![1966 Mercedes-Benz 300 SE W109 (Automatic / 4 Gears) RWD [1965-1967]](https://i0.wp.com/i0.wp.com/autogalactic.al/wp-content/uploads/2026/01/abc-18c0f2156d61f40a804188057136447dfe171aaf.webp?fit=1920%2C1440&ssl=1&resize=360,270)
The 1966 Mercedes-Benz 300 SE, equipped with the optional 3.69 axle and automatic gearbox, was the configuration intended to balance the relaxing nature of a limousine with the high-speed demands on the highway. This vehicle is powered by the legendary M189 engine, a 2996 cm3 Gasoline unit with aluminum block and mechanical injection Bosch, which produces 170 hp / 168 hp/ 125 kW at 5400 rpm and a 249 Nm torque at 4000 rpm. Thanks to the 3.69 -axis ratio, this car reaches a top speed of 195 km/h , correcting for the drop in speed that the standard automatic gearbox usually caused. Like any model of the W109 series, it comes with pneumatic (airborne) suspension that guarantees a smooth ride and maximum stability even at high speeds.
