Vehicle Description

🚗 Overview
The ST‑Line X is the top trim in the ST‑Line family, blending sporty styling with premium comfort. It features the latest mild‑hybrid version of Ford's 1.0 L EcoBoost engine and a seven-speed dual-clutch automatic (Powershift) gearbox

Engine & Performance
Utilises the 1.0 litre three-cylinder EcoBoost 123 PS (or higher 153/155 PS) mild‑hybrid petrol engine. The integrated 48 V starter‑generator boosts low‑end torque and improves fuel economy
.

Typical outputs: ~153 bhp and ~190 Nm torque for the 155 PS version—0–62 mph in ~8.7 s; top speed ~124 mph

The automatic transmission is smooth but can feel slightly sluggish in response; sporty feel is better in the manual gearbox version

Exterior & Design
Sport‑styled ST‑Line X exterior with body kit, 18″ alloy wheels, and subtle sporty cues
Facelifted in 2024 with sleeker front grille, updated headlights, and refreshed bumpers for a modern look

.

Interior & Technology
Redesigned cockpit with improved ergonomics: driver‑facing dashboard, larger 12–12.8″ SYNC 4 touchscreen, wireless Apple CarPlay/Android Auto, B&O 10‑speaker sound system, and optional wireless phone charging (standard on ST‑Line X)
Physical climate controls removed — climate functions moved into a lower touchscreen area, which may be less intuitive while driving

.

Sports‑bolstered seats with red stitching, premium surfaces, and higher-quality finishes than lower trims, though some plastic touches still feel cheap
.

Driving Experience
ST‑Line X features retuned sports suspension; stiffer and broader shocks help better handling over the standard Puma suspension. Ride can feel firm, especially over 18″ alloy rims

Steering and chassis balance feel sharp and responsive. Despite a higher ride height than a Fiesta, handling remains engaging with good composure at speed


The automatic gearbox is smooth but deliberate; enthusiasts might prefer the manual option for more direct engagement

Practicality & Ownership
Five‑door hatchback layout with decent boot space, including the unique MegaBox under-floor storage (common to Puma range)

Reliability: the EcoBoost petrol engine historically used a lubrication‑sensitive timing belt (wet belt) design. Most 2024 mild-hybrid EcoBoost engines now use a timing chain, eliminating the old “wet belt” issue—still, use of correct oil grades and regular oil‑filter/strainer cleaning is recommended to avoid damage

Owners on forums caution:

“It’s still a belt if it’s the 1.0 Fox engine. An updated belt and tensioner is supposed to be released …”
“Many ecoboost engines after 2020 were changed to chain driven.”
