![1993 Mercedes-Benz 300 SD W140 (Automatic / 4 Gears) RWD [1991-1994]](https://i0.wp.com/i0.wp.com/autogalactic.al/wp-content/uploads/2026/01/abc-1_176791879069604cc672c58-1.jpeg?fit=1000%2C750&ssl=1&resize=360,270)
The 1993 Mercedes-Benz 300 SD for the US market represents a unique combination of the extreme luxury of the W140 series with diesel engine efficiency. This model was the first S-Class diesel limousine to be offered globally (initially for the US), using the well-known 3.5-liter Turbo-Diesel (OM603) six-cylinder in-line engine. With a power of 148 hp , this vehicle was not designed for dizzying speeds, but for an extremely smooth ride and long autonomy thanks to the 100-litre tank. The Cathedral’s royal construction, together with its double glazing and refined acoustic insulation, make the characteristic oil noise almost inaudible inside the cabin, offering the S-Class’s royal comfort at a lower fuel cost.
