Ford announced the introduction of its smallest EcoBoost engine yet at the Frankfurt Motor Show: the Grand C-Max. But the automaker is reportedly working on even thriftier two- and three-cylinder engines for use in future small cars.
Ford’s Vice President of Powertrain Engineering Barb Samardzich told Automotive News that two- and three-cylinder engines and other motors with displacements below 1.0-L are possible in the future. The engines would help the company meet the ever-increasing fuel economy and emissions standards across the globe.
“I think you’ll see all of those things roll out,” said Samardzich. “It’s more than experimental.”
Samardzich wouldn’t give a timetable for production of such engines or the markets in which they would appear, but it is likely the engines would first be introduced in Europe and developing markets where small cars dominate.
To help quell the noise and vibration issues inherent in small-displacement, low-cylinder count engines, Ford will use balance shafts. Samardzich said the NVH problems are “manageable.”
For now, the smallest engines Ford will offer in the U.S. are the 2.0-liter naturally aspirated engine in the Focus and, in the near future, the 2.0-liter EcoBoost engine. Ford has not said if the 1.6-liter EcoBoost engine will make its way to the U.S. when the Grand C-Max debuts in late 2011.
