The Hyundai Ioniq 6 will be introduced as a sedan, as opposed to the current Ioniq 5, which as you know, received rage reviews and won Car of the year awards in numerous countries.
Expect to be available in at least 77kWh with better efficiency in comparison to Hyundai Ioniq 5 due to the sleeker sedan design a.k.a better aerodynamic efficiency.
Do expect the availability as early as Q1 2023.
