Hyundai RB (buses)

The Hyundai RB was a large commercial bus range from Hyundai Motor Company, licence-built on the frame, axles, bearings, engine and transmission of the Mitsubishi Fuso MP and MS rear-engine buses, with a domestically produced semi-monocoque body. Its successors were the Aero of February 1985 and the Aero City of February 1991. The RB520 city and express version appeared in April 1984, followed in October 1984 by the RB520L, a two-step low-floor city bus with a floor 20 cm lower than the FB485, a passenger stop bell, an automatic sliding centre door and safety mirrors. From February 1986 the MAN D0846HM engine was replaced by a Mitsubishi Fuso D6BR of 7,545 cc and 185 horsepower. Hyundai reached 94 percent local content and undercut Daewoo on price. The Aero City ended the RB in 1991.
