WLTP range of 317 miles, 80% fast-charging time of 18 minutes, 0-62 mph acceleration time of less than 3.5 seconds and top speed of 162 mph are the top specifications Hyundai Motor Group (HMG) is claiming for E-GMP-based EVs as it reveals the new platform globally today. The US-bound Hyundai Ioniq 5 will be the first recipient of the E-GMP-based EV. Check out the dedicated EV platform in the video at the 0:58 mark:

HMG says that E-GMP (Electric-Global Modular Platform) will serve as the core technology for the Hyundai Ioniq 5, Hyundai Ioniq 6 and Hyundai Ioniq 7 and all other next-gen Hyundai, Kia and Genesis pure electric models. The rear-wheel drive based dedicated EV platform would offer improved driving and cornering performance and stability compared to today’s Hyundai and Kia EVs, which sit on a platform engineered predominantly to accommodate internal combustion engines.
E-GMP features a five-link rear suspension, usually seen in the platforms of mid-size and larger vehicles. The Ioniq 5 and the Kia CV would be compact EVs and still benefit from a five-link rear suspension. Another highlight of E-GMP is an integrated drive axle or IDA, which combines wheel bearings with the driveshaft to transmit power to the wheels.
The battery packs of E-GMP EVs will have around 10% improvement in the energy density compared to existing EV battery technology. So, they will be lighter, and it will be possible to mount them lower and free up more cabin space. The Hyundai Ioniq 5 is said to come with 58 kWh and 73 kWh battery pack options.
800V charging capability will be standard, and so, in locations having high voltage EV charging infrastructure, customers will be able to fast-charge with up to 350 kW output. It will take just 5 minutes to charge up to the level that gives a range of 62 miles. Fast-charging to 80% SoC will be a matter of just 18 minutes. Expect these parameters in the US-bound Hyundai Ioniq 5. The 0-62 mph acceleration time of 3.5 seconds and the top speed of 162 mph are of a secret “high performance model”, though, and we expect that to be a flagship Genesis sports coupe. The EPA-estimated Hyundai Ioniq 5 range should be close to 300 miles.
E-GMP has a new power electric (PE) system that comprises a motor, a transmission and an inverter integrated into a single compact module. Integrating the components this way raises the motor’s maximum speed by up to 70 percent compared to existing motors. All-wheel drive configuration will be available in E-GMP models, with an additional motor.
One more feature of E-GMP worth noting is the Integrated Charging Control Unit or ICCU, which allows a new vehicle-to-load or V2L function. Here it will be possible to charge another EV using the energy from the Hyundai Ioniq 5’s battery pack without additional components. It will be possible to supply up to 3.5 kW of power using the V2L function. This means the ability to operate household components like an air conditioner or a TV for a whole day using the EV’s stored energy.
The Hyundai Ioniq 5 is likely to debut in early 2021 and go on sale in the U.S. market as early as late 2021.
