From October 1992 to June 1993, all S-class coupes were designated SEC. For example, 500 SEC or 600 SEC. From June 1993 to June 1996, the large coupes were called the S Coupe. For example, the S600 Coupe. From June 1996 until the end of production, all S-class coupes C140 began to belong to a separate CL-class. For example, CL 500 or CL 600. The V12 M 120 engine was an entirely new design, not just the first series-produced twelve-cylinder Mercedes-Benz passenger car, but also the most powerful Mercedes-Benz car engine of its day, with a rated power output of 300 kW (408 hp). With a peak torque of 580 Newton meters, it reached the 500 Newton meters mark at 1600/min. The M 120 was the only twelve-cylinder engine worldwide to feature this cylinder-selective anti-knock control. This alone made possible the high compression ratio of 10:1, necessary for optimum use of fuel. #s600coupe #c140 #v12engine #oldbenz source: Next Classics
