Ford Focus Shows off Three-Cylinder EcoBoost in Frankfurt
Previewing an all-new high-efficiency powerplant that will be used in its future U.S. products, the Blue Oval took the wraps off a Ford Focus configured with a three-cylinder EcoBoost engine at the start of the Frankfurt Motor Show, one of the largest auto shows in the world.
“By offering the Focus with an advanced small-displacement petrol engine Ford is not only making a major statement on how serious we are about engine downsizing—it also shows the strength of our development and engineering capabilities. To produce a 1.0-liter EcoBoost petrol engine with such impressive performance and fuel economy is a clear example of our commitment to be class-leading in fuel economy,” said Graham Hoare, executive director, Powertrain, Ford of Europe.
The 1.0-liter engine leverages Ford’s growing powertrain expertise to deliver the same kind of power found in today’s naturally aspirated 1.6-liter I4 engines—like those in the current U.S. Focus and Ford Fiesta—but with significantly reduced emissions and improved fuel efficiency. In this country, the engine is expected to develop roughly 118 hp and more than 125 lb.-ft. of torque. While fuel economy ratings are not yet available, it’s helpful to remember the latest models of the American Fiesta and Focus are both able to achieve up to 40 mpg highway.
Also notable is that Ford has made significant efforts to deliver a smooth-running, refined experience with the new engine, something that has often been missing in other automakers’ past attempts to introduce three-cylinder engines to the U.S. mainstream. For example, the clean-sheet design of Ford’s newest and smallest Ecoboost engine features:
- the two main engine drive belts are literally immersed in oil for enhanced quietness, efficiency and durability
- unbalanced flywheel and pulley that, combined with optimized engine mounts, improves operation without the need for power-sapping balance shafts
- exhaust manifold cast directly into the engine’s cylinder head, which keeps the air-to-fuel ratio at optimum levels in more driving conditions
- “split cooling” system and cast-iron block to help the engine more quickly warm up to its ideal operating temperatures
- low-friction coatings for engine components
- standard Ecoboost technologies like intelligent variable valve timing, direct injection and turbocharging
