The Ford QYBA is a 1,499 cc, inline‑three turbo‑petrol engine produced between 2015 and 2022. It features gasoline direct injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivered 103 kW (140 PS) and 240 Nm of torque, offering responsive urban performance with compact packaging.
Fitted to models such as the Focus (MK4), Puma, and Fiesta (facelifted 2017+), the QYBA was engineered for efficiency — focused drivers se…
All production years (2015–2022) meet Euro 6b standards (VCA UK Type Approval #VCA/EMS/8842).
The Ford QYBA is a 1,499 cc inline‑three turbo‑petrol engineered for compact hatchbacks and crossovers (2015–2022). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver brisk low‑rpm response and urban efficiency. Designed to meet Euro 6b emissions standards, it balances drivability with regulatory compliance.

The Ford QYBA was used across Ford's C2/B2E platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Puma and revised air intake routing in the Focus—and from 2020 the mild-hybrid (MHEV) variant introduced a belt-integrated starter generator (BISG), creating mechanical and electrical interchange limits. All adaptations are documented in OEM technical bulletins.
The QYBA's primary reliability risk is timing belt tensioner pulley wear in early builds, with elevated incidence in high-temperature climates or frequent short-trip driving. Ford internal field data from 2019 indicated a notable failure rate before 100,000 km in pre-TSB engines, while DVSA records show minimal emissions-related recalls. Extended thermal cycling without belt inspection increases pulley degradation, making timely replacement critical.
Analysis derived from Ford technical bulletins (2016–2021) and UK DVSA failure statistics (2018–2023). 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 QYBA offers strong urban performance but early units (2015–2018) had timing belt tensioner concerns. Post-TSB engines (2019+) are significantly more robust. With proper maintenance—95+ RON fuel, correct oil, and timely belt service—it can deliver reliable service beyond 200,000 km.
Top issues include timing belt tensioner pulley wear (pre-2019), high-pressure fuel pump failure, intake valve carbon buildup (due to direct injection), and plastic thermostat housing leaks. All are documented in Ford TSBs and service manuals.
The QYBA powered the 2017–2022 Fiesta, 2018–2022 Focus (MK4), and 2019–2022 Puma (including MHEV variants). It was never used in the EcoSport or Kuga, which adopted different EcoBoost engines.
Yes. Stage 1 ECU remaps safely yield +15–25 kW on stock hardware. Supporting mods (intake, intercooler, exhaust) allow 170–180 PS reliably. However, HPFP and fuel system upgrades are essential beyond stage 1 to avoid lean conditions.
In a Fiesta, expect ~6.8 L/100km (city), ~4.9 L/100km (highway), or ~48 mpg UK combined. Puma MHEV variants achieve ~4.5 L/100km due to regenerative braking and electric assist.
Yes. The QYBA is an interference engine. Timing belt failure—though preventable with scheduled replacement—can cause piston-to-valve contact and catastrophic damage.
Ford specifies SAE 5W-30 oil meeting WSS-M2C946-A standard. This low-SAPS formulation protects the turbo and emissions system. Change every 16,000 km or 12 months, whichever comes first.
