The Ford XUCA is a 1,499 cc, inline‑four turbo‑petrol engine produced between 2018 and 2023. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 118 kW (160 PS) and 250 Nm of torque, with strong low‑rpm response for agile urban driving.
Fitted to models such as the Mk8 Fiesta, Puma, and EcoSport—including the ST‑Line and Titanium trims—the XUCA was engineered for responsive performance a…
All production years 2018–2023 meet Euro 6d-TEMP (RDE Step 1) standards .
The Ford XUCA is a 1,499 cc inline‑four turbo‑petrol engineered for compact hatchbacks and crossovers (2018–2023). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver responsive low‑end torque and smooth high‑rpm power. Designed to meet Euro 6d-TEMP standards, it balances sporty drivability with urban efficiency.

The Ford XUCA was used across Ford's B‑platform derivatives with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Puma for off‑road durability and revised cooling ducts in the EcoSport—and from 2021 the facelifted Fiesta ST‑Line adopted updated engine calibration with HPFP hardware revisions, creating minor interchange limits. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The XUCA is generally robust when maintained properly. Early units (2018–2020) had HPFP concerns, addressed by Ford in 2021. With correct 0W‑20 oil, quality fuel, and timely SIB updates, it can exceed 200,000 km reliably.
Top issues include HPFP wear (pre‑2021), turbo wastegate rattle, carbon buildup on intake valves, and thermostat housing leaks. All are documented in Ford service bulletins and often preventable with proper maintenance.
The XUCA powers the Fiesta Mk8 (1.5 EcoBoost 160 PS), Puma (1.5 EcoBoost 155 PS, including MHEV), and select EcoSport export models (2020–2023). It is exclusive to Ford’s B‑platform transverse applications.
Aftermarket ECU tuning is common on the XUCA 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.
In a Fiesta 1.5 EcoBoost 160 PS, expect ~6.8 L/100km (city) and ~4.9 L/100km (highway), or ~48 mpg UK combined. Real-world mixed driving typically returns 42–50 mpg UK depending on conditions.
Yes. The XUCA is an interference design. Timing chain failure—though rare—can cause piston-to-valve contact and catastrophic damage. Fortunately, the chain is maintenance-free and highly durable under normal use.
Ford specifies SAE 0W‑20 oil meeting WSS-M2C948-B1. This low-viscosity oil is critical for turbo bearing lubrication and fuel economy. Never substitute with 5W‑30 or non-approved synthetics.
