With gas prices staying at steadily-high prices, consumers are beginning to shift their preferences as a result. A recent study commissioned by Ford found that a growing number of drivers rank fuel efficiency as the primary deciding factor when it comes to buying a new or used car.

The nationwide research found that the criteria has experienced a significant jump in the last decade. Specifically, for people buying smaller cars like the Ford Fiesta, a vehicle's gas mileage came in as the top consideration for 2011 – a marked jump from the fourth place it occupied in 2001. Fuel efficiency is even one of the most important considerations for people buying SUVs, currently ranking in fifth, up from 16th.

The findings are indicative of the growing number of manufactures who are making a point to focus on offering especially fuel-efficient cars. Ford in particular has been active, even creating an all-electric version of its popular Ford Focus, and the company feels as though the study is validation of its more eco-friendly push over the last few years.

"Drivers want fuel economy choices – not a one-size-fits-all solution – and Ford is leading the way," said Mark Fields, Ford's president of The Americas. "Customers are telling us clean and green vehicles matter because they are good for people's wallets and good for our planet."
