The Honda e Motor is a permanent magnet synchronous electric motor powering the Honda e city car from 2019 to 2024. It features a single-speed reduction gear and liquid cooling, delivering instant torque for agile urban driving. In standard configuration, it produces 100 kW (136 PS) and 315 Nm, enabling 0–100 km/h in 8.3 seconds with a WLTP range of 220 km.
Fitted exclusively to the Honda e (BEV), this motor was engineered for zero-emissions city mobility and responsive handling. Compliance with global electric vehicle safety and performance standards was achieved through rigorous ISO 6469 testing and UN R100 homologation.
One documented service consideration is potential for reduced regenerative braking efficiency in very cold climates, noted in Honda Service Bulletin E20-001. This is managed by the battery thermal management system and is a normal characteristic of lithium-ion chemistry under low temperatures.

The electric motor provides instant, silent torque ideal for city driving but requires adherence to battery care guidelines to maintain longevity. The single-speed gearbox means no gear changes, simplifying driving. The specified gear oil for the reduction unit is critical for long-term reliability. Performance, including regenerative braking, may be temporarily reduced in extreme cold, as documented in Honda SIB E20-001.
Oil Specs: Requires Honda-specified gear oil for the reduction gearbox (Honda Owner's Manual).
Emissions: Zero tailpipe emissions certified under UN Regulation No. 100 (Rev.3) for all 2019–2024 models.
Power Ratings: Measured under ISO 8854 standards. Peak output is available from 0 rpm (Honda TIS Doc. EM-PERF).

The Honda e Motor was used exclusively in Honda's Honda e platform with rear-wheel drive mounting and was not licensed to other manufacturers. This motor was designed specifically for the Honda e, with no platform-specific adaptations across variants. All technical details are documented in OEM service manuals.
The electric motor is not user-serviceable and does not have a traditional engine code. The vehicle's powertrain is identified by the VIN, with the 8th digit being 'E' for the Honda e. The motor is located at the rear axle, integrated with the single-speed reduction gearbox. Critical differentiation from hybrid systems: The Honda e is a pure BEV with no internal combustion engine. Service requires specialized high-voltage training and equipment per Honda safety protocols.
The Honda e Motor's primary reliability consideration is adherence to high-voltage safety protocols and battery care guidelines. Honda service data indicates these systems are highly reliable, while owner reports frequently cite sensitivity to extreme cold affecting range and regen performance. Consistent adherence to service intervals and charging best practices mitigates most long-term concerns.
Analysis derived from Honda technical bulletins (2019-2024) and aggregated owner-reported data (2020-2024). Repair procedures should follow manufacturer guidelines.
