ETROIT -- Ford Motor Co. is replacing its highest volume EcoBoost engine after just four model years.
The 2.0-liter four-cylinder -- offered in more than a dozen Ford and Lincoln vehicles globally -- begins easing out of production early next year with the launch of the redesigned 2015 Ford Edge.
The revamped Edge gets an all-new 2.0-liter EcoBoost four-cylinder as its base engine. The new engine is a total redesign, said Scott Makowski, Ford's chief engineer for large four-cylinder engines. It features a new, lighter aluminum block, redesigned cylinder head, twin-scroll BorgWarner turbocharger, revised fuel injectors and a variable oil pump.
Rapid advances in engine technology led to the demise of the original 2.0-liter EcoBoost, Makow-ski said. It's rare for an engine to be replaced after such a short run. Most engines are offered for about 10 years with periodic upgrades.
Ford left the bore spacing the same on the new engine so it can be built on the current production line, Makowski said.
The 2.0-liter EcoBoost in today's Edge has not sold well, accounting for roughly 10 percent of Edge sales.
Ford spokesman Mark Schirmer said the new EcoBoost engine will be offered with all-wheel drive and a towing package, two options unavailable with the current 2.0-liter engine.
"We think that will drive significantly higher take rates," he said, noting that the new 2.0-liter will also be the standard engine.
At a Ford event last week, Makowski said the new engine will offer more power and have a broader torque curve than the current 2.0-liter's 240 hp and 270 pounds-feet of torque. The 2014 Edge 2.0-liter is EPA rated at 21 mpg city/30 mpg highway.
Two other engines will be available in the 2015 Edge: Ford's nonturbo 3.5-liter V-6, and a new 2.7-liter EcoBoost V-6, available only in the high-performance Edge Sport model.
Ford plans to offer diesel engines in export versions.
