At the end of the 1963/1964 season, the 250 GTOs end their careers, and Ferrari looks for a replacement. Faced with the problems of homologating the 250 LM, Ferrari decided to promote the 275 GTB by building this prototype 08249 for Lorenzo BANDINI, which would be used to build the 12 GTB/C 66.

It features a slim aluminum body, a lightweight steel and aluminum structure, and a ribbed LM engine with 4 attachment points like the 12 in the 2nd "9000" series (see book: FERRARI 275 GTB by Jess G. POURRET).
