Mercedes-Benz OC500LE

From Wikipedia, the free encyclopedia

Transperth OC500LE (Volgren) serving as the Blue CAT.

The Mercedes-Benz OC 500 LE is a modular, heavy-duty, twin-axle bus chassis produced by Mercedes-Benz/EvoBus in Sámano, Spain. It was designed as a base for low-entry city, suburban, and intercity buses weighing a maximum of 18,000 kg. It has much in common with the chassis used for the Mercedes-Benz Citaro integral bus range. The engine is horizontally-mounted over the rear overhang of the vehicle as opposed to vertically-mounted like in the Citaro chassis.

Large numbers of buses built on the OC 500 LE chassis can be found in Australia, where it is marketed as the "O 500LE". Particularly notable are the OC 500 LE/Volgren CNG-fuelled buses currently being delivered to the city of Perth in Western Australia for operation on the Transperth suburban bus network.
