Hotter Fiesta St-plus possible, but no RS
FORD HAS RULED out an RS version of the new Fiesta. Speaking to Autocar at the Geneva motor show, the Fiesta ST’S chief programme engineer, Matthias Tonn, said of an RS version: “There was always room in the range, but it isn’t being developed.”
A Fiesta RS was frequently rumoured throughout the previous generation to sit above the ST model, but it never materialised. Tonn was emphatic that the same will be true for the new Fiesta, too.
Tonn said a model similar to the previous Fiesta ST200 is possible in this generation of Fiesta towards the end of its lifecycle, but it is not in the plan yet. Indeed, the Fiesta ST itself, which made its world debut in Geneva, is still one year away from production, according to Tonn, and development work on the car is ongoing.
Ford will also maintain its close relationship with tuning specialists Mountune, but Mountune has yet to be involved in developing its own version of the new Fiesta ST.
Tonn said the new 197bhp 1.5-litre Ecoboost threecylinder petrol engine made the latest Fiesta ST “so much more responsive and more agile” than the outgoing Fiesta ST.
“It’s a very agile engine and has great responsiveness, new calibration, a new way to ignite the fuel. The engine is more direct and lively,” he said. “We have spent a lot of time on the suspension and chassis and found a new way to set it up.”
When development of the new Fiesta ST began, the benchmark was the previousgeneration ST, but that target moved after the creation of the Fiesta ST200.
Further work has gone into ensuring the car makes the right kind of sound and, to that end, it gets the active exhaust from the Mustang that opens its valves at low revs.
The Fiesta ST will also offer a choice of three driving modes, including a Track mode that’s still in development.
New-gen Fiesta ST won’t be joined by a hardcore RS version
