Focus RS diff for new Ford Fiesta ST

Largely responsible for these numbers is Ford's all-new 1.5-liter EcoBoost three-cylinder engine that delivers 200 metric horsepower (197 bhp) at 6,000 rpm and 290 Nm (214 lb-ft) of torque from 1,600 to 4,000 rpm.

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. Traction will further be aided by the car's adjustable driving modes: Normal, Sport, and Track, which adjust steering feedback, exhaust volume, throttle response, engine mapping, and traction control.

Fortunately, Ford claims it will be "the most responsive, engaging and fun-to-drive Fiesta ST" ever, thanks to newly-announced technologies including an optional mechanical limited-slip differential (LSD), force vectoring springs, and optional Launch Control.

According to the American vehicle giant, the new ST will deliver the "most responsive, engaging and fun-to-drive Fiesta ST experience ever".

Ford has decided on twist-beam rear suspension with "non-uniform, non-interchangeable, directionally-wound springs", which should make the Fiesta easier to turn in sharply.

It claims this new rear suspension system saves around 10kg compared to a Watts linkage arrangement and also delivers improved reactions to turn-in, directional changes and general steering input.

The 2018 Fiesta ST goes on sale this spring in both three- and five-door body styles, and in ST-1, ST-2 and ST-3 equipment levels.

"We went through three times the normal number of suspension iterations to find a set-up that delivered the exciting driving experience demanded of an ST model, but also comfort and refinement for everyday driving".

Leo Roeks, European Ford Performance director, said: "Hot-hatch drivers are expecting big things from this small vehicle".

It works in conjunction with the enhanced Torque Vectoring Control technology which reduces understeer when cornering.

There's also a special graphical overlay in the instrument binnacle, which houses a 6250rpm-redline tacho.

Ford's outgoing Fiesta ST model is a true giant-killer and remains one of the best bang-for-your-buck hot hatches on the market.

Meantime, Ford's bigger, roomier, safer and higher-tech Mk7 Fiesta went on sale in Europe past year with new driver-assist and connectivity technologies, but won't be sold in Australia because it will only be made in Germany for now, making mainstream variants too expensive.
