There were rumors of the inline 5 2.5l turbo being in it, but nothing seen yet. Same motor in the volvo. It's in the curretn euro Focus ST. The RS is makign over 350hp I think with different internals and more boost.

More likely a 2.0l ecoboost is goign to make it into it as it would not be economical to add a whole new motor when they could just boost the current.

I would rather a ecoboost in the Fiesta.
