If you think you're hearing a lot lately about Ford's EcoBoost engine, get ready to hear a lot more. The automaker said this week that the Fiesta will be the first vehicle sold in the U.S. offering Ford's smallest EcoBoost engine: a 1-liter, 3-cylinder turbocharged gasoline engine.

According to the Detroit Free Press, the engine will be available on the 2014 Fiesta, enabling it to get more than 40 m.p.g. Bob Fascetti, director of global engine engineering, said it will be the most fuel-efficient non-hybrid on the road.

"It is a real tour de force in terms of engineering," Fascetti said.

Despite it's compact size, the EcoBoost engine packs a powerful punch. How small is it? The 123-horsepower engine is so small that Ford packed a display model in a carry-on suitcase to get it to Los Angeles where it will be shown at the auto show later this month.

Ford offers the 1-liter engine in the Focus compact car in Europe. Officials did not say if it will eventually be offered in the Focus in the U.S. as well.

The Fiesta will add to Ford's 8 vehicles that get 40 m.p.g. which is double the number of vehicles capable of this in 2011.

Ford says it's on track to sell 1.5 million vehicles with EcoBoost by 2013. Globally Ford has sold 520,000 EcoBoost engines and 270,000 in North America.

By year-end, Ford will have 11 vehicles on sale with EcoBoost engines. OK Ford, we're interested... How much money are we talking about?
