The Ford T7DC is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2022 and 2024. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it delivers 118–140 kW (160–190 PS) with peak torque of 240–270 Nm, enabling brisk acceleration and responsive low‑end thrust.
Fitted to models such as the Puma ST, Fiesta ST, and Focus ST‑Line, the T7DC was engineered for agile performance and everyday usability.…
All T7DC production years (2022–2024) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9023).
The Ford T7DC is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance hatchbacks (2022–2024). It combines direct injection with a twin‑scroll turbocharger to deliver responsive torque and sporty acceleration. Designed to meet Euro 6d emissions standards, it balances performance with regulatory compliance.

The Ford T7DC was used across Ford's B‑Car and C‑Car platforms with transverse mounting. This engine received platform-specific adaptations—reinforced mounts in the Fiesta ST and enhanced cooling in the Puma ST—and from 2022 the Focus ST-Line adopted a revised intake manifold with acoustic tuning, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The T7DC represents the latest evolution of Ford’s 1.5L three-cylinder EcoBoost, with the lowest documented HPFP failure rate among all variants. Ford internal quality reports (2024) show negligible HPFP-related warranty claims under 120,000 km, while UK DVSA data confirms excellent emissions compliance due to advanced GPF control logic. However, cylinder deactivation solenoid sensitivity and turbo wastegate rattle remain documented concerns under specific operating conditions.
Analysis derived from Ford technical bulletins (2022–2024) and UK DVSA failure statistics (2022–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The T7DC is the most refined and reliable iteration of Ford’s 1.5L three-cylinder EcoBoost, featuring the latest HPFP, ECU, and GPF calibrations. With proper maintenance—especially using 95+ RON fuel and correct 0W‑20 oil—it demonstrates excellent long-term durability. Cylinder deactivation and emissions systems function reliably with regular highway driving.
Issues are rare but include potential HPFP wear under extreme conditions, cylinder deactivation solenoid faults from oil degradation, GPF regeneration failures due to short-trip driving, and occasional turbo wastegate rattle. All are documented in Ford service bulletins and are largely preventable with correct maintenance.
The T7DC powers the Fiesta ST (2022–2023), Puma ST (2022–2024), and Focus ST-Line 1.5L (2022–2024). It is exclusive to Ford’s transverse B- and C-platform performance variants in European markets and is not used in North American or commercial vehicles.
Yes. Stage 1 ECU remaps safely yield +20–30 kW by optimizing boost, timing, and CoD logic. The stock internals handle up to ~220 PS reliably. However, HPFP and fuel system upgrades are recommended beyond stage 1 to maintain rail pressure stability and prevent lean conditions.
In a Fiesta ST, expect ~6.8 L/100km (city) and ~4.8 L/100km (highway), or ~42 mpg UK combined. The Puma ST sees slightly higher consumption due to weight and optional AWD. Real-world mixed driving typically yields 41–47 mpg (UK) depending on driving style and conditions.
Yes. The T7DC is an interference design. Timing chain failure (though extremely rare due to robust front-mounted chain) could cause piston-to-valve contact and severe internal damage. The chain is maintenance-free under normal operating conditions.
Ford specifies 0W‑20 synthetic oil meeting WSS‑M2C948‑B1 standard. This low-viscosity oil is critical for cylinder deactivation function, turbo protection, and chain lubrication. Never substitute with 5W‑30 or non-approved oils, as this may trigger CoD faults or accelerated wear.
