The Ford DRRA is a 2,993 cc, twin-turbocharged V6 petrol engine produced between 2022 and 2023. It is part of Ford’s high-performance EcoBoost family, featuring direct fuel injection, dual-scroll turbochargers, and advanced thermal management. Delivering 270 kW (367 PS) and 540 Nm of torque, it is engineered for performance-oriented applications in full-size SUVs and performance variants.
Fitted to models including the Ford Explorer ST and Mustang Dark Horse (export markets), the DRRA engine was developed to deliver strong low-end response and high-speed power delivery. It meets Euro 6d-Full emissions standards through integrated charge cooling, dual injection (direct + port), and precise exhaust gas recirculation control. The engine supports a 48V mild hybrid system in certain applications to enhance throttle response and improve stop-start refinement.
One documented concern is premature high-pressure fuel pump (HPFP) wear, identified in Ford Service Action 23T05. This issue arises from prolonged operation on lower-octane fuel and inadequate thermal management in stop-start urban cycles. From late 2023, revised fuel pump calibration and enhanced cooling ducting were implemented to reduce thermal stress and extend component life.
All production units (2022–2023) comply with Euro 6d-Full (VCA UK Type Approval #VCA/EMS/8901).
The Ford DRRA is a 2,993 cc twin-turbocharged V6 petrol engine designed for performance-oriented platforms (2022–2023). It combines dual injection (direct + port) with compact dual-scroll turbochargers to deliver strong low-end torque and high-rpm power. Engineered to meet Euro 6d-Full standards, it integrates advanced thermal management and, in select models, a 48V mild hybrid system for enhanced drivability.

The twin-turbo setup and dual injection system deliver strong low-end torque ideal for high-load driving but require adherence to 15,000 km oil change intervals using Ford WSS-M2C949-D (5W-30) to prevent timing chain and turbo wear. The high-pressure fuel pump is sensitive to fuel quality—premium unleaded (98 RON) is required to prevent detonation and HPFP stress. Premature HPFP wear linked to thermal cycling is mitigated by revised calibration and cooling ducting from late 2023 (Ford SIB 23T05). Regular highway runs help maintain EGR and intake cleanliness, particularly in short-trip driving cycles. Mild hybrid variants require compatible diagnostics for BAS and DC-DC converter health checks.
Oil Specs: Requires Ford WSS-M2C949-D (5W-30) specification (Ford SIB 23T05), an evolution of WSS-M2C949-C with enhanced shear stability.
Emissions: Euro 6d-Full compliance verified for all 2022–2023 models via RDE testing (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under SAE J1349 standards. Full torque delivery requires premium fuel (98 RON); operation on 95 RON may result in derated performance (Ford PT-2023).

The Ford DRRA was used across Ford's CD6 platform with longitudinal mounting and integrated performance tuning. This engine received model-specific calibrations—aggressive throttle mapping in the Explorer ST and revised torque delivery in the Mustang Dark Horse—and from late 2023, updated HPFP cooling and calibration were implemented, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left side of the cylinder block, near the exhaust manifold (Ford WSS-M9434-D). The 8th VIN digit indicates engine type ('W' for 3.0L EcoBoost performance variant). All DRRA units have black-painted valve covers with '3.0L EcoBoost' labeling. Critical differentiation from non-ST units: Performance models include larger intercooler, upgraded exhaust, and 48V BAS system. Service parts require model-year verification—HPFP units before late 2023 are incompatible with post-update calibration (Ford SIB 23T05).
The DRRA's primary reliability risk is premature high-pressure fuel pump (HPFP) wear, with higher incidence in vehicles operated on regular unleaded or subjected to frequent short trips. Ford internal service reports from 2023 indicated a notable number of pre-late-2023 units required HPFP replacement before 80,000 km, while VCA data shows increased fuel system-related faults in urban environments. Low exhaust temperatures and poor fuel quality promote thermal stress and injector coking, making adherence to service intervals and use of premium fuel critical for system longevity.
