Faced with a record-high national gasoline price of $3.07 per gallon, a senior Republican senator said on Tuesday it was time for lawmakers to take another look at imposing stricter mileage standards on mini-vans and other vehicles. Most Republicans and the White House oppose significantly higher mileage requirements because of the potential impact on U.S. automakers and passenger safety. On Tuesday, the U.S. government reported that the average U.S. weekly retail gasoline price rocketed to $3.07 cents per gallon, up nearly 46 cents from last week, because of Katrina's damage to refineries and pipelines. In June, the Senate voted to reject a Democratic amendment to the energy bill to require better mileage for new gas-guzzling sport utility and other vehicles. Illinois Sen. Dick Durbin had proposed that the standards be revised to boost the fuel economy of passenger cars to 40 miles per gallon (mpg) by 2016, and sport utility vehicles to 27.5 mpg. The proposal was defeated.
