There's no doubt that the Ford EcoBoost engine saves money at the pump. However, this engine also enhances power so well that it's popular among sports car enthusiasts and heavy-duty truck drivers alike. Millions of drivers have crossed into EcoBoost territory, and it's easy to see why.

The majority of modern Ford vehicles offer the EcoBoost engine, helping buyers achieve both improved fuel economy and reduced greenhouse emissions without sacrificing power. With its EcoBoost lineup, Ford is giving buyers an affordable alternative to both hybrid and diesel vehicles. The 2015 Mustang can be equipped with a turbocharged 2.3-liter four-cylinder engine that produces a robust 300 horsepower and 280 pound-feet of torque - enough for thrilling acceleration and an athletic ride. The current F-150 pickup truck tows its maximum rating - 12,200 pounds - with the 3.5-liter EcoBoost V6 engine under the hood.

The Ford EcoBoost engine also finds a welcome home in many practical, family-friendly Ford models. The full-size Fusion sedan is offered with a turbocharged 2.0-liter EcoBoost four-cylinder that produces 240 horses and 270 pound-feet of torque. That's more than enough power for swift highway merging and lane passing. As is the norm with the EcoBoost, this engine also gives the Fusion its best EPA ratings, achieving 22 city/32 highway mpg.
