We can't think of any reason why this shouldn't happen.
Just a month or so away from the debut of the highly anticipated Focus RS, we're getting word that Ford is planning an even more powerful version of the Fiesta ST. We'll call it the Fiesta RS until told otherwise. What we do know is that Ford Performance has already promised to launch 12 models by 2020, including the GT supercar and next gen Focus RS. Expect additional versions of the Mustang and F-150 as well. A potential Fiesta RS also hasn't been flat-out denied by the company.
Ford Performance manager Tyrone Johnson recently told Autocar that "there's more to come from the current Fiesta." Since the Fiesta ST has turned into a smash hit, the business case for an even hotter version is quite evident. But in order for any Ford model to receive the coveted RS badge, the engineering team must make it capable of outperforming lesser models in the range to a specific standard. Basically if the car can't kick ass enough then Ford won't do it. So can the Fiesta become a proper RS car? "Theoretically, yes," confirmed Johnson.
