Enhanced fuel economy is attracting strong interest among car buyers, according to a Harris Interactive Inc. study of nearly 15,000 U.S. consumers.

“As (fuel-saving) technologies move from the drawing board into vehicles, they are likely to be supported by solid consumer demand,” says Scott Upham of Harris' Transportation Research Group.

The study says 63% of U.S. adult consumers are likely to purchase a new vehicle with enhanced fuel economy if it's available when they are next in the market.

Respondents also indicated they are willing to spend an additional $1,673 for hybrid vehicles.

“One of the most significant findings is how gasoline prices are affecting consumer's vehicle purchase decisions,” says Upham.

“Rising gas prices have held steady at $2 per gallon over the last 18 months. This is definitely having an impact.”
