The Renault Z7U 700 is a 3,498 cc, V6 naturally aspirated petrol engine produced between 2010 and 2015. It features port fuel injection, dual overhead camshafts (DOHC) with variable valve timing on the intake side, and a 24‑valve architecture. In standard form it delivers 184 kW (250 PS) and 340 Nm of torque, engineered for smooth high‑rpm power delivery and refined highway cruising.

All production years (2010–2015) meet Euro 5 standards .
The Renault Z7U 700 is a 3,498 cc V6 naturally aspirated petrol engine engineered for large sedans and MPVs (2010–2015). It combines port fuel injection with dual overhead camshafts and intake-side variable valve timing to deliver smooth, linear power and refined highway performance. Designed to meet Euro 5 standards, it balances performance with regulated emissions.

The Renault Z7U 700 was used across Renault's large premium platforms with longitudinal mounting and shared with Nissan for select flagship applications. This engine received platform-specific adaptations—reinforced engine mounts in the Espace IV and revised exhaust manifolding in the Laguna III GT—and from 2014 the facelifted Latitude adopted updated ECU calibrations, creating minor interchange limits. Partnerships allowed Nissan's Maxima and Quest to use a closely related variant (VQ35DE-based, though not identical). 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 Z7U 700 offers smooth power delivery and excellent refinement, but early units (2010–2013) have known VVT actuator seal issues under frequent thermal cycling. Post-2013 revisions improved durability. With strict adherence to oil changes (Renault RN0700, every 15,000 km) and use of RON 95+ fuel, it can be reliable beyond 200,000 km.
Top issues include VVT actuator seal leakage, catalytic converter degradation due to rich mixtures, intake manifold runner sticking, and water pump impeller corrosion. These are documented in Renault SIB 10C08 and TIS updates, not anecdotal reports.
The 3.5 V6 250 (Z7U 700) appears in the Laguna III GT (2010–2015), Latitude (2010–2015), and Espace IV Initiale (2010–2014). It was not used in Nissan models despite platform sharing; Nissan employed its own VQ35DE in equivalent vehicles.
Aftermarket ECU tuning is common on the Z7U-700 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 Latitude 3.5 V6 250, expect ~12.5 L/100km (city) and ~7.8 L/100km (highway), or ~24 mpg UK combined. Real-world mixed driving typically returns 22–26 mpg (UK), depending on driving style and maintenance.
Yes. Like all modern DOHC petrol engines, the Z7U 700 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 RN0700 (5W-40) synthetic oil meeting ACEA A3/B4. This high-shear formulation protects VVT components and ensures proper lubrication under thermal stress. Always use OEM-approved oil and change every 15,000 km or 12 months.
