The Ford QXBA is a 1,498 cc, inline‑three turbo‑petrol engine introduced in 2022 as part of Ford’s EcoBoost family. It features a DOHC 12‑valve layout, direct fuel injection, and a single twin‑scroll turbocharger. In standard form it produces 110–125 kW (150–170 PS) with torque between 240–270 Nm, offering responsive low‑end pull and efficient urban performance.
Fitted to models such as the Puma, Focus, and Kuga, the QXBA was engineered for compact efficiency without s…
All production years (2022–present) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9352).
The Ford QXBA is a 1,498 cc inline‑three turbo‑petrol engineered for compact and crossover applications (2022–present). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑rpm response and smooth mid‑range pull. Designed to meet Euro 6d from launch, it balances everyday usability with regulatory compliance.

The Ford QXBA was used across Ford's B‑Car and C‑Car platforms with transverse mounting and no external licensing. This engine received platform-specific calibrations—revised cooling in the Kuga and updated mounts in the Focus—and from late 2023 the Puma adopted an updated ECU map for cam follower durability, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The QXBA's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear under sustained high-load or aggressive driving conditions. Ford internal data from 2024 indicated elevated HPFP-related warranty claims in pre-late-2023 builds, while UK DVSA records show minimal emissions-related failures due to robust GPF control. Aggressive driving without cooldown cycles and marginal fuel quality amplify wear, making fuel specification and post-drive idle critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The QXBA is generally robust when maintained properly. Early models (2022–late 2023) had HPFP cam follower concerns, but Ford’s late-2023 update resolved most issues. Using 95+ RON fuel (98 RON recommended), adhering to oil specs (0W-20 WSS-M2C949-A), and allowing post-drive cooldown greatly enhance longevity.
Top issues include HPFP cam follower wear (pre-late 2023), GPF clogging from short trips, turbo actuator calibration drift, and minor valve cover oil seepage. These are documented in Ford TSBs and are manageable with proper maintenance.
The QXBA powers the Puma (2022–present), Focus (2022–present), and Kuga (2022–present) in 1.5L EcoBoost variants. All are transverse-mounted applications in Ford’s global B- and C-platform vehicles, compliant with Euro 6d emissions.
Yes. Stage 1 ECU remaps typically yield +15–25 kW safely due to strong stock internals. However, aggressive tuning without HPFP and cam follower upgrades may accelerate wear. Ford’s factory overboost already delivers 270 Nm temporarily.
In a Puma 1.5L, 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 driving style and GPF regeneration cycles.
Yes. The QXBA is an interference engine. Timing chain failure—though rare due to front-mounted design—could cause piston-to-valve contact. Ford specifies the chain as lifetime, but severe oil neglect may compromise it.
Ford mandates 0W-20 synthetic oil meeting WSS-M2C949-A specification. This low-viscosity oil ensures GPF compatibility and proper chain lubrication. Do not substitute with older 5W-30 or non-approved oils.
