![1993 Mercedes-Benz S 320 W140 (Automatic / 5 Gears) RWD [1991-1994]](https://i0.wp.com/i0.wp.com/autogalactic.al/wp-content/uploads/2026/01/abc-9490761cad2ba834a8f2377d8ac9ac181e6133f1-1.webp?fit=600%2C338&ssl=1&resize=360,270)
The 1993 Mercedes-Benz S 320 with 5-speed automatic gearbox represents the pinnacle of refinement for the six-cylinder engines of the W140 (Phase-I) series. This model, introduced during the renaming period of the S-class, benefits from the advanced Bosch HFM engine management system, which optimizes the performance of the 3.2-liter M104 engine . The device with the fifth gear “overdrive” not only improves fuel economy at high speeds, but makes the journey even more smooth by lowering the engine rotations. With insulating double glazing and a chassis that offers an unprecedented cruise over the road, the S 320 remains the royal limousine that set German luxury and engineering standards for the 1990s.
