The Hyundai IONIQ 6 (Generation I, code CE) is a 100% electric sedan based on the Hyundai-Kia group's E-GMP modular platform. Dubbed the "Electrified Streamliner" by the manufacturer, it stands out with its ultra-aerodynamic teardrop design (drag coefficient of 0.21), giving it remarkable energy efficiency and excellent highway range. It benefits from the 800-volt architecture, allowing for ultra-fast charging (10 to 80% in 18 minutes on an Ionity charger). Although praised for its comfort, soundproofing, and onboard technologies, it suffers from an impractical trunk (no tailgate) and limited rear headroom. In terms of reliability, the E-GMP platform is generally robust, but it is marred by recurring issues related to the ICCU (Integrated Charging Control Unit) and 12V battery management,
The Hyundai IONIQ 6 is a brilliant electric sedan, offering formidable efficiency and some of the best charging speeds on the market thanks to its 800V architecture. It is an excellent alternative to the Tesla Model 3 for those who prioritize comfort, stylistic originality, and legroom. However, its reliability record is tarnished by the endemic ICCU (charging and 12V battery management) issue affecting the E-GMP platform. Buying used is recommended, but on one strict condition: you must imperatively verify that the vehicle has undergone all recall campaigns (software updates and/or hardware replacement of the ICCU). Favor the 77.4 kWh RWD version for the best range/price compromise.
