today

Would you like your car to get better gas mileage?

Federal officials will be in Philadelphia today to take testimony on proposed fuel efficiency standards that would require cars to get 54.5 miles a gallon -- a "fleet" average -- by 2025.

Today's average? About 27 mpg. By one estimate, the new standards could save consumers $4,000 in fuel costs over the life of an average vehicle.

At a similar hearing Tuesday in Detroit, home of the American automobile, about 90 people testified -- mostly in favor.

"Writing new regulations that will require cars and trucks to have significantly higher fuel economy by 2025 prompted years of fighting among automakers, environmentalists, regulators and consumer groups. But now that the standards have been proposed, nearly everyone involved in the process is on board with the results," write Nick Bunkley in the New York Times.

"There appears to be no significant opposition amongst responsible persons," said U.S. Rep. John D. Dingell, a Michigan Democrat who had fought earlier attempts to boost fuel economy.

"These standards will cut our oil use by more than we get from Persian Gulf, Venezuela and Russia combined," said Larry Schweiger of the National Wildlife Federation.

Six veterans testified as well, pointing out that our need for imported oil threatens national security -- and American lives.

Today's hearing begins at 10 a.m. at the Crowne Plaza Philadelphia Downtown, 1800 Market Street. It is being held by the U.S. Environmental Protection Agency and the National Highway Transportation Safety Administration.
