A more hardcore and lightweight version of the Mk7 Ford Fiesta (shown above) is in the works, and like its higher performance Focus sibling, it will be called the Ford Fiesta RS. According to Auto Express, the new 7th generation Ford Fiesta will have two high performance versions instead of just the ST, similiar to the line-up planned for its bigger brother, the Ford Focus. The Fiesta will have a “warm” Fiesta ST, as well as an all-out hot hatch Ford Fiesta RS.
The Mk6 Fiesta ST came with a 150 PS 2.0 litre Duratec, so the new Mk7 RS has to top the 150 PS figure. While there are no official details yet, the Mk7 ST is rumoured to come with a new 1.6 litre EcoBoost turbocharged inline-4 engine instead of a large normally aspirated Duratec engine, so it will be very easy to tune up this engine for the RS version. Expect the ST to feature 150 horses or so, and the RS to top out at nearly 200 horsepower.
