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.

Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface.
