The Mercedes-Benz 600SEC was a variant of the C140 S-Class Coupe that was introduced for the 1993 model year. This series of luxury coupes were powered by Mercedes' M120 E60 engine, which was a 6.0L V12 that generated 400hp. The 600SEC became known as the S600 Coupe in 1993 when Mercedes changed their naming conventions, although the car offered remained the same.
