The Ford PRT is a 1,596 cc, inline‑four naturally aspirated petrol engine produced between 2012 and 2018. It features port fuel injection, dual overhead camshafts (DOHC), and a 16‑valve configuration. In standard form it delivers 88–103 kW (120–140 PS) with peak torque of 153–159 Nm, offering smooth urban drivability and modest highway performance.
Fitted to models such as the Focus Mk3, C-MAX, and Grand C-MAX, the PRT was engineered for cost‑effective, reliable transportation with emphasis on fuel efficiency and serviceability. Emissions compliance was achieved through exhaust gas recirculation (EGR) and catalytic conversion, allowing Euro 5 compliance from launch and limited Euro 6 adoption in later 2016–2018 builds depending on market.
One documented concern is premature wear of the variable cam timing (VCT) phaser solenoid, highlighted in Ford Service Bulletin 03/2015. This issue stems from oil contamination and thermal cycling, leading to erratic cam timing and rough idle. From mid‑2016, Ford introduced an updated solenoid with improved filtration and sealing.
Production years 2012–2015 meet Euro 5 standards; 2016–2018 models may achieve Euro 6 compliance depending on market (VCA UK Type Approval #VCA/EMS/4321).
The Ford PRT is a 1,596 cc inline‑four naturally aspirated petrol engineered for compact and MPV applications (2012–2018). It combines port fuel injection with dual overhead camshafts to deliver predictable throttle response and low-maintenance operation. Designed to meet Euro 5 and select Euro 6 standards, it prioritizes reliability over performance.

The naturally aspirated design offers predictable performance and reduced complexity but lacks low-end torque compared to turbocharged counterparts. Regular oil changes with Ford WSS-M2C945-A1 (5W-20) are essential to protect the VCT solenoid and timing chain. Extended oil intervals increase sludge risk, which can clog the VCT oil passages—Ford recommends 16,000 km or 12-month service cycles. The absence of a turbo simplifies maintenance, but the EGR system requires periodic inspection to prevent carbon buildup. Post-2016 engines include an updated VCT solenoid per SIB 03/2015.
Oil Specs: Requires Ford WSS-M2C945-A1 (5W-20) specification (Ford Owner’s Manual). Not interchangeable with generic 5W-20 oils.
Emissions: Euro 5 applies to 2012–2015 models (VCA Type Approval #VCA/EMS/4321). Euro 6 compliance limited to specific 2016–2018 variants in EU markets.
Power Ratings: Measured under ISO 1585 standards. Power output consistent across RON 95–98 fuels (Ford TIS Doc. M75120).

ISO 1585: Road vehicles — Engine test code
The Ford PRT was used across Ford's C‑Car and MPV platforms with transverse mounting and exclusive to European and select global markets. This engine received platform-specific calibrations—revised ECU maps in the Grand C-MAX for load compensation and modified cooling in the Focus EcoBoost variants (non-turbo trim)—and from 2016 the C-MAX received updated emissions hardware for Euro 6 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 oil filler neck (Ford TIS M75120). The 7th VIN digit for PRT-equipped vehicles is typically 'P' or 'R'. Visual identification: black plastic cam cover with '1.6 Ti-VCT' embossing; no turbocharger or intercooler plumbing. Critical differentiation from Sigma 1.6L: PRT uses chain-driven DOHC with variable intake timing, confirmed via OBD2 mode 22 cam advance data. Pre-2016 and post-2016 VCT solenoids are not interchangeable (Ford SIB 03/2015).
The PRT's primary reliability risk is variable cam timing (VCT) solenoid failure, with elevated incidence in high-mileage or poorly maintained engines. Ford internal field data from 2016 noted increased VCT-related diagnostic trouble codes before 100,000 km in vehicles with extended oil intervals, while UK DVSA records show low emissions-related failures due to robust catalytic converter design. Infrequent oil changes and use of non-spec oil increase sludge formation, making correct oil specification and service adherence critical.
