The Renault Z7X 755 is a 3,498 cc, 60° V6 naturally aspirated petrol engine produced between 2010 and 2018. It features sequential multi — point fuel injection, dual overhead camshafts (DOHC) per bank, and variable valve timing on both intake and exhaust camshafts. In standard form it delivers 177 kW (241 PS) and 330 Nm of torque, with a redline of 6,750 rpm.
Fitted to premium models such as the Laguna III, Latitude, and Talisman, including the Initiale Paris and GT trims, the Z…
All production years 2010–2018 meet Euro 5 standards .
The Renault Z7X 755 is a 3,498 cc V6 naturally aspirated petrol engine engineered for executive sedans and large MPVs (2010–2018). It combines sequential multi-point injection with dual variable 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 Z7X 755 was used across Renault's Laguna III/Talisman platforms with longitudinal mounting and shared with Nissan for select FM platform applications. This engine received platform-specific adaptations—reinforced mounts in the Latitude and revised intake manifolds in the Talisman—and from 2014 the facelifted Laguna III Phase 2 and early Talisman adopted updated dual 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Z7X 755 offers smooth V6 performance and refinement, but early models (2010–2013) are prone to dual VVT actuator failures. Post-2014 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 dual VVT actuator failure (pre-2014), catalytic converter degradation, valve cover oil leaks, and ignition coil wear. These are documented in Renault SIB 6023D and DVSA emissions data. Oil quality and service intervals heavily influence VVT and seal longevity.
The Z7X 755 powered the Laguna III, Latitude, and Talisman from 2010–2018 in 3.5 V6 trims. Nissan also used it in the Maxima QX 350 GT (2012–2015) under their alliance agreement. All meet Euro 5 emissions and feature longitudinal mounting.
Aftermarket ECU tuning is common on the Z7X-755 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.
In a Talisman 3.5 V6, expect ~12.2 L/100km (city) and ~7.5 L/100km (highway), or ~28 mpg UK combined. Real-world economy depends heavily on driving style, vehicle weight, and traffic conditions.
Yes. The Z7X 755 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 dual VVT actuators and timing chains. Change intervals should not exceed 15,000 km or 12 months to maintain oil pressure and solenoid function.
