Mercedes-Benz CL-Class Coupé (C140) (C140)

If the W140 sedan was Mercedes-Benz at its most imposing, the C140 coupé was the same statement carved into two doors — massive, silent, and available with a V12 that made everything else on the autobahn feel provisional.

The SEC coupé had its world premiere in January 1992 in Detroit and its European debut at Geneva two months later, reaching series production that October as the 500 SEC and 600 SEC. It shared the W140’s over-engineered platform, double-pane glass and obsessive noise insulation, but wore a body of its own: frameless windows, no B-pillar, and a shorter 2,944 mm wheelbase. June 1993 brought the corporate renaming to S 500 Coupé and S 600 Coupé, and in March 1994 the 4.2-liter S 420 Coupé arrived as the entry model.

In June 1996 the line was renamed CL-Class and spun off from the S-Class hierarchy as the CL 420, CL 500 and CL 600. Production ended in September 1998 after 26,022 cars, making the C140 the last hand-built S-Class coupé before the C215 adopted a more contemporary design language.
