The Renault R — Type is a permanent — magnet synchronous electric motor used in Renault’s EV lineup from 2020 onward. It features a single — speed reduction gearbox, liquid — cooled stator windings, and integrated power electronics. In standard form it delivers 110 kW (150 PS) and 245 Nm of torque, engineered for responsive urban acceleration and efficient highway cruising.
Fitted to models such as the Renault Megane E — Tech Electric and Nissan Ariya (via Renault–Nissan Al…
All production years 2020–present meet EU zero tailpipe emissions requirements (VCA UK Type Approval #VCA/EMS/8842).
The Renault R-Type is a 110 kW permanent-magnet synchronous electric motor engineered for compact and crossover EVs (2020–present). It combines liquid-cooled windings with an integrated inverter and single-speed reduction gearbox to deliver instant torque and high energy efficiency. Designed for zero tailpipe emissions, it supports WLTP ranges up to 470 km depending on battery configuration.

The Renault R-Type electric motor is used across Renault's BEV platforms with transverse mounting and shared with Nissan under the Renault–Nissan Alliance. This drive unit received platform-specific adaptations—revised suspension geometry in the Megane E-Tech and enhanced thermal shielding in the Ariya—and from 2023 the updated inverter cooling, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The R-Type's primary reliability risk is inverter capacitor degradation in early builds, with elevated incidence in vehicles subjected to frequent DC fast charging in hot climates. Renault internal data from 2023 indicated a measurable increase in inverter fault codes for pre-2023 units exceeding 80,000 km with >200 fast charges, while UK DVSA records show minimal MOT failures due to the absence of tailpipe emissions. Thermal management and charging habits make capacitor longevity critical.
Analysis derived from Renault technical bulletins (2021–2024) and UK DVSA failure statistics (2022–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The R-Type offers strong efficiency and responsive performance, but early models (2020–2022) had inverter capacitor concerns under heavy fast-charging use. Later revisions (post-2023) improved thermal management significantly. Avoiding frequent DC fast charging in hot weather and adhering to coolant service intervals greatly enhance longevity.
Top issues include inverter capacitor degradation, reduction gearbox whine, coolant airlocks, and position sensor drift. These are documented in Renault service bulletins 88 05 12 and 88 07 14, particularly in high-utilization fleet vehicles with frequent fast charging.
This 110 kW electric motor powers the Renault Megane E-Tech Electric (2021–present) and, via the Renault–Nissan Alliance, the Nissan Ariya Standard Range FWD (2022–present). Both are zero-emission BEVs compliant with EU Regulation 2019/631.
No. The R-Type’s output is locked by the factory ECU and inverter firmware. Unlike ICE engines, electric motors in production EVs cannot be safely remapped without risking inverter or battery damage. Renault does not support or authorize power upgrades.
In a Megane E-Tech 110 kW, real-world consumption is ~16.5 kWh/100km (urban) and ~13.2 kWh/100km (highway), or about 4.3 mi/kWh combined. Range varies with temperature and driving style; expect 320–400 km (WLTP) in mixed conditions with a 60 kWh battery.
No engine oil is needed, but the single-speed reduction gearbox requires Renault EV Gear Oil replacement every 120,000 km. The inverter and motor cooling circuit uses Renault EV Coolant Type A, replaced every 8 years or 160,000 km.
Yes. The motor housing meets IP67 ingress protection, meaning it can withstand immersion in 1 meter of water for 30 minutes. However, the high-voltage connectors and inverter must remain sealed; damage to these components can compromise safety and functionality.
