It has been commercialized in Sweden, where it has been in use in the urban systems of Stockholm, Östergötland, Umeå and Gothenburg, being used there as a rapid transit buses; in Chile where it was a part of the biggest purchase order for Volvo buses: 1,159 articulated units entrusted for the urban system of Santiago; and in Brazil to be used in urban system of Sao Paulo by rapid transit corridors, in articulated and bi-articulated versions.

The new chassis was conceived as a mid-engined articulated bus, with low floor at least in 40% of its length and an engine of less than 10 liters of displacement.

Initially made in the Volvo Buses plant in Borås, Sweden, it was offered in two versions: They were offered with a frontmost section wheelbase of 6.4 meters and bodied by Säffle, as a complete Volvo 7500 bus.

In 2005, the platform's production was extended to Volvo Buses' factory in Curitiba, Brazil, which accommodated an order of 1,159 B9SALF units for the urban system of Santiago, Chile.

The order required the modification of the frontmost section to 5 meters to avoid problems of maneuverability in narrow streets.
