KAMM Tail is a car that sports a Kammback has an upright or chopped rear end. This is done to reduce the drag of the car. The studies say that a smooth, flat and well rounded body that is tapered like a teardrop or water drop at the rear that the car will have the better aerodynamic characteristics. Later, professor Wuunibald Kamm proved that long tapered tail was quite pointless.
Professor Wuunibald Kamm found that that cutting or flattening of the streamline end at an intermediate point would be beneficial. Another thing that can be beneficial that an edge of te streamline is end should be brought down towards the ground. With this the teardrop can be shaped without incurring such a large structural, material and size problem. The airflow, when given the proposition of the creation of a turbulence-eliminating streamlined in teardrop tail. It tends to flow in an estimate of that manner despite of the fact that the entire tail was not there. It is called the Kamm effect. This body style was used on many competition and high performance cars. Such cars are BMW 328, Ferrari 250 GT SWB Breadvan, Ferrari Dino, Alfa Romeo Montreal, Maserati Khamsin and many more.
