After the evaluation of two Mercedes-Benz O305 double-deckers acquired c. 1982, Singapore Bus Services acquired 200 Mercedes-Benz O305 double-deckers which were very similar to KMB's O305. It features an 11,412 cc OM 407h engine with its modular W3D 080 R gearbox. With a licensed capacity of 109 passengers, the first of them entered service in 1984 and all of them retired in early 2000s.
