Hyundai has released a mysterious 15-second teaser video hinting at a "major global debut" at this week's New York International Auto Show. The clip shows a cubic rock rotating in a desolate landscape, with a person walking toward the camera—creating a distinctly futuristic atmosphere. Speculation is mounting that the reveal could be linked to the previously unveiled Crater concept vehicle or signal the imminent production of a rugged off-road SUV. Hyundai has not disclosed specific details yet, only confirming that the unveiling will take place on Wednesday, April 1, at 9:55 a.m. Eastern Time, and will be streamed live on YouTube. If the Crater concept reaches production, it would fill a gap in Hyundai’s lineup within the currently popular off-road SUV segment.
