The first generation CL-Class was the sleek but hard-lined and redesigned W140-chassis (internally known as C140) coupé of 1992–1999. Designed by Bruno Sacco, the C140's final design was approved between late 1987 and early 1988. Though the coupé's physical appearance changed little over these years, the class underwent a name change several times. The V8 and V12 coupés were called the 500 SEC and 600 SEC, respectively, in 1992 and 1993. The 600 SEC was the first V12 coupé ever offered by Mercedes-Benz. For 1994, the model names were changed to the S500 Coupé and the S600 Coupé. The name CL-Class was adopted in June 1996 (1997 for MY1998 North American models), and the W140 coupés were called the CL500 and CL600. Production ended in August 1998.
