An articulated version of the B10L, known as the B10LA, was also produced.It was available in the United Kingdom and Ireland between 1994 and 1999, with a choice of two types of bodywork, the Alexander (Belfast) Ultra and the Wright Liberator. The Alexander Ultra body was based on the Swedish design produced by Säffle (a subsidiary of Volvo), who built the body on the first B10L imported to Britain. The Wright bodywork proved slightly more popular.
