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, the T8CM was developed under Ford’s performance EcoBoost strategy to deliver engaging dynamics while meeting stringent emissions targets. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and precise fuel metering, allowing full Euro 6d compliance across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) cam follower under sustained high-load conditions, highlighted in Ford Technical Service Bulletin TSB‑24‑0056. This issue stems from marginal lubrication at the cam-follower interface during aggressive driving cycles. From early 2023, Ford introduced a revised HPFP with surface-hardened components and improved oiling passages.
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 T8CM’s twin-scroll turbo and high specific output deliver spirited performance but require strict adherence to 15,000 km oil change intervals using Ford WSS‑M2C945‑A (5W‑20) oil to protect the turbo bearings, HPFP, and timing chain. Extended intervals or aggressive driving without proper warm-up can accelerate HPFP cam follower wear. Only EN 228-compliant ultra-low-sulfur petrol should be used to maintain GPF and injector integrity. Pre-early-2023 engines should be monitored for hard starts or misfires; affected units may require HPFP replacement per TSB‑24‑0056.
Oil Specs: Requires Ford WSS‑M2C945‑A (5W‑20) specification (Ford TSB‑24‑0056). Not interchangeable with ACEA A5/B5 without verification.
Emissions: Euro 6d certification applies to all T8CM production years (VCA Type Approval #VCA/EMS/9781).
Power Ratings: Measured under ISO 1585 standards. Output verified on B257 Focus ST Edition chassis (Ford PT‑2024).

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front face of the cylinder block near the exhaust manifold (Ford TIS FTS‑9920). The 7th and 8th VIN digits indicate engine type ('CM' for T8CM 2.0L). All T8CM units feature black plastic valve covers with '2.0 EcoBoost' embossing. Critical differentiation from T7DB: T8CM uses updated HPFP (CV6Z‑9351‑CC), revised ECU calibration for ST Edition models, and enhanced intercooler plumbing. Pre-early-2023 engines use HPFP part number CV6Z‑9351‑CB; post-early-2023 units use CV6Z‑9351‑CC—verify via casting mark on pump housing per Ford TSB‑24‑0056.
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.
