A bipartisan group of more than two dozen lawmakers wants the EPA to change the 30-year-old test that sets fuel economy ratings. Why? Because in real-world driving, they say, no one gets the mileage posted on the window sticker and published in government guides.
If enacted, the proposed bill would require the EPA to make the test do more to reflect the real world. That would mean more high-speed driving, more aggressive accelerating and stopping, more short trips, driving with air conditioning on and varying the outside temperature.
Advocates of change include a coalition of environmental groups and AAA, which has 47 million members.
Automakers like the test the way it is.
Some environmentalists believe more-realistic ratings would put more pressure on automakers to improve fuel economy. Criticism of mileage ratings has escalated since gasoline-electric hybrids reached the market. Some hybrids have promised more than 60 mpg, leaving buyers unhappy when they can't get that result.
