The Ford E5SB is a 2,499 cc, inline-five turbocharged petrol engine produced between 2020 and 2025. It forms part of the EcoBoost Gen-4 family, featuring direct fuel injection, twin-scroll turbocharging, and integrated exhaust manifold. In standard tune it delivers 235 kW (320 PS) with 450 Nm of torque, offering strong mid-range performance ideal for high-performance SUVs and performance-oriented applications.
Fitted to models such as the Explorer ST, Edge ST, and Ranger Raptor, the E5SB was engineered for drivers seeking maximum performance and dynamic capability. Its driving character emphasizes rapid throttle response and sustained turbo boost, particularly in the 2,500–5,000 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 21M05, is primarily associated with extended service intervals and use of low-quality fuel. Later production units (post-2023) incorporated a revised HPFP cam follower design to improve durability.
Production years 2020–2025 meet Euro 6d-Full standards (VCA UK Type Approval #VCA/EMS/8890).
The Ford E5SB is a 2,499 cc inline-five turbocharged petrol engine engineered for high-performance passenger vehicles (2020–2025). 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 towing and spirited driving but requires strict adherence to 15,000 km oil change intervals using Ford WSS-M2C947-B2 (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-2023 models feature revised HPFP cam follower design; pre-2023 units should be inspected per Ford SIB 21M05. Close-coupled catalytic converter longevity depends on fuel quality and thermal management.
Oil Specs: Requires Ford WSS-M2C947-B2 (5W-30) specification (Ford SIB 21M05). Supersedes ACEA C3 requirements.
Emissions: Euro 6d-Full certification applies to all models (2020–2025) (VCA Type Approval #VCA/EMS/8890).
Power Ratings: Measured under SAE J1349 standards. 235 kW output requires 95 RON fuel (Ford TIS Doc. F26020).

The Ford E5SB was used across Ford's U6/T6 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-tuned intake manifolds in the Explorer ST and revised cooling routing in the Ranger Raptor-and from 2023 the facelifted Edge 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 F25890). The 8th VIN digit indicates engine type ('5' for 2.5L EcoBoost). Pre-2023 models have silver valve covers with black plastic cam covers; post-2023 units use black valve covers. Critical differentiation from 2.0L EcoBoost: E5SB has five-cylinder layout, larger turbo housing, and Bosch HDEV6 fuel system. Service parts require production date verification - high-pressure fuel pumps for engines before 06/2023 are incompatible with later units due to cam follower revision (Ford SIB 21M05).
The E5SB'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 2024 indicated a significant number of pre-2023 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.
