The Renault Z7W 707 is a 3,498 cc, 60° V6 naturally aspirated petrol engine produced between 2008 and 2015. It features sequential multi — point fuel injection, dual overhead camshafts (DOHC) per bank, and variable valve timing on the intake camshafts. In standard form it delivers 184 kW (250 PS) and 330 Nm of torque, with a redline of 6,800 rpm.
Fitted to premium models such as the Laguna III, Vel Satis, and Latitude, including the GT and Initiale Paris trims, the Z7W 707 was eng…
All production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7071).
The Renault Z7W 707 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 intake cam timing to deliver smooth, linear power and refined high-rpm operation. Designed to meet Euro 5 standards, it balances performance with emissions compliance.

The Renault Z7W 707 was used across Renault's Laguna III/Latitude platforms with longitudinal mounting and shared with Nissan for select FM platform applications. This engine received platform-specific adaptations—reinforced mounts in the Vel Satis and revised intake manifolds in the Latitude—and from 2012 the facelifted Laguna III Phase 2 adopted updated VVT actuators and oil galleries, creating interchange limits. Partnerships allowed Nissan's 350 GT to share core architecture. All adaptations are documented in OEM technical bulletins.
The Z7W 707's primary reliability risk is variable valve timing (VVT) actuator failure on early builds, with elevated incidence in vehicles using extended service intervals or incorrect oil viscosity. Renault internal data from 2013 indicated a notable share of pre-2012 engines requiring VVT replacement before 120,000 km, while UK DVSA records show occasional emissions-related MOT failures linked to catalyst degradation in high-mileage examples. Poor oil maintenance accelerates solenoid clogging and timing errors, making oil quality and service adherence critical.
Analysis derived from Renault technical bulletins (2011–2015) and UK DVSA failure statistics (2015–2023). 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 707 offers smooth V6 performance and refinement, but early models (2008–2011) are prone to VVT actuator failures. Post-2012 revisions significantly improved oil system durability. With consistent use of Renault RN0700 (5W-40) oil, regular 15,000 km service intervals, and proper ignition maintenance, well-maintained examples can exceed 200,000 km reliably.
Top issues include VVT actuator failure (pre-2012), catalytic converter degradation, valve cover oil leaks, and ignition coil wear. These are documented in Renault SIB 6021C and DVSA emissions data. Oil quality and service intervals heavily influence VVT and seal longevity.
The Z7W 707 powered the Laguna III, Vel Satis, and Latitude from 2008–2015 in 3.5 V6 trims. Nissan also used it in the Maxima QX 350 GT (2009–2013) under their alliance agreement. All meet Euro 5 emissions and feature longitudinal mounting.
Yes. ECU remaps typically yield +15–25 kW safely, as the naturally aspirated internals handle increased airflow. Supporting upgrades (intake, exhaust, ignition) enhance response. However, aggressive tuning without catalyst upgrades may trigger emissions faults, especially on post-2012 units.
In a Laguna 3.5 V6, expect ~12.5 L/100km (city) and ~7.8 L/100km (highway), or ~27 mpg UK combined. Real-world economy depends heavily on driving style, vehicle weight, and traffic conditions.
Yes. The Z7W 707 is an interference engine. If either timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. While chain failures are rare, any unusual noise or timing-related DTCs require immediate inspection.
Renault specifies 5W-40 synthetic oil meeting RN0700 (or ACEA A3/B4 equivalent). Always use high-quality oil to protect VVT actuators and timing chains. Change intervals should not exceed 15,000 km or 12 months to maintain oil pressure and solenoid function.
