Manufactured between 1973 and 1981, the W116 sedan epitomized Mercedes-Benz's engineering prowess by introducing various groundbreaking advancements in safety and performance. This model notably marked the debut of the initial turbocharged diesel sedan, pioneered the implementation of the first airbag, and introduced the concept of ABS, which would become commonplace in the following decades. Of particular note, the 6.9L supersedan stands out as our preferred iteration of this lineup.
