The Ford T8MB is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2020 and 2025. It features direct fuel injection, a single twin-scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 92 kW (125 PS) and 240 Nm of torque, optimized for urban efficiency and compact packaging.
Fitted to models such as the Fiesta, Focus, and Puma, the T8MB was engineered for responsive drivability and low CO₂ emissions in city environments. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and updated engine calibration, meeting Euro 6d standards across all production years.
One documented concern is high-pressure fuel pump (HPFP) wear under marginal fuel conditions or frequent short trips. This issue, highlighted in Ford Service Bulletin 21M04, stems from lubrication challenges in the Bosch HDP6 pump design under high-pressure cycling. From mid‑2022, Ford implemented a revised HPFP assembly and updated PCM calibration to reduce wear rates.
All production years (2020–2025) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8901).
The Ford T8MB is a 1,499 cc inline‑three turbo‑petrol engineered for B‑Car and C‑Car platforms (2020–2025). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low-end response and urban efficiency. Designed to meet Euro 6d standards, it balances compact design with everyday drivability.

The twin-scroll turbo provides immediate throttle response and strong mid-range torque, ideal for city and highway driving. However, the high-pressure fuel pump is sensitive to fuel quality—only EN 228-compliant 95 RON (or higher) should be used to prevent HPFP wear. The GPF demands occasional highway driving to enable passive regeneration. Vehicles built before 06/2022 should have the HPFP inspected per Ford SIB 21M04 if experiencing hesitation or fuel rail pressure faults.
Oil Specs: Requires Ford WSS-M2C949-A1 (0W-20) specification (Ford SIB 22M01). Not interchangeable with older Ford oil specs.
Emissions: Euro 6d applies to all 2020–2025 T8MB engines (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under SAE J1349 standards. Power output assumes 95 RON fuel (Ford TIS Doc. T20‑9220).

The Ford T8MB was used across Ford's B‑Car and C‑Car platforms with transverse mounting. This engine received platform-specific calibrations—revised cooling in the Puma for tropical climates and unique ECU maps in the Focus—and from 2022 the Fiesta adopted updated engine mounts for NVH refinement, creating minor ECU and harness interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Ford TIS T20‑9208). The 7th VIN digit is 'M' for T8MB-equipped vehicles. All T8MB engines feature a black plastic intake manifold with '1.5 Ecoboost' branding and a gasoline particulate filter (GPF) in the exhaust manifold. Critical differentiation from T7MB: T8MB uses updated Bosch HDP6 pump (Part No. 0281002950) and revised ECU calibration for WLTP Phase 2 compliance. ECU part number suffix must end in 'T8MB' for full compatibility—ECUs from T7MB lack updated emissions logic and cannot be interchanged.
The T8MB's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in urban/short-trip use. Ford internal field data from 2022 indicated a measurable uptick in HPFP-related warranty claims before 80,000 km for pre-2022 units, while UK DVSA records show GPF-related warning lights are common in vehicles with predominantly city driving. Infrequent highway use and substandard fuel quality make HPFP and GPF maintenance critical.
