With E-GMP, the Ioniq 6 is one of few vehicles in the US with a fast 800-volt charging system, joining up with even fancier vehicles like the Porsche Taycan. Hyundai calculates that the battery can charge from 10 to 80 percent in just 18 minutes when connected to 350kW-capable charging stations. In colder weather, achieving the maximum charging speed requires the battery to be warm, so the Ioniq 6 can preheat the battery when navigation is pointed to a charging station.
