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.

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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Z7W 702 offers exceptional performance and refinement, but early units (2017–2020) had high-pressure fuel pump drive lobe wear concerns. Post-2020 revisions improved camshaft durability. Longevity heavily depends on using RN17 00 (0W-20) oil, adhering to 20,000 km oil changes, and using RON 98 fuel exclusively.
Top issues include exhaust camshaft-driven high-pressure fuel pump wear, GPF clogging, turbo actuator calibration drift, and PCV oil separator failure. These are documented in Renault service bulletins and correlate with DVSA MOT failure data for Euro 6 V6 petrol engines.
The Z7W 702 is used exclusively in the Alpine A110 (2017–2023), including Premiere Edition, Pure, Legende, GT, and S variants. It is not shared with any other Renault, Nissan, or Dacia models.
Yes, ECU remaps can safely increase output to ~260–270 kW (350–370 PS) on stage 1, as the forged internals and twin-turbo architecture are robust. However, tuning increases stress on the fuel system, GPF, and cooling circuits, so supporting upgrades are often recommended by tuners.
Official WLTP combined figures range from 8.4–9.1 L/100km (34–31 mpg UK). Real-world mixed driving typically yields 9.5–11.0 L/100km (30–26 mpg UK), depending on driving style, track use, and GPF regeneration cycles.
Yes. The Z7W 702 is an interference engine. If either timing chain fails or jumps, piston-to-valve contact can cause catastrophic internal damage. However, the dual front-mounted chains are generally robust with proper maintenance.
Renault specifies RN17 00-compliant 0W-20 low-SAPS synthetic oil. This is critical for GPF compatibility, turbocharger protection, and fuel pump drive lubrication. Change intervals should not exceed 20,000 km or 12 months, whichever comes first.
