It's official: The 2025 Hyundai Ioniq 5 N, the new hot-rod version of Hyundai's Ioniq 5 electric SUV, is the quickest SUV MotorTrend has ever put through its instrumented testing. Not the quickest electric SUV, or the quickest SUV from a non-exotic brand, or the quickest SUV with a snazzy blue paint job, but the quickest SUV. End of sentence.
