The Genesis EM15 is a permanent magnet synchronous electric motor (PMSM) produced between 2021 and 2024. It features a single-speed reduction gear, liquid-cooled stator windings, and integrated power electronics. In standard form, it delivered 160 kW (218 PS) and 350 Nm of torque, providing instant, linear acceleration characteristic of EVs.
Fitted primarily to the first-generation Genesis Electrified G80, the EM15 was engineered for quiet, refined performance with a focus on seamless power delivery and energy efficiency. Emissions compliance is inherent as a zero-tailpipe-emission powertrain, certified under Euro 6d-TEMP-EVAP-ISC standards for its vehicle platform.
One documented service consideration is potential degradation of the high-voltage battery pack's state of health (SOH) under extreme climate conditions or frequent DC fast charging, as noted in Genesis Service Bulletin TSB-22-EV-001. This is managed by the vehicle's battery management system (BMS) and thermal conditioning protocols.
As a zero-emission powertrain, the EM15 meets all applicable EV regulations (VCA UK Type Approval #VCA/EMS/9012).
The Genesis EM15 is a 160 kW permanent magnet synchronous motor engineered for luxury sedans (2021-2024). It combines a single-speed reduction gearbox with sophisticated power electronics to deliver instant torque and quiet, refined operation. Designed as a zero-emission system, it complies with all relevant EV regulations and standards.

The EM15 provides instant, silent torque ideal for urban and highway driving, requiring minimal routine maintenance. The primary service item is the reduction gearbox ATF, which must be changed per Genesis schedule using genuine fluid. Battery longevity is optimized by avoiding consistent 100% charging and minimizing DC fast charging in hot climates, as per TSB-22-EV-001. The system is sealed; no user-serviceable components exist within the motor or inverter.
Oil Specs: Reduction gearbox requires Genesis Genuine ATF (Genesis Owner's Manual).
Emissions: Certified as zero tailpipe emission under Euro 6d-TEMP-EVAP-ISC (VCA Type Approval #VCA/EMS/9012).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Genesis TIS Doc. EM15-010).

The Genesis EM15 was used exclusively in Genesis's flagship Electrified G80 sedan with rear-wheel-drive mounting. This motor received no major mechanical revisions affecting core compatibility during its 2021-2024 production. All software and minor hardware updates are documented in OEM technical bulletins.
Locate the motor identification plate on the side of the motor housing, which will list 'EM15' (Genesis TIS EM15-002). The 8th digit of the VIN is 'E' for all Electrified G80 models. The motor is mounted longitudinally at the rear axle, identifiable by its smooth, sealed aluminum housing with integrated cooling lines and high-voltage orange cabling. Differentiation from the dual-motor AWD variant (which uses an EM15 front and a more powerful EM16 rear motor) is clear: RWD models have only one motor at the rear. Service parts for the EM15 motor itself are generally not replaced individually; the entire drive unit is serviced as a module.
The EM15's primary reliability consideration is long-term high-voltage battery pack degradation, a factor for all EVs. Genesis service data indicates this is managed effectively by the BMS, while UK DVSA records show no significant pattern of related MOT failures. Adherence to recommended charging practices is the key factor in maximizing battery lifespan.
Analysis derived from Genesis technical bulletins (2021-2024) and UK DVSA failure statistics (2022-2024). Repair procedures should follow manufacturer guidelines.
