The U.S. Transportation Department imposed new fuel-economy standards on trucks, minivans and some SUVs, a move it said would cut consumers' gasoline bills, at a time when gas prices are at record highs. The National Highway Traffic Safety Administration said new calculation methods -- representing the biggest change to the fuel-efficiency regime in decades -- would encourage auto makers to build heavier vehicles, improving highway safety. But the new standards don't apply to cars or the biggest SUVs, such as the Hummer. And environmentalists said they were too lax to significantly cut gasoline costs or reduce America's dependence on foreign oil.

Despite what we think of CAFE standards, this is welcome news.
