The Hyundai Ioniq 5 continues to be one of the best-selling non-Tesla EVs.

Hybrid trims of the models like the Hyundai Tucson and Kia Sportage saw record monthly sales.

The Kia EV9 comfortably outsold the mechanically similar Hyundai Ioniq 9.

The impressive sales streak for Hyundai and Kia's electrified vehicles rolled into May, with both brands posting record numbers across their electrified lineups.

Hyundai reported total sales of 87,468 units in the U.S. last month, a 3% growth year over year. The automaker said electrified vehicles, including hybrids, plug-in hybrids, and fully electric models, helped drive this growth.
