Hyundai Blue City

The Hyundai BlueCity was a large-class commercial bus that Hyundai developed on the basis of the Hyundai Aero City and offered as a CNG hybrid. A low-floor version came first, and in 2015 a high-floor CNG hybrid version built on the Aero City was developed and shown at national demonstrations. It used the 240 horsepower G240 CNG engine that it shares with the Green City, assisted by a 60 kW electric motor and a 3.8 kWh lithium polymer battery, and its CNG tanks gave 340 km of range per fill. The article records slow acceleration, weak hill climbing, an idle-stop system that drivers and passengers disliked and frequent faults, which depressed sales and led many operators to replace their buses early, and it says production ended in 2019 after a defect was found in the automated manual transmission. A low-floor BlueCity was chosen for the Sejong BRT route between Banseok Station and Osong Station.
