At the Genesis GV90 Tech Day held on the 27th at Incheon Yeongdong, lead designer of the Closer design team unveiled a fully re‑engineered “Dual‑Motion Hinges” system. Unlike previous technologies that required doors to be opened only by swing or slide mechanisms, this new method is engineered so that the two halves of the door operate independently and simultaneously without interference.
The key feature of the system is its use of a “B‑pillar” structure. The B‑pillar component does not simply lock the door; instead it incorporates a dual‑release controller that applies locking elements at both the upper and lower edges, enabling a “soft‑closing” function. Through this arrangement, the door moves smoothly at 70 cm per second and opens without any jerking motion.
Genesis also incorporated a reader sensor into the door‑opening process to detect nearby obstacles and uses a high‑strength steel tube connected to a “hidden lock‑case” structure so that the door can withstand impacts with no deformation. The system is capable of bearing forces above 14 tons, and has passed both internal evaluation and external certification tests, confirming its reliability.
The technology aims not merely at “fast followers” but at “fast movers,” offering a new experience beyond the simple opening mechanisms of existing brands. Genesis claims that by using the roof‑eave and spring‑housing structures first applied worldwide, it can complete the entire door operation in 0.08 seconds, positioning the GV90 as a top‑tier vehicle in the global automotive market.
