Since the early days of the more comfort-oriented variants from the W 113 onwards, the typical Mercedes SL driver has enjoyed shifting gears automatically. However, there was always the manual alternative, which usually had four forward gears in the 1960s. What remained rare, however, was an actually very sensible variant from ZF with five gears, which allowed the engine, which was sensitive to engine speed, to be spared while at the same time being able to directly determine which gear ratio the car was currently running with. Just over one percent of all 280 SLs were equipped with the five-speed transmission, and this report is dedicated to one of these rare models.
