The Ford R9CB is a 999 cc, inline‑three turbocharged petrol engine produced between 2019 and 2023. It features direct fuel injection, a single twin-scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 74–92 kW (100–125 PS) with peak torque of 170–200 Nm, enabling responsive urban drivability and efficient highway cruising.
Fitted to models such as the Fiesta, Puma, and EcoSport, the R9CB was engineered for compact efficiency with a focus on low emissions and urban agility. Emissions compliance was achieved through gasoline particulate filtration (GPF), cooled exhaust gas recirculation (EGR), and precise lambda control, allowing full Euro 6d certification from launch.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) under sustained high-load conditions, highlighted in Ford Service Bulletin 04/2021. This issue stems from thermal stress on the pump’s internal components during aggressive driving cycles. From late 2021, Ford introduced a revised HPFP with improved metallurgy and lubrication pathways.
All production years (2019–2023) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8821).
The Ford R9CB is a 999 cc inline‑three turbocharged petrol engineered for subcompact and crossover applications (2019–2023). It combines direct injection with a twin‑scroll turbocharger to deliver strong low-end torque and refined high-rpm operation. Designed to meet Euro 6d from launch, it integrates GPF and advanced EGR for stringent emissions control.

The twin-scroll turbo provides immediate throttle response ideal for city driving but demands high-quality 0W-20 oil meeting Ford WSS-M2C949-A to protect the high-pressure fuel pump and turbo bearings. Extended high-load operation without adequate cooldown can accelerate HPFP wear—Ford recommends avoiding immediate shutdown after aggressive driving. The GPF requires periodic highway driving (>50 km/h for 15+ minutes) to enable passive regeneration; frequent short trips may trigger active regen cycles or warning lights. Post-2021 engines include an upgraded HPFP per SIB 04/2021.
Oil Specs: Requires Ford WSS-M2C949-A (0W-20) specification (Ford Owner’s Manual). Not interchangeable with generic 0W-20 oils.
Emissions: Full Euro 6d compliance across all model years (VCA Type Approval #VCA/EMS/8821).
Power Ratings: Measured under ISO 1585 standards. 92 kW output requires RON 95 fuel minimum (Ford TIS Doc. M87110).

ISO 1585: Road vehicles — Engine test code
The Ford R9CB was used across Ford's B‑Car and CUV platforms with transverse mounting and exclusive to European and Asia-Pacific markets. This engine received platform-specific calibrations—revised ECU maps in the EcoSport for altitude compensation and modified cooling in the Puma for urban duty cycles—and from 2021 the Fiesta received updated engine calibration for WLTP compliance, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Ford TIS M87120). The 7th VIN digit for R9CB-equipped vehicles is typically 'R' or '9'. Visual identification: black plastic cam cover with '1.0 ECOBOOST' embossing; GPF housing integrated into the exhaust manifold. Critical differentiation from earlier 1.0L EcoBoost (Fox): R9CB uses cylinder deactivation (on 125 PS variants), confirmed via OBD2 mode 22 data. Pre-2021 and post-2021 HPFPs are not interchangeable (Ford SIB 04/2021).
The R9CB's primary reliability risk is high-pressure fuel pump (HPFP) degradation under aggressive or frequent high-load use, with elevated incidence in modified or frequently redlined engines. Ford internal field data from 2021 noted a measurable uptick in HPFP replacements before 80,000 km in performance-oriented variants, while UK DVSA records show low emissions-related failures due to robust GPF/EGR design. Extended high-load operation without cooldown increases thermal stress, making post-drive idle cooldown and correct oil specification critical.
Analysis derived from Ford technical bulletins (2019–2023) and UK DVSA failure statistics (2020–2024). Repair procedures should follow manufacturer guidelines.
