According to the American vehicle giant, the new ST will deliver the "most responsive, engaging and fun-to-drive Fiesta ST experience ever".
Ford's new Fiesta ST hot-hatch will emit around 125g/km of Carbon dioxide when it is launched: a reduction of 11% compared to the previous generation ST200, according to Ford data.
Powering the new auto is an all-new three-cylinder, 1.5-litre EcoBoost engine producing 197 bhp and 290Nm of torque.

Officially homologated fuel efficiency and Carbon dioxide emission figures will be published closer to the on-sale date in June.
The "Hot-ish Hatch" take on the latest Ford Fiesta - itself revealed at the end of 2016 - the new Fiesta ST was actually revealed more than a year ago, ahead of a public debut at the 2017 Geneva Motor Show, and only now is it about to go on sale officially in the UK.
When dealer stocks are depleted, the Ford Fiesta ST will be little more than a memory in the United States, as its sales will be discontinued alongside those of its bigger Focus RS sibling. The modes are Normal, Sport and Track.More news: Bears to sign Super Bowl hero Trey Burton
Keeping the engine and road in harmony are the torque vectoring technology found on yesterday's Fiesta ST and an optional Quaife mechanical limited-slip differential.
Launch control is also an option, while active exhaust and even cylinder deactivation are added as standard.
Moving on to the new force vectoring springs, these are said to improve the stability, agility, and responsiveness of the Fiesta ST's twist-beam rear suspension.More news: Final Fantasy VII Remake team is hiring "core members"
Among the advantages offered by this unique suspension configuration Ford quotes a sharper turn-in, compatibility with traditional suspension dampers, and a weight saving of 10 kg compared with a Watt's linkage solution typically used to enhance stiffness. The Torque Vectoring Control system, on the other hand, reduces understeer and improves road-holding by braking the inside front wheel during cornering.
Leo Roeks, European Ford Performance director, said: "Hot-hatch drivers are expecting big things from this small vehicle".
The ST will be available from launch in three-door and five-door bodystyles with sporty ST exterior styling and standard 17-inch or optional 18-inch alloy wheels.More news: American Electric Power Company Inc (AEP) Position Boosted by Synovus Financial Corp
