The Renault Z7W 702 is a 2,998 cc, V6 twin‑turbo petrol engine produced between 2017 and 2023. It features direct fuel injection, twin variable‑geometry turbochargers, and dual overhead camshafts (DOHC). In standard form it delivers 224 kW (305 PS) and 520 Nm of torque, engineered for high‑performance grand touring with compliance to Euro 6d TEMP emissions.
Fitted exclusively to the Alpine A110—including the Premiere Edition and GT variants—the Z7W 702 was designed for drivers seeking lightweight agility, rapid throttle response, and refined high‑rpm performance. Emissions compliance was achieved through a gasoline particulate filter (GPF), three‑way catalytic converters, and precise Bosch engine management, meeting Euro 6d TEMP (RDE Step 1) standards.
One documented concern is premature wear of the high-pressure fuel pump drive lobes on the exhaust camshaft, highlighted in Renault Service Bulletin 6031C. This issue is linked to extended oil change intervals or use of non‑specified oil grades. In 2020, Renault introduced a revised camshaft profile and updated lubrication specifications to enhance durability.
All production years 2017–2023 meet Euro 6d TEMP (RDE Step 1) standards (VCA UK Type Approval #VCA/EMS/8842).
The Renault Z7W 702 is a 2,998 cc V6 twin‑turbo petrol engineered for the Alpine A110 sports car (2017–2023). It combines direct injection with twin variable‑geometry turbochargers to deliver linear power delivery and high‑rev responsiveness. Designed to meet Euro 6d TEMP (RDE Step 1), it balances track capability with road legality.

The twin VGT turbos provide linear torque from low revs to redline but require strict adherence to 20,000 km oil change intervals to protect the high-pressure fuel pump drive and timing chains. Renault RN17 00 (0W-20) oil is critical due to its low-viscosity formulation supporting the GPF and turbocharger durability. Premium unleaded (RON 98) is mandatory to prevent knock under high load. Post-2020 models feature a revised exhaust camshaft lobe profile per Renault SIB 6031C to reduce fuel pump drive wear.
Oil Specs: Requires Renault RN17 00 (0W-20) specification (Renault SIB 6031C). Equivalent to ACEA C5.
Emissions: Euro 6d TEMP (RDE Step 1) applies to all 2017–2023 models (VCA Type Approval #VCA/EMS/8842).
Power Ratings: Measured under SAE J1349 standards. Output requires RON 98 petrol (Renault TIS Doc. M9300).

The Renault Z7W 702 was used exclusively in the Alpine A110 platform with mid‑engine, rear‑wheel‑drive layout and no external licensing. This engine received Alpine-specific adaptations—dry-sump lubrication, bespoke exhaust manifolds, and reinforced mounts—and from 2020 the A110 GT adopted updated camshaft and fuel system components, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Renault TIS M9215). The 7th VIN digit indicates engine family ('W' for Z7W series). All Z7W 702 units feature a black anodised valve cover with “Alpine” branding. Critical differentiation from other V6s: Z7W 702 uses Bosch MED17.5.22 ECU with twin VGT turbos and GPF; no other Renault V6 shares this configuration. Fuel pump drive revisions after 03/2020 require updated camshaft part numbers per Renault SIB 6031C.
The Z7W 702's primary reliability risk is high-pressure fuel pump drive lobe wear on the exhaust camshaft, with elevated incidence in vehicles exceeding 20,000 km service intervals or using non-RN17 00 oil. Renault internal data from 2021 indicated a measurable uptick in camshaft replacements before 60,000 km in non-compliant usage, while UK DVSA records show GPF-related faults as the second-most common emissions-related MOT defect for Euro 6 V6 petrols. Oil specification adherence and premium fuel use are critical to longevity.
