Mitsubishi Buses

Aero Bus Series

Attaining New Heights in Touring Elegance

The oil crises of the 70s and a reassessment of the general quality of life had a very big impact on motor vehicle development. Among the environmental influences was the drive for cleaner air. To this end, Mitsubishi, a pioneer in the field of engine development, released three new direct injection diesel engines in 1975. These new engines combined with many other innovations, placed Mitsubishi in a very strong position when the new exhaust gas regulations for the domestic commercial market were enacted in 1979.

In 1982, Mitsubishi's large-size touring bus lineup underwent a full model change and was renamed the Aero Bus. An elegant, highly efficient aerodynamic form gave name to the bus series which was powered by either the 320ps, 8DC9 or the 290ps, 8DC8 direct injection diesel engines. Full independent air suspension provided a smooth gentle ride to dramatically increase passenger riding comfort and with the unibody construction, enhanced rigidity for added running stability was realized.

In 1985, the dual rear axle, double decker Aero King (MU) large-size bus was introduced to the market. It was powered by the 380ps, 8DC9, direct injection diesel engine. Two main saloon type models were produced with a passenger capacity of either 64 passengers or 60 passengers. The Aero King proved very popular and by 1988, Mitsubishi had secured over 50% of the double-decker bus market in Japan. Also in 1985, the long distance, high speed Aero Queen large-size bus was released. It was also powered by the 380ps, 8DC9 direct injection diesel engine and was used extensively on the long distance bus network of the Japan National Railways (JNR).
