Hyundai Motor Group runs one dedicated EV platform family in three variants, and its next step changes software and cost more than hardware
E-GMP launched in 2021 at 800 volts for the IONIQ 5, EV6 and GV60. From 2024 Kia used a 400-volt version for the cheaper EV3, EV4 and EV5, and Hyundai followed with the IONIQ 3 (built in Izmit, Turkey) in 2026. The E-GMP.S variant carries Kia's PV5 van from the Hwaseong EVO plant. Hyundai says the successor Integrated Modular Architecture (IMA) arrives around 2028, starting with a new IONIQ 5, stays at 800 volts and is less of a leap than E-GMP was.
IMA was announced in 2023 as two platforms - eM for passenger cars and eS for purpose-built vehicles - built from a standardized set of battery packs and motors shared across Hyundai, Kia and Genesis. The goal is cost: fewer pack and drive-unit variants, higher volume per component, and an architecture that lets the group swap cell chemistries, including LFP, without re-engineering each model. Hyundai still sells converted models alongside: the Kona Electric, Kia Niro EV, Hyundai Inster (Casper Electric) and Genesis Electrified GV70 and G80 use ICE-derived platforms.
The software change is larger. In 2025 Hyundai introduced Pleos, its software-defined vehicle brand: Pleos Vehicle OS for vehicle control and Pleos Connect, an Android Automotive infotainment system that debuted in Europe on the IONIQ 3. Software development sits with the group's 42dot subsidiary. Batteries come from SK On, LG Energy Solution and CATL; in the US the group has cell joint ventures with LG Energy Solution (HL-GA, Bryan County, Georgia) and SK On (Bartow County, Georgia) supplying the Hyundai Motor Group Metaplant America in Ellabell, Georgia, which builds the IONIQ 5 and IONIQ 9 with native NACS ports. In China, Beijing Hyundai and Kia build LFP-equipped models such as the Elexio and EV5 for local buyers.
