It is available with a variety of bodies such as the Van Hool T9 Alizee, Sunsundegui Sideral and Plaxton Panther/Paragon.

Large British users of the B12M include Wallace Arnold, Park's Motor Group and Southern Vectis.

Since 2011, the B12M was renamed as B340M, and the chassis was updated to the Proconve P7/Euro V emission standard rules in the following year.

Both articulated and bi-articulated versions are rated for 340 hp.

After Euro VI-based Proconve P8 emission standard became mandatory in Brazil in 2023, the B340M chassis was discontinued with no diesel successor being developed; instead, Volvo developed an electric bi-articulated bus chassis which belongs to the BZR range;[2] a single-articulated variant is presumably also in development.
