37 MPG Combined For 2014 Ford Fiesta With 1.0-Liter Ecoboost Engine

Four- and five-door five-speed manual-equipped 2014 Ford Fiesta SE manual with the EcoBoost Package are now EPA certified at 32 mpg city, 45 mpg highway and 37 mpg combined.

Ford said this makes the Ford Fiesta 1.0-liter EcoBoost engine America’s most fuel-efficient non-hybrid, gasoline-powered car; with a certified 45 mpg rating on the highway, the Fiesta tops the Honda Fit by 12 mpg and the Toyota Yaris by 8 mpg on the highway.

Per Ford, the fuel economy rating not only establishes the Fiesta 1.0-liter EcoBoost as best-in-class, but it also outperforms some competitors’ diesels and hybrids on the highway driving cycle. Ford cites the 2014 Honda Insight, achieving 44 mpg highway; or the 2014 Volkswagen Golf diesel with a manual transmission delivering 42 mpg highway.

Ford also boasts this makes the Fiesta the only car in its class that produces more than 120 horsepower and achieves 45 mpg on the highway. Plus, while the 1.0-liter EcoBoost engine is officially SAE-certified at 123 horsepower and 125 pound-feet of torque, it features a torque overboost function that allows it to make more than 145 pound-feet for up to 15 seconds.

“With the new Fiesta 1.0-liter EcoBoost we’re pushing into fuel economy numbers only seen on hybrids and diesels,” said Joe Hinrichs, executive vice president and president of the Americas for Ford. “Coupled with the new Fiesta ST, Fiesta covers the performance-efficiency continuum in the subcompact segment better than any other nameplate in the market.”

Fuel economy is often cited as the No. 1 purchase consideration in the subcompact class, according to Ford research.

The 1.0-liter EcoBoost engine to be found in the 2014 Ford Fiesta was named International Engine of the Year in 2012 and 2013.

As the smallest engine in the growing EcoBoost family, it is increasingly the choice of Ford customers in Europe, where it is now available on five models, accounting for 32 percent of Focus sales and 26 percent of Fiesta sales this year. Robust demand for the 1.0-liter in Europe prompted Ford to double production capacity at its Cologne, Germany, plant to more than 1,000 engines a day.

Ford explained EcoBoost technology combines smaller-displacement engines with turbocharging, direct injection, variable valve timing and proprietary Ford software to bring customers both performance and fuel economy.

Per Ford, EcoBoost engines deliver up to 20 percent better fuel economy than larger-displacement gasoline engines.

Ford’s global EcoBoost engine family now includes the 1.0-liter three-cylinder; 1.5-liter, 1.6-liter and 2.0-liter four-cylinder engines; and the 3.5-liter V6 engine.

EcoBoost technology is available in every region Ford serves worldwide, and will be offered on approximately 80 percent of the company’s global nameplates by the end of this year.

Beyond the efficient new EcoBoost powerplant, Fiesta’s aerodynamic design also helps save fuel. Along with cruise control, the Fiesta SE Manual EcoBoost Package package adds a rear spoiler, side air deflectors, underbody shields, lower grille blockers and low-rolling-resistance tires that, per Ford, together, decrease the amount of fuel needed to push the car through the air at speed.
