The company says the new model owes much to the spirit of the original fast Fiesta, the 1981 XR2.
Due for launch at the end of the year, it features a 150bhp, 2.0-litre Duratec ST engine and performance chassis tuning.
'The new Fiesta ST puts Ford back into the heartland of small-car performance in a great-to-drive package that's accessible for, often younger, driving enthusiasts to own and insure,' said Derrick Kuzak, Ford of Europe's vice president for product development.
'It succeeds by being the ideal all-round hot hatch – safe, and easy to handle, with no surprises. That's a proven recipe for Fiesta performance and executed better than ever.'
