U.S. buyers may shun SUVs due to gas prices, survey finds.

More than a third of U.S. consumers are considering swapping their SUVs and big cars for more fuel-efficient vehicles because of high gasoline prices, according to a survey released on Wednesday. A poll by Consumer Reports magazine showed that 37 percent of those surveyed said they may replace their current vehicles with more fuel-efficient models. Fifty percent of that group said they were considering buying hybrid models that run on a combination of electricity and gasoline.
