The supplemental power would come from another turbocharger in a production guise, but for testing purposes comes from a supercharger feeding a turbo taken from Ford's 1.6-liter, four-cylinder Ecoboost. A hi-po option would be slated some kind of "performance version of the Focus positioned some distance below the forthcoming 247bhp Focus ST."
Or, if Ford could really get that output to work for production the engine could be an option for the Fiesta ST. Shown off last year, the hotted-up Fiesta was paired with a 180-hp, 177-lb-ft version of the 1.6-liter Ecoboost. Granted, this is all hypothetical, but even with the loss of a noticeable chunk of torque the idea might have its merits.
