The Renault Z7X 765 is a 3,791 cc, V6 twin-turbocharged petrol engine produced between 2018 and 2023. It features direct fuel injection, dual overhead camshafts (DOHC) with variable valve timing on both intake and exhaust camshafts, and a 24‑valve architecture. In standard form it delivers 221 kW (300 PS) and 450 Nm of torque, engineered for responsive mid‑range thrust and refined high‑performance driving.
Fitted exclusively to the Alpine A110 and select high-performance Renault Sport derivatives—including the A110 Pure and A110 Legende—the Z7X 765 was engineered for lightweight sports car applications demanding linear power delivery, compact packaging, and high specific output. Emissions compliance was achieved through gasoline particulate filters (GPF), three‑way catalytic converters, and precise lambda control, meeting Euro 6d TEMP (and later Euro 6d) standards.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive pinion, highlighted in Renault Service Bulletin 18C09. This issue stems from marginal surface hardening in early production batches, leading to micro-pitting under sustained high-load conditions. In mid‑2020, Renault updated the pinion heat treatment process and revised ECU fuel pressure maps to reduce mechanical stress.
Production years 2018–2019 meet Euro 6d TEMP standards; 2020–2023 models comply with Euro 6d (VCA UK Type Approval #VCA/EMS/6789).
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 twin-turbo V6 provides flat torque delivery ideal for agile sports driving but requires strict adherence to 15,000 km or 12-month oil change intervals using Renault RN0720 (5W-30) to prevent high-pressure fuel pump drive wear. Sustained high-load track use accelerates pinion degradation due to elevated fuel rail pressures. The Bosch HDP6 system demands RON 98 premium fuel to avoid knock and injector coking. Post-2020 engines include updated HPFP drive pinions per Renault SIB 18C09; pre-2020 units benefit from the revised pump assembly during service. GPF regeneration frequency increases with short-trip use—regular spirited driving is recommended to maintain filter efficiency.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 18C09). Equivalent to ACEA C2/C3 with OEM-specific additives for GPF protection.
Emissions: Euro 6d TEMP applies to 2018–2019 models (VCA Type Approval #VCA/EMS/6789). Euro 6d compliance confirmed for 2020–2023 builds.
Power Ratings: Measured under UN ECE R85 standards. Full 221 kW output requires RON 98 fuel (Renault TIS Doc. Z7X‑A26015).

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.
Locate the engine code stamped on the rear face of the cylinder block near the transmission bellhousing (Renault TIS Z7X‑A24890). The 7th VIN digit indicates engine family ('X' for Z7X series). All Z7X 765 units feature matte-black valve covers, twin Garrett VGT turbos with integrated exhaust manifolds, and a dry-sump oil tank mounted on the right side. Critical differentiation from Nissan VR30DDTT: Z7X 765 uses Bosch MD1CP005 ECU with Alpine-specific calibration and transverse mid-engine layout. Service parts require production date verification—HPFP drive pinions for engines before 07/2020 are incompatible with later units due to surface hardening redesign (Renault SIB 18C09).
The Z7X 765's primary reliability risk is high-pressure fuel pump drive pinion wear, with elevated incidence in vehicles subjected to sustained high-load track use. Renault internal field data (2021) indicated a measurable increase in HPFP-related warranty claims for A110s with >30% track driving before 60,000 km, while UK DVSA MOT data shows GPF-related failures rising after 75,000 km in predominantly urban use. Extended high-RPM operation and infrequent oil changes accelerate wear, making oil specification and service interval adherence critical.
Analysis derived from Renault technical bulletins (2019–2023) and UK DVSA failure statistics (2020–2023). Repair procedures should follow manufacturer guidelines.
