|Body and chassis|
The Ponton was Daimler-Benz's first totally new Mercedes-Benz series of passenger vehicles produced after World War II. In July 1953, the cars replaced the pre-war-designed Type 170 series and were the bulk of the automaker's production until 1959, though some models lasted until 1962.
The Ponton models were replaced by the "Heckflosse" or "Fintail" models
Daimler-Benz emerged from World War II as a carmaker best known in the early 1950s for its expensive Mercedes-Benz 300 Adenauers and exclusive Mercedes-Benz 300 S sports tourers. Both were largely handbuilt body on frame vehicles. Its low end was anchored by the dated pre-war designed Type 170.
Seeking to expand its production boldly, Mercedes turned toward the unibody concept to design a line of mass produced autos that would be rugged, reliable, and both relatively simple and inexpensive to build.
Work began in earnest on the pontons bodied cars in 1951, with a design focused on passenger comfort and safety. Head of the design team was Dr. Fritz Nallinger. Styling was headed by Karl Wilfert. Part of the design team was Béla Barényi. Barényi integrated into the "three-box design" the concepts of crumple zones and the non-deformable passenger cell. The crumple zones patent 854157, granted in 1952, describes the decisive feature of passive safety. Barény questioned the opinion prevailing until then that a safe car had to be rigid. He divided the car body into three sections: the rigid non-deforming passenger compartment and the crumple zones during collision. This design concept was proven by ADAC crash test facility in June, 2010 when a Mercedes Ponton was crash tested in their Technical Centre in Landsberg am Lech, confirming the existence of the design incorporated into the vehicle. This made for a milestone in car design with front and rear crumple zones for absorbing kinetic energy on impact.
There were essentially four types of Ponton cars. Note the "D" designates a diesel engine, and the suffix "b" and/or "c" are body variants introduced after the middle of 1959.
