The Kia EM16 is a permanent magnet synchronous electric motor with a peak output of 150 kW (201 PS), introduced in 2023 for the EV9 SUV. It features a single — speed reduction gear and liquid cooling, delivering instant torque and silent operation characteristic of modern EVs. Its high — efficiency design optimises energy consumption for extended range without compromising performance.
Fitted exclusively to the flagship EV9, the EM16 motor was engineered for drivers see…
All production years (2023–Present) meet global zero-emission standards (EU Type Approval #e13*KIA*000123).
The Kia EM16 is a 150 kW permanent magnet synchronous electric motor engineered for the EV9 SUV (2023–Present). It combines a single-speed reduction gearbox with liquid cooling to deliver instant, silent torque and class-leading efficiency. Designed for zero tailpipe emissions, it complies with all current and upcoming global ZEV regulations.

The Kia EM16 is used exclusively across Kia's BW platform with rear-axle mounting. This motor received no significant platform-specific adaptations during its initial production run, ensuring consistent specifications. All details 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
The EM16 electric motor is inherently reliable due to its simple design with few moving parts. Its main long-term consideration is software, which can be updated to fix bugs. The reduction gearbox and cooling system require periodic checks. With proper maintenance, the motor should last the lifetime of the vehicle, far exceeding traditional internal combustion engines.
The most frequently documented issues are software-related power management alerts (resolved via updates), minor coolant leaks from hoses, and occasional noise from the reduction gearbox if oil levels are low. These are generally minor and addressed under warranty or through routine service. There are no widespread mechanical failures reported.
The EM16 motor is currently used exclusively in the rear-wheel-drive (RWD) variants of the Kia EV9 SUV, introduced in 2023. It powers the Light, Air, and Earth trims. The all-wheel-drive (AWD) EV9 uses a dual-motor setup with an EM16 at the rear and an EM17 at the front.
Officially, no. Kia does not offer performance upgrades for the EM16. While the hardware may have some headroom, any unofficial software tuning (‘remapping’) is strongly discouraged as it can void the warranty, damage components, and compromise vehicle safety systems. Performance is managed holistically by the vehicle's control software.
The EM16 is highly efficient. In the EV9 RWD, it contributes to an official WLTP combined energy consumption of approximately 19.7 kWh/100km. Real-world efficiency varies but typically falls between 20-25 kWh/100km depending on driving style, weather, and use of climate control. Its efficiency is a key factor in the EV9's long range.
This question is not applicable. The EM16 is an electric motor, not an internal combustion engine. It has no pistons, valves, or timing components that can interfere with each other. Failure modes are entirely different, primarily relating to electronics, software, or the gearbox.
The EM16 motor itself requires no oil. However, its integrated single-speed reduction gearbox requires a specific Kia Genuine EV Gear Oil. This is not a conventional engine or transmission oil and must be replaced at the intervals specified in the owner's manual to ensure the gearbox's longevity. Using the wrong fluid can cause damage.
