As Ford prepares to launch its 1.0-liter turbo EcoBoost petrol engine for the Ford Focus range next month in the UK, Autocar is reporting a high performance version outputting 177bhp (132kW / 180 PS) is under consideration.

In speaking with Focus director, Gunnar Herrmann, Autocar reports the small displacement three-cylinder engine would incorporate twin sequential turbocharging to boost power output 54bhp (40kW / 55PS) from its current 123bhp (92kW / 125PS) which is already impressive in itself.

Such a power/displacement figure for a forced induction engine would be unprecedented in a mainstream high volume vehicle and would place it near the top of the record lists. Currently the Mitsubishi Lancer Evolution FQ-400 is the highest rated forced induction engine with a power/displacement figure of 203bhp (151.3 kW / 206 PS) per liter.

Ford has reportedly built a prototype which is currently configured with an electric supercharger playing the role of the smaller turbo which then sequentially spools boost over to the larger second turbo taken from 1.6-liter Ecoboost engine.

The high-potency 1.0-liter unit could see first application in the Focus as a precussor variant to the Focus ST.

Additionally, by 2015 Herrmann confirmed all normally aspirated 1.6-liter four-cylinder engines will be replaced by the the 1.0-liter Ecoboost globally.

Herrmann said, "We know there might be some resistance from customers asked to go from a 1.6 to a 1.0, but only until they drive it."
