Volvo B57 was a front-engined single-decker bus built by Volvo between 1960s and 1980s. It was equipped with the Volvo TD70-series engine. Volvo B57 could be built in 3 different wheelbase lengths: 5 metres (B57-50), 5.5 metres (B57-55) and 6 metres (B57-60). This vehicle was rare in the UK. Singapore Bus Services introduced them in the 1980s, and upon their retirement were eventually sold to Ireland and New Zealand.
