Mercedes-Benz S-Class Sedan (W126)

The W126 S-Class refined the formula the W116 established — a lighter, more aerodynamic flagship that dominated the luxury saloon market through the 1980s with engineering restraint and unmistakable presence.

Six-cylinder 260 SE and 300 SE models served the entry luxury buyer, while 380 SE, 420 SE, 500 SE, and 560 SE V8s covered the upper range. The 300 SD turbo diesel brought oil-burning S-Class motoring to America, and the SEC coupé on C126 shared the same platform with pillarless glamour. Anti-lock brakes, airbags, and improved corrosion protection made the W126 the S-Class many owners still consider the high-water mark.

Production over 1979–1992 came to 490,905 cars.

Year by year.

The material factory changes, safety upgrades and visual cues that separate early and late W126 saloons.

  2. 1981
    • The Energy Concept revision altered the V8 engines for lower fuel consumption and stronger low-speed torque.
    • A driver airbag became available with a seat-belt tensioner for the front passenger.
  3. 1985
