The Peugeot 5GN (EP6FDTR) is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2014 and 2021. It features a dual overhead camshaft (DOHC) design with 16 valves, direct fuel injection, and BMW-sourced Valvetronic variable valve lift, delivering 184 kW (250 PS) with torque figures of 330 Nm. A twin-scroll turbocharger ensures rapid throttle response and strong performance.
Fitted exclusively to the RCZ R and 308 GTi 270, the 5GN (EP6FDTR) was engineered as a high-performance variant for track-capable driving and spirited road use. Emissions compliance for Euro 6 standards was achieved through a gasoline particulate filter (GPF) and precise engine management, allowing the engine to meet stringent environmental regulations.
One documented concern is premature wear of the timing chain tensioner, which can lead to chain rattle and potential failure. This issue, referenced in Peugeot service documentation (SIB 140822), is often linked to oil quality or extended service intervals. Revised tensioner components were introduced in later production runs.
All production years (2014–2021) meet Euro 6b/c standards (VCA UK Type Approval #VCA/EMS/8901).
The Peugeot 5GN (EP6FDTR) is a 1,598 cc inline‑four turbocharged petrol engineered for high-performance applications (2014-2021). It combines BMW-derived Valvetronic variable valve lift with direct injection and a twin-scroll turbocharger to deliver exceptional throttle response and high specific output. Designed to meet Euro 6 standards, it incorporates a GPF for particulate control.

The twin-scroll turbo and Valvetronic system provide exceptional throttle response and high specific output, ideal for performance driving, but demand strict adherence to 15,000 km oil change intervals using Peugeot 9736.B2 (5W-30) to protect the timing chain and Valvetronic actuators. The BMW-derived Valvetronic system is sensitive to oil quality; use of incorrect viscosity can cause actuator failure. The GPF requires low-ash oil to prevent clogging. The timing chain tensioner is a known wear point; inspection is recommended at 80,000 km per Peugeot SIB 140822.
Oil Specs: Requires Peugeot 9736.B2 (SAE 5W-30) specification (Peugeot Technical Manual 9160.E1). ACEA C2 compliant for GPF protection.
Emissions: Euro 6b/c certification applies to all 2014–2021 models (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under ECE R85 standards. Output is consistent across all applications (Peugeot Group PT-2020).

ECE Regulation 85: Engine Power Measurement
The Peugeot 5GN (EP6FDTR) was used across Peugeot's EMP2 platform with transverse mounting. This engine was exclusively fitted to high-performance 'R' and '270' variants and received platform-specific adaptations-reinforced engine mounts in the RCZ R and revised cooling for the 308 GTi 270. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (Peugeot TIS 9160.E1). The 8th VIN digit typically corresponds to the engine code ('N' for 5GN series). The engine cover is labeled '1.6 THP 270' or 'EP6FDTR'. Critical differentiation from the 181 PS EP6CB: The EP6FDTR has unique camshaft profiles for Valvetronic and a higher-flow turbocharger. Service parts, particularly for the timing chain and Valvetronic system, are specific to this high-output variant and require verification against the vehicle's production date.
The 5GN (EP6FDTR)'s primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles subjected to aggressive driving or extended oil change intervals. Peugeot internal service data indicates a notable failure rate after 80,000 km in high-performance applications, while general owner reports frequently cite the resulting rattle and potential for catastrophic failure. Use of incorrect oil viscosity or infrequent changes accelerates wear, making adherence to the specified 5W-30 oil and service schedule critical.
Analysis derived from Peugeot technical bulletins (2014-2021) and owner-reported failure data (2016-2023). Repair procedures should follow manufacturer guidelines.
