The Honda e:PT is a fully electric drive unit powering the Honda e:Ny1 and e:NS1, produced from 2023 to present. It features a single permanent — magnet synchronous motor integrated with a single — speed reduction gearbox, delivering 150 kW (204 PS) and 310 Nm of torque. This powertrain is designed for instant, silent acceleration and maximum energy efficiency in urban and highway environments.

All production years 2023–Present meet zero tailpipe emission standards globally .
The Honda e:PT is an integrated electric drive unit engineered for compact SUVs (2023-Present). It combines a high-efficiency permanent-magnet synchronous motor with a single-speed reduction gearbox to deliver instant torque and smooth, silent operation. Designed for zero tailpipe emissions, it prioritizes efficiency and low maintenance.

The Honda e:PT is used exclusively in Honda's dedicated EV platforms with transverse mounting. This drive unit was developed specifically for the e:N series and features unique components not shared with hybrid or ICE models. No licensing to other manufacturers has been documented. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
As a new electric drive unit, the e:PT is expected to be highly reliable due to its minimal moving parts. Its main documented service item is a software-related resolver calibration, easily fixed with an update. With no traditional engine or transmission to wear out, and adherence to software updates, the e:PT should offer excellent long-term reliability.
The most common reported issues are related to software calibration of the motor resolver sensor (causing warning lights), potential noise from the reduction gearbox bearings, coolant pump failure for the power electronics, and 12V auxiliary battery drain. These are documented in early service bulletins like E23-008 and are generally straightforward to diagnose and resolve.
The e:PT drive unit is currently used exclusively in the Honda e:Ny1 and e:NS1, which are Honda's dedicated global electric vehicles launched in 2023. These models are sold in various international markets, including Europe and Asia.
Tuning the e:PT for more power is not officially supported and is highly complex. It would require modifying the motor control unit software and potentially upgrading the battery and cooling systems, which could void the warranty and compromise safety. Honda does not offer performance upgrades for this unit.
The e:PT is highly efficient. In the e:Ny1, expect an energy consumption of around 15-18 kWh/100km (WLTP combined). Real-world efficiency is excellent in city driving due to regenerative braking and very good on the highway. Efficiency is significantly better than any internal combustion engine.
No, the e:PT does not require traditional engine oil changes. The reduction gearbox contains a sealed, lifetime-fill oil that does not need periodic replacement under normal operating conditions. However, the coolant for the power electronics and motor should be inspected periodically as per the maintenance schedule.
Maintenance for the e:PT is minimal. It includes periodic inspections of the drive unit for leaks or damage, checking and replacing the 12V auxiliary battery as needed, inspecting brake fluid, and ensuring the cooling system for the power electronics is functioning correctly. Software updates are also a critical part of maintenance.
