Automakers have used improved technology to make cars peppier and bigger, instead of improving fuel economy.
"If 2005 model vehicles, with their better technology, had the performance and size of those in 1987, they would use only 80 percent of the gasoline they do today, according to the Environmental Protection Agency. That alone would get the country nearly halfway to the goal President Bush set in his State of the Union address: to cut American oil consumption enough to nearly eliminate the need to import from the Middle East.
But because Americans have not insisted on better fuel economy, 'we can take the technology in the cars and turn the knob toward performance,' said Karl H. Hellman, an automotive development expert who retired from the E.P.A. two years ago.
Improving mileage now would be easy if drivers sacrificed some zip in new cars, he said, 'but in this country, we don't sacrifice for anything.'"
