The luxury series of the W111, called W112, was presented in 1961 with the 300 SE version. In 1963 it was the turn of the long wheelbase configuration of the 300 SE, whose engine continued to evolve, reaching 170 hP in 1964, thus offering performance quite close to the 600, presented practically in the same period. The W112 series was replaced in 1965 by the W108/W109 family.
