The Renault Z7W 712 is a 3,791 cc, V6 naturally aspirated petrol engine produced between 2015 and 2020. It features port fuel injection, dual overhead camshafts (DOHC) with variable valve timing on both intake and exhaust camshafts, and a 24‑valve architecture. In standard form it delivers 224 kW (305 PS) and 385 Nm of torque, engineered for high‑rpm power delivery and refined performance in premium applications.
Fitted to flagship models such as the Talisman Initiale Pa…
All production years (2015–2020) meet Euro 6b standards .
The Renault Z7W 712 is a 3,791 cc V6 naturally aspirated petrol engine engineered for premium large sedans and MPVs (2015–2020). It combines port fuel injection with dual overhead camshafts and dual‑VVT (intake and exhaust) to deliver linear high‑rpm power and refined grand touring performance. Designed to meet Euro 6b standards, it balances performance with regulated emissions.

The Renault Z7W 712 was used exclusively in Renault's premium large platforms with longitudinal mounting and no cross-manufacturer licensing. This engine received platform-specific adaptations—reinforced subframes in the Talisman and revised engine mounts in the Espace V—and from 2018 the facelifted Espace V adopted updated ECU calibrations for smoother VVT transitions, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The Z7W 712 offers smooth high-revving power and excellent refinement, but early units (2015–2017) have known dual-VVT solenoid seal issues under sustained high-load use. Post-2017 revisions improved durability. With strict adherence to oil changes (Renault RN0710, every 15,000 km) and use of RON 98 fuel, it can be reliable beyond 200,000 km.
Top issues include dual-VVT solenoid seal leakage, catalytic converter degradation due to rich mixtures, intake manifold runner actuator failure, and secondary air injection pump faults. These are documented in Renault SIB 15C12 and TIS updates, not anecdotal reports.
The TCe 305 (Z7W 712) appears exclusively in the Talisman (2015–2020) and Espace V (2015–2020) in Initiale Paris trim. It was not shared with Nissan or other manufacturers.
Aftermarket ECU tuning is common on the Z7W-712 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for its class. In a Talisman TCe 305, expect ~13.2 L/100km (city) and ~8.1 L/100km (highway), or ~22 mpg UK combined. Real-world mixed driving typically returns 20–24 mpg (UK), depending on driving style and maintenance.
Yes. Like all modern DOHC petrol engines, the Z7W 712 is an interference design. Timing chain failure (rare but possible) can cause piston-to-valve contact and catastrophic damage. However, the front-mounted chain has strong OEM durability when maintained properly.
Renault specifies RN0710 (5W-40) synthetic oil meeting ACEA A3/B4. This high-shear formulation protects dual-VVT components and ensures proper lubrication under thermal stress. Always use OEM-approved oil and change every 15,000 km or 12 months.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
