The Volvo B58 is a mid-engined bus chassis built by Volvo of Sweden from 1966 until early 1982. It replaced the shortlived Volvo B755 and was itself the forerunner to the highly successful Volvo B10M.
In the United Kingdom, it was sold to many major operators including Wallace Arnold and Park's of Hamilton. Many of the Volvo B58s in UK were built as coaches. Its main rival was the Leyland Leopard.
A special version of the B58 was produced in cooperation with swiss company Hess, in witch the diesel engine was exhanged with BBC electrics to become a trolleybus. Wellington in New Zealand also runs around 59 of these Volvo B58 trolleybuses. Originally with 68, some have been scrapped for spare parts & some have been preserved. As they are around 23 years old, they are in need of renewal and vital parts (traction motor, axles etc.) are being used combined with new parts to make new trolleybuses. 3 prototypes have already been made.
