![1982 Mercedes-Benz 280 S W126 (Manuals / 5 Gears) RWD [1979-1985]](https://i0.wp.com/i0.wp.com/autogalactic.al/wp-content/uploads/2026/01/abc-image.webp?fit=2048%2C822&ssl=1&resize=360,270)
The 1982 Mercedes-Benz 280 S with 5-speed manual gearbox is an optimized variant of the W126 series, which aimed to offer the prestige of an S-Class with higher fuel efficiency. This model is powered by the legendary M110 engine, a 2.8-liter (2746 cm3) dual-axle humpback unit ( DOHC ), which in this configuration uses the Solex 4A1 carburetor to produce 156 PS / 115 kW . The main feature of this version is the 5-speed Getrag 265 gearbox , where the fifth gearbox serves as an “overdrive,” reducing engine rides on the highway and significantly improving fuel consumption compared to the 4-speed version. With a time-advanced aerodynamic coefficient of 0.37 , the 280 S offers a smooth, sustainable and highly economical ride for its size.
