The Renault Z7W 713 is a 3,498 cc, V6 naturally aspirated petrol engine produced between 2008 and 2015. It features dual overhead camshafts (DOHC), 24 valves, and sequential multi — point fuel injection. In standard form it delivers 177 kW (241 PS) and 330 Nm of torque, with smooth linear power delivery ideal for executive and grand tourer applications.
Fitted to models such as the Laguna III and Vel Satis, including variants like the 3.5 V6, the Z7W 713 was engineered for refi…
All production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/3756).
The Renault Z7W 713 is a 3,498 cc V6 naturally aspirated petrol engine engineered for executive sedans and grand tourers (2008–2015). It combines sequential multi-point injection with variable valve timing on the intake camshafts to deliver linear power and refined operation across the rev range. Designed to meet Euro 5, it balances performance with emissions compliance.

The Renault Z7W 713 was used across Renault's D platform with longitudinal mounting. This engine received platform-specific adaptations—reinforced engine mounts in the Laguna III and revised exhaust manifolds in the Vel Satis—and from 2011 the updated Laguna III Phase 2 adopted revised VVT actuators, creating limited interchangeability. All adaptations are documented in OEM technical bulletins.
The Z7W 713's primary reliability risk is VVT actuator seal degradation, with elevated incidence in frequent short-trip usage. Renault internal quality data from 2012 indicated a measurable uptick in VVT-related warranty claims before 90,000 km in urban fleets, while UK DVSA MOT records show catalytic converter efficiency as the second-most common petrol issue for this engine. Thermal cycling and oil contamination accelerate seal hardening, making oil quality and driving pattern critical.
Analysis derived from Renault technical bulletins (2009–2015) and UK DVSA failure statistics (2010–2023). 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 713 offers smooth performance and strong refinement, but early units (2008–2011) show higher VVT actuator seal wear under short-trip conditions. Post-2011 revisions improved seal durability. With proper maintenance—especially oil changes every 15,000 km and using RN0700 oil—longevity is generally good.
Top issues include VVT actuator seal failure, timing chain guide wear, catalytic converter degradation, and intake manifold runner sticking. These are documented in Renault SIB 15A002 and DVSA MOT data. Most stem from driving patterns or oil maintenance rather than inherent design flaws.
The Z7W 713 powers the Laguna III (3.5 V6, 2008–2015) and Vel Satis (3.5 V6, 2008–2010). Both are longitudinal-mounted on the D platform and comply with Euro 5 emissions.
Yes. Stage 1 ECU remaps typically yield +15–20 kW safely, as the naturally aspirated V6 tolerates moderate ignition and fueling adjustments. However, aggressive tuning without upgraded exhaust or cooling risks catalyst damage. Always use supporting modifications and high-octane fuel.
Official NEDC combined figures range from 10.1–10.7 L/100km (≈28–26 mpg UK). Real-world mixed driving typically achieves 24–27 mpg UK. Highway cruising can exceed 29 mpg UK, while city use may drop to 21 mpg UK depending on traffic.
Yes. The Z7W 713 is an interference engine. If either timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the dual-chain design is robust with proper oil maintenance.
Renault specifies RN0700 (5W-40) synthetic oil. This meets ACEA A3/B4 standards and is essential for high-temperature stability and VVT actuator protection. Change intervals should not exceed 15,000 km or 12 months, especially with short-trip driving.
