The Ford UBGA is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2020 and 2025. It features direct fuel injection, a single twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 240 Nm of torque, with strong mid — range responsiveness ideal for compact SUVs and hatchbacks.
Fitted to models such as the Puma ST, Fiesta ST, and Focus ST — Line, the UBGA was engineered to balance sporty performance wit…
Production years 2020–2025 meet Euro 6d standards .
The Ford UBGA is a 1,499 cc inline‑three turbocharged petrol engineered for subcompact and compact performance models (2020–2025). It combines direct injection with a twin-scroll turbocharger to deliver responsive mid-range torque and agile urban performance. Designed to meet Euro 6d emissions, it balances sporty drivability with regulatory compliance.

The Ford UBGA was used across Ford's B6/C2 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations-reinforced mounts in the Puma ST and revised intake routing in the Focus-and from mid-2022 the Fiesta ST facelift adopted updated HPFP hardware, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The UBGA is generally robust when maintained properly. Early units (2020–2022) had HPFP sensitivity to fuel quality, but mid-2022 revisions improved durability. Regular oil changes with Ford-specified 0W-20 and occasional highway driving for GPF regeneration are key to longevity.
The main issues are high-pressure fuel pump wear, GPF regeneration faults from short-trip driving, turbo actuator sticking, and minor cam cover oil leaks. These are documented in Ford service bulletins, particularly SIB 21M05 for HPFP concerns.
The UBGA powers the 1.5L EcoBoost 150 variants of the Fiesta ST (2020–2025), Puma ST (2020–2025), and Focus ST-Line (2021–2025). All meet Euro 6d emissions standards and feature GPF and twin-scroll turbo technology.
Aftermarket ECU tuning is common on the UBGA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Good for a performance engine. In a Fiesta ST 1.5 EcoBoost 150, expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or about 40 mpg UK combined. Real-world mixed driving typically returns 38–44 mpg (UK) with spirited use.
Yes. The UBGA is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. Fortunately, the chain is robust and designed for life-of-engine use under proper maintenance.
Ford specifies SAE 0W-20 oil meeting WSS-M2C945-B1 standard. This low-viscosity oil ensures proper GPF compatibility and turbo lubrication. Never substitute with non-approved oils, as they may harm emissions systems or reduce HPFP life.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
