The Neoplan Centroliner is a series of low-floor transit buses which was first unveiled in 1997, and mainly built by Neoplan Bus GmbH for the European market. At the time when it was first released, it adopted contemporary technologies like Controller Area Network. The product range of Centroliner included: midibus, full-size/articulated single-decker, and three-axle double-decker, in different body lengths. The rigids had 1 door, 2 door or 3 doors whereas the articulated have 2 doors, 3 doors or 4 doors. After the acquisition of Neoplan by MAN AG subsidy MAN Nutzfahrzeuge AG, a new version of Centroliner full-size/articulated single-decker was launched, it was also known as Neoplan Centroliner Evolution and was based on MAN Lion's City with different bodywork. After restructuring of MAN's bus division in 2009, Neoplan is concentrating exclusively on luxury coaches and due to that, Centroliner was discontinued without Neoplan-branded successor. Instead, MAN promotes Lion's City as its successor.
