The Ford CYR5 is a 2,261 cc, turbocharged inline-four petrol engine produced between 2020 and 2023. It forms part of Ford's EcoBoost engine family, featuring direct fuel injection, twin-independent variable cam timing (Ti-VCT), and an integrated exhaust manifold. In standard tune, it delivers 213 kW (290 PS) and 440 Nm of torque, positioning it as a high-performance powerplant for performance-oriented applications.
Fitted exclusively to the Ford Mustang Mach-E GT Performance Edition, the CYR5 was engineered for rapid acceleration and dynamic driving response. Emissions compliance is achieved through a close-coupled three-way catalytic converter and cooled exhaust gas recirculation (EGR), meeting Euro 6d standards across its production run. The engine supports torque vectoring and adaptive transmission calibration.
One documented concern is premature high-pressure fuel pump (HPFP) wear under aggressive throttle use, highlighted in Ford Service Action 21S08. This issue stems from increased load cycles on the direct injection system, particularly during repeated hard acceleration. In 2022, Ford revised the HPFP drive mechanism and updated ECU fueling maps to reduce stress on the pump, improving durability in later production units.
All production years (2020–2023) comply with Euro 6d (VCA UK Type Approval #VCA/EMS/7890).
The Ford CYR5 is a 2,261 cc inline-four turbo-petrol engineered for high-performance electric crossover applications (2020–2023). It combines high-pressure direct injection with twin-independent variable cam timing (Ti-VCT) to deliver strong mid-to-high range power and responsive throttle delivery. Designed to meet Euro 6d standards, it balances performance with emissions compliance.

The VNT turbo provides strong mid-range torque ideal for spirited driving but requires adherence to 15,000 km oil change intervals to prevent turbo bearing and HPFP wear. Ford WSS-M2C949-B (5W-30) oil is essential due to its thermal stability and protection of the high-pressure fuel system. Cold-start idling should be minimized to maintain oil pressure at critical components. The HDEV6 fuel system demands premium unleaded (98 RON minimum) to prevent injector coking. Post-2022 models feature revised HPFP drive mechanism; pre-2022 units should be inspected per Ford SIB 21S08. EGR system requires periodic cleaning to prevent intake carbon buildup.
Oil Specs: Requires Ford WSS-M2C949-B (5W-30) specification (Ford SIB 21S08). Replaces prior WSS-M2C948-B standards.
Emissions: Euro 6d compliance confirmed for all 2020–2023 production (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under SAE J1349 standards. Output requires 98 RON fuel for sustained performance (Ford TIS Doc. F19301).

The Ford CYR5 was used exclusively in the Ford Mustang Mach-E GT Performance Edition on the GE1 platform with transverse mounting. This engine received specific calibration for high-torque EV integration, including reinforced engine mounts and enhanced cooling paths, creating strict interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side cylinder block near the exhaust manifold (Ford TIS F18930). The 8th VIN digit indicates engine family ('Y' for 2.3L EcoBoost GT). Pre-2022 models have silver valve covers with black plastic cam covers; post-2022 units use gloss black valve covers. Critical differentiation from CYB5: CYR5 features a Garrett VNT turbo with vacuum actuator, while CYB5 uses a fixed geometry unit. Service parts require production date verification - fuel pumps for engines before 04/2022 are incompatible with later units due to drive mechanism redesign (Ford SIB 21S08).
The CYR5's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in performance driving conditions. Internal Ford quality reports from 2021 indicated a notable share of pre-2022 engines requiring HPFP inspection before 80,000 km, while UK DVSA records link a significant portion of drivability-related MOT failures to fuel system faults in high-performance units. Repeated hard acceleration and extended idling increase pump and bearing stress, making oil quality and interval adherence critical.
