The 1966 Mercedes-Benz 300 SE for the North American market was the epitome of European luxury tailored to American standards, positioning itself as a direct competitor to the best domestic limousines. This model is powered by the legendary M189 engine, a 2996 cm3 Gasoline unit with aluminum block and mechanical injection Bosch, which according to the SAE standards of the time produced 195 HP / 198 PS / 145.5 kW at 5500 engine rpm and a 276 Nm torque at 4100 rpm. Equipped with the 4-speed automatic transmission and pneumatic suspension (airborne) as standard equipment, this sedan offered an exceptionally smooth ride, ideal for long-distance American routes. With a top speed of 185 km/h and a 0-60 mph acceleration in 9.9 seconds , it combined solid performance with a refinement that few cars at the time could match.
