Hyundai Motor's "trailer drone" on Sept. 8 is displayed at the 2021 H2 Mobility + Energy Show at the Korea International Exhibition Center aka KINTEX in Goyang, Gyeonggi-do Province. Powered by hydrogen fuel cells, the eco-friendly vehicle has a trailer on top of two "e-bogies" with a fully autonomous operating system, enabling turns with a narrower radius than ordinary trailers. Bogie is a chassis with wheels attached to the bottom of the vehicle.
