The Ford D6BA is a 1,998 cc, inline-four turbocharged petrol engine produced between 2018 and 2023. It belongs to the EcoBoost Gen-3 family, featuring direct fuel injection, twin-scroll turbocharging, and integrated exhaust manifold. In standard tune it delivers 147 kW (200 PS) with 320 Nm of torque, offering strong mid-range performance ideal for dynamic driving and towing applications.
Fitted to models such as the Focus ST, Puma ST, and Fiesta ST, the D6BA was engineered for drivers seeking a balance of spirited performance and daily usability. Its driving character emphasizes responsive throttle delivery and linear power build-up, particularly in the 2,000–4,500 rpm range. Emissions compliance was achieved through a close-coupled three-way catalytic converter and dual lambda sensor control, allowing it to meet Euro 6d-Full standards across its production run.
One documented concern is premature wear of the high-pressure fuel pump (HPFP), which can lead to fuel pressure instability and misfires. This issue, highlighted in Ford Service Action 19M07, is primarily associated with extended service intervals and use of low-quality fuel. Later production units (post-2021) incorporated a revised HPFP cam follower design to improve durability.
Production years 2018–2023 meet Euro 6d-Full standards (VCA UK Type Approval #VCA/EMS/7891).
The Ford D6BA is a 1,998 cc inline-four turbocharged petrol engine engineered for performance-oriented passenger vehicles (2018–2023). It combines direct injection with a twin-scroll turbocharger and integrated exhaust manifold to deliver responsive acceleration and robust torque. Designed to meet Euro 6d-Full emissions standards, it balances sporty performance with modern efficiency and emissions control.

The twin-scroll turbo provides strong mid-range torque ideal for overtaking and spirited driving but requires strict adherence to 15,000 km oil change intervals using Ford WSS-M2C947-B1 (5W-30) specification oil to prevent high-pressure fuel pump wear. The direct injection system is prone to intake valve coking over time, necessitating periodic walnut blasting or chemical cleaning. Turbo response is sharp, but prolonged high-load operation without adequate cooldown may reduce turbo lifespan. Cold-start idling should be minimized to reduce thermal stress on turbo and exhaust manifold. Post-2021 models feature revised HPFP cam follower design; pre-2021 units should be inspected per Ford SIB 19M07. Close-coupled catalytic converter longevity depends on fuel quality and thermal management.
Oil Specs: Requires Ford WSS-M2C947-B1 (5W-30) specification (Ford SIB 19M07). Supersedes ACEA C3 requirements.
Emissions: Euro 6d-Full certification applies to all models (2018–2023) (VCA Type Approval #VCA/EMS/7891).
Power Ratings: Measured under SAE J1349 standards. 147 kW output requires 95 RON fuel (Ford TIS Doc. F21030).

The Ford D6BA was used across Ford's C2/B2 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-tuned intake manifolds in the Focus ST and revised cooling routing in the Puma ST-and from 2021 the facelifted Fiesta adopted updated engine management software, 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 starter motor (Ford TIS F20900). The 8th VIN digit indicates engine type ('2' for 2.0L EcoBoost). Pre-2021 models have silver valve covers with black plastic cam covers; post-2021 units use black valve covers. Critical differentiation from 1.5L EcoBoost: D6BA has larger turbo housing, Bosch HDEV6 fuel system, and integrated exhaust manifold. Service parts require production date verification - high-pressure fuel pumps for engines before 09/2021 are incompatible with later units due to cam follower revision (Ford SIB 19M07).
The D6BA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in short-trip urban use. Internal Ford quality reports from 2022 indicated a significant number of pre-2021 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased catalytic converter failures in vehicles with poor maintenance. Frequent cold starts and extended oil intervals increase wear, making oil quality and service adherence critical.
