The Mercedes-Benz W115 is a series of executive sedans introduced in 1968 by Mercedes-Benz, along with the similar W114, to replace the earlier W110 series. They were manufactured until model year 1976, when the W123 was released. W115 models featured four-cylinder engines and were marketed with the model numbers 200, 220, 230 and 240, some of which may have a "D" appended to indicate the use of a diesel engine instead of a petrol engine. The series was designed by Paul Bracq, featuring a three-box design. At the time, Mercedes retailed sedans in two size classes, with the W114 and the W115 positioned below the Mercedes-Benz S-Class.
