2023 Hyundai Ioniq 6 — Should You Buy One?

Typical asking price: $32,000–$42,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A super-efficient, sleek electric sedan on Hyundai's excellent E-GMP platform — the Ioniq 6 offers long range, class-leading efficiency, and ultra-fast 800V charging (10-80% in ~18 min). It's one of the best-executed EVs going. A well-kept Ioniq 6 with a healthy battery and Hyundai's long warranty remaining is a superb, efficient used EV; verify battery health and charging, and note the swoopy roofline costs some rear headroom.
