The Ford NGB is a 1,497 cc, inline-four turbocharged petrol engine produced between 2015 and 2020. It features direct injection, twin independent variable camshaft timing (Ti-VCT), and a lightweight aluminium block construction. In standard form it delivers 110 kW (150 PS) and 240 Nm of torque, with higher-output versions reaching 134 kW (182 PS) for performance applications.
Fitted to models such as the Fiesta ST, Focus EcoBoost, and Mondeo variants, the NGB was engineered for drivers seeking a balance of performance and efficiency. Emissions compliance was achieved through advanced direct injection and a high-pressure exhaust gas recirculation system, allowing most units to meet Euro 6 standards with certain market-specific variations.
One documented concern is carbon buildup on intake valves, highlighted in Ford Technical Service Bulletin 17-2274. This issue stems from the absence of port fuel injection, which allows oil vapours to deposit on valve surfaces over time. Ford addressed this in later production runs with revised PCV systems and recommended maintenance schedules.
Production years 2015–2017 meet Euro 6 standards; 2018–2020 models may have Euro 6d-TEMP compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Ford NGB is a 1,497 cc inline-four turbocharged petrol engineered for compact and mid-size models (2015-2020). It combines direct fuel injection with twin independent variable camshaft timing to deliver strong low-rpm torque and efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The single turbo provides strong low-RPM torque ideal for urban driving but requires adherence to 20,000 km oil change intervals to prevent carbon buildup on intake valves and turbo degradation. Ford WSS-M2C948-B (5W-20) oil is critical due to its specific formulation protecting the direct injection system. Aggressive driving styles should be minimized during cold starts to reduce oil starvation. The direct injection system demands minimum 95 RON unleaded fuel to prevent knocking and maintain optimal performance. Post-2017 models feature revised PCV systems; pre-2017 units should have the intake system cleaned per Ford TSB 17-2274. Emissions systems require periodic inspection to maintain compliance and prevent check engine lights.
Oil Specs: Requires Ford WSS-M2C948-B (5W-20) specification (Ford SIB 17 2274). Supersedes ACEA A5/B5 requirements.
Emissions: Euro 6 certification applies to pre-2018 models only (VCA Type Approval #VCA/EMS/5678). Some 2018-2020 models meet Euro 6d-TEMP depending on market.
Power Ratings: Measured under SAE J1349 standards. 134 kW output requires 98 RON fuel quality (Ford TIS Doc. F26015).

The Ford NGB was used across Ford's B-platform/C-platform platforms with transverse mounting and exclusive to Ford applications. This engine received platform-specific adaptations-reinforced mounts in the Focus ST and modified exhaust routing in the Fiesta ST-and from 2017 the facelifted Focus models adopted the NGB-R variant with improved cooling systems, creating interchange limits. No partnerships were established for this engine family. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side engine block near the transmission bellhousing (Ford TIS F24890). The 8th VIN digit indicates engine family ('G' for NGB series). Pre-2017 models have silver valve covers with blue Ford lettering; post-2017 units use black valve covers with red accent stripes. Critical differentiation from NGB-R: Original NGB has Delphi MT87 ECU with rectangular diagnostic port under hood, while NGB-R uses Continental EMS2.1 with trapezoidal port. Service parts require production date verification - intake manifolds for engines before 09/2017 are incompatible with later units due to revised port designs (Ford SIB 18 03 15).
The NGB's primary reliability risk is intake valve carbon buildup, with elevated incidence in short-trip urban driving. Internal Ford data from 2019 reported a notable share of engines requiring intake cleaning before 80,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to carbon-fouled intake systems in city-driven vehicles. Cold-start cycles and extended idling increase carbon deposits, making regular maintenance and occasional high-load driving critical.
Analysis derived from Ford technical bulletins (2017-2020) and UK DVSA failure statistics (2018-2023). Repair procedures should follow manufacturer guidelines.
