Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d .
The Renault Z7X 765 is a 3,791 cc V6 twin-turbocharged petrol engine engineered for lightweight sports applications (2018–2023). It combines direct fuel injection with dual overhead camshafts and dual-VVT to deliver high specific output and responsive mid-range torque. Designed to meet Euro 6d TEMP and Euro 6d standards, it balances performance with stringent emissions compliance.

The Renault Z7X 765 was developed exclusively for Alpine (a Renault Group brand) and used in the A110 sports car platform with mid-engine, transverse mounting. No cross-manufacturer licensing occurred. This engine received platform-specific adaptations—dry-sump lubrication, compact exhaust manifolds integrated with turbo housings, and reinforced bellhousing for the Getrag dual-clutch transmission. From 2021, the A110S variant adopted revised boost control maps but retained mechanical interchangeability. 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 765 offers exceptional power density and sports car responsiveness, but early units (2018–2020) have known HPFP drive pinion wear issues under sustained high-load use. Post-2020 revisions improved durability. With strict adherence to oil changes (Renault RN0720, every 15,000 km) and use of RON 98 fuel, it can be reliable beyond 150,000 km in road-focused applications.
Top issues include high-pressure fuel pump drive pinion wear, GPF clogging in urban use, turbo wastegate actuator drift, and dry-sump oil pump cavitation under extreme cornering. These are documented in Renault SIB 18C09 and TIS updates, not anecdotal reports.
The Z7X 765 is used exclusively in the Alpine A110 (2018–2023), including Pure, Legende, and S variants. Alpine is a Renault Group brand, but this engine is not fitted to mainstream Renault models or shared with Nissan.
Aftermarket ECU tuning is common on the Z7X-765 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 performance class. In an Alpine A110, expect ~11.5 L/100km (city) and ~7.2 L/100km (highway), or ~26 mpg UK combined. Real-world mixed driving typically returns 24–28 mpg (UK), depending on driving style and maintenance.
Yes. Like all modern DOHC petrol engines, the Z7X 765 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 RN0720 (5W-30) synthetic oil meeting ACEA C2/C3. This low-SAPS formulation protects the GPF and ensures proper lubrication of the HPFP drive. Always use OEM-approved oil and change every 15,000 km or 12 months.
