About the Hyundai IONIQ 6
The Hyundai IONIQ 6 is one of the most aerodynamic cars ever made, with a drag coefficient of just 0.21. That slippery shape translates directly into exceptional range — up to 382 miles WLTP, making it one of the longest-range EVs at its price point.
Built on Hyundai's E-GMP 800-volt platform, it charges remarkably quickly. A 10–80% DC fast charge takes just 18 minutes at up to 233 kW. The interior is spacious and lounge-like, with ambient lighting and sustainable materials throughout. The rear headroom is tighter than the IONIQ 5 due to the streamlined roofline, but four adults fit comfortably.
It competes directly with the Tesla Model 3 and BMW i4, offering superior charging speed and range while undercutting the BMW on price. The polarising styling won't suit everyone, but in terms of pure EV efficiency, it's genuinely outstanding.
What the press thinks
The IONIQ 6's aerodynamic shape delivers class-leading range and ultra-fast charging. Reviewers love the 800V architecture and relaxed driving character. Criticisms centre on the divisive styling, limited rear headroom, and a boot that's smaller than the numbers suggest.
