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.

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CYR5 delivers high performance and responsive throttle delivery, but early models (2020–2021) had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2022) improved drive mechanism design and ECU calibration, enhancing durability. Regular servicing and using correct oil (5W-30 Ford WSS-M2C949-B) significantly improve long-term reliability.
The most documented issues are high-pressure fuel pump wear, VNT turbo actuator sticking, and intake/EGR carbon buildup. Additional concerns include oil leaks from aged gaskets and occasional ECU calibration faults. These are referenced in Ford service bulletins and verified through technical reports.
The CYR5 2.3L EcoBoost is used exclusively in the Mustang Mach-E GT Performance Edition. It was introduced in 2020 and continued through 2023 with revisions. This application-specific engine is not used in any other Ford model line.
Yes. The CYR5 is popular for tuning. ECU remaps typically yield +40–60 kW safely on stage 1, as the stock internals handle increased torque. Supporting modifications (intercooler, exhaust) allow higher gains. Tuning is common on Mach-E GT models, but should be paired with maintenance diligence.
In a Mustang Mach-E GT Performance Edition, combined consumption is ~9.8 L/100km (~29 mpg UK). Real-world figures vary significantly by driving style, but expect 25–30 mpg UK in mixed conditions. Performance tuning and aggressive driving reduce economy substantially.
Yes. The CYR5 is an interference engine. If the timing chain fails, pistons can contact open valves, causing severe internal damage. Immediate attention to timing rattles is critical to avoid costly repairs.
Ford specifies 5W-30 synthetic oil meeting WSS-M2C949-B standard. Change intervals should not exceed 15,000 km to ensure proper chain lubrication and prevent turbo wear. Using incorrect oil increases risk of fuel system and timing system failure.
