Volvo B57 was a front-engined single-decker bus chassis manufactured by Volvo between 1966 and 1982. Since 1970 it was also available as the Volvo BB57, with the engine mounted on top of the front axle, giving the buses very little front overhang. The BB57 became a kind of replacement for the smaller B54, but as it was larger, the B54 got its true replacement later. The predecessor to BB57, the B615 had gone out of production in 1965, but apparently the demand for such a model was so high that they had to bring it back almost half a decade later, as the B54 proved to be too small.

Both B57 and BB57 could be built in three different wheelbase lengths: 5 metres (B57-50), 5.5 metres (B57-55) and 6 metres (B57-60).

This chassis type was rare in the United Kingdom, but was quite popular in rural parts of the Nordic countries.

Singapore

Singapore Bus Service introduced a fleet of 350 New Zealand Motor Bodies bodied B57s between 1980 and 1983 following a successful trial of a Metal Sections-bodied demonstrator in 1979. Of these, the first 200 units were fitted with Version 1 of the bodywork, which hard a raised angular roof for the front destination signage, and the balance 150 units fitted with Version 2 of the bodywork, which had a curved roof for the front destination signage. [2][3][4][5] All units were retired and sold to Bus Éireann, Ireland between 1994 and 1998 for use on school bus duties in rural areas.

Pakistan

In Pakistan, the Punjab Urban Transport Corporation placed 300 in service in Lahore.[6][7]

Australia

In Australia, four B57s were purchased by Neville's Bus Service[8] while another was purchased by Cairnstrans.[9]

Volvo B57 — шасси, на котором строили свои автобусы различные автопроизводители, выпускаемое шведским автопроизводителем Volvo Bussar в период с 1966 по 1982 год параллельно с Volvo B58. С 1972 года оно также было известно как Volvo BB57 с двигателем, установленным поверх передней оси, что давало автобусам наименьшую нагрузку. BB57 пришло на смену B54, но с учётом габаритов, B54 было снято с производства гораздо позже. Предшественник BB57, B615, был снят с производства в 1965 году, но спрос на такую модель был настолько высок, что им пришлось вернуть его почти через полдесятилетия, так как B54 оказался слишком малогабаритным.
