All production years (2022–2025) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/8845).
The Renault E-Tech PHEV is a 1,598 cc inline‑four turbocharged petrol engine paired with dual electric motors and a 19.2 kWh battery, engineered for compact and crossover applications (2022–2025). It combines direct injection with a clutchless multi-mode transmission to deliver zero-emission urban driving and efficient hybrid highway performance. Designed to meet Euro 6d standards, it balances electric range with regulated emissions.

The Renault E-Tech PHEV was developed exclusively for Renault's CMF-EV and CMF-C platforms with transverse mounting and no cross-manufacturer licensing. This powertrain received platform-specific adaptations—reinforced subframes in the Austral and revised cooling ducting in the Mégane E-Tech—and from 2024 the updated control software improved electric-to-petrol transition smoothness, creating minor calibration interchange limits. All adaptations are documented in OEM technical bulletins.
The E-Tech PHEV's primary reliability risk is clutchless transmission input shaft bearing wear, with elevated incidence in vehicles subjected to frequent urban electric-only driving with abrupt petrol re-engagement. Renault internal field data (2024) indicated a measurable increase in bearing noise complaints for vehicles with >70% electric-mode usage before 60,000 km, while UK DVSA MOT data shows no significant emissions-related failures due to robust GPF integration. Extended high-state-of-charge parking in hot climates accelerates battery degradation, making thermal management critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The E-Tech PHEV offers excellent electric range and smooth hybrid transitions, but early units (2022–2023) have known transmission input shaft bearing wear under frequent urban electric use. Post-2024 revisions improved durability. With strict adherence to oil changes (Renault RN0720, every 20,000 km) and balanced driving modes, it can be reliable beyond 150,000 km.
Top issues include transmission input shaft bearing wear, battery thermal management faults, GPF regeneration interference due to low engine use, and DC-DC converter overheating. These are documented in Renault SIB 22H03 and TIS updates, not anecdotal reports.
The E-Tech PHEV 245 appears in the Mégane E-Tech Plug-in (2022–2025) and Austral (2022–2025). It is distinct from the mild-hybrid E-Tech variants and is not shared with Nissan or other manufacturers.
Limited tuning potential exists. ECU remaps may yield +5–10 kW by optimizing petrol engine output, but the hybrid control strategy and electric motor limits are tightly integrated. Significant power increases are not OEM-supported and risk inverter or battery damage.
Exceptional when charged regularly. In mixed driving with daily charging, expect ~2.0 L/100km (combined), or ~140 mpg UK equivalent. Without charging, consumption rises to ~6.5 L/100km (~43 mpg UK). Real-world economy depends heavily on electric usage patterns and climate.
Yes. The petrol component (H4F turbo) is an interference design. Timing chain failure (rare) can cause piston-to-valve contact. However, the chain is front-mounted and robust when maintained with correct oil and intervals.
Renault specifies RN0720 (5W-30) synthetic oil meeting ACEA C2/C3. This low-SAPS formulation protects the GPF and ensures proper lubrication of the hybrid transmission interface. Always use OEM-approved oil and change every 20,000 km or 12 months.
