Military, Hyundai Motor and Mercedes-Benz showcase EVs, robot dogs and hydrogen trams at 'green mobility show'

"Smart Energy Plus 2026," co-hosted by MoneyToday and COEX and organized by the National Assembly Hydrogen Economy Forum, opens Wednesday at COEX Hall B in Seoul's Samseong-dong district, featuring a lineup of vehicles worthy of a green mobility show. The event runs through Oct. 30.

First, the Army will unveil its future mobility lineup. Through a dedicated booth, the Army plans to exhibit hydrogen-powered light tactical vehicles, small tactical vehicle generators with a rated capacity of 30 kilowatts (KW), trucks equipped with ESS (energy storage systems), and vehicle-mounted ESS units. This is intended to showcase the Army's future energy transition plan, centered on mobile microgrids.

The mobile microgrid to be exhibited at the venue features solar power generators, diesel generators, and an ESS installed on a vehicle. It is capable of maneuvering in rough terrain and can deploy a power grid swiftly within 100 minutes. Fixed equipment is used at garrisons, while mobile equipment is utilized in operational areas to reconfigure the power grid.

In the mobility zone of the exhibition hall, visitors can first encounter Hyundai Motor Group's future mobility technologies all in one place. On display are Hyundai Motor's hydrogen fuel cell vehicle 'The All New Nexo (Nexo),' Kia's first electrified PBV model 'The Kia PV5 (PV5),' and Boston Dynamics, the group's robotics subsidiary, quadruped walking robot 'Spot.'

In particular, Spot is scheduled to roam various parts of the exhibition hall during the three-day event to greet visitors. Spot supports tasks that are performed repetitively over long periods, such as detection, inspection, and patrol, in diverse industrial settings including energy, steel, and food sectors.

At the Hyundai Rotem exhibition booth, visitors can experience a hydrogen fuel cell tram, a future mode of transportation, via VR (virtual reality). When visitors wear VR equipment, they can directly enter the interior of a hydrogen fuel cell tram in a virtual space to check the comfort of the cabin and experience the driver's seat.

Hyundai Rotem will also demonstrate its multi-legged walking robot, developed entirely with domestic technology, at this exhibition. It is a domestically produced ground operation unmanned robot platform with key core components manufactured within the country, capable of overcoming vertical obstacles such as slopes and stairs and moving in harsh natural environments like shrubbery and mountainous areas. Equipped with daytime around cameras and nighttime close-range cameras, it can also be utilized for surveillance and reconnaissance.

In addition, on display are △Mercedes-Benz Korea's recently launched electric vehicle 'The All-New Electric CLA' in the domestic market, △two units of BMW Korea's popular electric vehicle 'The New BMW iX3,' △Audi Korea's electric vehicle 'Audi A6 e-tron,' △Porsche Korea's pure electric sports car 'Taycan GTS,' △Polestar Korea's electric vehicle 'Polestar 4 Coupe,' △Buick, GM's global premium automotive brand, PHEV (plug-in hybrid) 'Electra E7,' and △Lexus Korea's representative premium sedan ES, the fully redesigned 8th generation model 'All New ES 350e.'
