Mercedes-Benz OH

The Mercedes-Benz OH series are body-ready bus platforms with a rear engine, drum brakes and leaf or mixed (L) suspension, produced by Mercedes-Benz in Argentina and Brazil for the South American market since the early 1980s. Depending on the model they serve urban or short and medium-distance intercity use as basic, lower-cost platforms below the O 500 series, some with a high floor, some low and some in SB super-low versions widely used for accessibility in Buenos Aires and the rest of Argentina. OH stands in German for Omnibus Heckmotor, a bus with rear engine. Model codes follow the pattern of the firm's trucks: the first two digits give the gross weight in tonnes, the next two the engine power, L means air suspension and SB a super-low entrance, so the current OH 1621L-SB is rear-engined, 16 tonnes, 210 hp, air-suspended and super-low.
