The Ford SEBA is a 1,999 cc, inline‑four turbocharged petrol engine introduced in 2023 as part of Ford’s EcoBoost family. It features direct fuel injection, a single twin-scroll turbocharger, and dual overhead camshafts (DOHC). In standard tune it produces 177–237 kW (240–320 PS) with torque peaking at 400–450 Nm, delivering strong performance for sporty applications.
Fitted to high-performance derivatives such as the Focus ST and Mustang Mach-E GT Performance (as range extender variant), the SEBA was engineered for responsive throttle response, high-revving character, and track-capable durability. Emissions compliance is achieved through gasoline particulate filtration (GPF), cooled exhaust gas recirculation (EGR), and precise lambda control, meeting Euro 6d standards from launch.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) under sustained high-load conditions, noted in Ford Service Bulletin TSB-25-0442. This stems from thermal stress and marginal fuel lubricity in low-quality petrol. Ford addressed it in early 2025 with revised pump internals and updated PCM calibration.
All production years (2023–present) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9745).
The Ford SEBA is a 1,999 cc inline‑four turbocharged petrol engineered for performance hatchbacks and crossovers (2023–present). It combines direct injection with a twin‑scroll turbocharger to deliver immediate boost response and high specific output. Designed to meet Euro 6d from launch, it balances track-ready performance with stringent particulate and NOx compliance.

The twin-scroll turbo provides immediate boost and high-rev responsiveness ideal for performance driving, but sustained track use or mountain towing can accelerate HPFP wear if fuel quality is substandard. Ford WSS-M2C948-B1 (0W-20) oil is essential for GPF compatibility and turbo bearing longevity. Use only EN 228-compliant 95 RON or higher petrol—98 RON recommended for ST variants. Post-early-2025 engines include updated HPFP internals per TSB-25-0442; earlier units benefit from PCM calibration updates during service visits. GPF regeneration is automatic but requires occasional highway driving to complete passive cycles.
Oil Specs: Requires Ford WSS-M2C948-B1 (0W-20) specification (Ford Owner’s Handbook 2024). Not backward compatible with older Ford oil specs.
Emissions: Euro 6d certification applies to all model years (2023–present) under VCA Type Approval #VCA/EMS/9745.
Power Ratings: Measured under UN ECE R85 standards. 237 kW variant requires 98 RON for optimal performance and knock margin (Ford TIS Doc. P2570).

The Ford SEBA was used across Ford's C2 and GE1 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts and oil pan baffling in the Focus ST for track durability, and unique exhaust manifolding in the Mustang Mach-E GT Performance for range extender packaging—and from early 2025 the Focus ST Mk4.5 adopted a higher-output calibration with unique exhaust tuning, creating ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (Ford TIS P2562). The 7th VIN digit indicates engine family ('S' for SEBA series). All SEBA units feature a black cam cover with 'EcoBoost' branding and a gasoline particulate filter (GPF) integrated into the exhaust manifold. Critical differentiation from earlier QQDC: SEBA uses revised cylinder head with sodium-filled exhaust valves, updated HPFP, and GPF from launch. ECU part numbers must match exact model/year—calibrations are not interchangeable between Focus ST and Mach-E without full reprogramming (Ford SIB TSB-25-0442).
The SEBA's primary reliability risk is high-pressure fuel pump (HPFP) degradation under sustained high-load conditions, with elevated incidence in hot climates or frequent track use. Ford internal data from 2025 indicated a measurable uptick in HPFP warranty claims for pre-2025 builds, while UK DVSA records show GPF-related limp-mode events are rare but linked to chronic urban-only use. Extended idling and poor fuel quality accelerate wear, making fuel specification and driving pattern critical.
