The E-Gmp platform, introduced in 2021 by the Hyundai Group, serves as the unified base for all of its most recently developed electric vehicles
It was conceived with modularity and standardization in mind, enabling rapid development of a wide variety of vehicles, including high-performance models belonging to the “N” family, whose performance benchmarks were set at 0–100 km/h in 3.5 seconds and a top speed of 260 km/h.
This is achieved through compact “Power Electric” modules consisting of a motor, a transmission, and an inverter integrated into a single unit. The motor is controlled by the inverter’s power module, which uses silicon-carbide semiconductors, while the battery pack—modular in terms of capacity—can be charged at 800 or 400 volts without the need for external components or adapters. The multi-charging system is the world’s first patented technology to use the motor and inverter to switch between 400 and 800 volts, ensuring stable charging compatibility. As a result, the batteries can be charged from 10 to 80 percent in just 18 minutes, and up to 100 km of range can be recovered in five minutes.
Unlike conventional unidirectional systems, the “E-GMP” platform’s charging architecture includes an Integrated Charging Control Unit that enables the “Vehicle-to-Load” function, using the onboard battery to supply up to 3.5 kW at 220 volts to external electrical devices or even to recharge another EV. In terms of drivetrain layout, the platform is rear-wheel-drive by default but can support all-wheel drive by adding a second electric motor on the front axle. In this case, a disconnector manages the connection between the additional motor and the front wheels, enabling the transition between 2WD and 4WD to improve efficiency or performance depending on conditions.
Comfort, grip, and stability are ensured by a five-link rear suspension system, while battery safety is guaranteed by an ultra-high-strength steel structure reinforced with hot-stamped steel elements. Impact forces are absorbed by dedicated structures and by the central section of the battery pack, integrated into the vehicle body. The structure is further reinforced in the area ahead of the center console without compromising the body’s ability to prevent cabin deformation.
