The Ford XUJB is a 1,499 cc, inline‑three turbo‑petrol engine introduced in 2020. It features direct fuel injection, a single‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 240 Nm of torque, offering responsive mid‑range performance suited for compact SUVs and hatchbacks.
Fitted primarily to the Puma ST and select Fiesta ST — Line X variants, the XUJB was engineered to bridge the gap between efficiency and sporty…

All production years (2020–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8912).
The Ford XUJB is a 1,499 cc inline‑three turbo‑petrol engineered for compact performance hatchbacks and crossovers (2020–present). It combines direct injection with a single‑scroll turbocharger to deliver brisk mid‑range torque and agile throttle response. Designed to meet Euro 6d standards, it balances spirited driving with low emissions and urban efficiency.

The Ford XUJB was used exclusively in Ford's B‑platform performance variants with transverse mounting and no external licensing. This engine received platform-specific calibrations—enhanced cooling in the Puma ST and revised exhaust routing in the Fiesta ST-Line X—and from Q3 2022 the updated camshaft revision, creating minor service part interchange limits. All adaptations are documented in OEM technical bulletins.
The XUJB's primary reliability risk is camshaft-driven HPFP lobe wear in early builds, with elevated incidence in high-mileage or aggressive driving conditions. Ford internal data cited in TSB-22-1156 noted a measurable increase in camshaft warranty claims for 2020–mid-2022 engines, while UK DVSA records show minimal emissions-related failures due to robust GPF control. Extended oil intervals and frequent short trips increase cam and GPF stress, making oil quality and driving pattern critical.
Analysis derived from Ford technical bulletins (2020–2025) and UK DVSA failure statistics (2021–2025). 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 XUJB is generally reliable when maintained properly. Early engines (2020–mid-2022) had camshaft HPFP lobe wear concerns, but revised units from Q3 2022 improved durability. Regular oil changes with correct 0W‑20 spec and occasional highway driving for GPF regeneration are key to longevity.
Most common issues are camshaft-driven HPFP lobe wear (early builds), GPF regeneration challenges from short trips, minor turbo wastegate rattle, and slight oil consumption under high-load use. All are documented in Ford TSBs and generally manageable with proper maintenance.
The XUJB powers the Ford Puma ST (1.5 EcoBoost 150) from 2020 onward and the Fiesta ST-Line X (1.5 EcoBoost 150) from 2021 to 2023. It is exclusive to Ford’s B‑platform performance variants in Europe.
Yes. Stage 1 ECU remaps typically yield +20–30 kW safely, as the stock internals handle moderate torque increases. However, tuning may accelerate camshaft or HPFP wear in early units. Supporting upgrades (intercooler, downpipe) are recommended for higher stages.
Good for a performance engine. In a Puma ST, expect ~6.8 L/100km (city) and ~5.1 L/100km (highway), or ~42 mpg UK combined. Real-world mixed driving typically achieves 38–45 mpg UK with moderate use.
Yes. The XUJB is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally robust with proper oil maintenance.
Ford specifies SAE 0W‑20 synthetic oil meeting WSS-M2C945-A standard. Using incorrect viscosity (e.g., 5W‑30) may impair turbo, HPFP, and camshaft lubrication. Change intervals should not exceed 15,000 km or 12 months.
