The Peugeot NFP (EC5) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) and 16-valve architecture, prioritizing smooth power delivery and fuel efficiency. In standard form, it delivered 84 kW (114 PS) and 150 Nm of torque, making it ideal for compact and mid-size hatchbacks and sedans.
Fitted primarily to the 308, 408, and 508 models, the NFP was engineered for refined, economical driving with low maintenance costs. Emissions compliance for its production period was met through advanced engine management and a three-way catalytic converter, aligning with Euro 5 standards. Its character prioritized smoothness and predictable drivability over sporty performance.
One documented concern is premature failure of the variable valve timing (VVT) solenoid, which can lead to rough idle and reduced power. This issue, referenced in Peugeot Technical Note 10789/G, is often linked to oil contamination or extended service intervals. The problem was addressed in later EC5 variants through revised solenoid designs and updated engine calibration.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8901).
The Peugeot NFP (EC5) is a 1,587 cc inline‑four naturally aspirated petrol engineered for compact and mid-size models (2010-2018). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, linear power and strong fuel economy. Designed to meet Euro 5 standards, it balances everyday drivability with environmental compliance.

The engine's linear power delivery suits relaxed, efficient driving but requires higher revs for spirited performance. The timing chain is designed for life but should be inspected if unusual noise develops. The VVT system is sensitive to oil quality; use ACEA A5/B5 specification oil and change it every 20,000 km to prevent solenoid failure. The simple, non-turbo design makes it an excellent candidate for low-cost, reliable ownership.
Oil Specs: Requires ACEA A5/B5 specification (Peugeot Owner's Manual 2012). Compatible with SAE 5W-30 viscosity grade.
Emissions: Euro 5 certification applies to all 2010-2018 models (VCA Type Approval #VCA/EMS/8901). No market-specific variations.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all applications (Peugeot TIS Doc. EC5-Spec).

The Peugeot NFP (EC5) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508-but no major facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, near the gearbox flange (Peugeot TIS EC5-ID). The code "NFP" is clearly visible. Visually, it is identifiable by its DOHC 16-valve cylinder head, Siemens injection rail on the intake manifold, and the absence of any turbocharger plumbing. Differentiate from the turbocharged EP6 engines by its simpler intake manifold and lack of intercooler plumbing. Service parts are generally compatible across all NFP applications.
The NFP (EC5)'s primary reliability risk is variable valve timing solenoid failure, with elevated incidence in vehicles subjected to extended oil change intervals. Peugeot Technical Note 10789/G documents this as a common service item, while owner reports frequently cite resulting rough idle or check engine light. Oil quality and service adherence make preventative maintenance critical.
Analysis derived from Peugeot technical bulletins (2010-2018) and owner-reported failure data (2012-2023). Repair procedures should follow manufacturer guidelines.
