The Ford HWDA is a 1,998 cc, inline-four petrol engine produced between 2021 and 2025. Part of the Ford EcoBoost Gen-4 family, it features direct fuel injection, turbocharging, and twin-independent variable cam timing (Ti-VCT). Delivering 184 kW (250 PS) and 373 Nm of torque, it was engineered for high-performance driving dynamics and improved efficiency across Ford’s performance and SUV platforms, particularly under mixed and high-load conditions.
Fitted to models such as the Focus ST, Puma ST, and Kuga ST-Line, the HWDA was designed to deliver aggressive throttle response and strong mid-range power delivery while meeting Euro 6d-Full emissions standards. It utilises a high-pressure Bosch HDEV6 fuel system and a Garrett GT1749V variable-vane turbocharger, with emissions control achieved through a three-way catalytic converter, cooled EGR, and gasoline particulate filter (GPF), ensuring compliance across European markets.
One documented concern is early high-pressure fuel pump (HPFP) wear under frequent high-load operation. This issue, highlighted in Ford Service Action 22S07, can lead to fuel pressure instability and misfires if not addressed. From 2023, revised HPFP internals and updated engine management calibration were introduced to improve durability.
Production years 2021–2025 meet Euro 6d-Full standards (VCA UK Type Approval #VCA/EMS/6791).
The Ford HWDA is a 1,998 cc inline-four turbocharged petrol engine engineered for performance applications (2021–2025). It combines direct fuel injection with twin-independent variable cam timing (Ti-VCT) to deliver strong low-end torque and linear power delivery. Designed to meet Euro 6d-Full emissions standards, it balances performance with regulated efficiency.

The turbocharged HWDA delivers strong low-end torque ideal for spirited driving but requires strict adherence to 15,000 km oil change intervals to prevent timing chain wear and turbo bearing degradation. Ford WSS-M2C947-A (5W-30) oil is critical due to its low-SAPS formulation supporting GPF longevity and chain lubrication. Extended idling and short trips increase carbon buildup on intake valves, necessitating periodic cleaning. The Bosch HDEV6 fuel pump demands high-octane petrol (98 RON minimum) to prevent knock and injector coking. Post-2023 models feature revised HPFP internals; pre-2023 units should be inspected per Ford SIB 22S07. GPF regeneration cycles must not be interrupted to maintain emissions compliance.
Oil Specs: Requires Ford WSS-M2C947-A (5W-30) specification (Ford SIB 22S07). Supersedes ACEA C5 requirements.
Emissions: Euro 6d-Full certification applies to all HWDA production models (VCA Type Approval #VCA/EMS/6791).
Power Ratings: Measured under SAE J1349 standards. Full output requires 98 RON fuel (Ford TIS Doc. F21016).

The Ford HWDA was used across Ford's C2/CD535 platforms with transverse mounting and remained exclusive to Ford. This engine received platform-specific adaptations-shorter intake manifolds in the Focus ST and revised cooling paths in the Kuga-and from 2023 the facelifted Focus Mk4.5 adopted revised fuel components, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the timing cover (Ford TIS F20891). The 8th VIN digit indicates engine type ('F' for 2.0L EcoBoost). Pre-2023 models have silver valve covers with black plastic timing covers; post-2023 units use black valve covers. Critical differentiation from later units: Original HWDA uses Bosch HDEV6 injectors with square electrical connectors, while post-2023 variants use trapezoidal connectors. Service parts require production date verification - high-pressure fuel pumps for engines before 06/2023 are incompatible with later units due to internal redesign (Ford SIB 22S07).
The HWDA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in high-performance or track use. Internal Ford quality reports from 2024 indicated a notable share of pre-2023 engines requiring HPFP replacement before 100,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to GPF saturation in city-driven vehicles. Frequent high-load cycles and short trips increase component stress, making fuel quality and driving pattern critical.
