Home / SMRT Buses, Singapore (before GCM/BCM) / Mercedes-Benz O530 Citaro / Batch 1 51

Following a successful trial on the demonstrator unit SMB136C, SMRT Buses made an initial order for 10 Citaros (Mk II or facelift version), known as Batch One. They were registered SMB139U to SMB148T. On 21 March 2011, these production batch buses began their debut on services 75, 531, 920 and RWS8 Staff.

Changes to the production batch Citaros are mainly aesthetic and the automatic transmission used - the production units were fitted with Lawo BENEFIT EDS (notably with route details on the side EDS), seat covers in its corporate livery and swing-out doors. SMRT Buses retained its option of the OM906hLA engine (6,374cc) and uses the new generation ZF EcoLife 6AP 1200B (6-speed automatic) gearbox for Batch One except SMB148T. The interior is fully low-floor and its air-conditioning was supplied by Konvekta.
