As the wheelbase is extended by 53 mm (2.1 in), Ford designers managed to position the wheels higher up into the sheet metal, reducing the perception of overall length and mass.

The Vignale trim is given satin aluminium finishes for the roof rails, fascia and rocker inserts, as well as a signature grille mesh.

[6][7] The ST-Line trim level includes dark-finished 17-inch wheels, a sports body kit, large diffuser, functional roof spoiler, lower wing elements, and polished twin tailpipes.

It has 18-inch wheels, leather interior trim, a heads-up display, the ability to park itself in a space, and a Bang & Olufsen sound system.

[13] On the exterior, the Focus ST features a revised grille, unique 18- or 19-inch alloy wheels, larger rear spoiler and twin-exit tailpipes.

[13] Interior changes include Recaro front seats, aluminium gear knob, pedals and scuff plates, and decorative elements with grey stitching.

The package includes launch control, shift light indicator and rev-matching for the manual EcoBoost variant, Track driving mode, electronically adjustable dampers with potholes detection, red-painted brake callipers and ambient interior lightning.

[16] In June 2022, the Focus received an update in Europe which includes the addition of a new electrified powertrain and some minor changes to the equipment list.

With the EcoBoost Hybrid, the standard alternator is replaced with a belt-driven integrated starter-generator (BISG), enabling energy recuperation during braking and coasting to charge a 48-volt lithium-ion battery pack located beneath the front passenger seat.

The new Connected variant comes as standard with a wireless charging pad, a SYNC 3 infotainment system with navigation, adaptive cruise control, front and rear parking sensors and a rearview camera.

Meanwhile, the ST-Line and Active feature dual-zone climate control, auto-dimming rear-view mirror, rain-sensing wipers and Ford's proprietary door-mounted keypad system, marketed as its Securicode.

[17] In April 2018, Ford announced that all passenger vehicles but the Mustang would be discontinued in the North American market, in order to focus on trucks and SUVs.

[20] Ford limited sales of fourth generation Focus in its 4-door saloon form in Estonia, Latvia, Lithuania, Serbia, Montenegro, North Macedonia, Albania, Bulgaria, Romania, Moldova, Turkey, Cyprus as well as many Asian and African countries.

Ford no longer sells the Focus in Russia, Belarus, Kazakhstan, and Israel due to a broader reorganization of their European branch.

[21] In April 2020, Ford confirmed there are no plans for a fourth generation Focus RS model due to pan-European emissions standards and high development costs.

The company said the decision was led by the semiconductor chip shortage and a priority for its higher selling vehicles, such as the Ranger, Everest, Mustang, Escape and Puma.
