Ponton (car)
Ponton or pontoon styling is an automotive design genre that spanned roughly from the 1930s-1960s, when pontoon-like bodywork enclosed the full width and uninterrupted length of a car body — eliminating previously distinct running boards and articulated fenders. The integrated fenders of an automobile with ponton styling may also be called pontoon fenders, and the overall trend may also be known as envelope styling.
