1966 Mercedes-Benz 300 SE W109 (Manuals / 5 Gears) RWD (1965-1967)

The 1966 Mercedes-Benz 300 SE with 5-speed manual transmission represented the most technically refined variant of the W109 series for speed fans. This model used the ZF S5-20 gearbox, a rare and prestigious option that optimized the power of the legendary M189 engine . This 2996 cm3 petrol engine with aluminum block and mechanical injection Bosch produces 170 hp / 168 hp / 125 kW and a 249 nm torque . The fifth gear allowed the vehicle to reach a top speed of 200 km/h with lower engine torque, increasing acoustic comfort and highway efficiency. Like any W109, this version was equipped with pneumatic (airborne) suspension as standard equipment, offering a ride stability and smoothness that remains iconic to this day.
