The Ford T8CM is a 1,999 cc, inline‑four turbocharged petrol engine produced between 2021 and 2025. It features dual overhead camshafts (DOHC), 16 valves, and gasoline direct injection (GTDI). In standard form it delivered 184–224 kW (250–305 PS) and 400–450 Nm of torque, engineered for high — performance applications with responsive mid‑range thrust and refined high‑rpm character.
Fitted to models such as the B257 Focus ST Edition, C519 Puma ST, and B563 Kuga ST — Line,…
All production years (2021–2025) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9781).
The Ford T8CM is a 1,999 cc inline‑four turbocharged petrol engine engineered for high-performance compact and crossover models (2021–2025). It combines gasoline direct injection (GTDI) with a twin-scroll turbocharger and dual independent variable cam timing (Ti-VCT) to deliver responsive power delivery and strong torque across a broad rev range. Designed to meet Euro 6d emissions standards, it balances sporty character with environmental compliance.

The Ford T8CM was used across Ford's performance-oriented B257/C519 platforms with transverse mounting and no external licensing. This engine received platform-specific calibrations—revised intercooler routing in the B257 Focus ST Edition and modified exhaust manifold in the C519 Puma ST—and from early 2023 the updated B563 Kuga ST-Line adopted the revised HPFP design, maintaining full hardware interchangeability. All adaptations are documented in OEM technical bulletins.
The T8CM's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear in early builds, with elevated incidence in track-use or aggressive street driving. Ford internal field data from 2024 indicated up to 5% of pre-early-2023 engines required HPFP replacement before 70,000 km, while UK DVSA records show no significant GPF-related MOT failures linked to this engine. Extended oil change intervals and aggressive driving without warm-up accelerate wear, making oil specification and driving habits critical.
Analysis derived from Ford technical bulletins (2022–2025) and UK DVSA failure statistics (2021–2023). 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 T8CM is robust when maintained properly. Early units (2021–early 2023) are prone to HPFP wear under aggressive use, but later revisions resolved this. Regular oil changes with 5W‑20 Ford‑spec oil, quality fuel, and proper warm-up before hard driving ensure longevity beyond 180,000 km.
Top issues include HPFP cam follower wear (early units), GPF clogging from short trips, turbo actuator faults, and intercooler hose detachment. These are documented in Ford TSBs and addressed with updated OEM parts. No major bottom-end failures are commonly reported.
The T8CM 2.0L EcoBoost appears in the Focus ST Edition (2021–2025), Puma ST (2021–2025), and Kuga ST-Line (2021–2025). All are transverse front‑wheel‑drive or AWD performance applications. It was not licensed to other manufacturers.
Yes. Stage 1 ECU remaps typically yield +25–35 kW (+34–47 PS) safely due to robust internals and twin-scroll turbo. Larger gains require upgraded intercooler, fuel system, and GPF management. Tuning should preserve GPF regeneration cycles to avoid legal and reliability issues.
In a 2022 Focus ST Edition, real-world consumption is ~9.5 L/100km (city) and ~6.6 L/100km (highway), or about 31 mpg UK combined. With mixed driving, 34–37 mpg (UK) is achievable. Economy suffers if GPF or HPFP issues restrict performance.
Yes. The T8CM is an interference engine. If the timing chain fails (rare but possible with severe oil neglect), valve-to-piston contact can cause catastrophic damage. However, the chain is generally durable with proper maintenance.
Ford specifies SAE 5W‑20 synthetic oil meeting WSS‑M2C945‑A. Using thicker oils (e.g., 5W‑30) or non‑approved specs can worsen HPFP lubrication and increase GPF ash loading. Change every 15,000 km or annually.
