By the end of the year, Ford Motor Co. is expected to expand its EcoBoost fuel-saving technology to three additional engines.

We’ll know more soon this Tuesday at the SAE World Congress in Detroit from Barb Samardzich, Ford’s vice president of powertrain engineering, who is slated to provide more details about EcoBoost production plans. To reduce fuel consumption and CO2 emissions, the technology combines direct fuel injection, variable cam timing and turbocharging. In a statement, Samardzich said that Ford intends to truly make a difference by focusing on sustainable technology solutions that can be used for millions of cars. She will also be talking about Ford’s plans to offer a start/stop engine feature on as many as 20% of Ford’s global nameplates by 2014. Ford said that the feature is seen to lower fuel consumption and emissions by about 5%, depending on conditions. Ford’s next three EcoBoost engines will be: (1) a 1.6-liter four-cylinder that will be offered in the European version of the C-Max compact minivan; (2) a 2.0-liter four-cylinder for the next-generation Ford Explorer and Edge; and (3) a 3.5-liter V-6 for rear-drive F-150 applications. Information on hp and torque has yet to be released but Ford asserts that the engine has the power and towing capability of a V-8.
