History of the Volvo B58

The B58 was Volvo’s mid-engined bus and coach chassis of the 1960s and 1970s, with the engine under the floor between the axles. It was made in Sweden from 1966 to 1982 and succeeded by the B10M, but it travelled much further than that: a Brazilian version, the B58E with B10M transmission and suspension, was built at Curitiba from 1979 to 1998.

Australia and New Zealand

The B58 was popular with Australian government operators. ACTION took 77 between 1972 and 1976, the Metropolitan Transport Trust in Tasmania 68 rigid buses and three articulated buses from September 1975, and the State Transport Authority in Adelaide 65 rigids and 35 articulated buses from April 1980. Private operators bought too, Forest Coach Lines 13, Busways 30 and Grenda 18. In New Zealand, 68 B58 trolleybuses ran in Wellington from 1981 until November 2009, originally for Wellington City Transport and finally for GO Wellington.

Brazil and Uruguay

Brazilian B58Es served city, coach and trolleybus work in São Paulo, Curitiba, Porto Alegre, Campinas, Sorocaba and Belo Horizonte. In 1992 the B58E became Brazil’s first bi-articulated chassis, 33 of which ran in Curitiba as express line buses. Chassis of Brazilian origin were bodied by Caio, Ciferal and Thamco for Montevideo, where CUTCSA acquired about 260 buses with Caio Vitória bodies, COETC 153 with Ciferal bodies, UCOT 118 and Raincoop 91.

In Sweden, the Greater Stockholm transport authority ordered 250 B58s in 1978. In Britain the chassis was sold to major operators including Wallace Arnold and Park’s of Hamilton from 1972, mostly as coaches; one was even rebodied as a double-decker with an East Lancs Droop Nose body for Skills Coaches.
