The Renault Z7W 709 is a 2,995 cc, V6 naturally aspirated petrol engine produced between 2010 and 2018. It features a dual overhead camshaft (DOHC) layout with 24 valves and sequential multi — point fuel injection. In standard form it delivers 177 kW (241 PS) and 300 Nm of torque, engineered for smooth high — rpm power delivery and refined cruising.
Fitted to models such as the Renault Laguna III, Latitude, and Talisman, the Z7W 709 was designed for executive — level refinement…
All production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/4567).
The Renault Z7W 709 is a 2,995 cc V6 naturally aspirated petrol engine engineered for executive sedans and large MPVs (2010–2018). It combines DOHC 24‑valve architecture with sequential multi‑point injection and variable valve timing to deliver smooth high‑rpm power and refined operation. Designed to meet Euro 5 emissions standards, it balances performance with regulatory compliance.

The Renault Z7W 709 was used across Renault's PL and CMF-C platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced sump in the Laguna III and modified exhaust routing in the Talisman—and from 2014 the Latitude facelift adopted updated VVT solenoids and ECU maps, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The Z7W 709's primary reliability risk is variable valve timing (VVT) solenoid failure, with elevated incidence in urban or short-trip driving conditions. Renault internal field data (2016) indicated a measurable uptick in VVT-related DTCs before 100,000 km in high-idle fleets, while UK DVSA records show catalytic converter degradation as the second-most common emissions-related MOT defect. Stop-start cycles and oil degradation make strict adherence to OEM oil specs critical.
Analysis derived from Renault technical bulletins (2010–2018) and UK DVSA failure statistics (2012–2020). 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 709 offers smooth performance and executive refinement, but early units (2010–2013) had VVT solenoid reliability concerns. Post-2014 revisions improved durability. With strict use of RN0700 oil and 15,000 km service intervals, it can be dependable beyond 200,000 km.
Top issues include VVT solenoid failure, catalytic converter degradation, timing chain guide wear, and intake manifold runner control faults. These are documented in Renault SIB 77 09 05 and DVSA emissions data. Oil quality and service adherence are critical mitigating factors.
The Z7W 709 powered the Renault Laguna III (2010–2015), Latitude (2010–2015), and Talisman Initiale Paris (2015–2018), all as the 3.0 V6 variant. It was not licensed to other manufacturers and is exclusive to Renault’s PL/CMF-C-platform executive vehicles.
Yes, moderately. Stage 1 ECU remaps typically yield +15–20 kW, though the naturally aspirated V6 has limited headroom. Supporting upgrades (performance exhaust, intake, ignition) are recommended beyond mild tuning. Aggressive tuning increases thermal stress on VVT and catalytic systems.
Official combined is ~9.8 L/100km (~29 mpg UK). Real-world mixed driving yields 10.5–11.5 L/100km (25–27 mpg UK). Highway efficiency can reach 8.2 L/100km (34 mpg UK), while city driving may exceed 13.0 L/100km.
Yes. Like all modern DOHC petrol engines, it is an interference design. Timing chain failure—though rare—can cause catastrophic valve/piston contact. Chain durability is generally good, but guide wear must be monitored.
Renault specifies RN0700 (ACEA A3/B4) 5W-40 synthetic oil. This high-SAPS formulation ensures proper VVT solenoid and cam lubrication. Never use low-SAPS C2/C3 oils, as they lack the anti-wear additives needed for variable valve timing systems.
