The Volvo B9L (also known as the Volvo 7500, Volvo 7700 or Volvo 7900 for integral models) was a low-floor single-deck bus chassis constructed by Volvo Buses since 2005, replacing the Volvo B7L and Volvo B10L. An articulated model, known as the Volvo B9LA, is also available. It was superseded by the Volvo B5LH in Europe.
The engine is mounted vertically on the rear left overhang of the chassis similarly to with the B7L, allowing B9Ls to be low-floor throughout the whole length of the bus due to a lack of underfloor equipment. The Volvo B9L is available as an integral bus bodied by Volvo (7500/7700/7900) or as a chassis only, with bodies by other manufacturers.
Large orders for B9Ls were placed in Malmö, where they form the majority of the fleet, as well as in Stockholm, Kristianstad, and Örebro. Despite this overall sales of the B9L were poor, especially outside of Sweden, with many operators instead preferring the existing B7RLE or new B9S. Outside of Europe, ComfortDelGro Bus of Singapore had also purchased a fleet of SC Auto-bodied B9Ls in 2015 for its National University of Singapore internal shuttle service.
