The Mitsubishi Fuso Aero King (kana:三菱ふそう・エアロキング) was a series of heavy-duty double-decker coaches built by Mitsubishi Fuso Truck and Bus Corporation. The Aero King first went on sale in 1984, after being introduced at the 1983 Tokyo Motor Show, and was discontinued in 2010, after five generations. It was either built as an integral bus or a bus chassis. The engines that were used in the Fuso Aero Bus were the 8DC9 (turbocharged V-8, 380 PS, used between 1984 and 1995 for MU515TA/MU525TA), the 8M21-3 (NA V-8, 420 PS/430 PS, used between 1995 and 2005 for MU612) and the 6M70-T4 (turbocharged L-6, 420ps, used between 2008 and 2010 for MU66JS).
