The Mercedes-Benz "Ponton" series are a range of sedans / saloon car models from Daimler-Benz, introduced starting in 1953, and subsequently nicknamed 'Ponton' (the German word for "pontoon"), referring to its ponton styling, a prominent styling trend that unified the previously articulated hood, body, fenders and runnings boards into a singular, often slab-sided envelope. At the time, Mercedes itself did not refer to any of its cars using the nickname. Mercedes stretched the 'Ponton' saloons into a range that became the automaker's dominant production models until 1959.
