The 300 range was updated in 1952 with the introduction of a new platform that widely contributed to the vehicle’s popularity.
Unveiled at the Paris Auto Show in October 1951, the car sported a coupe body-type with a 2+2 seating configuration and styling similar to the previously released W186 models. Dubbed as the Cabriolet A, the car shared most of its underpinnings with the older version although the newly introduced triple Solex carburetors and nearly 8.1 compression ratio boosted the engine’s power output to 148 hp. The car was built in very few units until 1955 when it was revamped once more.
