Mercedes-Benz W116 (1972–1980)

The Mercedes-Benz W116 was the first car to officially carry the S-Class designation, launched in 1972. It set new standards for passive safety, comfort and refinement in the luxury car class. The range spans the six-cylinder 280S and 280SE through to the V8 350SE, 450SE and 450SEL, culminating in the extraordinary 450SEL 6.9. The 6.9, with its 6.8-litre V8 engine and self-levelling hydropneumatic suspension, remains one of the most remarkable luxury cars ever produced — faster than most sports cars of its era while offering limousine comfort. The W116 is exceptionally durable when properly maintained. Rust in the rear wheel arches and lower sills is the main concern. The Mercedes-Benz Club and specialist suppliers provide comprehensive support.

Available body styles: Saloon. Produced from 1972 to 1980.
